Answer:

$559\frac{1}{5}$

Step-by-step explanation:

We want to determine the exact value that is 48% of 1165.

Now 48% = $\frac{48}{100}$

The term 'OF' means multiplication.

Therefore:

48% of 1165 = $\frac{48}{100}X 1165$

= $\frac{55920}{100}$

= $559\frac{1}{5}$

=559.2 in decimal form.

The exact value that is 48% of 1165

is given as $559\frac{1}{5}$ or 559.2 in decimal form.

Three answer choices have the same quotient as 4.55 ÷ 0.7. Which one does NOT

Answer:

Answer: 455 / 7

Step-by-step explanation: Three answer choices have the same quotient as 4.55 ÷ 0.7. Which one does NOT?

answer choices

455 ÷ 70

455 ÷ 7

45.5 ÷ 7

4.55 ÷ 0.70

The number resulting from the division of one number by another is regarded as quotient. For example, The quotient of 12 divided by 4 is 3.

And so, the first, third and last options on expansion by division all yield the same results in decimals (6.5) as that in the question (4.55 / 0.7 = 6.5) which is an indication that they have the same quotient.

Only the second option does not do so. 455 / 70 = 65

What is the mean absolute deviation?

Lostsunrise [7]

Answer:

0.8 cm

Step-by-step explanation:

The formula for MAD is attached in the picture.

x_i are the values (data)

x bar is the mean

n is the number of numbers (data)

For figuring out MAD, basically, <em>we subtract the mean from each of the values respectively and take the absolute value and SUM for all of the numbers in the data set. Then we divide by n, the number of numbers.</em>

<em />

Let's do this:

MAD = $\frac{|2-3|+|2-3|+|2-3|+|2-3|+|3-3|+|3-3|+|3-3|+|4-3|+|4-3|+|5-3|}{10}\\=\frac{1+1+1+1+0+0+0+1+1+2}{10}\\=\frac{8}{10}=0.8$
