Answer:
17.6621ft²
Step-by-step explanation:
First we need to find the side length of the patio x
SInce the area of the patio = 750
Area of patio = x * x
Area of patio = x²
750 = x²
Swap
x² = 750
x = √750
x = 27.39ft
Length of the backyard = 27.39ft - 25ft = 2.39ft
Width of the backyard = 27.39ft - 20ft = 7.39ft
Area of the backyard = 2.39 * 7.39
Area of the backyard = 17.6621ft²
Answer:
x>3
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
because the are both right triangles
The random sample proportion:
at 90% confidence interval: The Central 90% of any normal distribution is: Z_(α/2) = 1.960
Error = E = ±5% = ±0.05
Applying the normal distribution theory,
= 0.70 ≤ P≤ 0.77(this means that we are 90% confident that the true proportion of jet with wiring problem fall with 0.70 and 0.77, hence there is no need for the airline to conduct further sampling, rather, they should just inspect all the planes)

No, because if it were proportional the cost for 18 bottles of water would be $12
