Please answer question 10

Mathematics
1 answer:
sveta [45]3 years ago
6 0

Answer:

Step-by-step explanation:

1) First, we figure out the number of blue and green marbles (27 each)

2) Subtract the 6 blue and 3 green marbles. We now have 21 blue marbles and 24 green marbles.

3) Since we want to have more blue marbles while taking out the <em>minimum</em> number of green, we're going to take out green marbles out until there's one less than blue. Because there's 21 blue, we want 20 green. We've taken out 4/13 marbles so far.

4) Now, we're going to take 1 marble out of both the greens and blues until we have 17 blue and 16 green. We've now taken out 12/13 marbles. We can't make the 13th marble a blue one, otherwise we even them out, so we'll take another green. Now we have 17 blue and 15 green.

5) Count the number of greens you've taken out, and voila!

6) A cylindrical shaped silo has a diameter of 18 feet and a height of 4 feet. How much water can the silo hold, in terms of π?
Natali5045456 [20]

The amount of water silo can hold in terms of π is 324π cubic feet

<h3><u>Solution:</u></h3>

Given that cylindrical shaped silo has a diameter of 18 feet and a height of 4 feet

To find: Amount of water silo can hold in terms of π

This means we are asked to find the volume of cylindrical shaped silo

<em><u>The volume of cylinder is given as:</u></em>

\text {volume of cylinder }=\pi \mathrm{r}^{2} \mathrm{h}

Where "r" is the radius of cylinder

"h" is the height of cylinder

π is the constant has a value 3.14

Given diameter = 18 feet

radius = \frac{diameter}{2} = \frac{18}{2} = 9

Substituting the values in formula, we get

\text {volume of cylinder }=\pi \times 9^{2} \times 4

\text {volume of cylinder }=\pi \times 81 \times 4=324 \pi

Thus amount of water silo can hold in terms of π is 324π cubic feet

Find the value of x?? Please help!!<br><br><img src="https://tex.z-dn.net/?f=x%20%2B%202%20%3D%20%5Cfrac%7Bx%7D%7B4%7D%20%2B5" i

Answer:

<h2>x = 4</h2>

Step-by-step explanation:

x + 2 =  \frac{x}{4}  + 5

Multiply through by 4 to eliminate the fraction

That's

4x + 8 =  \frac{x}{4}  \times 5 + 5 \times 4 \\ 4x + 8 = x + 20

<u>Subtract x from each side</u>

That's

4x  - x + 8 = x - x + 20 \\ 3x  + 8 = 20

<u>Subtract 8 from each side</u>

3x + 8 - 8 = 20 - 8 \\ 3x = 12

<u>Divide both sides by 3</u>

\frac{3x}{3}  =  \frac{12}{3}

We have the final answer as

<h3>x = 4</h3>

Hope this helps you

American households increasingly rely on cell phones as their exclusive telephone service. It is reported that 50.4% of American
OLga [1]

The variance of the binomial distribution of the number of households with landline service is 2.

<h3>What is the binomial probability distribution?</h3>

It is the probability of <u>exactly x successes on n repeated trials, with p probability</u> of a success on each trial.

The variance of the distribution is given by:

V(X) = np(1 - p)

In this problem, the parameters are given as follows:

n = 8, p = 0.504.

Hence the variance is given by:

V(X) = 8 x 0.504 x 0.496 = 2.
