The answer is 3.
If n^11/n^8=27 then, n^3=27.
The cube root of 27 is 3.
So the answer is 3.

A grid shows the positions of a subway stop and your house. The subway stop is located at (7, -6) and your house is located at (
Yuri [45]

So the distance between subway stop and house is 19 units

Step-by-step explanation:

The distance formula will be used to calculate the distance between home and subway.

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Here (x1,y1) are the coordinates of first point

and

(x2,y2) are the coordinates of second point

Given

(x1,y1) = (7, -6)

(x2,y2) = (-9,5)

Putting the values in the formula

d=\sqrt{(-9-7)^2+(5-(-6))^2} \\=\sqrt{(-16)^2+(5+6)^2} \\=\sqrt{256+(11)^2}\\=\sqrt{256+121}\\=\sqrt{377}\\=19.41\ units

Rounding off to nearest unit gives us 19.

So the distance between subway stop and house is 19 units

A recent survey found that 7575​% of all adults over 50 wear glasses for driving. In a random sample of 4040 adults over​ 50, wh
malfutka [58]

Answer:

Mean = 30

standard Deviation = 2.74

Step-by-step explanation:

Formula

mean = np

Standard Deviation = \sqrt{npq}

from the question = 40

P = 75% or 0.75

q = 1 - p = 1 - 75% or 1 - 0.75

To find mean

mean = 40 x 0.75

           = 30

For Standard Deviation (SD)

Standard Deviation = \sqrt{npq}

       = \sqrt{40 X 0.75 X 0.25

      = \sqrt{7.5}

:. Standard  Deviation       = 2.74

A class of 32 students earned
Yuliya22 [10]

Answer:

5/16 Got a C

Step-by-step explanation:

A = 1/4 x 32

B = (32 - A)/2

D = 2

A = 8

B = (32 - 8)/2

B = 24/2

B = 12

D = 2

8 + 12 + 2 = 22

22/32 did not get a C

32/32 - 22/32 = 10/32

10/32 - > 5/16

What is the end behavior of the function f of x equals negative 4 times the cube root of x?
vampirchik [111]

The function f(x) = 4\sqrt[3]{x} is a cube root function

The function end behavior is:

\quad \mathrm{as}\:x\to \:+\infty \:,\:f\left(x\right)\to \:+\infty \:,\:\:\mathrm{and\:as}\:x\to \:-\infty \:,\:f\left(x\right)\to \:+\infty

<h3>How to determine the end behavior?</h3>

The equation of the function is given as:

f(x) = 4\sqrt[3]{x}

To determine the end behavior, we plot the graph of the function f(x).

From the attached graph of the function, we can see that:

As x approaches infinity, the function f(x) approaches infinity, and vice versa

Hence, the function end behavior is:

\quad \mathrm{as}\:x\to \:+\infty \:,\:f\left(x\right)\to \:+\infty \:,\:\:\mathrm{and\:as}\:x\to \:-\infty \:,\:f\left(x\right)\to \:+\infty
