What predicted vehicle weight would indicate a vehicle whose gas mileage is 30 miles per gallon?(1 point)5. Suppose you have a vehicle that weighs 1500 pounds. Use the model to determine the expected city MPGof the vehicle. (1 point)
Answers
Given the values shown in the table, let be "x" the Vehicle weight (in hundreds of lbs.) and "y" the City MPG (Miles per gallon).
1. Given the points:
\((27,25),(35,19),(39,16),(32,21),(40,15),(23,29),(18,31),(37,15),(17,46),(23,26),(37,17),(30,26),(23,29),(32,19),(20,33),(30,21)\)You can plot them on a Coordinate Plane:
2. Notice the following line:
Notice that the points are closed to the red line that has a negative slope. Therefore, you can identify that when one of the variables increases, the other variable decreases. Hence, you can conclude that the data describes a negative correlation.
3. You need to follow these steps to find the equation of the line of best fit:
- You need to find the average of the x-values by adding them and dividing the Sum by the number of x-values:
\(\bar{X}=\frac{27+35+39+32+40+23+18+37+17+23+37+30+23+32+20+30}{16}\)\(\bar{X}=28.9375\)- Find the average of the y-values:
\(\bar{Y}=\frac{25+19+16+21+15+29+31+15+46+26+17+26+29+19+33+21}{16}\)\(\bar{Y}=24.25\)- Find:
\(\sum_{i=1}^n(x_i-\bar{X})\)Where this represents each x-values in the data set:
\(x_i\)You get:
\(\sum_{i=1}^n(x_i-\bar{X})=(27-28.9375)+(35-28.9375)+(39-28.9375)+(32-28.9375)+(40-28.9375)+(23-28.9375)+(18-28.9375)+(37-28.9375)+(17-28.9375)+(23-28.9375)+(37-28.9375)+(30-28.9375)+(23-28.9375)+(32-28.9375)+(20-28.9375)+(30-29.9375)\)\(\sum_{i=1}^n(x_i-\bar{X})=1.0625\)- Find:
\(\sum_{i=1}^n(x_i-\bar{Y})\)You get:
\(\sum_{i=1}^n(x_i-\bar{Y})=(25-24.25)+(19-24.25)+(16-24.25)+(21-24.25)+(15-24.25)+(29-24.25)+(31-24.25)+(15-24.25)+(46-24.25)+(26-24.25)+(17-24.25)+(26-24.25)+(29-24.25)+(19-24.25)+(33-24.25)+(21-24.25)\)\(\sum_{i=1}^n(x_i-\bar{Y})=-3.25\)- Find:
\(\sum_{i=1}^n(x_i-\bar{X})(y_i-\bar{Y})\)You get:
\(=-857.75\)- Find:
\(\sum_{i=1}^n(x_i-\bar{X})^2\)You can find it by squaring each Difference of the x-values and the Mean. you get:
\(=862.9375\)- Find the slope of the line
\(m=\frac{-857.75}{862.9375}\approx-0.994\)- Find the y-intercept with this formula:
\(b=\bar{Y}-m\bar{X}\)\(b=24.25-(-0.994)(1.0625)\)\(b=53.0135\)Therefore, the line in Slope-Intercept Form:
\(y=mx+b\)is the following:
\(y=-0.9940x+53.0135\)4. If:
\(y=30\)You can predict the vehicle weight by substituting that value into the equation found in Part 3, and solving for "x":
\(30=-0.9940x+53.0135\)\(\frac{30-53.0135}{-0.9949}=x\)\(x\approx23.1524\)5. If a vehicle weighs 1500 pounds, then:
\(x=1500\)Then you can determine the expected city MPG of the vehicle by substituting this value into the equation and evaluating:
\(y=-0.9940(1500)+53.0135\)\(y\approx-1437.9865\)Hence, the answers are:
1.
2. It describes a negative correlation.
3.
\(y=-0.9940x+53.0135\)4.
\(x\approx23.1524\text{ \lparen in hundreds of pounds\rparen}\)5.
\(y\approx-1437.9865\text{ \lparen In miles per gallon\rparen}\)

