Answer:
The mean of the combined math and verbal scores is 1100, while the standard deviation is 141.
Step-by-step explanation:
Normal variables
Normal variables have mean 
and standard deviation 
When we add normal variables, the combined mean is the sum of both means, and the standard deviation is the square root of the sum of both variances. The distribution is still normal.
In this question:
Verbal: 
.
Math: 
Combined:
The mean of the combined math and verbal scores is 1100, while the standard deviation is 141.
Answer:
by the distance formula
the points are (2,2) and (-2,7)
and subtituting d=sqrt((2-(-2))^2+(2-7)^2)
which is equal to sqrt of 41
and it is equal to 6.40
Answer:
A
Step-by-step explanation:
We need to find a equation that is where the domain is all real numbers and the range is all real numbers greater than -3
- A square root function cannot equal to all real numbers because we cant take the square root of a negative number. so B and C are already wrong.
- A cubic function range is all real numbers. so y can be greater than -3 but it would also include. values lesser than -3. so D is Wrong.
A is right, the domain of a absolute value function is all real numbers. The range of a absolute value is all numbers greater than or equal to zero but if we subtract 3, it changes into all real numbers greater than or equal to -3
