Answer:
0.57926
Step-by-step explanation:
We have been given that the capacity of an elevator is 15 people or 2385 pounds. The people have weights that are normally distributed with a mean of 165 lb and a standard deviation of 30 lb. We are asked to find the probability that a randomly selected person has a weight greater than 159 pounds.
First of all, we will find z-score corresponding to 159 using z-score formula.
Now, we need to find area under normal distribution curve that is greater than z-score of as:
Using formula , we will get:
Therefore, the probability that if a person is randomly selected, his weight will be greater than 159 pounds, is 0.57926.
Answer:
to understand this we will turn 5 5/6 into a inproper fraction 5 can be turned into 60/12 and 5/6 can be turned into 10/12 so this is equal to 70/12.
5 5/6=70/12
in 70 there are 14 pairs of 5's, 14x5=70
this means that he will need 14 telephone pole's
slope intercept form is y = mx+ b
lets get the equation in that form
8y = 2x+4
divide each side by 8
8y/8 = 2x/8 + 4/8
y = 1/4x + 1/2
the slope or m is 1/4
Choice C
The correct answer is option C which is 230p – 1010 = 650p – 400 – p this expression is same as of 2.3p – 10.1 = 6.5p – 4 – 0.01p.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given expression:-
2.3p – 10.1 = 6.5p – 4 – 0.01p
The same expression will be calculated as:-
Multiply the given expression by 100 we will get our answer.
E = 100 (s 2.3p – 10.1 = 6.5p – 4 – 0.01p )
E = 230p – 1010 = 650p – 400 – p
Therefore the correct answer is option C which is 230p – 1010 = 650p – 400 – p this expression is same as of 2.3p – 10.1 = 6.5p – 4 – 0.01p.

Really simple. Divide by 2 then add and subtract 9
68/2 = 34
34 + 9 = 43
34 - 9 = 25
43 - 25 = 18
The two numbers are 43 and 25