Answers
The value of the probability of hitting the target is 0.1736.
According to the statement
We have to find that the value of the probability.
So, For this purpose, we know that the
Probability is the branch of mathematics that studies the possible outcomes of given events together with the outcomes' relative likelihoods and distributions.
From the given information:
A circular dartboard with a diameter of 24 inches has a circular bullseye at its center. The diameter of the target is 10 inches.
Then
Area of a circular dartboard = \(\pi r^{2}\)
Area of a circular dartboard = \((3.14)* 12^{2}\)
Area of a circular dartboard = \((3.14) *144\)
Area of a circular dartboard = 452.16 inches
And then
Area of a circular bullseye = \(\pi r^{2}\)
Area of a circular bullseye = \((3.14)* 5^{2}\)
Area of a circular bullseye = \((3.14) * 25\)
Area of a circular bullseye = 78.5
Then
Probability of hitting the target = Area of a circular bullseye / Area of a circular dartboard
Probability of hitting the target = 78.5 / 452.16
Probability of hitting the target = 0.1736.
So, The value of the probability of hitting the target is 0.1736.

How many ounces of a 20% saline solution and how ounces of a 70% saline solution are needed to obtain 25 ounces that is a 50% saline solution?
Answers
Step-by-step explanation:
Let x be the number of ounces of 20% saline solution needed, and y be the number of ounces of 70% saline solution needed to obtain 25 ounces of a 50% saline solution.
To solve the problem, we can use the fact that the amount of salt in the final mixture must equal the sum of the amounts of salt in the two original solutions. That is:
0.2x + 0.7y = 0.5(25)
Simplifying this equation gives:
0.2x + 0.7y = 12.5
We also know that the total amount of solution is 25 ounces, so:
x + y = 25
We now have two equations with two variables, which we can solve using algebra. Rearranging the second equation to solve for x in terms of y, we get:
x = 25 - y
Substituting this expression for x into the first equation, we get:
0.2(25 - y) + 0.7y = 12.5
Multiplying out the terms and simplifying gives:
5 - 0.2y + 0.7y = 12.5
0.5y = 7.5
y = 15
Substituting this value for y into the equation x = 25 - y, we get:
x = 25 - 15 = 10
Therefore, we need 10 ounces of the 20% saline solution and 15 ounces of the 70% saline solution to obtain 25 ounces of a 50% saline solution.
Quinn needs to collect at least 90 toys for a toy drive to earn community service credit. He has already collected 16 toys.
Answers
Let's define the next variable:
t: number of toys that Quinn still needs to collect
The number of toys that he already collected plus the number of toys that Quinn still needs to collect is: 16 + t
Quinn needs to collect at least 90 toys, then 16 + t must be greater than or equal to 90, that is,
16 + t ≥ 90
or
90 ≤ 16 + t
Subtracting 16 at both sides, we get:

time return - time going = 1
36/x - 36/(x+18) = 1

36 ( x + 18 ) - 36 x = 1 x ( x + 18 )

Answers
3. The factored polynomial is p(x) = (x - 1)(x - 5)
4. The factored polynomial is p(x) = (x + 3)²
What is a polynomial?A polynomial is a mathematical expression in which the power of the unknown is greater than or equal to 2.
3. To factorize the polynomial using the graph, we see that the polynomial cuts the x - axis at x = 1 and x = 5.
This implies that its factors are (x - 1) and (x - 5)
So, the factored polynomial is p(x) = (x - 1)(x - 5)
4. To factorize the polynomial using the graph, we see that the polynomial touches the x - axis at only one point x = -3. So,it has repeated roots
This implies that its factors are (x - (-3)) = (x + 3) twice
