Answer: x
<u>Step-by-step explanation:</u>
g(x) = 4x + 10 f(x) =
to find g(f(x)), replace "x" in the g(x) equation with what f(x) equals. Another way of writing g(f(x)) for this problem is: g(
).
g(f(x)) = 4
+ 10
= x - 10 + 10
= x
Yes, the correlation coefficient is statistically significance
The precise metric used in a correlation analysis to quantify the strength of the linear relationship between two variables is the correlation coefficient. In a correlation report, the r stands for the coefficient.
Given,
Sample size, n = 4
Where ρ is the population correlation.
Then the number of degrees of freedom is, df = n-2 = 4-2 = 2
The corresponding critical correlation value re for a significance level of a 0.01, for a two-tailed test is た= 0.254
Here,
The null hypothesis,
= ρ - 0 is rejected
Suppose lr> re 0.254
Because on the sample correlation provided, we know that lrl = 0.835>=0.254.
Here, it is clear that the null hypothesis is rejected.

Answer:
23.88528
Step-by-step explanation:
since x =19
substitute the value of of x in the equation
y=1.06915(19) + 3.57143
y=20.31385 + 3.57143
y= 23.88528
If base is x
congruent side = 2x-8
perimeter=2 congruent sides +base
2(2x-8)+x=74
4x-16+x=74
5x=58
x=11.6
length of the base is 11.6 inches
Answer:
70 miles
Step-by-step explanation:
If you work 7 miles from your home, we must consider that it would take double the amount of miles to get to work and back home.
So do the following,
- Multiply 7 x 2 to represent the total amount of miles you must ride to get to and from work.
7 x 2 = Y
- Then, multiply the product by 5 to represent the 5 days you go to work.
Y x 5= A
Work:
7 x 2 = 14
14 x 5 = 70
Y= 14 X= 70
