Answer:
if a z-score is equal to +1, it is 1 standard deviation above the mean.
Step-by-step explanation:
7/10 is bigger because it is more than half
Given:
Consider the below figure attached with this question.
To find:
The value of 
.
Solution:
The given functions are:
Now,
We know that,
Adding 3 on both sides, we get
So, for all values of x.
Hence, the correct option is A.
It depends on the question, but if the question is, how many is there....
It usually means to <u><em>add</em></u>
(What is the question anyway?)
Answer:
Simplest polynomial: x²+x-12
Step-by-step explanation:
zeroes of polynomial= 3,-4
Therefore,
f(3) =0
f(-4)=0.
By factor Theorem
(x-3) and (x+4) are factors
so simplest polynomial is
(x-3)(x+4)
= x² - 3x + 4x -12
= x² + x -12
.
Hope it helps
