The correct decision in a hypothesis test when the data produces a t-statistic that is in the critical region is to reject the null hypothesis.

This is because a t-statics in the critical region indicates that the differences between the sample mean and the population mean are statistically significant. This means that the data indicates that the null hypothesis is wrong and that the alternative hypothesis is true. In a hypothesis test, the null hypothesis is what the researcher is trying to disprove. It is the general statement that suggests that there is no difference between the sample mean and the population mean. The alternative hypothesis is what the researcher is attempting to prove. It suggests that there is a difference between the sample mean and the population mean. Therefore, when the data produces a t-statistic that is in the critical region, it indicates that the alternative hypothesis is true. When a t-statistic is in the critical region, it means that the result is statistically significant. This means that the differences between the sample mean and the population mean are unlikely to have occurred by chance and that the alternative hypothesis is likely to be true. Therefore, when the data produces a t-statistic that is in the critical region, the correct decision is to reject the null hypothesis and accept the alternative hypothesis.

what's ir but looks like a calculator will help  

u need a little better explanation

Step-by-step explanation:

The program requires defining a function named 'laps_to_miles' that takes a number of laps as a parameter and returns the number of miles. Then, the program needs to call the function 'laps_to_miles' in the main program to calculate the number of miles and output the result.

To define the function 'laps_to_miles,' we can use the formula: miles = laps * 0.25, where laps is the number of laps entered by the user. Here's how we can define the function:

def laps_to_miles(user_laps):

   miles = user_laps * 0.25

   return miles

The function takes the user_laps as input, calculates the corresponding miles, and returns the miles value.

To call the function in the main program, we can take user input for the number of laps and pass it as an argument to the 'laps_to_miles' function. We can use the 'format' function to display the output with two digits after the decimal point. Here's the complete code:

def laps_to_miles(user_laps):

   miles = user_laps * 0.25

   return miles

# Main program

user_laps = float(input("Enter the number of laps: "))

miles = laps_to_miles(user_laps)

print("The number of miles is: {:.2f}".format(miles))

In the main program, we first take user input for the number of laps as a floating-point value. Then, we call the 'laps_to_miles' function with the user input as the argument, which returns the corresponding miles value. Finally, we use the 'format' function to display the miles value with two digits after the decimal point.

SA = surface area of rectangular prism

l = length

w = width

h = height

In the image, we are given the following information:

l = 4

w = 5

h = 3

Now, let's plug in the information given to us to solve for surface area:

SA = 2 ( wl + hl + hw)

SA = 2 ( 5(4) + 3(4) + 3(5) )

SA = 2 ( 20 + 12 + 15 )

Start at the point (0,-4) because the equation has -4 at the end. Then take the slope which is 1/4 you're gonna count up 1 then right 4. the next point will be (-3,4) and so on

The left-hand side is approximately equal to the right-hand side, the solution x ≈ 8.965 checks out.

To solve the equation x^((5)/(2)) = 32, we need to isolate x. Here's how we can do it:

Take the square root of both sides to get rid of the exponent:

√(x^((5)/(2))) = √(32)

Simplify the square root of x^((5)/(2)):

x^((5)/(4)) = √(32)

Simplify the square root of 32:

x^((5)/(4)) = √(2^5)

Since the square root of a number raised to a power is equal to the number raised to half of that power, we have:

x^((5)/(4)) = 2^((5)/(2))

Now, we can equate the exponents:

x^((5)/(4)) = (2^((1)/(2)))^5

Simplify 2^((1)/(2)):

x^((5)/(4)) = (√2)^5

Take the fifth power of (√2):

x^((5)/(4)) = 2^(5/2)

The equation becomes:

x^((5)/(4)) = 32

To get rid of the exponent (5/4), we can raise both sides of the equation to the reciprocal power (4/5):

(x^((5)/(4)))^((4)/(5)) = 32^((4)/(5))

Simplify the exponents:

x^1 = 32^((4)/(5))

We are left with:

x = 32^((4)/(5))

Now, we can evaluate x by calculating the right-hand side of the equation:

x = 32^((4)/(5))

x ≈ 8.965

Therefore, the solution to the equation x^((5)/(2)) = 32 is approximately x ≈ 8.965.

To check the solution, substitute x = 8.965 back into the original equation:

(8.965)^((5)/(2)) ≈ 32

Calculating the left-hand side:

(8.965)^((5)/(2)) ≈ 32.000 (rounded to three decimal places)

Step-by-step explanation:

The domain of a graph is all of the possible x values, and the range is all possible y values.

