Answer:
C. 10Step-by-step explanation:
let n1 be the degree of freedom of factor A
Let n2 be the degree of freedom of factor B
If there are 5 levels of factor A, then n1 = 5
If there are 7 levels of Factor B then n2 = 7
The interaction between the degrees of freedom is expressed using the formula;
df = (n1 - 1)+(n2 - 1)
df = n1 -1 + n2- 1
df = n1+n2 -2
Substitute n1 and n2 and get df
df = 5+7-2
df = 12-2
df = 10
Hence the interaction degree of freedom is 10
PLEASE HELP!!! A line y=mx+b passes through point (−4, 6) and is perpendicular to y=−12x+6.
What is the value of b?
Answer:
Improper fraction: 19/3
Mixed number: 6 1/3
Step-by-step explanation:
If these two lines are perpendicular, their slopes are negative reciprocals of each other. The line would be something like:
y = (1/12)x+b
So plug in the coordinate values.
6 = (1/12)(-4)+b
6 = (-1/3)+b
6 1/3 = b
(x + 4y) - (-8x + 3y)

Alexander spent a total of 12.5 hours on a science project for the Science Fair. His sister, Laura, spent 16.6 hours on a science project. How many more hours did Laura spend on her project than Alexander spent on his?
Answer:
4.1 I think
Step-by-step explanation:
I just subtracted in my head
Answer:
4.1 hours
Step-by-step explanation:
Laura spent 4.1 more hours on her project than Alexander spent on his. If we split each number into 2 parts (like this: 12.5 -> 12 and .5; 16.6 -> 16 and .6) then we can subtract 12 from 16 and .5 from .6 to get 4 and .1. we add those together to get 4.1

The length of a rectangle is four times its width. Its perimeter is no greater than 170 cm. Find the greatest possible dimensions of the rectangle.
Step-by-step explanation:
let the length be =L
the width is 4 × the length
so the width will be 4L
the formular for the perimeter of a rectangle is =2(L +W)
170=2(L +4L)
170=2(5L)
170=10L
17=L
so the width is 4 × the length
17×4
=68
L=17
W=68

You want a new sound system to go with your new television. If you saved $30 for the sound bar that had a 21% discount. What was the original price of the sound bar before the discount?
Answer:
$142.86
Step-by-step explanation:
In order to know the original price of the sound bar, it is best to write the problem above into a mathematical sentence first.
Given: $30 = the amount you were able to save
21% = the discount (this means that $30 is the 21% discount)
Let x be the original price of the sound bar.
The mathematical sentence is:
$30 is 21%(0.21) of x
x=[tex]\frac{30}{0.21}[/tex]
x= $142.857 or $142.86 (once rounded off to the nearest hundredths)
So, the original price of the sound bar before the discount is $142.86

The Graph Shifts 4 units up
Step-by-step explanation:
Okay so, when you add four to a graph in this manner we have to look at the equation as a whole. f(x)=mx+b + 4. By adding four we are changing the y-intercept and shifting it up four. This will cause the entire graph to shift upwards four spaces.
A local construction site has workers that are digging the foundation of a new building. They
can haul away 20 lbs every 3.4 minutes while working. If they work for a total of 403
minutes, how many grams of dirt have they taken away? Round to a whole number.
Answer:
The workers can take away 1,075,280 grams of dirt in 403 minutes.
Step-by-step explanation:
[tex]\frac{403}{3.4}*20 = 2,370.588[/tex] pounds in 403 minutes
1 pound = 453.592 grams
2,370.588 * 453.592 = 1,075,280 grams

For every left-handed person, there are about 4-right handed people. If there are 30 students in a class, predict the number of students who are right-handed.
Answer:
There are 24 right handed students
Step-by-step explanation:
This is a ratio question so it would be represented as 1:4.
First you would do 1 + 4 which is 5.
Then do 30 ÷ 5 which is 6.
Finally multiply 6 by 4 and 1.
So 6 × 4 × 1 is 24.
So there are 24 students who are right handed.
Hope this makes sense!

Out of 60 applicants to a university, 40 are from the East. If 20 applicants are to beselected at random, find the probability that:
a. 10 are from East.
b. Not more than 2 are from East.
Answer:
a. 40С10 * 20С10 / 60С20
b. 1 + (40)(20) + (40C2)(20C2) / 60С20
Step-by-step explanation:
Total number of application = 60
Total number of application from east = 40
Total number of application remaining = 20
Number of ways of selecting 20 applicant = 60C20 (Sample space)
a. Probability of 10 are from East.
= (10 from east) * (10 from remaining)
= 40С10 * 20С10 / 60С20
b. Probability of Not more than 2 are from East.
= P(x≤2)
= P(x=0) + P(X=1) + P(X=2)
= [40С0 * 20С20 / 60С20] + [40С1 * 20С19 / 60С20] + [40С2 * 20С18 / 60С20]
= 1 + (40)(20) + (40C2)(20C2) / 60С20
