Answer:
(1/2) cm = x
Step-by-step explanation:
This box has the shape of a cube. The formula for the volume of a cube is V = x^3, where x is the length of any one side of the cube.
Here the volume is (1/8) cm^3. We set this equal to x^3 and solve for x:
Taking the cube root of both sides, we get:
(1/2) cm = x
Answer:
60°
Step-by-step explanation:
angle A +angle B +angle C = 180
30° +B+90°= 180
120°+B=180°
B=180°-120°
B=60°
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)
