Answer:

Kindly check explanation

Step-by-step explanation:

Given the data on the result of math exam in Ben's class

{35,42,56,68,69,72,72,77,78,78,82,85,87,88,90,93,94,96,96,99}

The 85th percentile score represents the score in which 85 percent of the students in Ben's class or below obtained in the test.

The 85th percentile score :

85%(n+ 1) term

n = number of observations = 20

0.85(20 + 1)th term

0.85(21) = 17.85 term

Take the average of the 17th and 18th terms

(94 + 96) / 2

= 190 / 2

= 95

I need to know what the volume of the cone in cubic inches please
ivolga24 [154]

Answer:

V = 118 in³

Step-by-step explanation:

The volume of a cone of radius r and height h is V = (1/3)(π)(r^2)(h).

In this case, the volume is V = (1/3)π(3 in)^2·(6 in), or π(18 in³)

Using 3.14 as the approximate value of π, we get V = 118 in³

Syrus is buying a tent with the dimensions shown below. The volume inside the tent is 363636 feet^3 3 cubed. Syrus isn't sure if
stealth61 [152]

Answer:

The height of the tent = 3 feet

Step-by-step explanation:

Question

Syrus is buying a tent with the dimensions shown below. The volume inside the tent is 36 feet^3. Syrus isn't sure if the tent will be tall enough for him to sit up inside. The tent is the shape of triangular prism whose length is 6 feet and width is 4 feet. What is the height of the tent?

Given:

Length of the tent = 6 feet

Width of the tent = 4 feet

Volume of the tent = 36 feet^3

To find the height of the tent.

Solution:

Since the ten is in shape of triangular prism, so the volume of traingular prism is given as:

V=\frac{1}{2}\times l\times w\times h

where l represents length, w represents width and h represents height of the prism.

Plugging in the know values of the dimension of the tent and the volume to find the height of the tent.

36=\frac{1}{2}\times 6\times 4\times h

Simplifying.

36=12h

Dividing both sides by 12.

\frac{36}{12}=\frac{12h}{12}

3=h

∴ h=3

Thus, the height of the tent = 3 feet

If f(x)=3^x+10x and g(x)=4x-2, find (f+g)(x)
Vikentia [17]
Hi there!

First we need to remember the following.
(f + g)(x) = f(x) + g(x)

Now substitute both of the formulas.
(f + g)(x) = ({3}^{x} + 10x)+ (4x - 2)

Work out the parenthesis.
(f + g)(x) = {3}^{x} + 10x + 4x - 2

And finally collect terms.
(f + g)(x) = {3}^{x} + 14x - 2

~ Hope this helps you!

Find the slope of the line that passes through (-20, -51) and (31, -75).
lilavasa [31]

Answer:

-8/17

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-75-(-51))/(31-(-20))

m=(-75+51)/(31+20)

m=-24/51

m=-8/17
