Answer:
$195311
Step-by-step explanation:
Given the expression yˆ=20646*0.86x
Given that the number years 11
And x represent the number of years
Substituting x=11 in the expression for the cost we have
yˆ=20646*0.86(11)
yˆ=20646*9.46
yˆ=20646*9.46
yˆ=195311.16
From the analysis he purchased the car fro $195311
Answer:
A one-sided, two-sample t-test
Step-by-step explanation:
In the context, the values of the population standard deviations are not provided, therefore we have to use the two sample t tests for the difference between the two population means. This claim for the hypothesis or the alternative hypothesis is given as the average selling price is more for the first group of the sample size of 21 as compared to the other group of the sample size of 87. Therefore, we perform an one sided test or the upper tailed test.
Answer:
Your answer will be
y=2x-15.5
Step-by-step explanation:
Hi, there you must know the slope-intercept form which is
y=mx+b
m=slope
b=y-intercept
You can also use
the slope formula which is

in this case
it will look like this
=
=-2
So the slope is -2
Now we will find the y-intercept
-7.5=2(4)+b
-7.5=8+b Subtract 8 both sides
-15.5=b
Your y-intercept is -15.5
Hope this helps
