Inside a gallon is 4 quarts so then multiply 2 for every pint/quart then multiply 2 for every cup/pint which gets you to 16 cups. That's probably really confusing. Sorry.
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
Answer:
12x^2-2x-5
Step-by-step explanation:
(9x2 + 3x - 2) + (3x2 - 5x - 3)
Combine like terms
9x^2+3x^2+3x-5x-2-3
12x^2-2x-5
The area of the shape is 150ft.
I don't have time to explain it right now sorry!
Hope this helps <3
