Vicki measured the midnight temperatures in 4 locations in Alaska. The temperatures were -7, -2, 1, 4. What is the mean absolute deviation of the temperatures?

The mean is -1

Answers

1. Find the mean of the data: (-7 -2 + 1 + 4)/4 = -1

2. Find the absolute value of differences between each data an the mean:

1) |-7 -(-1)| = |-7 + 1| = |-6| = 6
2) |-2-(-1)| = |-2+1| = |-1| = 1
3) |1 -(-1)| = |1+1| = |2| = 2
4) |4 -(-1)| = |4+1|=|5|=5

3) Calculate the mean of those differences:

( 6 + 1 + 2 + 5) / 4 = 14/4 = 3.5

When Malika buys a bicycle she must pay the bicycle's price plus tax.the city sales tax rate is 0.2 times the state sales tax rate. If the state sales tax rate is 0.08,what is the city tax rate? Explain how you found your answer ? Please answer it today tomorrow is school I have to be prepared

Answers

Answer: The city sale tax rate is 0.016

Step-by-step explanation:

Hi, to calculate the city tax rate we simply have to multiply the state sales tax rate (0.08) by 0.2 (because city sales tax rate is 0.2 times the state sales tax rate.)

Mathematically speaking:

0.08 x 0.2 = 0.016

So, the city sale tax rate is 0.016

Feel free to ask for more if needed or if you did not understand something.
0.016 is the city tax I got this by multiplying 0.2 times 0.08
and whenever you multiply smaller number the number go down

There are 169 chairs in the gymnasium that need to be arranged in rows and columns. How can they be divided so that there are an equal amount of rows and columns?

Answers

By arranging the chairs in a 13x13 grid, it can achieve an equal number of rows and columns.

To divide the 169 chairs in the gymnasium into an equal amount of rows and columns, we need to find two factors of 169 that are as close to each other as possible.

The factors of 169 are 1, 13, and 169.

The closest factors are 13 and 13, which means we can arrange the chairs in 13 rows and 13 columns to have an equal amount of chairs in each row and column.

Thus, by arranging the chairs in a 13x13 grid, it can achieve an equal number of rows and columns.
