Question 4

Answer:

2

Step-by-step explanation:

Given

See attachment for chart

Required

Number of off days

To do this, we simply calculate the expected value of the chart.

This is calculated as:

E(x) = \sum x * f

Where

x = days

f = chances

So, we have:

E(x) = 0* 0.3 + 1 *0.2 + 2 * 0.25 + 3  * 0.2 + 4  * 0.02 + 5 * 0.01 + 6 * 0.01 + 7 * 0.01

E(x) = 1.56

E(x) \approx 2

28 + 2A = 5A + 7<br><br> Please explain thank you!
Vinvika [58]
First you need to get x on one side of the equation and to do that subtract 2a from both sides.
28 + 2a = 5a + 7
-2a -2a
28=3a+7

Then we need to get a alone by subtracting 7 on both sides.
28=3a+7
-7 -7
21=3a

Finally divide each side by 3 and you should get a = 7. Hope this helps!

the perimeter of a rectangular field is 346 yards if the length of the field is 92 yards what is its width
Maslowich

the formula for the perimeter of a rectangle is

P= 2(L+W)

with L representing length and W representing width

since we have the perimeter and the length, we can plug the values into the equation to find W

346 = 2(92+w)

346 = 184 + 2W

162 = 2W

81 = W

the width of the field is 81 yards.

hope this helped!
