X=-4
y=-2
since you have +and - 7y you add the whole expression both sides together
you get
3x=-12
solve for x and get x=-4
plug this in for x and you get -2 for y in either equation

Answer is –4/5

Rearrange the equation to make y the subject

5y = –4x – 35

y = –4/5 x – 7

If the line is parallel to the other line, they both have the same gradients but different y-intercepts, so the gradient is just as is.

If a normal distribution has a mean of 132 and a standard devistion of 20, what is the value that has a z score of 3.6

nika2105 [10]

z = (x - μ)/σ

Substituting given values, you have

3.6 = (x - 132)/20

(20)(3.6) = x - 132 . . . . multiply by 20

72 + 132 = x . . . . . . . . .add 132

204 = x

The value that has a z-score of 3.6 is 204.

The following distribution shows the frequency of daily revenue for an Italian restaurant in Wilmington, Delaware. Revenue Frequ

sergejj [24]

Answer:

The probability that a randomly selected day will generate more than $6,000 in revenue is 0.325.

Step-by-step explanation:

The frequency distribution of daily revenue for an Italian restaurant in Wilmington, Delaware is:

Revenue Frequency

Under $2,000 18

$2,000 - $4,000 10

$4,000 - $6,000 26

$6,000 - $8,000 14

$8,000 - $10,000 8

Over $10,000 4

Total 80

The probability of an event E is defined as:

$P(E)=\frac{n(E)}{N}$

Here,

n (E) = favorable outcome

N = total outcomes

The favorable outcomes of the event X : "more than $6,000 in revenue" is defined as:

n (X) = 14 + 8 + 4 = 26

Total number of outcomes is, N = 80.

Compute the probability of the event X is:

$P(X)=\frac{n(X)}{N}=\frac{26}{80}=0.325$

Thus, the probability that a randomly selected day will generate more than $6,000 in revenue is 0.325.

Will ran four miles on his first day of training.The next hint he ran one-third that distance.How far did he run the second day?

zhenek [66]

4 miles = 1 day

4miles divided by 1/3 distance on 2nd day = 1.33 miles ran on second day
4/1 x 1/3=4/3 4 divided by 3= 1.33 miles ran on the second day
If Will ran 1/3 of the distance that he ran on the first day (4 miles) the second day, he ran 1.33 miles
