the amount of cereal that can be poured into a small bowl varies with a mean of 1.5 ounces and a standard deviation of .3 ounces. a large bowl holds a mean of 2.5 ounces with a standard deviation of .4 ounces. you open a new box of cereal and pour one large and one small bowl. what is the standard deviation of this difference?

Answers

The required difference between the amount of cereal poured into a large and small bowl representing the difference of standard deviation is equal to 0.5 ounces.

Let X be the amount of cereal poured into a small bowl.

And Y be the amount of cereal poured into a large bowl.

Then, the standard deviation of the difference Y - X.

Mean of X is given as 1.5 ounces

Standard deviation of X is 0.3 ounces

Mean of Y is given as 2.5 ounces

Standard deviation of Y is 0.4 ounces

The difference between Y and X can be written as Y - X.

Mean of Y - X is given by the difference of the means,

= 2.5 - 1.5

= 1 ounce.

As we assume that X and Y are independent.

Variance of Y - X can be calculated as the sum of the variances of Y and X.

Thus, we have,

Var(Y - X) = Var(Y) + Var(X)

⇒Var(Y - X) = (0.4)^2 + (0.3)^2

⇒Var(Y - X) = 0.16 + 0.09

⇒Var(Y - X) = 0.25

The standard deviation of Y - X is the square root of the variance, so we have,

SD(Y - X) = √(Var(Y - X))

⇒SD(Y - X) = √(0.25)

⇒SD(Y - X) = 0.5

Therefore, the standard deviation of the difference between the amount of cereal poured into a large and small bowl is 0.5 ounces.

Jenny walks to softball practice on Friday, She leaves her home and walks 10 blocks north. She then turns west and walks 4 more blocks to the softball field. How far diagonally is the softball field from Jenny’s home? If she takes the diagonal path home, how far does she walk in total to practice and home?

Answers

Answer:

We can use the Pythagorean theorem to calculate the distance diagonally from Jenny's home to the softball field.

The distance she walks north is 10 blocks, and the distance she walks west is 4 blocks. Using the Pythagorean theorem, the diagonal distance is:

√(10² + 4²) = √116 ≈ 10.77 blocks

To find the total distance she walks to practice and back home, we need to double the diagonal distance:

2 × 10.77 ≈ 21.54 blocks

Therefore, if Jenny takes the diagonal path home, she will walk approximately 21.54 blocks in total to practice and back home.

The measure of an exterior angle of a triangle is always
A. Greater than its adjacent interior angle.
B. Less than its adjacent interior angle.
C.greater than either remote interior angle.
D.less than either remote interior angle.

Answers

A. Greater than its adjacent interior angle. The measure of an exterior angle of a triangle is always C. greater than either remote interior angle.

An exterior angle is formed by extending one side of a triangle. In a triangle, the exterior angle is equal to the sum of the two remote interior angles (the two angles that are not adjacent to the exterior angle).

Therefore, the exterior angle will always be greater than either one of the remote interior angles.

The exterior angle theorem states that when two sides of a triangle are adjacent, the resulting exterior angle is equal to the sum of the degrees of the two interior angles of the triangle. This theorem can be used to find the measure of an unknown angle in a triangle.

Answers

There are basically 6 ratios used for finding the elements in Trigonometry. They are called trigonometric functions. The six trigonometric functions are sine, cosine, secant, cosecant, tangent and cotangent.

By using a right-angled triangle as a reference, the trigonometric functions and identities are derived:

sin Î= Opposite Side/Hypotenuse

cos Î= Adjacent Side/Hypotenuse

tan Î= Opposite Side/Adjacent Side

sec Î= Hypotenuse/Adjacent Side

cosec Î= Hypotenuse/Opposite Side

cot Î= Adjacent Side/Opposite Side

All these are taken from a right-angled triangle.

When the height and base side of the right triangle are known, we can find out the sine, cosine, tangent, secant, cosecant, and cotangent values using trigonometric formulas.

The reciprocal trigonometric identities are also derived by using the trigonometric functions.

78/100

Step-by-step explanation:

Since .78 is in the hundredths place just move the decimal two places to the right then put it over 100. But idk if you mistyped this because .78 is not a repeating decimal

Answer:

6/9

Step-by-step explanation:

Change 0.7878 to a fraction.

Let n = 0.7878... Multiply both sides by 100 (by 100 when there are two repeating decimal digits)

100n = 78.7878... Subtract n from 100n.

99n = 78 Divide both sides by 99

n = 78/99 but n is 0.7878..., so

0.7878... = 78/99

Similarly with 0.66...

Let n = 0.66... Multiply both sides by 10 (by 10 when there is only one repeating digit)

10n = 6.66... Subtract n from 10n.

9n = 6 Divide both sides by 9.

n = 6/9 but n is 0.66..., so

0.66... = 6/9

where:

m is the slope and b is the y-intercept.

