The null hypothesis and the research hypothesis respectively refers to;

A: Population; Sample

Null hypothesis is defined as a working hypothesis making a claim about the population parameter in question. This means it deals with an overall Population.

Whereas, the alternative hypothesis also called the research hypothesis is one that seeks to disapprove or validate the null hypothesis and as such it is based on the results taken from a sample of a given population from which the null hypothesis is based.

Answer:

80

Step-by-step explanation:

I took the test

The measure of the fifth angle will be 80°. Then the correct option is B.

The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.

Let 'n' be the number of sides of the polygon. Then the sum of the interior angles of the polygon is given as,

Sum of angles = (n - 2) × 180°

The sum of the interior angle of the pentagon is given as,

Sum of angles = (5 - 2) × 180°

Sum of angles = 3 × 180°

Sum of angles = 540°

And the diagram is given below. The equation is given as,

x + 90° + 90° + 140° + 140° = 540°

x + 460° = 540°

x = 540° - 460°

x = 80°

The measure of the fifth angle will be 80°. Then the correct option is B.

Answer:

Approximately 8.234 inches.

Step-by-step explanation:

The area for a sphere is 4πr²

=> r² = 213 : 4 : π = approx. 16.95
=> r = sqrt (16.95) = approx. 4.117

=> d = 4.117 x 2 = approx. 8.234 inches

The time that Rudy finished the race was 11:10: 10 am.

The time that Teresa's group finished the race was 10:50:08 am.

The formula that can be used to determine the time is Time = distance / average speed

Teresa's group = 26.6 / 16 = 1.6625 = 1 hour 40 minutes 10 seconds = 11:10: 10 am

Rudy's group = 16.6 / 12.5 = 1.328 = 1 hour 20 minutes 8 seconds = 10:50:08 am

15,12$

3,5$ × 4,42meter =15,12

Answer:

12

Step-by-step explanation:

The numbers of choices for each of B, C, D are independent of the choices the predecessors have made. It is clear where the car's owners will sit, so all we have to care about is where we put the other people. There are 16−4=12 places left in the cars, so there are 12!

there are 37,747,920,000 ways the soccer team can be taken to the match.

Let's break down the problem step by step to calculate the number of ways the soccer team can be taken to the match:

Step 1: Select the drivers for the cars.

There are 4 cars, and the owners of the cars will be the drivers. We need to choose 4 drivers from the 16 people, and this can be done using combinations. The number of ways to choose 4 drivers out of 16 is denoted as C(16, 4), which can be calculated as follows:

C(16, 4) = 16! / (4! * (16-4)!)

C(16, 4) = 16! / (4! * 12!)

C(16, 4) = (16 * 15 * 14 * 13) / (4 * 3 * 2 * 1)

C(16, 4) = 1820

There are 1820 ways to select 4 drivers for the cars.

Step 2: Assign passengers to the cars.

After selecting the drivers, each driver will take 3 other players as passengers. Since there are 3 passengers for each driver, we can calculate the number of ways to assign passengers to the cars using combinations again.

Number of ways to assign passengers to one car = C(12, 3) = 12! / (3! * (12-3)!) = 12! / (3! * 9!) = 220.

Since there are 4 cars, the total number of ways to assign passengers to the cars is 220^4 = 20,736,000.

Step 3: Combine the driver selection and passenger assignment.

To find the total number of ways the soccer team can be taken to the match, we need to multiply the number of ways to select the drivers (1820) by the number of ways to assign passengers (20,736,000):

Total number of ways = 1820 * 20,736,000 = 37,747,920,000.

So, there are 37,747,920,000 ways the soccer team can be taken to the match.

Answer:

SO THIS IS PRODUCT LAW, IF BASES ARE SAME, WE JUST ADD THE EXPONENTS.

t^x×t²=t¹⁰

t^(2+x)=t¹⁰

2+x=10

x=10-2

x=8

verifying the answer

x=8

t⁸×t²=t¹⁰

8+2=10

10=10

hence correct.

The constant of proportionality is 6

Step-by-step explanation:

Recall the equation for direct variation is [tex]y=kx[/tex] where [tex]y[/tex] varies directly with [tex]x[/tex] and [tex]k[/tex] is the constant of proportionality. If we take any listed coordinate point, we can determine the value of [tex]k[/tex]. I will use (20,120) as an example:

[tex]y=kx\\\\120=k(20)\\\\6=k[/tex]

Therefore, the constant of proportionality is 6
