Answer:

Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.

Step-by-step explanation:

We use the central limit theorem to solve this question.

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a sample size larger than 30 can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$

Since the sample size is larger than 30, the cognitive psychologist can assume that the sampling distribution of M will be approximately normal.

Scientists are studying the temperature on a distant planet. They find that the surface temperature at one location is 40° Celsi

jok3333 [9.3K]

Answer:

T(h) = 20 - 3h

Step-by-step explanation:

We are told that for every km you go up, the temp goes down 3°.

Let's say you go up 1km, then the temp should be 17°. We can easily represent it by the equation: T(h) = 20 - 3h

If we go up 1km: T(1) = 20 - 3*(1) = 20 - 3 = 17°

If we go up 2km: T(2) = 20 - 3*(2) = 20 - 6 = 14°

If we go up 3km: T(3) = 20 - 3*(3) = 20 - 9 = 11°

3(x + 1) + 2 < 11<br> Solve each inequality and graph the solution

maxonik [38]

Answer:

3x+3+2<11

Step-by-step explanation:

3x<11+3+2

3x<16

so now you divide 3 by the co-efficient

3x/3<16/3

so now 3 council 3 then you get x

x<16/3

x<5

now x is equal to 5
