Which Of The Following Is The Best Estimate Of The Measure Of The Angle The Skateboard Makes With The

Answers

Answer 1

Answer:

Correct choice: C. 74.5

Step-by-step explanation:

Trigonometric Ratios

In every right triangle (those who have an internal angle of 90°), the six trigonometric ratios are valid. They relate the other internal angles with the lengths of the triangle.

The skateboard, the wall, and the ground form a right triangle. We need to find the measure of the angle formed by the skateboard with the ground. Let's call it β. In a right triangle, the cosine of an angle is defined as

[tex]\displaystyle \cos\beta=\frac{\text{adjacent leg}}{\text{hypotenuse}}[/tex]

The adjacent leg of β is the side with length 8 in, and the hypotenuse is the length of the skateboard, 30 in, thus:

[tex]\displaystyle \cos\beta=\frac{8}{30}}=0.267[/tex]

Using a digital calculator we find:

[tex]\beta=\cos^{-1}(0.267)[/tex]

[tex]\beta=74.5^\circ[/tex]

Correct choice: C. 74.5

Sample A has a mean of M = 6. Sample B has a mean of M = 10. When the two samples are combined, the mean of the combined group is M = 9. Which of the following is the most accurate description for the two sample sizes?


The samples are the same size.

Sample A is much bigger than Sample B.

There is not enough information provided to determine this.

Sample B is much bigger than Sample A.

Answers

Answer:

Sample B is much bigger than Sample A

Step-by-step explanation:

It is because when seeing sample B alone we can see it has a larger mean than of Sample A. Mean is greater when the values we are using are of bigger value. Since Sample B has bigger values in it so it also a has bigger mean compared to Sample A which has a smaller mean (smaller values in it)

A 12-ounce sports drink costs 0.96 and a 16-ounce sports drink costs $1.12. Which size is the best
buy? How much cheaper is it? Ratios

Answers

Answer:

It is better to buy the 16-ounce drink and it is 0.01 cent cheaper

Step-by-step explanation:

We have to find out how much each sports drinks cost per ounce.

0.96 ÷ 12 = 0.08 per ounce

1.12 ÷ 16 = 0.07 per ounce

It is better to buy the 16-ounce drink and it is 0.01 cent cheaper

Hope this Helps! :)

Slope: 4/7

Step-by-step explanation:

First off you need to graph these equation on a graph i recommend using Desmos, it is free you can search it up. After you graph you need to focus on rise/run. this is simple, count how many times you go up before you reach the point diagnolly, then go over however many until you reach the point. Write it in a fraction such as, 2/1, this would be your slope, 2.
