The distribution of total body protein in healthy adult men is approximately Normal with mean 12.3 kg and standard deviation 0.1
Gelneren [198K]

Answer: a. 0.9876

Step-by-step explanation:

Given : The distribution of total body protein in healthy adult men is approximately Normal with mean 12.3 kg and standard deviation 0.1 kg.

\mu=12.3 and \sigma=0.1

sample size : n= 25

Let x denotes the  total body protein in healthy adult men in the sample.

Then, the probability that their average total body protein is between 12.25 and 12.35 kg will be :-

P(12.25

∴ The correct answer is a. 0.9876

If x^(3/5) = 1.84, then x^2 = ?<br> Show Work.<br> A.) 7.63<br> B.) 10.40<br> C.) 21.15
svetlana [45]
X^(3/5) = 1.84

x^(3/5) = (1.84)

Raise both sides of the equation to (5/3).  

This is so that on the side with x,  3/5 * 5/3 = 1.

(x^3/5 )^5/3 = (1.84)^(5/3)

x^(3/5  *  5/3) = 1.84^(5/3)

x^1 = 1.84^(5/3)
 
x = 1.84^(5/3)

But remember we are solving for x^2.

x = 1.84^(5/3)

x^2 = (1.84^(5/3))^2

x^2 =  1.84^(5/3  *2 )

x^2 =  1.84^(10/3)

Use a calculator here.

x^2 =  1.84^(10/3) ≈ 7.63

Option A.

Cheers!

An art teacher has a jar containing b buttons to distribute to her class for a project. In order to give each in the class 6 but
Nastasia [14]

Answer:

22

Step-by-step explanation:

Given:

An art teacher has the total number of buttons = b

1. In order to give each in the class 6 buttons, she will need 18 more buttons.

2. If she gives each child 5 buttons, she will have 4 left over.

Question asked:

How many children are in the class ?

Solution:

<u>Let total number of children in the class = </u>x

<u><em>As given that, 18 more buttons will be needed to give 6 buttons to each.</em></u>

The equation will be:-

b+18=6x\\b-6x=-18\ (equation\ 1)

<em><u>Also given that, If she gives 5 buttons to each, she will have 4 left over.</u></em>

The equation will be:-

b-5x=4\ (equation\ 2)

Subtraction equation 2 from 1

b-6x-(b-5x)=-18-4\\b-6x-b+5x=-22\\-6x+5x=-22\\-x=-22\\Minus\ canceled\ by\ minus\\x=22

Hence, total number of children are 22.
