Answer:
a. Blank time = 7:12 am
b. Blank Minutes = 30 minutes
Step-by-step explanation:
The individual got downstairs 25 minutes after 6:47am
Hence Blank time = 6:47am + 25 minutes = 7:12 am
To calculate amount of blank minutes he spent reading books
7:42am - 7:12am = 30 minutes
180-140=40
B is 40 degrees. For further explanation on this answer, do a little research on supplementary angles.
Answer:
The standard error of a proportion p in a sample of size n is given by:
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean and standard deviation , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation .
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean and standard deviation
In this question:
The standard error of a proportion p in a sample of size n is given by:
Answer:
<h2>x=-2 or x=8</h2>
Step-by-step explanation:
Isolate by the x from one side of the equation.
|x-3|=5
x-3=-5 and x-3=5
1. x-3=-5
Add 3 from both sides.
x-3+3=-5+3
Solve.
-5+3=(-2)
x=-2
2. x-3=5
Add 3 from both sides.
x-3+3=5+3
Solve.
5+3=8
x=8
Therefore, the correct answer is x=-2 or x=8.
The answer is 6 i thought it was by looking at it but i did the math just to make sure for you
