Answer:
7
Step-by-step explanation:
Let the height of pyramid be h

v= 224
w= 8
l= 12
224=1/3(12)(8)(h)
224=32h
h=224/32
h=7
Answer:
no solution
Step-by-step explanation:
Answer:
d. is the sum of the probabilities of the sample points in the event.
Step-by-step explanation:
Suppose we have a fair coin then the the sample space S is given by {(H), (T)}
the head and tail are the sample points.
the probability of sample space will be given by the sum of probability of head and tail. P(S)= P(A) + P(B)
1= 1/2+ 1/2
The total probability of the sample space always equals 1
The individual probabilities add up to to give the probability of the sample space.
Answer:
The standard deviation is 0.1104. The 10% condition is met because it is very likely there are more than 200 minnows in the pond.
Step-by-step explanation:
The standard deviation for a proportion is:
σ = √(pq/n)
where p is the proportion, q is 1−p, and n is the sample size.
σ = √(0.58 × 0.42 / 20)
σ = 0.1104
Since the pond is large, there's probably more than 200 minnows, so the 10% condition is met.
