Answer:
152 in³
Step-by-step explanation:
Each cube's volume is the cube of its edge length, so the total volume is ...
(5 in)³ + (3 in)³ = 125 in³ +27 in³ = 152 in³
It is 0. Anything times 0 is 0.
Answer:
np > 10, and n(1 – p) > 10.
Step-by-step explanation:
The normal approximation is used when np>10 and n(1-p)>10.
Here, sample size=n=100 and p=0.42.
So,
np=100*0.42=42>10
n(1-p)=100(1-0.42)=100*0.58=58 >10
As, np>10 and n(1-p)>10 so, the normal distribution can be use to approximate the probability that more than 38 of the sampled people had their most recent eye examination in the previous year.
Answer:
The solutions are t = 0 and t = 1. Since starting time is 0, the arrow is in the air for 1 second.
Step-by-step explanation:
Set the equation equal to zero.
−2t(8t − 8) = 0
Apply the Zero Product Property.
−2t = 0 or 8t − 8 = 0
Solve each equation for t.
t = 0 or 8t = 8
t = 1
