Answer:
$3
Step-by-step explanation:
3 dollars because
1 pound = 16 ounces
and 1 pound costs 1.5 dollars
if there are 32 ounces of broccoli, you divide the number of ounces by 16 and multiply that by 1.5
32/16 = 2 x 1.5 = 3
Answer:
No
Step-by-step explanation:
For this triangle to be a right triangle the following has to happen:
a^2 + b^2 = c^2
a=3, b=9, c= 12
3^2+9^2 does not equal 12^2
9+81 = 90 12^2 = 144
90 does not equal 144 so is not a right triangle
Eight times fifty one is 408

Answer:
Step-by-step explanation:
Let μ - mean, σ - standard deviation.
<h3>Given:</h3>
A score of 30 falls three standard deviations below the mean:
A score of 60 falls three standard deviations above the mean:
Add up the two expressions and find the value of μ:
- μ - 3σ + μ + 3σ = 30 + 60
- 2μ = 90
- μ = 45
The mean is 45
