Step-by-step explanation:
4x²-64
(2x)²-(8)²
a²-b²=(a+b)(a-b)
=(2x+8)(2x-8)
Therefore, the factors are -4 and 4.
P(x ≥ 0.75) = P(z ≥ (0.75 - 0.45)/0.40) = P(z ≥ 0.30/0.40) = P(z ≥ 0.75) = 1 - P(z < 0.75) = 1 - 0.077337 = 0.22663
Hi. The difference between terminating decimals and different from repeating decimals is:
Terminating decimals is a decimal that ends. It is a decimal with an infinite number of digits.
Repeating decimals have a digit or a block of digits that repeat over and over again.
Hope this helps.
Take care,
Diana
A....... The mean can't be 30 because normally, the mean is lower than the highest number in your data....
B.......... There are 5 numbers, and 15 is the 2nd highest number..... so no it can't be the median
Answer:
see explanation
Step-by-step explanation:
(a)
Consider the denominator
To obtain 5xy from x , multiply by 5y
Thus numerator is multiplied by 5y, that is
= 
(b)
Consider the numerator
To obtain 5ab² from ab, multiply by 5b
Thus denominator is multiplied by 5b, that is
=
