-3(-18) - y = 56

54 - y = 56

-y = 2

y = -2

Answers

Answer:If the last number is 1¼ then the answer is ¾

Step-by-step explanation:

From one fraction to the other there is a difference of ¼

¼+¼=½

½+½=¾

¾+¼=1

1+¼=1¼

To identify the difference between the fractions you should get the LCM of the denominator which is 4 then you change all the fractions and make them have the same denominator

½ ,²/4 ,_ ,⁴/4 ,⁵/4

Then work with the numerator

1 , 2, _ ,4 , 5,

The dash is to be filled with 3

So your answer is ¾

Compute the values of the three quartiles and the interquartile range. Q1 = Q2 = Q3 = IQR = b. Calculate the approximate value of the 82nd percentile. Enter an exact value: c. Find the percentile rank of 14. Round your answer to the nearest integer: %

Answers

Answer:

First arrange the data in an order

3, 3, 3, 7, 7, 10, 10, 12, 12, 13, 14, 17, 17, 18, 21

a.) Q1 = (N + 1)/4th item = (15 + 1)/4 = 4th item = 7

Q2 = 2(16)/4 = 16/2 = 8th item = 12

Q3 = 3(16)/4 = 3(4) = 12th item = 17

IQR = (Q3 - Q1)/2 = (17 - 7)/2 = 10/2 = 5

b.) 82nd percentile = 82(16)/100 = 13th item = 17

c.) 12 is the 8th item which is in the middle of the data set, so the percentile rank is 50%

Ms. Terry's class is hosting a fundraising
challenge. The students in her class are
divided into 4 teams. Each team has an
equal number of students. Do you have
enough information to find how many
students are on each team? Explain.

Answers

You do not have enough information because you need to know how many students are in the class to be able to divide them into 4 equal groups we do know that it has to be a positive integer that can be evenly divided by 4

In being able to find out whether it is possible to know the number of students on each team, there simply isn't enough information to do so.

In order to find out the number of students on each team, the following formula is necessary:

= Number of students in general / Number of teams

The number of teams is 4 so the denominator is present.

We however, do not have the number of students in general so we are unable to find out the number of students in each team.

In conclusion, we do not have enough information to find out the number of students in each team.

For her phone service, Rita pays a monthly fee of $17, and she pays an additional $0.05 per minute of use. The least she has been charged in a month is $83.90.

What are the possible numbers of minutes she has used her phone in a month?

Use M for the number of minutes, and solve your inequality for M.​

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Monthly fee = $17

Additional fee per unit of use = $0.05

Least amount she's been charged in a month = $83.90

Equation to represent the number of minutes 'M':

monthly fee + (additional fee per minute × M) = $83.90

Possible number of minutes :

83.90 ≤ $17 + 0.05M

$17 + $0.05 × M = $83.90

$0.05*M = $83.90 - $17

$0.05*M = $66.90

M = $66.90 / 0.05

M = 1,338 minutes

Your backyard is 27 feet longer than it is wide. Its area is 9718 square feet. What is the width Set up and solve a quadratic equation.

Answers

Answer:

Width = 86 feet

Step-by-step explanation:

Create two equations with the info:

L = 27 + W

where L represents the length and W the width of the backyard.

The other one is about the area of the rectangular backyard:

Area = L x W

where you replace the area with 9718 and the length (L) with (27 + W):

[tex]Area= L\,*\,W\\9718=(W+27)\,W\\9718=W^2+27\,W\\W^2+27\,W-9718=0[/tex]

and solve for W using the quadratic equation:

[tex]W=\frac{-27+/-\sqrt{27^2-4(1)(-9718)} }{2\,(1)} \\W=\frac{-27+/-\sqrt{39601}}{2} \\W=\frac{-27+/- 199}{2}[/tex]

This gives us two solutions:

W = - 113

and W = 86

We use the positive solution since this is a distance.

Therefore the width is: 86 feet
