Find the total cost, to the nearest cent, for a sweater that cost $22.95 with an additional 5.5% tax sale
Answer: $24.2
Step-by-step explanation:
The total cost will be gotten by adding the cost of the sweater and the tax. This will be:
Cost of sweater = $22.95
Tax = 5.5% × $22.95 = 0.055 × $22.95 = $1.26225
Total cost of the sweater = $22.95 + $1.26225 = $24.21225
= $24.2 to nearest cent
Answer:
5.5% of 22.95 is about 1.26
22.95 + 1.26 = 24.21
$24.21

A student makes and sells designer T-shirts to earn extra cash. The material needed to make each T-shirt costs $4.25. Currently, the student sells each designer T-shirt for $15. In an effort to increase sales, the student decides to spend $500 on promotional advertising. How many designer T-shirts must the student sell to break even? A. 26 B. 34 C. 46 D. 47
Step-by-step explanation:
Let x be the number of designer T shirts.
To break even,
Total Cost = Total Sales
Fixed Cost + Variable Cost = Total Sales
given the promotional advertising is classified under fixed cost,
[tex]500 + 4.25x = 15x \\ 15x = 500 + 4.25x \\ 15x - 4.25x = 500 \\ 10.75x = 500 \\ x = 500 \div 10.75 \\ = 46.5 \\ = 47 \: (round \: off \: to \: nearest \: whole \: number)[/tex]

Which of the following is TRUE about sampling distributions?
Larger sample gives worse data. More samples give worse data.
Larger sample gives better data. More samples give worse data.
Smaller sample gives worse data. More samples give better data.
Smaller sample gives better data. More samples give better data.
Answer:
Smaller sample gives worse data. More samples give better data.
Step-by-step explanation:
A sample is the number of elements that are used in a given experiment.
For example, if you do a survey to 100 random people, then your sample is 100 people.
Here we can see something kinda obvious, if you increase your sample, then more people answer your survey, wich means that more samples give more data, and more data is better, then more sample gives better data.
We also can see that if we have a small sample (for example 10 people) the survey will not be really useful, this happens because if we have really small samples the sample may be biased, and we always want to aboid this.
Then:
Smaller samples give worse data, and as we increase the samples, we also get better data.
The correct option is:
"Smaller sample gives worse data. More samples give better data."

Circumference:
C = 2πr
C = 2(3.14)(6.3)
C = 6.28(6.3)
C = 39.6
C = 2πr
C = 2π6.3
C = 12.6π

Find the volume of the figure below. Leave your answer in terms of π.
Answer: 1539π cubic inches.
Step-by-step explanation:
In the figure, we have a hemisphere joined with a cylinder of the same diameter 18 inches.
Radius = 9 inches (half of diamter)
Volume of hemisphere = [tex]\dfrac23 \pi r^3[/tex]
Volume of cylinder = [tex]\pi r^2 h[/tex], where r= radius h= height
Volume of hemisphere= [tex]\dfrac{2}{3}\pi (9)^3=486\pi in.^3[/tex]
Volume of cylinder = [tex]\pi (9)^2 (13)=1053\pi\ in.^3[/tex]
Combined volume = 486π+1053π=1539π cubic inches.
Hence, the volume of the solid = 1539π cubic inches.

Answer:
1.) 150
2.) 10
Step-by-step explanation:
If you look at the chart, above the 25 in the seconds row in the gallons row is 150.
This means that the chart tells you there are 150 gallons for every 25 seconds.
The second question asks about 60 gallons. So, if you look at 60 on the gallons row, and look below it on the seconds row, you see 10.
This means the chart tells you there are 60 gallons for every 10 seconds.

Area is length x width
Find area of 1 container:
Area = 5 1/2 x 1 2/3 = 11/2 x 5/3 = 55/6 = 9 1/6 square yards.
Multiply the area on 1 container by total containers (9)
9 1/6 x 9 = 55/6 x 9 = 495/6 = 82 1/2 square yards
The answer is 82 and 1/2 square yards