7. The graph goes on for both the x and y values, so the domain is (-inf, inf) and the range is (-inf, inf).

8. In this case, the domain is also (-inf, inf), but the range is [-2, inf) as there are no y values less than -2.

9. The domain is [-2, 2], as the x values only range from -2 to 2. The range is [-3, 3] as the y values range from -3 to 3.

10. The domain is (-inf, inf) because all x values are possible. The range is [-1, 1], as there are no y values greater than 1 or less than -1.

In mathematics, we can define ratio as how many times one number contains another. In the other word, a ratio says how much of one thing there is compared to another thing. Example, there are ten apples and six lemons in a basket of fruit, then the ratio of apples to lemons is ten to six (10:6). We can also say that the ratio of apples to the total amount of fruit is 10:16.

Answer:

r = \(\frac{1}{2}\) \(\sqrt{l^2+4h^2}\)

Step-by-step explanation:

h bisects l at right angles.

There is a right triangle formed with legs h and \(\frac{1}{2}\) l and hypotenuse r

Using Pythagoras' identity, then

r² = (\(\frac{1}{2}\) l )² + h²

   = \(\frac{1}{4}\) l² + h² ← factor out \(\frac{1}{4}\)

    = \(\frac{1}{4}\) (l² + 4h²)

Take the square root of both sides

r = \(\sqrt{\frac{1}{4}(l^2+4h^2) }\) = \(\frac{1}{2}\) \(\sqrt{l^2+4h^2}\)

Answer:

Step-by-step explanation:

Connect the endpoints of the with the center. The formed triangle is isosceles with sides l, r and r.

The height of the triangle h, is the distance between the center of the circle and the midpoint of the chord.

As per Pythagorean theorem we have:

The statement “there exists a function f such that f(x) < 0, f’(x) > 0, and f”(x) < 0 for all x” is false.

To understand why this statement is false, we must first understand what the symbols mean. The symbol f(x) refers to a function of x, and the symbols f’(x) and f”(x) refer to the first and second derivatives of the function, respectively.

The statement is saying that for all x, the function f(x) will be less than 0, the first derivative f’(x) will be greater than 0, and the second derivative f”(x) will be less than 0.

To show that this statement is false, we need to find an example of a function where this is not the case. Let’s consider the function f(x) = x³. At x = 0, this function is equal to 0, and so f(x) < 0 is not true. Additionally, the first derivative at x = 0 is f’(0) = 0, which is not greater than 0. Thus, the statement is false.

We can also show that this statement is false by looking at the graph of the function f(x). A function with the properties given in the statement would have a graph that looks like a “U” shape, with a minimum point at the origin. However, this is not the case for the function f(x) = x³. The graph of this function is a parabola, which does not have the desired shape.

Answer:

34 PERCENT

Step-by-step explanation:

To describe the stride lengths of ostriches in terms of the mean and standard deviation only, we can use the empirical rule (also known as the 68-95-99.7 rule). According to this rule, for a normal distribution:

- Approximately 68% of the data falls within one standard deviation of the mean.

- Approximately 95% of the data falls within two standard deviations of the mean.

- Approximately 99.7% of the data falls within three standard deviations of the mean.

Since the mean stride length of ostriches is 4.5 meters and the standard deviation is 0.75 meters, a stride length between 4.5 and 5.25 meters is within one standard deviation above the mean. Therefore, approximately 34% of the ostriches have stride lengths between 4.5 and 5.25 meters.

To find a similar percentage of emus, we can use the same approach. Since the mean stride length of emus is 3 meters and the standard deviation is 0.5 meters, we need to find the interval that is one standard deviation above the mean. This interval is from 3.5 meters to 2.5 meters, so approximately 34% of the emus have stride lengths between 2.5 and 3.5 meters.

To see this percentage using a graph of the normal curve, we can draw the curve for the distribution of ostrich stride lengths with mean 4.5 meters and standard deviation 0.75 meters. The area under the curve between 4.5 and 5.25 meters represents the percentage of ostriches with stride lengths in that range, which is approximately 34%. Similarly, we can draw the curve for the distribution of emu stride lengths with mean 3 meters and standard deviation 0.5 meters. The area under the curve between 2.5 and 3.5 meters represents the percentage of emus with stride lengths in that range, which is also approximately 34%.

