Answer:

32

Step-by-step

to find mean you add all the values and then divide them by the number of values their so for this question you would add 11+16+70+66+14+15=192 then divided it by the number of values which is 6 so 192/6=32

I hope this helps you

The shaded region's area is x² + 23x + 49.

Step-by-step explanation:

Step 1; To calculate the area of the shaded region, we subtract the area of the square which has side lengths of (x + 1) from the entire rectangle. So we determine the equations that denote the areas of the two shapes.

Step 2; Area of the square = side length × side length (x + 1)×(x + 1)    = x² + x + x + 1 = x² + 2x + 1

Area of the bigger rectangle = length × breadth = (x + 10) × (2x + 5)                            = 2x² + 5x + 20x + 50 = 2x² + 25x + 50.

Step 3; The given shaded region's area = Area of the bigger rectangle - Area of the smaller square = 2x² - x² + 25x - 2x + 50 - 1                          = x² + 23x + 49.

So the shaded region's area of x² + 23x + 49.

Vedmedyk [2.9K]


[4^(5/4+1/4)]^1/2

= --------------------------

4^(1/2 * 1/2)


[4^(6/4)]^1/2

= ----------------------

4^(1/4)


4^(3/2 * 1/2)

= ----------------------

4^(1/4)


4^(3/4)

= ---------------

4^(1/4)


= 4^(3/4 - 1/4)

= 4^2/4

= 4^1/2

= √4

What is the slope of the line that passes through points (-3,5) and (11,5)<br>​
Lerok [7]

Answer:

slope = -3/14

Step-by-step explanation:

y1  - y2 / x1 - x2

They gave you one value, two total coordinates

5-5 = 1

-3 - 11

-14

1/-14

y=1/-14 + b

11= 1/-14(-3) + b

11 = -3/14 + b

17 + 14

b = 15 3/14

Find the values X and Y if L ll M .
Naddik [55]

Let's solve for x first.

To find x, use the interior angles on same side of a transversal theorem.

The interior angles on sam side of a transversal are supplemantary angles, and supplementary angles sum up to 180 degrees.

Thus, we have:

(23x - 16) + (8x - 21) = 180

23x - 16 + 8x - 21 = 180

Combine like terms:

23x + 8x - 21 - 16 = 180

31x - 37 = 180

Add 37 to both sides:

31x - 37 + 37 = 180 + 37

31x = 217

Divide both sides by 31:

\begin{gathered} \frac{31x}{31}=\frac{217}{31} \\  \\ x\text{ = 7} \end{gathered}

To find y, use the vertical angles theorem.

Vertical angles are congruent.

Thus we have:

7y - 23 = 23x - 16

Since x = 7, substitute x for 7 in the equation above to find y.

7y - 23 = 23(7) - 16

7y - 23 = 161 - 16

7y - 23 = 145

Add 23 to both sides:

7y - 23 + 23 = 145 + 23

7y = 168

Divide both sides by 7:

\begin{gathered} \frac{7y}{7}=\frac{168}{7} \\  \\ y\text{ = }24 \end{gathered}

x = 7

y = 24

ANSWER:

x = 7

y = 24
