Answer:

x = - 13.5 or - 13½

Step-by-step explanation:

9 / - 10

= - 9 / 10

= - ( 9 / 10 )

9 / 10 in decimal is 0.9

= - 0.9

- 0.9 = x / 15

Cross multiply,

x = - 0.9 * 15

x = - 13.5

- 13.5 in mixed fraction = - 13½

Tomato juice is sold in a case with 8 cans. Complete the table to show the relationship between the number of cases and the numb
tangare [24]

Step-by-step explanation:

1 case- 8 cans

If you have 32 cans and you know that 1 case can have 8 cans you do this:

32:8=4 cases

Then if you have 10 cases in each you get 8 cans so it equals:

10*8=80cans

And last:

You have 96 cans and again you know that one case can contain 8 cans so it is:

96:8=12 cases

When you write that:

1. answer: 8

A set of computer science exam scores are normally distributed with a mean of 71.33 point, and a standard deviation of 3 points.
Bess [88]

Answer: 0.86 of the exam scores are between 68 and 77.99 points

Step-by-step explanation:

Since the set of computer science exam scores are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = computer science exam scores .

µ = mean score

σ = standard deviation

From the information given,

µ = 71.33 points

σ = 3 points

We want to find the proportion of the exam scores are between 68 and 77.99 points. It is expressed as

P(68 ≤ x ≤ 77.99)

For x = 68,

z = (68 - 71.33)/3 = - 1.11

Looking at the normal distribution table, the probability corresponding to the z score is 0.13

For x = 68,

z = (77.99 - 71.33)/3 = 2.22

Looking at the normal distribution table, the probability corresponding to the z score is 0.99

P(68 ≤ x ≤ 77.99) = 0.99 - 0.13 = 0.86

Pasha works as a food scientist. He designed a recipe for crackers that are 40% wheat flour by weight. He made a test batch of t
MA_775_DIABLO [31]
To answer this question, you need to find 40% of 1 1/2. To find a percentage of a value, you can divide the percentage by 100 and multiply that by the total.

In this situation, 40 / 100 = 0.4
So 1 1/2 x 0.4 = 0.6

Pasha will use 0.6 pounds of wheat flour in the test batch.
