Answer:
(2,-8) (0,-2)
Step-by-step explanation:
M= slope
B= y-intercept
-2 is the y-intercept (0,-2), plot those coordinates
-3x is the slope
- slope is -3/1
- top number depicts if you go up or down, (-) go down and (+) go up
- the bottom number you go to the right
So, from (0,-2) go down three and to the right one

Zander and Chloe were comparing the number of texts they send. Zander has already sent 38 texts and says he sends 28 texts per day. Chloe has sent 52 texts already and says she send 26 texts a day. After __ days, Zander and Chloe will have sent the same amount of texts. A. 5 days B. 6 days C. 7 days D. 9 days
Answers
Answer:
(C) 7
Step-by-step explanation:
We can create an equation here.
We know that Zander has 38 texts. He sends 28 texts per day.
Let us represent x as the number of days.
This can be represented as an expression, [tex]38+28x[/tex].
Same logic for Chloe.
52 texts already, 26 texts per day: [tex]52+26x[/tex]
If their texts are equal, both expression are equivalent to each other.
[tex]38+28x = 52+26x[/tex]
We can simplify this equation to get x on one side of it.
Subtract 38 from both sides:
[tex]28x = 14+26x[/tex]
Subtract 26x from both sides:
[tex]2x =14[/tex]
Divide both sides by 2:
[tex]x = 7[/tex]
So, Chloe and Zander will have sent the same amount of texts after 7 days.
Hope this helped!

Given that every fifteenth person in line will get a coupon for a free box of popcorn at the movies, what is the probability that you don’t get a coupon when you’re in line? Enter a fraction or round your answer to 4 decimal places, if necessary.
Answers
Answer:
We know that every 15th person gets a free box of popcorn.
This depends on order, but nobody knows what is his actual position, so we can assume that:
of 15 people, 1 will get a free box of popcorn.
Then the probability of getting free popcorn is:
1/15
And the negation, (the probability of not getting a free box) is:
1 - 1/15 = 14/15 = 0.93...
The probability of not getting a free box is, [tex]\frac{14}{15}[/tex]
Probability :Given that, from 15 people, 1 will get a free box of popcorn.
Then the probability of getting free popcorn is:
[tex]P(E)=\frac{1}{15}[/tex]
the probability of not getting a free box is,

Torque (or moment) is the measure of turning force or twist on an object. If a mechanic is applying 12 Newton centimeters of torque on a bolt how many pound inches would this be?
Answers
Answer:
1.0638
Step-by-step explanation:
Given the question:
If a mechanic is applying 12 Newton centimeters of torque on a bolt how many pound inches would this be?
Torque = 12 Newton centimeter
Torque which is the turning effect on an object :
1 Newton = 0.225 pound force
1 centimeter = 0.394 inch
Hence ;
1 Newton centimeter = (1 × 0.225 × 0.394) = 0.08865 pound inch
12 Newton centimeter is hence, equals :
(12 × 0.225 × 0.394) pound inch
= 1.0638 pound inch

Answers
Answer:
The answer is option CStep-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
Equation of original line is y = ⅔x + 1
Comparing with the general equation above
Slope = 2/3
Since the lines are parallel their slope are also the same
Slope of parallel line = 2/3
So the equation of the line using point
( 1,1) and slope 2/3 is

. What is the total number of digits
printed, if a book containing 150
pages is to be numbered from 1 to
150?
Answers
Solution :-
Total number of pages in the book = 150
Total number of one digit numbers = From 1 to 9
= 1*9
9 digits
Total number of two digit numbers = From 10 to 99
= 2*90
= 180 digits
Total number of three digit numbers = From 100 to 150
= 3*51
= 153 digits
Total number of digits printed in the book containing 150 pages
= Total number of one digit numbers + Total number of two digit numbers +
Total number of two digit numbers
= 9 + 180 + 153
= 342 Digits
Hence, total 342 digits are printed in the book which has 150 pages.

