We have that the conclusion Keisha make is
[tex]A+B=\frac{mp+(nq)}{qp}[/tex] from the options below
Therefore
Option C is correct
From the Question we are told that
m, n, p, and q are all integers
[tex]p \neq 0 q \neq 0\\\\\A=\frac{m}{q} B=\frac{ n}{p}[/tex]
Generally the equation for A.B is mathematically given as
[tex]A*B=\frac{m}{q}*\frac{n}{p}\\\\A*B=\frac{mn}{qp}[/tex]
Generally the equation for A.B is mathematically given as
[tex]A+B=\frac{m}{q}+\frac{n}{p}[/tex]
Finding LCM of the denominators and adding through we have
[tex]A+B=\frac{mp+(nq)}{qp}[/tex]
The conclusion Keisha make is
[tex]A+B=\frac{mp+(nq)}{qp}[/tex] from the options below
Therefore
Option C is correct

1. The snow pack on Mt. Hood in the Oregon Cascades was 150 inches on
January 15th. Based on data taken in previous years, the snow pack decreases
about 11 inches a week after January 15th. What would be the rate of change?
Answer:
The rate of change is 10%
Step-by-step explanation:
The computation of the rate of change is as follows:
Given that as on Jan 15, the snow pack is 150 inches
And, the last year, it would decrease by 11 inches a week after jan 15
So, the rate of change is
= 15 ÷ 150
= 10%

Answer:
A = 76
Step-by-step explanation:
Formula of the area of a triangle: [tex]A=\frac{h*b}{2}[/tex]
Formula of a rectangle: [tex]A=l*w[/tex]
So starting with the triangle...You know that the height of the triangle is 7, and the base of the triangle is 8 because the base of the rectangle is the same as the triangle's base...
Now using the formula of the triangle...
A = [tex]\frac{7*8}{2}[/tex]
= 28
Now find the area of the whole retangle...The length of the rectangle is 13 because 7+6=13; the width is 8
Now using the formula of the rectangle...
A = [tex]13*8[/tex]
= 108
Now that you have the areas of both the triangle and the retangle...Do subtraction to find the shaded area...
[tex]108 - 28 = 76[/tex]

B. Yes! Jason has printed 73/100 of the posters needed.
С. Yes! Jason has printed exactly 7/10 of the posters needed.
D. No! Jason has only printed 29/50 of the posters needed
Answer:
B. Yes! Jason has printed 73/100 of the posters needed.
Step-by-step explanation:

Answer:
1/7
Step-by-step explanation:
1/3 of 3/7 = 1/3 x 3/7
we can cancel out 3 and 3 because they are multipliers of themselves
so now it is 1/1 x 1/7 = 1/7
Or .
1/3 x 3/7 = 1x3/3x7 = 3/21 = 1/7

Answer:
35
Step-by-step explanation:
solve the equation please
=========================================================
Work Shown:
Let x = log(y+2)
The given equation becomes
4x = 3x-log(13)
Solving for x leads to
4x-3x = -log(13)
x = -log(13)
Then substituting gets us
log(y+2) = -log(13)
log(y+2) = log(13^(-1)) .... use the rule that A*log(B) = log(B^A)
log(y+2) = log(1/13)
y+2 = 1/13 ................. used the rule if log(A) = log(B), then A = B
y = (1/13) - 2
y = (1/13) - (26/13)
y = (1-26)/13
y = -25/13 .... answer is choice E
For each step, the logs are the same base. The base doesn't matter. It can be base 10 or base 2 or base e. As long as the base stays consistent is all that matters. Also, the base cannot be 1, 0 or a negative number. The base can be any other real number.

A polling organization uses random digit dialing of registered voters in a county to gauge the voters’ opinions about a ballot initiative to increase taxes that would pay for a new county park. The polling organization will investigate whether there are differences in how voters respond based on the highest level of education completed. The phone survey asked the voters contacted whether they approve or disapprove of the tax increase. The voters were also asked to indicate their highest level of education completed: high school, bachelor’s degree, or master’s degree. Which of the following is the appropriate test to investigate whether there is an association between opinion about the ballot initiative and highest level of education completed?
А. A two-sample t-test for a difference between means
