Hope this may helps you
Answer:
Column A:
You calculate slope doing y2-y1/x2-x1
So -10-1/5-(-2)= -11/7
Column B:
Rearrange the equation to get y
-3x+2y=7
2y=3x+7
y= 1.5x + 7
Therfore we have that the slope of column be is greater because it has a positive regression. While column A has a negative slope.

In ΔDEF, the measure of ∠F=90°, the measure of ∠D=66°, and EF = 32 feet. Find the length of FD to the nearest tenth of a foot.
Answers
Answer:
14.3
Step-by-step explanation:
Remark
Make a rough sketch of the triangle.
Make F the right angle
Make <D = 66
E is the other angle.
Givens
EF = 32
<F = 90
<D = 66
Equation
Tan(D) = EF/FD
Solution
Tan(66) = 32/FD Multiply both sides by FD
FD*Tan(66) = 32
Tan(66) = 2.246
2.246 * FD = 32 Divide by 2.2246
FD = 32/2.246
FD = 14.25
FD = 14.3
The average number of people who attended football games at a stadium increased from 8,000 people in the year 2005 to 12,500 in the year 2012. By what percentage did the average number of people at the games increase from 2005 to 2012?
Answers
56.1% is the average number of people at the games increase from 2005 to 2012
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
The average number of people who attended football games at a stadium in 2005 is 8000.
The average number of people who attended football games at a stadium in 2012 is 12500.
The difference from average number of people from 2005 to 2012
12500-8000
Twelve thousand five hundred minus eight thousand
4500
To find the percentage of increase we need to divide change in number by original number
4500/8000
0.561
Now multiply with 100 because it is a hundredth part.
0.561×100=56.1
Hence 56.1% is the average number of people at the games increase from 2005 to 2012

6 pounds of apples and 3 pounds of oranges cost 24 dollars.5 pounds of apples and 4 pounds of oranges cost 23 dollars. Set up a system of equations and solve to find out the cost for each pound of apples and each pound of oranges.
Answers
Answer:cost of each pound of apple= $3
And cost of each pound of orange =$2
Step-by-step explanation:
Step 1
Let cost of apples = x
And cost of Oranges =y
Let 6 pounds of apples and 3 pounds of oranges cost 24 dollars be represented as
6 x + 3y= 24----- equation 1
Also, Let 5 pounds of apples and 4 pounds of oranges cost 23 dollars be represented as
5x+ 4y= 23----- equation 2
Step 2
6 x + 3y= 24----- equation 1
5x+ 4y= 23----- equation 2
Using substitution method to solve the equation
6 x + 3y= 24
24-6x=3y
y= 24-6x/3 = 8-2x
Y= 8-2x
Substituting the value of y= 8-2x into equation 2
5x+ 4( 8-2x)= 23
5x+ 32 -8x= 23
32-23= 8x-5x
9=3x
x=9/3
x=3
Putting the value of x= 3 in equation 1 and solving to find y
6 x + 3y= 24
6(3) +3y= 24
18+3y=24
3y= 24-18
3y=6
y=6/3= 2
Therefore the cost of each pound of apple= $3
And cost of each pound of orange =$2

then we know all the angles in a triangle add up to 180 also
so we can do 64 + (2x + 4) + (3x - 13) = 180

Step-by-step explanation:
Percentages
The Medinas went out to eat at Chilli's and the bill was $65.20. They tipped 15% to their server.
This percentage is calculated over the amount of the $65.20 bill, thus the tip was:

The Medinas left $9.78 for a tip
Mindy bought 1¾ pounds of candy for herself and for each of three friends while she was at the candy store. How many pounds of candy did she buy?
Answers
Answer:
Mindy bought 7 pounds of candy.
Step-by-step explanation:
In order to solve this question we need to understand that based on the question itself there is 4 people (Mindy and the three friends) that each have [tex]1\frac{3}{4}[/tex] pound of candy. Now if you image in that way you see that in order to understand how much pounds of candy Mindy bought you will have to multiply [tex]1\frac{3}{4}[/tex] by 4 (because there is 4 people who got [tex]1\frac{3}{4}[/tex] pounds of candy each).
So now we can find the answer by doing the following.....
[tex](1\frac{3}{4} )(4) = ( \frac{7}{4})(\frac{4}{1}) = \frac{(7)(4)}{(4)(1)} = \frac{28}{4} = 7[/tex]

What is the difference between the exact amount and the estimated amount of medicine? d. How many grams are in one dose of medicine? Explain your strategy for solving.
Answers
Answer:
A. 29.93 grams
B. 29.925 grams
C. 0.005 grams
D. 5.985 grams per dose
Step-by-step explanation:
Chemical A = 10.357 grams
Chemical B = 12.062 grams
Chemical C = 7.506 grams
Number of doses of drugs = 5
A. About how much medicine in grams
Round each chemical to the nearest tenth
Chemical A = 10.36 grams
Chemical B = 12.06 grams
Chemical C = 7.51 grams
Total medicine in grams = chemical A + chemical B + chemical C
= 10.36 + 12.06 + 7.51
= 29.93 grams
B. Find the exact amount of medicine mixed by Dr. Stevens.
Total medicine in grams = chemical A + chemical B + chemical C
= 10.357 + 12.062 + 7.506
= 29.925 grams
C. What is the difference between the exact amount and the estimated amount of medicine
Difference = Estimated amount - Exact amount
= 29.93 grams - 29.925 grams
= 0.005 grams
D. How many grams are in one dose of medicine?
Grams in a dose = exact amount of chemicals / 5 doses
= 29.925 grams / 5
= 5.985 grams per dose
Approximately 5.99 grams per dose
