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]

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.

I hope this helped, good luck! :)

Same the it mean is 45,median is ,47,and mode it is 34

Explain how to decompose a triangle into congruent triangles. How does the area of those decomposed triangles relate to the area of the rectangle?

Answers

So for any triangle, you can divide it into four congruent triangles by connecting the midpoints of each side. You would divide the rectangle into half, to form two congruent triangles. When you multiply the area of 1 of the triangles, it gives you the area of both triangles, and so the area of the triangle as a whole.

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].

f(x) = 3 / (-3x - 3)

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).
