The manager of a grocery store wants to determine the average amount of money spent at his store as it compares to the average d
Nezavi [6.7K]

Answer:

The average spent at his store is of $37.60.

The average spent at his competitor's store is of $48.53.

Step-by-step explanation:

Average of a data set:

The mean of a data set is the sum of all values divided by the number of values.

His store:

15 orders.

Prices of: 41, 38, 19, 30, 21, 53, 34, 34, 37, 29, 50, 43, 57, 28, 50

The average is:

M = \frac{41 + 38 + 19 + 30 + 21 + 53 + 34 + 34 + 37 + 29 + 50 + 43 + 57 + 28 + 50}{15} = 37.6

The average spent at his store is of $37.60.

Store of the competitor:

15 orders

Prices of: 86, 15, 75, 40, 51, 60, 27, 45, 112, 7, 65, 31, 18, 27, 69

The average is:

M = \frac{86 + 15 + 75 + 40 + 51 + 60 + 27 + 45 + 112 + 7 + 65 + 31 + 18 + 27 + 69}{15} = 48.53

The average spent at his competitor's store is of $48.53.

I need help. So it says to find the shaded area, and I'm not really good a things like this
krek1111 [17]

Answer:

86 cm²

Step-by-step explanation:

<u>1) Calculate the area of the square</u>

A=lw\\A=20*20\\A=400

Therefore, the area of the square is 400 cm².

<u>2) Calculate the area of the circle</u>

A=\pi r^2\\

\pi we can substitute with 3.14. To find the radius, we divide the diameter of the circle by 2. 20 cm is the diameter of the circle, so therefore, its radius is 10 cm.

A=3.14*10^2\\A=3.14*100\\A=314

Therefore, the area of the circle is 314 cm².

<u>3) Subtract the area of the circle from the area of the square</u>

A=400-314\\A=86

Therefore, the area of the shaded region is 86 cm².

I hope this helps!
