40, because if you have 3 and 10 and 12 is 4 times 3. So you would multiply 10x4 to get 40.

The table represents an exponential function. What is the multiplicative rate of change of the function?

SOVA2 [1]

Answer:

0.5

Step-by-step explanation:

We find the multiplicative rate of change simply by taking one of the y values and dividing it by the y value right above it.

Here, let's just arbitrarily choose y = 0.125. We divide this by the y value above it, which is y = 0.25:

0.125 / 0.25 = 0.5

So, the multiplicative rate of change is 0.5.

Hope this helps!

A sample of 60 items from population 1 has a sample variance of 8 while a sample of 40 items from population 2 has a sample vari

lora16 [44]

Answer:

H0: $\sigma^2_1 = \sigma^2_2$

H1: $\sigma^2_1 \neq \sigma^2_2$

The statistic would be given by:

$F=\frac{s^2_2}{s^2_1}=\frac{10}{8}=1.25$

Step-by-step explanation:

Information given

$n_1 = 60$ represent the sample size 1

$n_2 =40$ represent the sample size 2

$s^2_1 = 8$ represent the sample variance 1

$s^2_2 = 10$ represent the sample variance 2

The statistic to check the hypothesis is given by:

$F=\frac{s^2_2}{s^2_1}$

Hypothesis to test

We want to test if the two variances are equal, so the system of hypothesis are:

H0: $\sigma^2_1 = \sigma^2_2$

H1: $\sigma^2_1 \neq \sigma^2_2$

The statistic would be given by:

$F=\frac{s^2_2}{s^2_1}=\frac{10}{8}=1.25$
