77julia77 [94]

Rate for Sally is 1 room per 8hrs
rate for Steve is 1 room per 7hrs

combined rate:
1/8 + 1/7 = 1/T
7/56 + 8/56 = 1/T
15/56 = 1/T
56/15 = T

What is the mean absolute deviation of the data set?

Ronch [10]

Answer:

the mean absolute deviation of the data set is 2.

Step-by-step explanation:

To calculate the mean absolute deviation of a data set, we need to follow the following steps:

Step 1: Calculate the mean.

Step 2: Calculate how far away each data point is from the mean (always keeping a possitive distance).

Step 3: Calculate the mean of the deviations.

Step 1: The mean of the data set is:

Mean = (12 + 10 + 10 + 8 + 6+ 7 + 7 + 12)/8 = 72/8 = 9

Step 2:

{12 -9, 10-9, 10-9, 9-8, 9-6, 9-7, 9-7, 12-9} = {3, 1, 1, 1, 3, 2, 2, 3}

Step 3: (3 + 1 + 1 + 1 + 3 + 2 + 2 + 3)/8 = 2

In conclusion, the mean absolute deviation of the data set is 2. Which corresponds to the option B.

Remi has two cone-shaped containers with the same diameter. He will place the smaller container inside the larger one. Before he

Keith_Richards [23]

Given:
Big cone : diameter = 12 cm ; height = 18 cm ; base = 14 cm
Small cone: diameter = 12 cm ; height = 6 cm ; base = 14 cm

Volume of a cone-shaped container = π r² h/3
Big cone:
V = 3.14 * (6cm)² * 18cm/3
V = 3.14 * 36cm² * 6cm
<span>V = 678.24 cm³

</span>Small cone:
V = 3.14 * (6cm)² * 6cm/3
V = 3.14 * 36cm² * 2cm
<span>V = 226.08 cm³

</span>Big cone - small cone = volume of water
678.24 cm³ - 226.08 cm³ = 452.16 cm³

Maru [420]

Answer:

Step-by-step explanation:

Triangles EFG and FGH are similar.

x/15 = 36/39

x/15 = 12/13

x = 15*12/13 = 180/13 ≈ 13.8 units

A new business center in town was built in a shape of a regular nonagon. Each side is 160 feet long which is the area occupied b

charle [14.2K]

Answer:

158,254.08 ft²

Step-by-step explanation:

A nonagon is a polygon with 9 sides and 9 angles. A regular nonagon has all equal sides and all equal angles. In order to find the area of a nonagon, you can use the formula:

A = $\frac{9}{4}a^{2}cot(\frac{180}{9})$ where 'a' represents the length of one side

Calculating the known measurements ahead of time, we get a condensed, or simplified formula:

A = 6.1818 x a²

Using the side length of 160 ft:

A = 6.1818 x 160² = 158,254.08 ft²
