The function has a maximum at (1, 3).
_____
You know it is not a minimum because the coefficient of the squared term is negative.
You know the vertex is (1, 3) because you match the pattern to
.. y = a(x -h)^2 +k
which has its vertex at (h, k).
Answer:
<em></em>
<em></em>
<em></em>
Step-by-step explanation:
Given
Required
The standard deviation
First, calculate the expected value E(x)
So, we have:
Next, calculate E(x^2)
So, we have:
The standard deviation is:

Answer:28:53 is M
N is 28:45
Step-by-step explanation:
I’m not fully sure just trying to help
1. u must simplify 3^2 first because the order of operations states that u have to do exponents before subtraction.
2. 12 - 3^2 = 81......she subtracted the 3 first....12 - 3^2 = 9^2 = 81...which is an incorrect answer
3. u do not divide before simplifying 3^2.....order of operations states that u have to do exponents before division
4. no.....(12 - 3)^2 ......order of operations states that u do parenthesis before exponents...so (12 - 3)^2 = 9^2 = 81
Answer: Blue eyes are caused by a recessive allele.
Both parents had a recessive gene for blue eyes, but both parents also had a dominant gene for brown eyes. The two genes for blue eyes happened to meet each other and give the child blue eyes.
Also, put this in the biology section next time.
