amy runs more on average.
both mean !
Answer:
Amy
Explanation:
Because add all of the numbers and divide by 7.
The measure of center I would use for Amy is 6 because it is higher than half of the numbers and lower than half of the numbers.What I would use for Chelsea is 7 because of the same reason.

Which function has a graph with a vertical
asymptote at x = 7 and a horizontal asymptote at
f(x) = -3?
Please help me
Answers
Answer:
[tex]f(x)=\frac{1}{x-7}-3[/tex], see the graph attached for a visual reference.
Step-by-step explanation:
Vertical asymptotes are only present in rational functions where the parent function [tex]f(x)=\frac{1}{x}[/tex] has a vertical asymptote at the line [tex]x=0[/tex] and a horizontal asymptote at the line [tex]y=0[/tex]. Because the vertical asymptote has to be [tex]x=7[/tex], the denominator must be x-7 in order for the denominator to equal 0. For the horizontal asymptote to be [tex]y=-3[/tex], then 3 must be subtracted from the rational function. Therefore, the function that has these asymptotes is [tex]f(x)=\frac{1}{x-7}-3[/tex].
To find the vertical asymptotes, set the denominator of f(x) equal to zero.
-3x - 3 = 0
-3x = 3
x = -1
The vertical asymptote is
x = -1
To find the horizontal asymptotes, we examine the degree of the numerator and denominator of f(x). We use the leading terms to determine the degree. The leading term in the numerator is 7x0. The leading term of the denominator is -3x1. Since the exponent of x in the numerator is 0, the degree is 0 . Since the exponent of x in the denominator is 1, the degree is 1. The degree in the numerator is less than the degree in the denominator. Therefore, the horizontal asymptote is
y = 0
This also indicates that there are no x-intercepts.
To find the y-intercepts, set x=0.
The y-intercept is (0, -7/3).
Assume a mats price from the start is "X" USD. Write an expression for what the mat would cost after being reduced by P % (unknown amount of percentage)
Answers
Answer:
Step-by-step explanation:
[tex]cost \ price = X\\Deduction = P \%\\Deduction \ Price = P \% of X = \frac{P}{100} \times X = \frac{XP}{100} \\\\Cost \ price \ after \ deduction = X -\frac{XP}{100}[/tex]
OR SIMPLIFY FURTHER
[tex]X - \frac{XP}{100} = X( 1 - \frac{P}{100} )[/tex]

Find the Mean:
Find the median
Find the Mode:
Answers
Answer:
Mean: 46 Median: 45 Mode: 45
Step-by-step explanation:
Mean: 41+45+39+56+48+45+42+34+47+62+35+58 = 552 then, 552/12 = 46
Median: Put numbers in order from least to greatest and cross one out on each side until you get to the middle number. 45 and 45 were the last two numbers to be crossed out, the middle of those would simply be 45!
Mode: 45 appears twice while the rest of the numbers only appeared once.
