Bill buys 3 apples for
$1.47. How much would 10
apples cost Bill?

Answers

Answer:

$4.90

Step-by-step explanation:

bc math

Answer:

$4.90

Step-by-step explanation:

You could find this in the ratio method.

3 apples : $1.47

10 apples : x

( We have to find the value of x. This is the cost of 10 apples)

Cross Multiply both the ratios.

3x = 1.47 × 10

3x = 14.7

Bring 3 to the other side, making is being divided upon.

x = [tex]\frac{14.7}{3}[/tex]

x = 4.9

∴ 10 apples cost $4.90

- The product of [tex]\frac{9}{5}[/tex] and [tex]\sqrt{19 }[/tex] is irrational.

Pi is an irrational number, and the square root of 19 is irrational. That's because these numbers can't be put into a simplified fraction to encompass all the digits it contains.

The list shows the number of minutes that eight students spent on math homework last week. 22, 14, 24, 20, 36, 28, 43, 35What is the mean absolute deviation of the numbers

Answers

Given:

The data values are:

22, 14, 24, 20, 36, 28, 43, 35

To find:

The mean absolute deviation of the given numbers.

Solution:

We have,

22, 14, 24, 20, 36, 28, 43, 35

The measure of the given numbers is:

[tex]\overline{x}=\dfrac{\sum_{i=1}^{n} x_i}{n}[/tex]

Where, [tex]x_i[/tex] represents the observations and n is the number of observation.

So, the mean value of the given data set is:

[tex]\overline{x}=\dfrac{22+14+24+20+36+28+43+35}{8}[/tex]

[tex]\overline{x}=\dfrac{222}{8}[/tex]

[tex]\overline{x}=27.75[/tex]

The formula for is mean absolute deviation is:

[tex]M.A.D.=\dfrac{1}{n}\sum_{i=1}^{n}|x_i-\overline{x}|[/tex]

The mean absolute deviation of the given numbers is:

[tex]M.A.D.=\dfrac{1}{8}[|22-27.75|+|14-27.75|+|24-27.75|+|20-27.75|+|36-27.75|+|28-27.75|+|43-27.75|+|35-27.75|][/tex]

[tex]M.A.D.=\dfrac{1}{8}[5.75+13.75+3.75+7.75+8.25+0.25+15.25+7.25][/tex]

[tex]M.A.D.=\dfrac{1}{8}[62][/tex]

[tex]M.A.D.=7.75[/tex]

Therefore, the mean absolute deviation of the given numbers is 7.75.
