Find the circumference:

Circumference = pi x radius x 2 = 138.16 feet


Linear travel = circumference x rotations


linear travel = 138.16 x 20 = 2.763.2 feet.
Round off to 2,763 feet

Select the correct comparison set a set b O A the typical value is greater is set a the spread is greater in set b
salantis [7]

Answer:

(a)

Step-by-step explanation:

Given

See attachment for sets A and B

Required

The true statement about both sets

First, we calculate the typical values (mean) of set A and set B.

This is calculated as:

Mean = \frac{\sum fx}{\sum f}

For A:

A= \frac{0*1+2*1+5*1+6*1+7*1}{1+1+1+1+1}

A= \frac{20}{5}

A =4

For B:

B = \frac{7 * 1 + 8 *1 + 9 * 2 + 10 * 1}{1+1+2+1}

B = \frac{43}{5}

B = 8.6

<em>Here, we can conclude that B has a larger typical value</em>

Next calculate the spread (range) of sets A and B

This is calculated as:

Range = Highest -Least

For A:

A = 7 - 0

A = 7

For B

B=10 - 7

B = 3

<em>Here, we can conclude that A has a larger spread.</em>

<em></em>

<em>Hence, (a) is true</em>

5: 25 degrees
8: 48 degrees

Still working on the other ones

Explanation
- for 5 we know that the straight line has a measurement of 180 degrees so we just add 125 and 30 to get 155 and 155 plus 25 is 180 degrees

- For 8 we know that the measurements of AED are 89 degrees and we know two other angles are 29 and 12 which make 41 if you add them and we know that 41 + 48= 89 which is what we wanted to get to
