Answer:
I believe it's the third and fourth answers.
Step-by-step explanation:
Answer:
If x can only have one answer, then the solution is one value. If x can be all real numbers, then the solution is all real numbers. And if x doesn't have an answer then it has no solution.
Step-by-step explanation:
For example:
One value: 7 + x= 10 => x= 3
All real numbers: 0x=0 => x can be all real numbers
No solutions: 7x=6x => no solutions
Answer:
0.015 is the approximate probability that the mean salary of the 100 players was less than $3.0 million
Step-by-step explanation:
We are given the following information in the question:
Mean, μ =$3.26 million
Standard Deviation, σ = $1.2 million 100
We assume that the distribution of salaries is a bell shaped distribution that is a normal distribution.
Formula:

Standard error due to sampling =

P(mean salary of the 100 players was less than $3.0 million)
Calculating the value from the standard normal table we have,

0.015 is the approximate probability that the mean salary of the 100 players was less than $3.0 million
Answer:
B. (-4-2)
Step-by-step explanation:
since the numerator is one you can divide -8 by the denominator of each fraction. -8/2 = -4, -8/4 = -2
(-4-2)
You have to make sure you distribute the -8 to all parts inside the parenthesis for it to be right.
i hope this helps :)
Answer:
In 10 weeks he saved: 87.8-37.8= $50
so each week he saves 50/10= $5
Step-by-step explanation:
So every week he earns 5*100 / 20= $25
