Make a decision about the given claim. Use only the rare event​ rule, and make subjective estimates to determine whether events

are likely. For​ example, if the claim is that a coin favors heads and sample results consist of 11 heads in 20​ flips, conclude that there is not sufficient evidence to support the claim that the coin favors heads​ (because it is easy to get 11 heads in 20 flips by chance with a fair​ coin). ​Claim: The mean respiration rate (in breaths per minute) of students in a large calculus class is greater than 15. A simple random sample of the students has a mean respiration rate of 29.5. Choose the correct answer below. A. The sample is unusual if the claim is true. The sample is not unusual if the claim is false.​ Therefore, there is sufficient evidence to support the claim. B. The sample is unusual if the claim is true. The sample is not unusual if the claim is false.​ Therefore, there is not sufficient evidence to support the claim. C. The sample is not unusual if the claim is true. The sample is unusual if the claim is false.​ Therefore, there is sufficient evidence to support the claim. D. The sample is not unusual if the claim is true. The sample is unusual if the claim is false.​ Therefore, there is not sufficient evidence to support the claim.

If y varies directly as x and y = 3 when x = - 9, then find x when y = 5.
Rus_ich [418]

Answer:

d. - 15

Step-by-step explanation:

The equation for direct variation is

y = kx

We know y =3 when x = -9

3 = k(-9)

Divide by -9

3/-9 = -9k/-9

-1/3 = k

The equation is then

y = -1/3 x

We know y = 5

5 = -1/3 x

Multiply each side by -3

-3*5 = -3*-1/3x

-15 = x
