Answer:
(a) 93.19%
(b) 267.3
Step-by-step explanation:
The population mean and standard deviation are given as 502 and 116 respectively.
Consider, <em>X</em> be the random variable that shows the SAT critical reading score is normally distributed.
(a) The percent of the SAT verbal scores are less than 675 can be calculated as:
Thus, the required percentage is 93.19%
(b)
The number of SAT verbal scores that are expected to be greater than 575 can be calculated as:
So,
Out of 1000 randomly selected SAT verbal scores, 1000(0.2673) = 267.3 are expected to have greater than 575.

We have to find the domain of the given function
"The domain of a function is the set of input or argument values for which the function is real and defined"
Now, we have to find the values of 'x' for which the given function will be real and defined.
As we can observe that for any real number, the given function will be real and defined.
Therefore, the domain of the given function is or
.
Or we can say that the domain of the given function is the set of all real numbers.
Its obviously A
Hope this helped :)
Step-by-step explanation:
divide both sides by -8
remember if you multiply or divide by a negative the sign flips
x<8
