Step-by-step explanation:

OpenStudy (judygreeneyes):

Hi - If you are working on this kind of problem, you probably know the formula for the probability of a union of two events. Let's call working part time Event A, and let's call working 5 days a week Event B. Let's look at the information we are given. We are told that 14 people work part time, so that is P(A) = 14/100 - 0.14 . We are told that 80 employees work 5 days a week, so P(B) = 80/100 = .80 . We are given the union (there are 92 employees who work either one or the other), which is the union, P(A U B) = 92/100 = .92 .. The question is asking for the probability of someone working both part time and fll time, which is the intersection of events A and B, or P(A and B). If you recall the formula for the probability of the union, it is

P(A U B) = P(A) +P(B) - P(A and B).

The problem has given us each of these pieces except the intersection, so we can solve for it,

If you plug in P(A U B) = 0.92 and P(A) = 0.14, and P(B) = 0.80, you can solve for P(A and B), which will give you the answer.

I hope this helps you.

Answer:

The probability that a randomly selected employee works both part time and 5 days each week is 0.02

Step-by-step explanation:

What is probability?

Probability is a branch of math which deals with finding out the likelihood of the occurrence of an event.

The total employees =100

Let A= Employees who work part time = 14

and B = Employees who work 5 days each week = 80

Then, A∪B= 92

We have to find, P(A∩B)

P(A∪B)=P(A)+P(B)-P(A∩B)

[tex]\frac{92}{100}=\frac{14}{100}+\frac{80}{100}-[/tex]P(A∩B)

0.92=0.14+0.8-P(A∩B)

0.92=0.94-P(A∩B)

P(A∩B)=0.02

Hence, the probability that a randomly selected employee works both part time and 5 days each week is 0.02.

Answer:

[tex]Persephone = 27\frac{3}{7}[/tex]

[tex]Madison = 20\frac{4}{7}[/tex]

Step-by-step explanation:

Given

[tex]Pages = 48[/tex]

[tex]P=8\ mins[/tex] --- Persephone

[tex]M = 6\ mins[/tex] --- Madison

The question is incomplete, however a possible question could be:

To determine the number of pages colored by each of them

First, we determine the ratio of time spent by each:

[tex]P : M = 8 : 6[/tex]

The number of pages covered by Persephone is:

[tex]Persephone = \frac{P}{P + M} * Pages[/tex]

[tex]Persephone = \frac{8}{8+6} * 48[/tex]

[tex]Persephone = \frac{8}{14} * 48[/tex]

[tex]Persephone = \frac{384}{14}[/tex]

Simplify

[tex]Persephone = 27\frac{3}{7}[/tex]

This implies that Madison colors the remaining pages.

This is calculated as:

[tex]Madison = Pages - Persephone[/tex]

[tex]Madison = 48 - \frac{384}{14}[/tex]

Take LCM

[tex]Madison = \frac{48 * 14 - 384}{14}[/tex]

[tex]Madison = \frac{288}{14}[/tex]

Simplify

[tex]Madison = 20\frac{4}{7}[/tex]

Answer:

m<X= 36.87 degrees

Step-by-step explanation:

Since the triangle abc and xyz are similar, hence;

m<C = m<Y

90 = x - 5

Add 5 to both sides

90+5 = x-5+5

95 = x

Swap

x = 95

m<Y = x - 5

m<Y = 95 - 5

m<Y = 90

Find m<X

Using the SOH CAH TOA

Opposite to m<X = YZ = 6

Adjacent = 8

Tan M<X = opp/adj

Tan m<X = 6/8

m<X = arctan(6/8)

m<X= 36.87 degrees

Answer:

g(x) = |x+3|-2

Step-by-step explanation:

to move horizontally replace each x with (x ± c)

if you move it to the right, you need x - c

if you move it to the left , you need x + c

so , since we are moving 3 units to the left, we replace the x with x+3

g(x) = |x+3|-2

90 x 120 = 10800

10800/2 = 5400

Answer:

Step-by-step explanation:

so this is the problem:

90x120=x/2

first, you can multiply 90 and 120 to get 10800.

then, your equation looks like this

10800=x/2

you can multiply both sides by 2

2(10800)=(x/2)(2)

then, you get this

21600=x

Answer:

134 square inches

Step-by-step explanation:

To find surface area, you must find the individual area of each face of the shape. There are 6 faces on every cube or other rectangular prism, so you must perform 3 equations, as every face has an identical face on the opposite side. The formula for regular area is Length (l) times Width (w).

Large sides on front and back: 8x6=48

Slim sides to the right and left: 1x6=6

Slim sides on top and bottom: 8x1=8

Then combine:

48+48+6+6+8+8=134

Answer:

1/36

Step-by-step explanation:

Probability is the likelihood of chance that an event will occur. Mathematically,

Probability = expected outcome/total outcome

If a bag contains two white blocks, one red block and 3 purple block

Total outcome = 2+1+3= 6

Probability that white ball is selected = 2/6

Probability that red ball is selected = 1/6

Probability that white ball is selected = 3/6

Probability of picking a ball is 2/6 × 1/6 × 3/6

Probability of picking a ball = 6/216

Probability of picking a ball = 1/36
