Answer:
0.12
Step-by-step explanation:
Independent events are when probability of one event happening doesn't affect the probability of the other event happening.
Also,
In probability "AND" means "multiplication" and "OR" means "addition".
The question asks for probability that Nick oversleeps "AND" has pop quiz. So we need to multiply the individual probabilities (since independent, they have no affect on each other).
P(Nick oversleeps) = 0.48
P(pop quiz) = 0.25
Thus,
P(Nick oversleeps AND pop quiz) = 0.48 * 0.25 = 0.12
Answer:
A
Step-by-step explanation:
Using the cosine ratio in the right triangle
cosA = 
= 
= 
, thus
A = 
( ) ≈ 48° → A
Jacob=5 5/6 ft
Linda=5 1/4
So to find out the difference, we first have to make the fractions equivalent.
5/6x2/3=10/12
1/4x3/3=3/12
Now we subtract.
5 10/12-5 3/12
=7/12
Jacob is 7/12 ft taller than Linda.
