Answer 2

Answer:

Answer:

y=1/2x-6

Step-by-step explanation:

y-y1=x(x-x1)

y-(-7)=1/2(x-(-2))

y+7=1/2(x+2)

y+7=1/2x+1

y=1/2x-6

The volleyball team and the wrestling team at Newberry High School are having a joint car wash today, and they are splitting the revenues. The volleyball team gets $4 per car. In addition, they have already brought in $24 from past fundraisers. The wrestling team has raised $84 in the past, and they are making $1 per car today. After washing a certain number of cars together, each team will have raised the same amount in total. What will that total be? How many cars will that take?

Answers

Answer: After washing 20 cars together, each team will have raised the same amount in total.

Step-by-step explanation:

Let x represent the number of cars that each each teams will wash for them to raise the same amount in total.

The volleyball team gets $4 per car. In addition, they have already brought in $24 from past fundraisers. This means that the total amount raised by the volleyball team after washing x cars would be

4x + 24

The wrestling team has raised $84 in the past, and they are making $1 per car today. This means that the total amount raised by the wrestling team after washing x cars would be

x + 84

For both amounts to be equal, the number of cars would be

4x + 24 = x + 84

4x - x = 84 - 24

3x = 60

x = 60/3

x = 20

11 kl = _____ l

1.1
110
1,100
11,000

Answers

Answer:

11,000

Step-by-step explanation:

The kl is a kiloliter.

10 milliliter makes a centiliter, 10 centiliter makes a deciliter and 10 deciliter makes a liter.

10 liters (l) make a decaliter, 10 decaliter makes a hectoliter and 10 hectoliter makes a kiloliter (kl).

As such, 1000 l = 1kl

11kl = 11 × 1000l

= 11,000l

the answer is 11,000

GCF of 24 , 36 , and 60

Answers

   24         36      60
1 × 24 1 × 36 1 × 60
2 × 12 2 × 18 2 × 30
3 × 8 3 × 12 3 × 20
4 × 6    4 × 9    4 × 15
      6 × 6 5 × 12
      6 × 10

GCF(24, 36, 60) = 12

To find the greatest common factor of any set:
1) List their prime factorizations.

24 = 2³ × 3
36 = 2² × 3²
60 = 2² × 3 × 5

2) Multiply together any factor these all share.

2² × 3 = 12 (GCF)

Question

The times of all 15 year old who run a certain race are approximately normally distributed with a given mean Mu = 18 sec and standard deviation Sigma = 1. 2 sec. What percentage of the runners have times less than 14. 4 sec?.

Answer:

A. 0.15%

Step-by-step explanation:

The times of all 15 year old who run a certain race are approximately normally distributed with a given mean as 18 sec and standard deviation as 1.2 sec.

We know that,

where,

X = raw score = 14.4

μ = mean = 18

σ = standard deviation = 1.2

Putting the values,

Finding the the probability from z score table, we get
