Ben is greeting customers at a music store. Of the first 20 people he sees enter the store, 9 are wearing jackets and 11 are not. What is the experimental probability that the next person to enter the store will be wearing a jacket? Enter your answer as a simplified fraction.

Answers

Answer 1

Answer:

The experimental probability that the next person to enter the store will be wearing a jacket is 9/20.

How to calculate the experimental probability?

The experimental probability of an event is defined as the ratio of the number of times the event occurs to the total number of trials or observations.

In this case, we have observed 20 people, and 9 of them were wearing jackets. Therefore, the experimental probability that the next person to enter the store will be wearing a jacket is:

P = Number of people wearing jackets / Total number of people observed

P = 9/20

Therefore, the experimental probability that the next person to enter the store will be wearing a jacket is 9/20.

What is the solution to the equation-4x - 14 = 6?

Answers

Answer:

x=-5

Step-by-step explanation:

-4x - 14 = 6

Add 14 to each side

-4x - 14+14 = 6+14

-4x = 20

Divide each side by -4

-4x/-4 = 20/-4

x = -5

Forty students are in fun club. Of those, 45% are girls. This percent increases to 56% after new girls join the club. How many new girls join? ~SwaggyAmerikanXO

Answers

45% of 40 is 0.45×40=18 girls
if x girls join then 56% of 40+x is 0.56(40+x)=18+x
22.4+0.56x=18+x
put together like terms
4.4=0.44x
x=10 girls joined

45% of 40 is 0.45×40=18 girls

if x girls join then 56% of 40+x is 0.56(40+x)=18+x

22.4+0.56x=18+x

put together like terms

4.4=0.44x

x=10 girls joined

What is 84.5% as a decimal

Answers

To convert ANY percent into decimal form ALL we need to do is DIVIDE the percent by 100. So lets do that:-

84.5 ÷ 100 = 0.845

So, 84.5% as decimal is 0.845.

Hope I helped ya!!!!!!!

0.845 because A. I've done this before and B. because if you have a percentage sign you have to add the decimal at the front (i think don't quote me)

Answer:

Step-by-step explanation:

1) 4x + 3 <= 3x - 5

Subtract 3 from both sides

4x + 3-3 <= 3x - 5 -3

4x <= 3x - 8

Subtract 3x form both sides

4x - 3x <= 3x -3x - 8

x <= -8

Answer:

CHALLENGE ACCEPTED!!

Step-by-step explanation:

4x + 3 ≤ 3x - 5

4x - 3x ≤ -5 -3

x ≤ -8

sorry, cant draw the number line but hope the solution helps.

-2x > 6

-2x ÷ -2 > 6 ÷- 2

x > -3

1/8(3x - 16) < 4

3/8x - 2 < 4

3/8x < 4 + 2

3/8x < 6

x = 16

x - 3/2 ≥ -5

x - 3 ≥ -5 × 2

x - 3 ≥ -10

x ≥ -10 + 3

x ≥ 7
