Answer:
$10.50 is the tip on a dinner bill.
Step-by-step explanation:
The first step is to round off $67.42. It is closer to 70 than 60, therefore it is 70.
Secondly, 10% of 70 is 7.
5% of 7 is 3.5.
*Notice that 10% and 5% equals 15%.
Add 7 + 3.5 = 10.5 or $10.50

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)

In a direct variation, y = 16 when x = 4. Write a direct variation equation that shows the
relationship between x and y.
Write your answer as an equation with y first, followed by an equals sign.
In a direct variation, y = 16 when x = 4. The direct variation equation shows the relationship between x and y will be y=4x.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that,
y = 16 when x = 4
There are often two different sorts of variables in analytics. We obtained that independent variables will have an impact on dependent variables. What occurs as a result of the independent variable is referred to as a dependent variable.
In the given equation x is the independent variable while y is the dependent variable.
16 = 4(4)
y=4x
Thus, in a direct variation, y = 16 when x = 4. The direct variation equation shows the relationship between x and y will be y=4x.

All the factors of 200 and all the factors of 300 are factors of 600. True or false and explain.
Answer:
true because 200 and 300 are factors of 600
Step-by-step explanation:
Answer:
I don't think so
Step-by-step explanation:
600 is a composite number.
Prime factorization: 600 = 2 x 2 x 2 x 3 x 5 x 5, which can be written 600 = (2^3) x 3 x (5^2)
The exponents in the prime factorization are 3, 1 and 2. Adding one to each and multiplying we get (3 + 1)(1 + 1)(2 + 1) = 4 x 2 x 3 = 24. Therefore 600 has exactly 24 factors.
Factors of 600: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 25, 30, 40, 50, 60, 75, 100, 120, 150, 200, 300, 600
Factor pairs: 600 = 1 x 600, 2 x 300, 3 x 200, 4 x 150, 5 x 120, 6 x 100, 8 x 75, 10 x 60, 12 x 50, 15 x 40, 20 x 30 or 24 x 25
Taking the factor pair with the largest square number factor, we get √600 = (√100)(√6) = 10√6 ≈ 24.494897. (Note: 2 + 4 = 6 and 49 + 48 = 97 so this square root and √6 can be easy to remember.)

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

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

Answer:
#20 = 13
#21 = 1
#22 = -3
Step-by-step explanation:
Replace all of the x values in the equations for the one in the table.
Then solve.
This is the equation
Y= -4x - 3
A. x = -4
Replace x with -4.
Y = -4 (-4) - 3
Solve.
Y = 16 - 3
Y = 13
#20 = 13
B. x = -1
Replace x with -1
Y = -4 (-1) - 3
Solve.
Y = 4 - 3
Y = 1
#21 = 1
C. x = 0
Replace x with 0.
Y = -4 (0) - 3
Solve.
Y = 0 - 3
Y = -3
#22 = -3
