A fraction you are dividing while a decimal is considered as a number
Answer:
a. 42 x 39 = 1638 ft²
b. small = 12(large)
small = 12(48)
= 576
576 - 48 = 528 more small posters
The answer is A.
y = x^2 + 2 simply means that y is whatever x is to the second power, plus 2. so, -2^2 = 4. 4 + 2 = 6.
you can work this through the other options but A is the answer.
Answer:
the answer is twenty percent
Step-by-step explanation:
the word *reduce* was a give away of subtraction so you subtract 60 from 80 which gives you 20.
Given:
z = (x - μ)/σ = z value
x = independent variable = 11
μ = mean = 8
σ = standard deviation = 3
Solution:
X ~ N (8, 3)
For day 1, n = 5
P (X < = 11) = P (Z < = 11 – 8 / 3/Sqrt5) = P (Z <
=2.23) = 0.987126
For day 1, n = 6
P (X < = 11) = P (Z < = 11 – 8 / 3/sqrt6) = P (Z <
=2.45) = 0.992857
For both days:
P (X <= 11) = P (X <= 11) = (0.987126) (0.992857) =
0.9801
