Answer:

11.04

Step-by-step explanation:

Given the data:

29, 15, 22, 52, 38

The mean absolute deviation :

Mean, m = Σx / n

n = sample size = 5

29 + 15 + 22 + 52 + 38 = 156

Mean = 156 / 5 = 31.2

Mean absolute deviation (MAD):

Σ|x - m| / n

(|29 - 31.2| + |15 - 31.2| + |22 - 31.2| + |52 - 31.2| + |38 - 31.2|) / 5

(2.2 + 16.2 + 9.2 + 20.8 + 6.8) / 5

55.2 / 5

= 11.04

a furniture rental store charges a down payment of $100 and $72.50 per month for a table. Hilde paid $535 to rent the table. Sol
elixir [45]

We are given : In a furniture rental store a down payment  = $100.

Monthly charge of the table = $72.50 per month.

Total amount to be paid for the table = $535.

Let us assume number of months be n for which Hilde rented the table.

We are given equation also 72.50n + 100 = 535.

We need to solve the equation for n.

72.50n + 100 = 535.

<em>Subtracting 100 from both sides, we get </em>

72.50n + 100-100 = 535-100

72.50n = 435

<em>Dividing both sides by 72.50, we get </em>

72.50n/72.50 = 435/72.50

n = 6.

<h3>Therefore, for 6 months Hilde rented the table.</h3>

How high would a 2 story building be?
masha68 [24]
This would definitely vary but if I were to say I would probably think each story would be about 10 feet so it so 2 stories should be about 20 feet. but keep in mind that every building is unique.

Brandi jogged 2 1/2 miles in 30 minutes. Sharna jogged 3 1/2 miles in 3/4 hour. who jogged at a slower rate.
Klio2033 [76]
You need to use the equation Distance (miles)=Rate (miles/hour) x Time (hours)

Brandi: 2.5 miles=rate (1/2 hour) r=5 miles per hour

Sharna=3.5 miles= rate (3/4 hour) r = 7 miles per hour.

Therefore brandi jogged at a slower rate.
