The event that represents a "success" is (a) US adults who feel the American dream is out of reach

<h3>How to determine the success event?</h3>

From the question, we have:

p = 11%

The variable represents the proportion of US adults that feel the American dream is out of reach.

This represents the probability of success.

Hence, the event that represents a "success" is (a) US adults who feel the American dream is out of reach

<h3>Why is x a binomial random variable?</h3>

A binomial random variable can only take any two values

This means that x is a binomial random variable because (b) there are only two possible outcomes.

<h3>The value of p for the binomial event</h3>

In (a), we have:

p = 11%

Hence, the value of p for the binomial event is 11%

For the senior pic mr. Williams is using two cylinders to help keep the food cool the inside still there with the radius of 8 in

Rasek [7]

The answer is 1,695.6 in³.

The volume of the empty space is the difference of the bigger cylinder and the smaller cylinder: V = V1 - V2

The volume of the bigger cylinder is:
V1 = π r² h
r = 10 in
h = 15 in
π = 3.14

V1 = 3.14 * 10² * 15 = 4,710 in³

The volume of the smaller cylinder is:
V2 = π r² h
r = 8 in
h = 15 in
π = 3.14

V2 = 3.14 * 8² * 15 = 3,014.4 in³

The volume of the empty space is:
V = V1 - V2 = 4,710 in³ - 3,014.4 in³ = 1,695.6 in³

I need the equation for this ASAP!

Sindrei [870]

Answer:

5.714 liters of the 5% solution and 4.286 of the 40%.

Step-by-step explanation:

Let x be the volume of 40% solution and y = volume of the 5% solution.

x + y = 10

0.40x + 0.05y = 0.20(x + y)

From the first equation x = 10 -y so we have:

0.40(10 - y) + 0.05y = 0.20( 10 - y + y)

4 - 0.40y + 0.05y = 2

-0.35y = -2

y = 5.714 liters of the 5%.

and x = 10 - 5.714 = 4.286 liters of the 40% solution.
