Answer:

Step-by-step explanation:

Using the cosine ratio in the right triangle.

cos66° = $\frac{adjacent}{hypotenuse}$ = $\frac{13}{x}$ ( multiply both sides by x )

x × cos66° = 13 ( divide both sides by cos66° )

x = $\frac{13}{cos66}$ ≈ 32.0 ( to the nearest tenth )

wolverine [178]

Let's take this problem step-by-step:

Let's take the case of the tennis ball first:

⇒ the diameter of the balls are 2.7inches

⇒ therefore they are spheres with diameters of 2.7 inches

⇒ for an x-ray they are circles with a diameter of 2.7in

Now for the cylinder container:

⇒ It has a width of 2.7inches

⇒ Its height:

⇒ is three balls stacked together

⇒ Height is 3 * 2.7in = 5.4 inches

⇒ Overall dimension: A rectangle that is 2.7 in x 8.1 in

Answer:

A circle with a diameter of 2.7 in
A rectangle that is 2.7 in x 8.1 in

Hope that helps!

Answer the statistical measures and create a box and whiskers plot for the following set of data. 4,4,5,5, 6, 6, 8, 10, 11, 11,

vredina [299]

Answer:

Step-by-step explanation:

First you take your smallest number, which in this case is 4 - then you find your maximum number which is 14. Then we can list these numbers on a piece of paper and cross a number out from each side until you reach the middle number which would be 8. Then you go from the min to the middle number which would be 5. Then you repeat between the max number and the middle number which is 11. So your minumum would be 4, max would be 14, Q1 would be 5 Median would be 8 and Q3 would be 11. Let me know if I got it right! I haven't done it for a while, but I am pretty sure this is correct..
