94 + 56 + 4.5x + x + 1.5x = 360150 + 7x = 3607x = 210x = 30

Sum of interior angles of a pentagon is:

(5 - 2)*180 = 540

Sum of interior angles of a given pentagon:

72 + 3x + 89 + 99 + 2x = 5405x + 260 = 5405x = 280x = 280/5x = 56

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.

Answers

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."

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

Answers

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]

Answers

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.

Find the total cost, to the nearest cent, for a sweater that cost $22.95 with an additional 5.5% tax sale

Answers

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
