Justin=j
Marissa=m
Amy=a

j=2+1/3m
a=4+2j
<span>a=63

63=4+2(2+1/3m)
63=4+4+2/3m
55=2/3m
(55)3=(2/3m)3
165=2m
82.5=m
63=4+4+2/3(82.5)
63=8+55
63=63


j=2+2/3(82.5)
j=2+55
j=57
57=2+2/3(82.5)

Suppose you want to buy 100 pens. You can buy 100 pens at a 10% discount at one store where the price is $3.99 per pen. And you
Sliva [168]

Answer:

store 1 price after discount = $3.59

other store price after discount = $3.63

total price difference of 100 pens between store is $4

Step-by-step explanation:

given data

buy = 100 pens

discount at one store = 10 %

price = $3.99 per pen

discount at another store = 15%

price = $4.27 per pen

solution

we get here first discount at store one is

discount = pen price × discount rate .............1

discount = $3.99 × 10%

discount = $0.399

so price of pen at store 1

price of pen at store 1 after discount is

price after discount = $3.99 - $0.399

price after discount = $3.59

and

discount at other store is

discount = pen price × discount rate .............2

discount = $4.27 × 15%

discount = $0.64

so price of pen at other store  

price of pen at other store after discount is

price after discount = $4.27  - $0.64

price after discount = $3.63

and

Price of 100 pens after discount at store 1 = $3.59 × 100

Price of 100 pens after discount at store 1  = $359

and

Price of 100 pens after discount at other store =  $3.63 × 100

Price of 100 pens after discount at other store =  $363

so total price difference of 100 pens between store is $363  - $359  

total price difference of 100 pens between store is $4

A six-sided Fair number cubis rolled 100 times as part of an experiment. The frequency of the role of the number 3 is 20. W hich
Anastasy [175]

Answer:

The Theoretical probability is 1/6.

The experimental probability is 1/5

Step-by-step explanation:

Given

Rolls: 100

Outcome of 3 : 20

Required

Which of the options is true (See attachment for options)

From the attachment, we understand that the question requires that we calculate the experimental and theoretical probability.

The experimental probability (E) is calculated as thus:

E = \frac{Outcomes}{Total\ Rolls}

E = \frac{20}{100}

E = \frac{1}{5}

The theoretical probability (T) is calculated as thus:

A cube has 6 faces, one of which is the face 3.

So, T is:

T = \frac{n(face\ 3)}{n(Total)}

T = \frac{1}{6}

Hence, C is true

What is the mean for the data set?<br> 8 10 6 4<br> 12 6 8 14
Ipatiy [6.2K]

Answer:

<em>8.5</em>

Step-by-step explanation:

To find mean, we simply take the average of all the numbers in the data set, and divide in by the amount of values!

8+10+6+4+12+6+8+14= 68\\

68 ÷ 8 = 8.5!
