Answer:

1-reciprocal of 11/7=7/11

2-if the denominator is negative multiply it with -1

7/-11*-1= -7/11

Step-by-step explanation:

32-20 = 12

14-2 = 12

so the input is 12 more than the output

so 6+12 = 18

and

-10-12 = -22

The table below shows the number of cups of coffee people drink a day

Effectus [21]

The mean of a distribution is the sum of the data elements divided by the count of the dataset.

The mean of the distribution is 4

The complete table is given as

$\left[\begin{array}{cc}People & Frequency &0 - 2 & 5 & 3 - 5 & 25 & 6 - 8 & 5\end{array}\right]$

The complete question requires that, we calculate the mean of the dataset

First, we calculate the class midpoint

This is the average of the class interval

For interval 0 - 2,

$x_1 = \frac{0 + 2}{2} = 1$

For interval 3 - 5,

$x_2 = \frac{3 + 5}{2} = 4$

For interval 6 - 8

$x_3 = \frac{6 + 8}{2} = 7$

So, the table becomes

$\left[\begin{array}{ccc}People & x & Frequency &0 - 2 &1 & 5 & 3 - 5 & 4& 25 & 6 - 8& 7 & 5\end{array}\right]$

The mean is then calculated as:

$\bar x = \frac{\sum fx}{\sum f }$

This gives

$\bar x = \frac{5 \times 1 + 25 \times 4 + 5 \times 7}{5 + 25 + 5}$

$\bar x = \frac{140}{35}$

$\bar x = 4$

Hence, the mean of the distribution is 4

You are searching for two integers. The sum of twice the first integer and three times the second integer is nine. At the same t

devlian [24]

Answer: -3 and 5

Step-by-step explanation:

Let x represent the 1st digit and y represent the 2nd digit. Then,

Eq 1: 2x + 3y = 9 → 3(2x + 3y = 9) → 6x + 9y = 27

Eq 2: 3x + 2y = 1 → -2(3x + 2y = 1) → -6x - 4y = -2

5y = 25

y = 5

Substitute y = 5 into either of the original equations to solve for x:

2x + 3y = 9

2x + 3(5) = 9

2x + 15 = 9

2x = -6

x = -3

Check (using the other original equation):

3x + 2y = 1

3(-3) + 2(5) = 1

-9 + 10 = 1

-1 = 1 $\checkmark$
