Mark and Don are planning to sell each of their marble collections at a garage sale. If Don has 8 more than 2 times the number of marbles Mark has, how many does each boy have to sell if the total number of marbles is 68?
Step-by-step explanation:
Don (8+x)
Mark (2x)
Don + Mark = 68
(8+x) + 2x =68
x + 2x = 68-8
3x =60
x =20
Therefore, Don has 28 marbles while Mark has 40 marbles
The amount that each boy have to sell if the total number of marbles is 68 is : Don 16 and Mark 52
Let M represent Mark and D represent Don
Hence:
M+D= 68 marbles
M = 68-D
D = 2M+8
D = 2(68-D)+8
D = 136-2D+8
9D = 144
D = 16
Thus:
Don = 16
Mark =68-16= 52
The amount that each boy have to sell if the total number of marbles is 68 is : Don 16 and Mark 52

The coffee and soup machine at the local subway station is supposed to fill cups with 6 ounces of soup. Ten cups of soup are bought with results of a mean of 5.93 ounces and a standard deviation of .13 ounces. Construct a 99 percent confidence interval for the true machine-fill amount.
Answer:
99% Confidence Interval = (5.824,6.036)
Step-by-step explanation:
The coffee and soup machine at the local subway station is supposed to fill cups with 6 ounces of soup. Ten cups of soup are bought with results of a mean of 5.93 ounces and a standard deviation of .13 ounces. Construct a 99 percent confidence interval for the true machine-fill amount.
The formula for confidence interval
= Mean ± z × σ/√n
Mean of 5.93 ounces
Standard deviation of .13 ounces.
n = 10 cups
z= z score of 99% confidence interval = 2.58
Confidence Interval =
5.93 ± 2.58 × 0.13/√10
5.93 ± 2.58 × 0.0411096096
Confidence Interval = 5.93 ± 0.106
= 5.93 - 0.106
= 5.824
= 5.93 + 0.106
= 6.036
Hence, Confidence Interval = (5.824,6.036)

The amount of snowfall falling in a certain mountain range is normally distributed with a mean of 70 inches, and a standard deviation of 10 inches. What is the probability that the mean annual snowfall during 64 randomly picked years will exceed 72.8 inches
Answer:
The probability that the mean annual snowfall during 64 randomly picked years will exceed 72.8 inches is 0.3897
Step-by-step explanation:
Mean =[tex]\mu = 70 inches[/tex]
Standard deviation =[tex]\sigma = 10 inches[/tex]
We are supposed to find the probability that the mean annual snowfall during 64 randomly picked years will exceed 72.8 inches
We will use z-score formula :
[tex]Z = \frac{x-\mu}{\sigma}\\Z=\frac{72.8-70}{10}\\Z=0.28[/tex]
We will use z table
[tex]P(X \geq 72.8)=1-P(X\leq 72.8)=1-0.6103=0.3897[/tex]
Hence the probability that the mean annual snowfall during 64 randomly picked years will exceed 72.8 inches is 0.3897

It costs $0.50 to download an individual song in four dollars to download an album. Jada has $15 to spend downloading music.
1. Complete the table
2. Write an equation relieving number of individual songs ($) and the number of albums (A)
Answer:
1.
Number of individual songs, s Number of albums, a
6 3
22 1
30 0
If Jada buys 6 songs, she would have spent;
= 6 * 0.5 = $3
This would leave her with = 15 - 3 = $12
With each album costing $4, she can buy = 12/4 = 3 albums
If Jada buys 1 album, she would have spent $4
This would leave her with = 15 - 4 = $11
With each song costing $0.50, she can buy = 11/0.5 = 22 songs
If Jada buys 30 songs, she would have spent;
= 30 * 0.5 = $15
This would leave her with = 15 - 15 = $0
She wouldn't be able to buy any albums.
2. One song costs $0.50 so representing that would be;
= 0.50s
One album costs $4 so representing that is;
= 4a
Jada has $15 to spend so the songs and albums must add up to $15.
Equation therefore is;
0.5s + 4a = 15
