P= #girls/#people. The number of girls is equal to 83-11= 72. So the probability is equal to 72/83 = 0.867. To convert the decimal into a percentage we simply multiply it by 100. So the probability is equal to 86.7%

five people, each working 8 hours a day, can assemble 400 toys in a five day work week. what is the average number of toys assem
vladimir1956 [14]

The question asks for the rate of toys per hour.

So we shall divide the total toys assembled by the total hours.

Its a five day week.

The number of hours allotted per day are 8.

So total allotted during the week are 8 × 5 = 40 hours.

Number of toys made during the week are 400.

Hence the number of toys assembled per hour per person

= number of toys / number of hours

= 400 / 40

= 10 toys per hour per person.

The average number of toys assembled per hour per person is 10.

Can you please show work please
-BARSIC- [3]

Answer:

1) y = 3x+5

2) y =  \frac{1}{2}x-4

3) y = -x + 0

4) y = -\frac{5}{3}x+8

5) y = \frac{3}{5} x - 7

Step-by-step explanation:

y = mx+b

In slope-intercept form, these are important to know:

- y and x should stay as variables

- m = slope of the line

- b = y intercept

Using the facts above⬆, we can solve these problems

Remember: Substitute m and b using the given information

1) y = 3x+5

2) y =  \frac{1}{2}x-4

3) y = -x + 0

4) y = -\frac{5}{3}x+8

5) y = \frac{3}{5} x - 7

Hope this helps :)

Have a great day!

I will give brainiest if correct
Natalka [10]
Its C. Add 3 and 15 which gives you 18. Then move the variable (4x) to the left. Then combine like terms which are the x’s and you should get 3x. Then divide both sides by 3. (18/3 = 6)