Sorry if I got it wrong for you

Where the above conditions are given,  the correct option is: Plan 1 is a better deal for more than 5 cards purchased.

To determine   which pricing plan is a better deal,we need to compare the total cost for a certain number of game cards purchased.

Let's calculate the   total cost for different numbers  of game cards.

For Plan 1  -

- Admission fee  - $5 (fixed)

- Cost per game card  - $1

For Plan 2  -

- Admission fee  - $2.50 (fixed)

- Cost per game card  - $1.50

Now, let's compare the total cost for different numbers of game cards  -

1. If you purchase 1 game card  -

  - Plan 1  - $5 (admission fee) + $1 (cost per game card) = $6

  - Plan 2  - $2.50 (admission fee) + $1.50 (cost per game card) = $4

2. If you purchase 5 game cards  -

  - Plan 1  - $5 (admission fee) + $5 (cost for 5 game cards) = $10

  - Plan 2  - $2.50 (admission fee) + $7.50 (cost for 5 game cards) = $10

3. If you purchase 8 game cards  -

  - Plan 1  - $5 (admission fee) + $8 (cost for 8 game cards) = $13

  - Plan 2  - $2.50 (admission fee) + $12 (cost for 8 game cards) = $14.50

Based on these calculations, we can conclude that  -

- Plan 1 is a better deal for more than 5 cards purchased.

- Plan 2 is a better deal for more than 8 cards purchased.

Therefore, the correct option is  - Plan 1 is a better deal for more than 5 cards purchased.

The characters can be chosen from the word "AIME" or the number "2007".

There are 7 different characters that can be picked, with 0 being the only number that can be repeated twice.

There are two possible cases.

The first case is given below :

If 0 appears 0 or 1 time in the sequence, the number of possible sequences is 7!/(7-5)!.

If 0 appears 0 or 1 time in the sequence, the number of possible sequences is 2520.

The second case is given below :

If 0 appears twice in the sequence, the number of places to fill 0 is 5C2.

If 0 appears twice in the sequence, the number of places to fill 0 is 10.

The number of ways to place the remaining three characters is 6!/(6-3)!.

The number of ways to place the remaining three characters is 120.

The total number of ways in the second case is 10*120 = 1200.

The total number of ways is 2520 + 1200.

The total number of ways is 3720.

First simplify each mixed fraction into improper fraction, we get

\(((x\div \dfrac32)+\dfrac52)\times\dfrac53-\dfrac53=\dfrac{17}6\\\\\text{Now, }((x\div \dfrac32)+\dfrac52)\times\dfrac53=\dfrac{17}{6}+\dfrac53\\\\\Rightarrow\ ((x\div \dfrac32)+\dfrac52)\times\dfrac53=\dfrac92\\\\\Rightarrow\ ((x\div \dfrac32)+\dfrac52)=\dfrac92\times\dfrac35\\\\\Rightarrow\ ((x\div \dfrac32)+\dfrac52)=\dfrac{27}{10}\\\\\Rightarrow\ (x\div \dfrac32)=\dfrac{27}{10}-\dfrac52\\\\\Rightarrow\ (x\div \dfrac32)=\dfrac2{10}\\\\\Rightarrow\ x=\dfrac2{10}\times\dfrac32\\\\\Rightarrow\ x=\dfrac3{10}\)

Hence, the number is \(\dfrac3{10}\) or 0.3.

The solutions of the quadratic equation are given by x = (29 ± √825) / 4 which are two complex numbers.

What is a quadratic equation?

A quadratic equation is a type of polynomial equation that has the form of ax^2 + bx + c = 0, where x is the variable, and a, b, and c are coefficients. The general form of a quadratic equation is ax^2 + bx + c = 0, where a, b and c are constants. The solutions of a quadratic equation are given by the quadratic formula: x = (-b ± √(b^2-4ac)) / 2a

To solve for x in the equation 2x^2 -19x + 2 = -10x, we need to rearrange it in the standard form of a quadratic equation by isolating the x^2 term and moving the other terms to the other side:

2x^2 -10x -19x +2 = 0

2x^2 -29x +2 = 0

Now we can apply the quadratic formula:

x = (-b ± √(b^2-4ac)) / 2a

x = (-(-29) ± √((-29)^2-422)) / 2*2

x = (29 ± √(841-16)) / 4

x = (29 ± √(825)) / 4

Hence, the solutions of the quadratic equation are given by x = (29 ± √825) / 4 which are two complex numbers.
