I think its 2 (not sure though just a guess)
Answer:
37
Step-by-step explanation:
Given :
Sample size, n = 128
Mean, μ = 18
Standard deviation, σ = 5.4
Number of people who lost atleast 15 pounds :
The Zscore = (x - μ) / (σ)
Zscore = (15 - 18) / 5.4
Zscore = - 3 / 5.4
Zscore = - 0.5555
P(Z < - 0.555) = 0.28945
Number of people who lost atleast 15 pounds :
0.28945 * 128 = 37.0496
= 37 people
Answer:
212 m²
Step-by-step explanation:
4 x 4 x 5 = 80
6+6+50+30+40
If 360 is 2/3 of the full price on a saw then your equation should look like this:

x is your unknown full price of the saw. Just solve for x now.

This means that the full price is $540.
Hope this helps!
