Both of those times are in two standard deviations, so the percent would be 95%.
Answer:
x^2 +20x+100
Step-by-step explanation:
(x+10)^2
(x+10) (x+10)
FOIL
first:x*x = x^2
outer: x*10
Inner 10*x
last: 10*10 =100
Add them together
x^2+10x+10x+100
x^2 +20x+100
Answer
a = √b or -√b
Step by step explanation
The square root property :
If x^2 = c, then x = √c or x = -√c
According to the property, we get
a^2 = b,
a = √b or -√b
Thank you.
182.886
^ Hundredth's place
The number after that is 6, so we round up.
Add 1 to the hundredth's place.
8 + 1 = 9
That gives us:
182.89
To solve the equation, we can first collect like terms to make the process easier.
4n-11=9 -> +11 on both sides -> 4n=20
Now, we can see that 4 n's make 20, so we can work backwards to solve for n:
4n=20 -> ÷4 on both sides -> n=5
So, your answer is B - 5.
