Answer:
Mean- 6
MAD- 1.73...

Explanation:
Mean- I added all the dots together then divided by 15.
MAD- For the mean I got 6 so I subtracted the difference of each dot from 6, added them all up, and divided them by 15.

Mode: 5,7

Median: 6

Range: 13 - 2 = 11

IQR (interquartile Range): 7 - 5 = 2

Mean: 6

M.A.D (Mean Absolute Deviation): 1.73

________________________________

( how I found the mean )

2 x 1 = 2

3 x 1 = 3

4 x 1 = 4

4 x 5 = 20

6 x 2 = 12

4 x 7 = 28

8 x 1 = 8

13 x 1 = 13

________________________________

2 + 3 + 4 + 20 + 12 + 28 + 8 + 13 = 90/15 = 6!

mean = 6!

____________________________________

(finding the M.A.D mean absolute deviation)

6 - 2 = 4

6 - 3 = 3

6 - 4 = 2

6 - 5 = 1

6 - 6 = 0

6 - 7 = 1

6 - 8 = 2

6 - 13 = 7

_____________________________

1 x 4 = 4

_____________________________

4 + 3 + 2 + 4 + 4 + 2 + 7 = 26/15 = 1.73

so the answer to your question should be 1.73!

What is the value of x in the figure below? In this diagram, △ABD~△CAD.

morpeh [17]

Given:

Given that the triangles ABD and CAD are similar.

The length of AB is 12.

The length of BD is x.

The length of AC is 27.

We need to determine the value of x.

Value of x:

Let us use the leg rule to determine the value of x.

Thus, we have;

$\frac{BC}{AB}=\frac{AB}{BD}$

Substituting the values, we get;

$\frac{27}{12}=\frac{12}{x}$

Cross multiplying, we get;

$27x=12\times 12$

$27x=144$

Dividing both sides by 27, we have;

$x=\frac{16}{3}$

Thus, the value of x is $\frac{16}{3}$

Hence, Option D is the correct answer.

Find the range of the following equation for the domain {-4, 0, 3} f (x) = -2x^2 -3

Tamiku [17]

The range of the function is {-34, -2, -20}

<h3>How to determine the range?</h3>

The function is given as:

f(x) = -2x^2 - 2

The domain is {-4, 0, 3}

Substitute the domain values in the function.

f(-4) = -2(-4)^2 - 2 = -34

f(0) = -2(0)^2 - 2 = -2

f(3) = -2(3)^2 - 2 = -20

This means that the range of the function is {-34, -2, -20}

Which point would be a solution to the system of linear inequalities ?

brilliants [131]

Answer:

(12,-6)

Step-by-step explanation:

we have

$y\leq \frac{4}{3}x+5$ ----> inequality A

$y\geq -\frac{5}{2}x+5$ ---> inequality B

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (makes true both inequalities)

Verify each point

Substitute the value of x and the value of y of each ordered pair in the inequality A and in the inequality B

case 1) (0,-1)

Inequality A

$-1\leq \frac{4}{3}(0)+5$

$-1\leq5$ ----> is true

Inequality B

$-1\geq -\frac{5}{2}(0)+5$

$-1\geq 5$ ----> is not true

therefore

The ordered pair is not a solution of the system

case 2) (0,3)

Inequality A

$3\leq \frac{4}{3}(0)+5$

$3\leq5$ ----> is true

Inequality B

$3\geq -\frac{5}{2}(0)+5$

$3\geq 5$ ----> is not true

therefore

The ordered pair is not a solution of the system

case 3) (-6,-6)

Inequality A

$-6\leq \frac{4}{3}(-6)+5$

$-6\leq-3$ ----> is true

Inequality B

$-6\geq -\frac{5}{2}(-6)+5$

$-6\geq 20$ ----> is not true

therefore

The ordered pair is not a solution of the system

case 4) (12,-6)

Inequality A

$-6\leq \frac{4}{3}(12)+5$

$-6\leq21$ ----> is true

Inequality B

$-6\geq -\frac{5}{2}(12)+5$

$-6\geq -25$ ----> is true

therefore

The ordered pair is a solution of the system (makes true both inequalities)

Hello everyone, I hope you had a great day, I need help on this please, thanks.

Shalnov [3]

Answer:

Step-by-step explanation:

A. is the only correct solution to this question because you can also see that if we take 8 and divide this by 32 we get 1/4, so we know it is true.

Divide 33 photos into two groups so the ratio is 4 to 7

jeka57 [31]

33 photos in a 4x to 7x ratio

4x + 7x = 33
11x = 33
x = 3

33 photos can be put in a 4(3) to 7(3) ratio

which is a 12 to 21 ratio

so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7

Note:
a(b) = ab = a x b = a times b