Hence, interpreting the above question:

On a two-week job, a repairman works a total of 70 hours,He charges 75$ plus 40$ per hour.

x is the number of hours and y is the total fee.

Hence, the Equation we have is:

y = $40 × x + 75

y = 40x + 75

12. Calculate

(a) the consumer’s surplus

(b) the producer’s surplus assuming pure competition

Answers

The given demand and supply of the function has ,

Equilibrium price is Rs. 14 and the equilibrium quantity is equal to 40 units.

The consumer surplus for the given function is Rs. 1,080.

The producer's surplus for the given function is Rs. 40.

Demand of the function 'Qd' = -2P + 68

Supply  of the function 'Qs' = 2P + 12

The equilibrium price and quantity by setting the demand equal to the supply.

⇒ Qd =  Qs

Setting Qd equal to Qs, we get,

⇒-2P + 68 = 2P + 12

Solving for P, we get,

⇒4P = 56

⇒P = 14

Substituting P back into either the demand or supply equation, we get,

⇒Qd = -2(14) + 68

        = 40

⇒Qs = 2(14) + 12

        = 40

So the equilibrium price is Rs. 14 and the equilibrium quantity is 40 units.

The consumer's surplus,

= The area below the demand curve and above the equilibrium price.

Consumer's surplus

= (1/2) x (Equilibrium quantity) x (Difference between maximum price and equilibrium price)

⇒ Consumer's surplus = (1/2) x (40) x (68 - 14)

⇒ Consumer's surplus = Rs. 1,080

The consumer's surplus is Rs. 1,080.

The producer's surplus

= The area above the supply curve and below the equilibrium price.

⇒ Producer's surplus

= (1/2) x (Equilibrium quantity) x (Difference between equilibrium price and minimum price)

⇒ Producer's surplus = (1/2) x (40) x (14 - 12)

⇒ Producer's surplus = Rs. 40

The producer's surplus is Rs. 40.

Therefore, for the given demand and supply function we have,

Equilibrium price and the equilibrium quantity is equal to Rs. 14 and 40units.

Consumer’s Surplus  is Rs. 1,080.

Producer's surplus is Rs. 40.

The point of intersection of straight line is( 2 , 0 ).

What is a straight line, exactly?

Simply put, a straight line is a line devoid of bends. A straight line is one that does not curve and reaches to infinity on both sides.

When x = 0 , y = 7 ,  so c= 7

When y = 0, so x = 2     0 = 2m + 7

so the value of m = 7/-2

3) A ( 0,7 )    B ( 2 , 0 )

the mid point of the segment AB means ( 0 + 2 /2 , 0+7/2) = ( 1, 7/2)

so,   y = -7/2x + 7

b the point ( -2, k ) when x = -2  k = -7/2 * (-2) + 7 = 14

simultaneous  equations =   y = x- 2

                                                y = -7/2x + 7

so x= 2 & y = 0

You have 95 coins, consisting of nickels, dimes, and quarters. The value of the coins is $13. 70. There are 11 more quarters than dimes. Which system of equations can be used to represent this situation, where n is the number of nickels, d is the number of dimes, and q is the number of quarters?.

Answers

So, the system of equations representing this situation is: n + d + q = 95; 0.05n + 0.10d + 0.25q = 13.70; q = d + 11.

To represent this situation with a system of equations, we can use the following equations:

The total number of coins: n + d + q = 95

The total value of the coins in dollars: 0.05n + 0.10d + 0.25q = 13.70

The relationship between the number of quarters and dimes: q = d + 11

The first equation represents the total number of coins, which is given as 95.

The second equation represents the total value of the coins in dollars, which is given as $13.70. The values of each coin (nickel, dime, quarter) are multiplied by their respective quantities (n, d, q) and summed up to obtain the total value.

The third equation represents the relationship between the number of quarters (q) and dimes (d), which states that there are 11 more quarters than dimes.

Put value of y in equation (2)

5x + 10( 350 - x) = 2000

5x + 3500 - 10x = 2000

-5x = -1500

x = 300

In the afternoon, she made 4 small trays and 1 large tray, which contain a total of 116 cookies. How many cookies do the different sized trays contain?

Answers

Answer:

The amount of cookies in the small tray = x = 19 cookies

The amount of cookies in the Large tray = y = 40 cookies

Step-by-step explanation:

Let

The amount of cookies in the small tray = x

The amount of cookies in the Large tray = y

We are told:

A caterer is making cookie trays for upcoming holiday parties.

This morning, she made 4 small trays and 4 large trays, which contain a total of 236 cookies.

This is represented Mathematically as:

4x + 4y = 236..... Equation 1

In the afternoon, she made 4 small trays and 1 large tray, which contain a total of 116 cookies.

