What is regression analysis?Regression analysis is a group of statistical procedures used in statistical modeling to determine the relationships between a dependent variable and one or more independent variables.
A scatter plot is a particular kind of plot or mathematical diagram that displays values for typically two variables for a collection of data. It uses Cartesian coordinates. When the points are coded, a further variable can be seen.
Given that store recorded the number of sweatshirts sold on several days throughout the year. The scatterplot shows the relationship between the average daily temperature and the number of sweatshirts sold.
Here is the scatter plot, it is observed that by increasing the temperature the number of sweatshirts sold is decreasing. For every 10-degree depression of temperature, the number of the sells is decreased by 50.
Therefore, for every 10-degree increase in temperature, the store sells around 50 fewer sweatshirts. The correct option is D.

One year Hank had the lowest ERA (earned-run average, mean number of runs yielded per nine innings pitched) of any male pitcher at his school, with an ERA of
3.05. Also, Sally had the lowest ERA of any female pitcher at the school with an ERA of 2.96. For the males, the mean ERA was 3.848 and the standard deviation was
0.742. For the females, the mean ERA was 5.007 and the standard deviation was 0.722. Find their respective Z-scores. Which player had the better year relative to
their peers, Hank or Sally? (Note: In general, the lower the ERA, the better the pitcher.)

Find equations of the spheres with center(1, −1, 6)that touch the following planes.a) xy-planeb) yz-planec) xz-plane
Answers
Given :
Center of sphere , C( 1 , -1 , 6 ) .
To Find :
Find equations of the spheres with center (1, −1, 6) that touch the following planes.a) xy-plane b) yz-plane c) xz-plane .
Solution :
a)
Distance of the point from xy-plane is :
d = 6 units .
So , equation of circle with center C and radius 6 units is :
[tex](x-1)^2+(y-(-1))^2+(z-6)^2=6^2\\\\(x-1)^2+(y+1)^2+(z-6)^2=36[/tex]
b)
Distance of point from yz-plane is :
d = 1 unit .
So , equation of circle with center C and radius 1 units is :
[tex](x-1)^2+(x+1)^2+(z-6)^2=1^2\\\\(x-1)^2+(x+1)^2+(z-6)^2=1[/tex]
c)
Distance of point from xz-plane is :
d = 1 unit .
So , equation of circle with center C and radius 1 units is :
[tex](x-1)^2+(x+1)^2+(z-6)^2=1^2\\\\(x-1)^2+(x+1)^2+(z-6)^2=1[/tex]
Hence , this is the required solution .

Solve for x: 3x+2=11
Answers
Answer:
X= 3
Step-by-step explanation:
To solve this, you must first subtract 2 from 11, to get the 3x isolated.
You'll then have 3x=9, but the x is not alone, so you subtract the 3 from both sides. This leaves you with 3
the value of x will be 3 for the given function 3x+2=11.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
Given a function 3x+2=11
Simplifying the function:
=> 3x + 2 = 11
subtract by 2
=> 3x +2 - 2 = 11-2
=> 3x = 9
divide by 3 into both sides
=> x = 3
Therefore, the value of x will be 3 for the given function.

Angel took a 2-year lease on a new car and after 4 months of driving, he’d put 5,600 miles on it. The lease allows 10,000 miles per year. If his driving habits stay consistent, will he stay under the allotted mileage for years? By how much?
Answers
Answer:
Step-by-step explanation:
Lease years = 2 years
Allowed mileage per year = 10,000 miles
After 4 months of driving ; 5600 miles on car
If driving habit stays consistent, Angel won't stay under the alloted mileage for years,
If 4 months = 5600 miles
Average miles driven per month :
5600 / 4 = 1400 miles / month
After two years ; ( 2 × 12) = 24 months
Total miles driven :
1400 miles × 24 = 33600 miles
Total alloted miles for 2 years:
10,000 × 2 = 20,000 Miles
Excess miles driven;
20,000

The tree was 60 inches tall to use later it was 105 inches tall what is the percentage increase to the nearest hundredth of the height of the tree
Answers
Answer:
[tex]\%\ increase = 75\%[/tex]
Step-by-step explanation:
Initial Height = 60 inches
Final Height = 105 inches
Required
Determine the percentage increase
Percentage increase is calculated as thus;
[tex]\%\ increase = \frac{Final\ Height - Initial\ Height}{Initial\ Height}[/tex]
Substitute values for the final and the initial height
[tex]\%\ increase = \frac{105 - 60}{60}[/tex]
[tex]\%\ increase = \frac{45}{60}[/tex]
[tex]\%\ increase = 0.75[/tex]
Convert to percentage
[tex]\%\ increase = 75\%[/tex]
The height of the tree increased by 75%.
Given that the tree was 60 inches tall, and later it was 105 inches tall, to determine what is the percentage increase to the nearest hundredth of the height of the tree, the following cross multiplication must be performed:
60 = 100 105 = X 105 x 100/60 = X 10500/60 = X 175 = X 175 - 100 = 75Therefore, the height of the tree increased by 75%.
