**Absurd answers won't be tolerated** They're about 50 students in a class that took a test. 21 of those students passed. If 13 students made a F, find the percent of 50 to 21. Explain.

Answers

Answer 1

Answer: About 10.5 passed.

Step-by-step explanation:

1. Convert 50% into a decimal.

First, convert 50% into a fraction, which is 1/2.

Divide 1/2 by its numerator and denominator.

1 / 2 = 0.5

Hence, the answer is 0.5.

Izzy deposits any money the team has left at the end of the season into a savings account, where it will remain until next season. This year, Izzy deposited $440 into a savings account that earns 312% simple interest. If the next season starts in 6 months, how much money will be in the account then? Explain

Answers

Answer: $447.04

Step-by-step explanation:

Amount (A) = Simple interest + Principal,

Simple interest = (Principal * rate * time)

A = (P * r * t) + P

Principal (P)= $440

rate (r)= 32% or 0.032 as a decimal

Justin wants to teach a hip-hop dance workshop. The cost of renting a dance studio is $149.50 plus $13 per person attending the workshop. Just can spend $323 at most to rent the space. What is the greatest number of people Justin can allow to attend the workshop? *



A. 13 people

B. 14 people

C. 28 people

D. 29 people

Answers

a. 13

first I subtracted 323 and 149.5 to get 173.5 I did this beacause you want to find out how much is left, then I divided 173.5 by 13 and got 13.

Answer:

A. 13 people

Step-by-step explanation:

The equation is 13x + 149.50 ≤ 323

Step 1: Subtract 149.50 from both sides.

13x + 149.5 − 149.5 ≤ 323 − 149.5

13x ≤ 173.5

Step 2: Divide both sides by 13

13x/13 ≤ 173.5/13

x<13.346154

Since you cant have 13.34 of a person you have to round to 13

So, the greatest number of people Justin can allow to attend the workshop is 13 people

    4/729  so 4 then /  then 729

Step-by-step explanation:

Your first term is 4 that is your starting point

Your common ratio is 1/3 so we will be multiplying by that

we will do this six times to get to the seventh term

so the second term is

4*1/3= 4/3

4/3 is our second term so we multiply it by 1/3 to get our third term

4/9 then fourth term is 4/9 *1/3

so 4/27

fifth should be 4/81

sixth should be 4/243

seventh should be 4/729

the points (-9,-3) and (-2,r) fall on a line with a slope of 1/7. What is the value of r?
If its not right im gonna report you

Answers

Answer:

R = -2

Step-by-step explanation

-9, -3 is the first point.

A slope of 1/7 means that for every one unit that "rises" it will have a "run" of 7 units.

-9 - 7 = -2

-3 - 1 = -2 (r)

with a slope of 1/7, (-9, -3) connects to (-2, -2)

Answer:

  6. 15/22

  7. 1/12

  9. 1/16

  10. 0

Step-by-step explanation:

6. 10 of the 12 tiles are "not P", so the probability of a "not P" on the first draw is 10/12 = 5/6. After drawing a "not P" on the first draw, 9 of the remaining tiles are "not P". The probability of drawing one of those is 9/11. So, the joint probability of drawing two "not P" tiles is ...

  (5/6)(9/11) = (5·9)/(6·11) = 15/22

__

7. The probability of drawing a tile worth 3 points is 3/12 = 1/4. The probability of drawing a tile worth 1 point is 4/12 = 1/3. So, the joint probability of drawing a 3-point tile, then a 1-point tile is ...

  (1/4)(1/3) = 1/12

__

9. There are 3 of the 12 tiles worth more than 4 points. The probability of drawing one of them  is 3/12 = 1/4. The probability of doing it again is also 1/4, so the probability of doing it twice is ...

  (1/4)(1/4) = 1/16

__

10. The probability of drawing a Z is 1/12. Having drawn a Z, the probability of drawing a 10-point tile is 0/11. The joint probability of drawing a Z twice is ...

  (1/12)(0/11) = 0