This is represented Mathematically as:

4x + y = 116 ........ Equation 2

y = 116 - 4x

We solve the above equations using the substitution method

We substitute 116 - 4x for y in Equation 1

4x + 4y = 236..... Equation 1

4x + 4(116 - 4x) = 236

4x + 464 - 16x = 236

Collect like terms

4x - 16x = 236 - 464

-12x = -228

x = -228/-12

x = 19 cookies

Solving for y

y = 116 - 4x

y = 116 - 4 × 19

y = 116 - 76

x = 40 cookies

The number of cookies the different sized trays contained is given as:

The amount of cookies in the small tray = x = 19 cookies

The amount of cookies in the Large tray = y = 40 cookies

b. Which combination of the independent variables would you suggest the estimator use? What is the estimated regression equation for this model and what is its adjusted R2 value?
c. Suppose the estimator wants to use total units of work (X2) and city/location of work (X5) as the only independent variables for the regression model to predict total cost. However, he now realizes that the city/location of work variable (X5) might be more appropriately modeled by a collection of binary variables. Modify the data set to include the necessary binary variables. Because there are six distinct city/location values, five binary variables would be needed.

What is a Scatter plot?

A scatter plot is a type of data visualization that displays the relationship between two variables. It is created by plotting individual data points on a graph, with one variable represented on the x-axis and the other variable represented on the y-axis.

a) Each data point is represented by a dot on the graph, and the position of the dot corresponds to the values of the variables for that particular data point.

Scatter plot for total cost (Y) and regular/premium wages paid (X1): Relationship:  The scatter plot shows a positive linear relationship between total cost and regular/premium wages paid. As the wages paid increase, the total cost tends to increase as well.

Scatter plot for total cost (Y) and total units of work required (X2):

Relationship:  The scatter plot shows a positive linear relationship between total cost and total units of work required. As the total units of work increase, the total cost tends to increase as well.

Scatter plot for total cost (Y) and contracted units of work per day (X3):

Relationship:  The scatter plot shows a positive linear relationship between total cost and contracted units of work per day. As the contracted units of work per day increase, the total cost tends to increase as well.

Scatter plot for total cost (Y) and level of equipment required (X4):

Relationship:  The scatter plot does not show a clear linear relationship between total cost and the level of equipment required. The data points are scattered, indicating that other factors may influence the total cost apart from the level of equipment.

Scatter plot for total cost (Y) and city/location of work (X5):

Relationship:  The scatter plot does not show a clear linear relationship between total cost and city/location of work. The data points are scattered, suggesting that the city/location of work alone may not be a strong predictor of the total cost.

b.)  Based on the scatter plots and considering the relationship between the independent variables and the total cost, the estimator should consider using the combination of the following independent variables:

regular or premium wages paid (X1), total units of work required (X2), and contracted units of work per day (X3). The estimated regression equation for this model can be determined using regression analysis techniques.

c.) To modify the data set to include binary variables representing the city/location of work (X5), we need five binary variables since there are six distinct city/location values.

Let's assume the binary variables are represented as follows:

Binary variable X51: 1 if city/location is 1, 0 otherwise.

Binary variable X52: 1 if city/location is 2, 0 otherwise.

Binary variable X53: 1 if city/location is 3, 0 otherwise.

Binary variable X54: 1 if city/location is 4, 0 otherwise.

Binary variable X55: 1 if city/location is 5, 0 otherwise.

Binary variable X56: 1 if city/location is 6, 0 otherwise (all zeros).

d.) Based on the modified data set, the estimator should now consider using the combination of the following independent variables:

total units of work required (X2), binary variables X51, X52, X53, X54, and X55 representing the city/location of work. The estimated regression equation for this model can be determined using regression analysis techniques.

e.) To recommend the best regression model, we need to compare the adjusted R2 values of the models identified in parts b and d.

The adjusted R2 value provides a measure of how well the regression model fits the data while considering the number of independent variables.

The estimator should choose the model with the higher adjusted R2 value, as it indicates a better fit to the data. A higher adjusted R2 value implies that the selected independent variables explain a larger proportion of the total cost variation.

(Need help asap) Richie and Saul are conducting a survey on the most popular board games played by students at their high school. Richie interviews 25 boys from grades 9 through 12 and concludes that card games are the most popular among high school students. Saul speaks with 20 students, including girls and boys, from grades 9 through 12 and concludes that word games are the most popular among high school students. Whose generalization is valid? Why?

Answers

Answer: I’d say that Saul’s generalization is more valid because even though he interviewed less people, he interviewed girls as well as boys, and Richie only interviewed the boys.

Answer:Given that Saul spoke with both boys and females, his generalization is accurate

Step-by-step explanation:?A generalization is a kind of abstraction where the general traits of specific cases are articulated as overarching concepts or claims. Generalizations presuppose a domain or collection of elements, as well as one or more shared characteristics.Why is being general useful?Generalization is the capacity to do an action, engage in an activity, or display a behavior in a variety of situations, with a variety of people, and at a variety of times. Our ability to complete routine tasks in a variety of contexts and settings is due to the fact that we have "generalized" the necessary skills.
