Answer:

45.3 hours

Step-by-step explanation:

We are going to find the circumference of Earth's equator with $2\pi r$

First let's find the radius

Diameter = 7926

Radius = 7926/2 = 3963

Now use the the formula

$2\pi 3963=24900.26337$

24900.26337 ÷ 550 = <u>45.27320613</u>

Answer:

It would take around 7.2 hours!

Step-by-step explanation:

You need to find out what half of the equator is.

$\frac{7,926}{2}= 3,963$

Then you divide the mph (550) and the amount of miles. (3963)

$\frac{3,963}{550} = 7.205454545454545‬$

Explanation:

Add up all the frequencies in the table to see that there are 120+168+72 = 360 spins total.

Of those 360 spins, 120 of them land on red. The probability of landing on red is 120/360 = (120*1)/(120*3) = 1/3
Since 168 land on yellow, this means the probability of landing on yellow is 168/360 = (24*7)/(24*15) = 7/15
Lastly, we have 72 occurrences of blue out of 360 total spins. The probability of landing on blue is 72/360 = (72*1)/(72*5) = 1/5
