What is a function?A statement, principle, or policy that creates the link between two variables is known as a function.
Monthly private school tuition based on the average number of weeks in attendance is predicted using the least-square regression line.
y = 265.9 + 93.4x, where y represents the predicted monthly expense and x represents the average number of weeks in attendance.
A child attends private school an average of 3.5 weeks and has a monthly cost of $595.
Then the residual for the child will be
⇒ 595 – (265.9 + 93.4 × 3.5)
⇒ 595 – (592.8)
⇒ 2.2
Then the correct option is B.

Which expression best represents the value of *sign*
Answers
Answer:6.28
Step-by-step explanation:
Expression that best represents value of π is C/2r,
Value of π used to calculate circumference is 3.14
What is circle?A circle is a plane figure bounded by one curved line, and such that all straight lines drawn from a certain point within it to the bounding line, are equal. The bounding line is called its circumference and the point, its center.
Given,
Circumference of circle C = 53.38
Radius of circle r = 8.5
C = 2πr
π = C/2r
π = 53.38/2 × 8.5
π = 53.38/17
π = 3.14
Hence, value of π is 3.14 for calculating circumference of circle, which can be calculated with expression C/2r

A local orange grower processes 2,330 oranges from his grove this year. The oranges are packaged in crates that each holds 96 oranges. All but one crate is full. How many oranges are in the last crate?
Answers
Answer:
13
Step-by-step explanation:
Given parameters:
Number of oranges processed by grower = 2330 oranges
Number of oranges per crate = 96
Unknown:
Number unpacked oranges
Solution:
To solve this problem, divide the total number of oranges by the number of oranges per crate;
Number of unpacked oranges = [tex]\frac{2330}{96}[/tex]
Number of unpacked oranges = 24 [tex]\frac{13}{48}[/tex]
The remaining unpacked is 13.

Answer:
x = 17, y = 25.5
Step-by-step explanation:
Since ABC is congruent to DEF, we can say that angle A = D and B = E by CPCTC
So to find x we can do:
5x + 2 = 87
5x = 85
x=17
So x is 17
Since B = E and E is 42 degrees, then B must also be 42 degrees. So 87 , 42, and 2y must add up to 180 degrees because it is a triangle.
87 + 42 + 2y = 180 degrees
129 + 2y = 180
151 = 2y
y = 25.5
So x = 17 and y = 25.5

To find the zeros of a function, you have to set each factor to zero in equations, then solve for x ....
x + 10 = 0 ... then factor 10 over (subtract 10 from each side) ...
x = -10
x-5=0
then repeat (add 5 to both sides) (and subtract 1 from both sides) ...
x -5 = 0 to x = 5