How do you do both questions?
Answers
1. We have all the information we need here to set up our 'least-squares regression equation.'
Given: r = 0.68, x = 260, y = 70, s₁ = 33, s₂ = 6, remember that the general equation for our least-squares line is in the form y = a + bx. The slope of the regression equation is the linear correlation coefficient multiplied by the standard deviation for x:
b = r(s₂ / s₁) = 0.68(6 / 33) = 0.12363...
Remember that the constant of the regression equation is the mean of y decreased by the product of the slope and the mean of x:
a = y - bx = 70 - 0.12363(260) = 37.8562
The equation of the least-squares regression line would then be y = 37.8562 + 0.12363x. We know that the Jane's previous score was 279, so if we plug that into our equation as 'x' we will receive Jane's final score. The set up will be y = 37.8562 + 0.12363(279) = 72.34897. Your solution for the first part is absolutely correct!
2. Actually the values of 'y' could have been much larger. r^2 = 0.4624, thus the proportion of y explained by x is only about 46%. It would negatively affect her final course grade.

Answer:
f⁻¹(7) = 1
Step-by-step explanation:
Step 1: Write out function
f(x) = 3x + 4
Step 2: Find f⁻¹(x) (or known as inverse f(x))
y = 3x + 4
x = 3y + 4
-3y + x = 4
-3y = 4 - x
y = -4/3 + x/3
Step 3: Plug in 7 into inverse f(x)
f⁻¹(7) = 7/3 - 4/3
f⁻¹(7) = 3/3
f⁻¹(7) = 1

Nancy decides to roll a dice three times. What is the probability that she will roll all even numbers?
Answers
Given:
Nancy decides to roll a dice three times.
To find:
The probability that she will roll all even numbers.
Solution:
If a dice is rolled, then the possible numbers are
Total number = {1,2,3,4,5,6} = 6
Even numbers = {2,4,6} = 3
Odd numbers = {1,3,5} = 3
Probability of getting an even number [tex]=\dfrac{\text{Even number}}{\text{Total numbers}}[/tex]
[tex]P(\text{Even})=\dfrac{3}{6}[/tex]
[tex]P(\text{Even})=\dfrac{1}{2}[/tex]
So, probability of getting all even numbers is
[tex]P(\text{All even})=P(\text{Even})\times P(\text{Even})\times P(\text{Even})[/tex]
[tex]P(\text{All even})=\dfrac{1}{2}\times \dfrac{1}{2}\times \dfrac{1}{2}[/tex]
[tex]P(\text{All even})=\dfrac{1}{8}[/tex]
Therefore, the required probability is [tex]P(\text{All even})=\dfrac{1}{8}[/tex].
The probability that Nancy will roll all even numbers will be:
"[tex]\frac{1}{8}[/tex]".
ProbabilityAccording to the question,
Number of times dice rolled = 3
Total numbers = {1, 2, 3, 4, 5, 6}
= 3
Even numbers = {2, 4, 6}
= 3
Odd numbers = {1, 3, 5}
= 3
Now,
The probability of getting even numbers will be:
= [tex]\frac{Even \ numbers}{Total \ numbers}[/tex]
= [tex]\frac{3}{6}[/tex]
= [tex]\frac{1}{2}[/tex]
hence,
The required probability be:
= P(Even) × P(Even) × P(Even)
= [tex]\frac{1}{2}\times \frac{1}{2}\times \frac{1}{2}[/tex]
= [tex]\frac{1}{8}[/tex]
Thus the above answer is correct.

If 1 gallon of paint covers 300 square feet, how many gallons
are needed for a room 30' long x 20' wide x 12' high?
Answers
To cover the room of given dimensions 4 gallons of paint is needed.
What is an Area?The area of a two-dimensional figure is defined as the amount of space covered by the shape in a two-dimensional plane.
Given that 1 gallon of paint covers 300 square feet, there is a room of dimensions 30' long x 20' wide x 12' high
Surface area of room = 2(l+b)*h
= 2(30+20)*12
= 1200 in²
1 gallon for 300 in², therefore 1200/300 =4 gallons for 1200 in²
Hence, To cover the room of given dimensions 4 gallons of paint is needed.
