Find the slope of the line that goes through the points (-15,70) and (5,10) and (2,7) and (6,3).


Answer 1


Rise/run = 10-7/5-2 = 3/3 = 1

Therefore, the slope of the line is 1.

1.1. Kalvin always has cereal for breakfast. He likes Cocoa Blast cereal, but his mother wants him to eat Heath Nut Flakes at least some mornings.Kalvin and his mother agree to leave the cereal problem to chance. Each morning Kalvin tosses a coin. If the coin lands on heads, he will have Cocoa Blast. If the coin lands on tails, he will have Heath Nut Flakes. 1.2. Kalvin wants to find something else to toss that will give him a better chance of eating his favorite cereal each morning. He wonders if a paper cup would be a good thing to toss. Because Kalvin wants to eat Cocoa Blast more of the time, he needs to determine if the cup lands in one position more often than another. If so, he will ask to toss a paper cup instead of a coin. 1. Kalvin tosses a paper cup once a day for a year to determine his breakfast cereal. Use your results from problem 1.2 to determine the following. a. How many times do you expect the cup to land on its side? On one of its ends? b. How many times do you expect Kalvin to eat Cocoa Blast in a month? In a year? Explain. The cup lands on its side 80%(0.8) of the time, while it lands on its edges 20%(0.2) of the time, Heads on a coin would be equal to the cup landing on its side, and landing on its edges would be equal to a coin landing on tails.

Suppose you have a wallet with $5 bills, $10 bills, and $20 bills. If the probability of picking a $20 bill is 4/15, and the probability of picking a $20 bill is 4/15, and the probability of picking a $5 bill is 1/3, what is the probability of picking a $20 bill?


The question does not make any sense. The probability of a 20 bill has already been given.

$5 bills
$10 bills
$20 bills

probability of $20 is 4/15
probability of $5 is 1/3

numerator is the number of events
denominator is the number of outcomes

the missing probability is of the $10 bill.

4/15 + 1/3 + x = 1 or 15/15

$5 bill = 1/3 x 5/5 = 5/15

15/15 - 4/15 - 5/15 = (15-4-5)/15 = (15-9)/15 = 6/15 = 2/5

the probability of $10 is 2/5


The problem isn't copied out correctly. the first $20 should be $10

Step-by-step explanation:

Solve z-5 /7 = -1 z=?


(z - 5)/(7) = -1

times both sides by 7 (to get rid of the 7 on the left)

z - 5 = -7

Add 5 to both sides

z = -7 + 5 = -2

Factor completely x2 − 12x + 36.





(x -6) (x -6) or (x -6)^2

Step-by-step explanation:

Given :     x^2 − 12x + 36

since the leading coefficent for this equation is 1, we take 36 and find 2 factors that 36 has, and also adds up to -12. That would be  -6, and -6 because -6 + -6 = -12 AND -6 x -6 = 36 , therefore -6 and -6 are the numbers we are looking for. Which makes this the anwer:

(x -6) (x -6) or (x -6)^2

The quotient of a number and ten increased by five


x/10+5 because it says the quotient which means dividee'd by and a number I use x and then increased by 5 means +5 Hope this helps!=)
"quotient" = answer to a division problem
"increased by" = indicates the operation of addition

Let's allow the variable "n" represent the number. Since we are looking for the quotient of a number and 10, this means we must divide n by 10. Since we are increasing the answer of this expression by 5, we must add 5.


3/5 =2/3t what is t PLZ HELP


3/5 = (2/3)t
cross multiply
9/10 = t
2/3t = 3/5

Divide (inverse operation)

2/3t/2/3 = 3/5 divided by 2/3

3/5 * 3/2 = 9/10

t = 9/10

Answer: t = 9/10

6. Use the graph that shows the percent of cat ownerswho train their cats in each category. (Examples 3 and 4)a. Out of 255 cat owners, predict how manyowners trained their cat not to climb onfurniture.b, out of 316 cat owners, predict how many catowners trained their cat not to claw on furniture.Climbing onFurnitureClawingO FurnitureFightingwith otherAnimalsTraining Cats43%29%17%10 2030 40 50Percent Quick please


Answer: a) 110 b) 92

Step-by-step explanation:

Since we have given that

Percentage of animals not to climbing on furniture = 43%

Percentage of animals not to clawing on furniture = 29%

Percentage of animals not to fighting with other animals training cats = 17%

If the number of cat owners = 255

Number of owners trained their cat not to climb on furniture is given by

(43)/(100)* 255\n\n=0.43* 255\n\n=109.65\approx 110

If the number of cats owners = 316

Number of owners trained their cat not to claw on furniture is given by

(29)/(100)* 316\n\n=0.29* 316\n\n=91.64\approx 92

Hence, a) 110 b) 92

A. 110 owners
B. 92 owners
