And or both means we multiply the given probability situations that are mutually exclusive and exhaustive - they cannot occur at the same time.

let P(a)=x

then: P(b) * P(a) =3/4

         15/16 * x = 3/4

          15x/16 = 3/4
therefore x= 3/4 *16/15
          x = 4/5
P(a) = 4/5

hope it's clear

The volume of a cube is 8 in^3 What is the length of one side?
stepladder [879]

Answer:

2 in

Step-by-step explanation:

Use the cube volume formula, V = s³, where s is the side length

Plug in 8 as V and solve for s:

V = s³

8 = s³

Take the cube root of both sides:

2 = s

So, the length of one side is 2 inches.

An employment agency specializing in temporary construction help pays heavy equipment operators
pochemuha
Answer:
Number of heavy equipment operators hired were 22
Number of general laborers hired were 11

Explanation:
Assume that number of heavy equipment operators hired is x and that number of general laborers is y.

We are given that:
1- Total number of hired people is 33. This means that:
x + y = 33
This can be rewritten as:
x = 33 - y ...........> equation I
2- heavy equipment operators are paid $135, general laborers are paid $89 and that the total payment was $3949. This means that:
135x + 89y = 3949 ............> equation II

Substitute with equation I in equation II and solve for y as follows:
135x + 89y = 3949
135(33-y) + 89y = 3949
4455 - 135y + 89y = 3949
506 = 46y
y = 506 / 46
y = 11

Substitute with y in equation I to get the value of x as follows:
x = 33 - y
x = 33 - 11
x = 22

Hope this helps :)

Eden needs an average of 92% on her quiz scores to earn the grade she wants in science class. Each quiz is worth 20 points.
Jlenok [28]

Answer:

19 points

Step-by-step explanation:

convert points to percents:

20 points = 100%

19 points = 95%

18 points = 90%

17 points = 85%

percent-wise, her average prior to another quiz is 92.5

so if she wants to keep to maintain that average she must get 18 1/2 points; if teacher doesn't award partial credit then she needs to get a full 19 points
