Answer:

Step-by-step explanation:

Ok, this is an easy one. Step one: Find the Mean of the numbers by adding all the numbers 21, 45, 21, 14, 21, 28, 14, 24, and 28 which you will get according to my answer 220. Then you divide that by 9 since that there are 9 numbers listed above. When you divide you will get about 24.4 since you want it to be rounded to the neared tenth. Then you subtract 24.4 to all the number and when you get your answer, put the answer as |-3.4| for the first one so you will get a positive instead of a negative which is what we want. The second will be |20.6| which is 20.6 ans so on when we subtract. Then when you get all of that, you will need to add all those numbers and get a number and divide that by 9 because again there are 9 numbers. Now that you know that, you can do part b and c. Interpret means to depict something. For part C, you will need to use part A again and find the mean absolute deviation for part A again but without 45. And then explain the difference and how it affects the answer. To help with that, compare the 2 answers.

ATTENTION ATTENTION, BURNING QUESTION!!
AnnyKZ [126]
Recall the slope intercept form of an equation is:

y = mx + c, where m is the slope and c = vertical intercept.

y + 2 = 5x + 4

y + 2 = 5x + 4

y = 5x + 4 - 2

y = 5x + 2

So the slope intercept form is y = 5x + 2

Hope this helps.

Niles and Bob sailed at the same time for the same length of time. Niles' sailboat traveled 36 miles at a speed of 6 mph, while
kykrilka [37]

Answer:

Niles and Bob were traveling for 6 hours.

Step-by-step explanation:

The speed or rate at which an object is moving can be computed using the formula:

s=\frac{d}{t}

Here:

<em>s</em> = speed

<em>d</em> = distance traveled

<em>t</em> = time taken

It is provided that Niles and Bob sailed at the same time for the same length of time.

Speed of Niles sailboat is, <em>s</em>₁ = 6 mph.

Distance traveled by Niles' sailboat is, <em>d</em>₁ = 36 miles.

Speed of Bob's sailboat is, <em>s</em>₂ = 16 mph.

Distance traveled by Bob's sailboat is, <em>d</em>₂ = 96 miles.

It took both Niles and Bob the same time to travel the respective distance.

Compute the time it took Niles to travel 36 miles at 6 mph speed as follows:

t_{1}=\frac{d_{1}}{s_{1}}

   =\frac{36}{6}\\=6

It took Niles 6 hours to travel 36 miles at 6 mph speed.

Compute the time it took Bob to travel 96 miles at 16 mph speed as follows:

t_{2}=\frac{d_{2}}{s_{2}}

   =\frac{96}{16}\\=6

It took Bob 6 hours to travel 96 miles at 16 mph speed.

Thus, Niles and Bob were traveling for 6 hours.
