Answer:
The elm tree is 40 5/6 inches tall
Step-by-step explanation:
Let
Tallness of the apple tree = x
Tallness of the elm tree= 3 1/2x
Apple tree = 10 2/3 feet tall
Elm tree = 3 1/2x
Where x= 10 2/3
Elm = 3 1/2 (10 2/3)
= 7/2(35/3)
= 7*35 / 2*3
= 245 / 6
= 40 5/6 inches tall
The elm tree is 40 5/6 inches tall
Answer: P(x ≥ 1) = 0.893
Step-by-step explanation:
We would assume a binomial distribution for the outcome of the investment. The formula is expressed as
P(x = r) = nCr × p^r × q^(n - r)
Where
x represent the number of successes.
p represents the probability of success.
q = (1 - r) represents the probability of failure.
n represents the number of trials or sample.
From the information given,
p = 36% = 36/100 = 0.36
q = 1 - p = 1 - 0.36
q = 0.64
n = 5
Therefore,
P(x ≥ 1) = 1 - P(x = 0)
P(x = 0) = 5C0 × 0.36^0 × 0.64^(5 - 0)
P(x = 0) = 1 × 1 × 0.107
P(x = 0) = 0.107
P(x ≥ 1) = 1 - 0.107 = 0.893

Step-by-step explanation:
Answer:
41.79%
Step-by-step explanation:
To be on the swim team, we look at the right most (total) number int he table of "on the swim team" row. That is 28.
The grand total is the bottom-rightmost. That is 67.
Hence, probability of being on swim team is 28/67 = 41.79%
