Answer:

y = 4 * (7/4) ^x

Step-by-step explanation:

y = ab^x is the general form of an exponential function

where a is the initial value and b is the growth rate

We know 2 points, (0,4) or the initial value and (1,7)

a =4

y = 4 b^x

7 = 4 b^1

We can solve for b

Divide by 4

7/4 = b

y = 4 * (7/4) ^x

Answer:

g(x) = 2x + 2

Step-by-step explanation:

f(x) = 6x

g(x)= 1/3*f(x) + 2

g(x) = 2x + 2

For a data set of brain volumes (cm3) and IQ scores of eight males, the linear correlation coefficient is found and the P-val

tatiyna

Answer:

The P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is 0.793 which is high so there is not sufficient evidence to conclude that there is a linear correlation between brain volume and IQ score in males.

Step-by-step explanation:

We are given the following information in the question:

p-value = 0.793

Significance level = 0.05

$H_{0}: \mu = \text{ The population correlation coefficient is not significantly different from 0}\\H_A: \mu = \text{ The population correlation coefficient is significantly different from 0}$

Since p value is greater than the significance value so we fail to reject the null hypothesis and accept the null hypothesis. We conclude that there is not a significant linear relationship between two variables.

Thus, we can write:
