The director of admissions at Kinzua University in Nova Scotia estimated the distribution of student admissions for the fall sem

svlad2 [7]

Answer:

The expected number of admissions for the fall semester is approximately 1248 students.

Step-by-step explanation:

We are given the following information in the question:

Number of Students: 1,060 1,400 1,540

Probability: 0.61 0.11 0.3

Formula:

$\text{Expectation} = E(x) = \sum xP(x)$

Expected number of admissions for the fall semester =

$E(x) = \sum xP(x)\\= (1060\times 0.61) + (1400\times 0.1) + (1540\times 0.3)\\=1248.6$

Hence, the expected number of admissions for the fall semester is approximately 1,248 students.

BOXES A cardboard box company designs all of its boxes so that they have a depth of n, a height of 2n+1, and a width of 3n+2.

The volume of the box made by cardboard box company which has a depth of n, a height of 2n+1, and a width of 3n+2, is 6n³+7n²+2n

<h3>What is of volume of rectangular prism?</h3>

Volume of rectangular prism is the amount of quantity, which is obtained in it in the 3 dimensional space.

Volume of a rectangular prism is the product of its width, height and length.

V=w×h×l

Here, (w) is the width of the base (l) is the length and (h) is the height of the rectangular prism.

A cardboard box company designs all of its boxes suc that they have the measure of depth of n, a height of 2n+1, and the measure of width of 3n+2.Thus, the volume of this box is,

V=w×h×l

V=(3n+2)×(2n+1)×(n)

V=(3n+2)×(2n²+n)

V=6n³+3n²+4n²+2n

V=6n³+7n²+2n

Thus, the volume of the box made by cardboard box company which has a depth of n, a height of 2n+1, and a width of 3n+2, is 6n³+7n²+2n

Help, help, help! Quick Answer, please!

gregori [183]

Answer:

3. 102

4. c

Step-by-step explanation:

For number 3:

(c^2 - a) + b becomes (10^2 - 3) + 5

10^2 = 100

100 - 3 + 5 = 102

For number 4:

Usually when you see distributive property, you're multiplying into parentheses. This time you're factoring out.

20c - 8d

It's not a, because that would be 20c + 8d

It's not b, because that would be 20c -32d

It is c, because 4 x 5c = 20 c and 4 x -2d = -8d

It's not d, because that would be 20c- 8cd
