Answer: the probability that exactly 2 buyers would prefer red is 0.0320
Step-by-step explanation:
We would assume a binomial distribution for the color preferences of new car buyers. 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 = 40% = 40/100 = 0.4
q = 1 - p = 1 - 0.4
q = 0.6
n = 14
x = r = 2
Therefore,
P(x = 2) = 14C2 × 0.4^2 × 0.6^(14 - 2)
P(x = 2) = 91 × 0.16 × 0.0022
P(x = 2) = 0.0320

the answer to your question is 6^5
Whoops lol. The answer is 8b³ / c³. Screwed up my work :/
(2b/c)³
= (2bc⁻¹)³
= (2)³ * (b)³ * (c⁻¹)³
= 8b³c⁻³
= 8b³ / c⁻³
Answer:
40.3 feet
Step-by-step explanation:
Use trigonometry.
First, set your calculator to Degrees instead of Radians. Next, draw a model like the attached image to help you better understand the question.
Now, figure out which trigonometric ratio to use. In this case, it is easiest to use sine (or cosine).
sin(38°) = x / 125
125(sin(38°)) = x
x ≈ 37.046
Finally, to find the height, simply add how high the hand is from the ground:
h = 37.046 + 3.25 = 40.296
So,
h ≈ 40.3 ft
