(24000-18000)/5=1200
where p is cost, s is sold or salvage value, N is number of years
Answer:
The answer is A
Step-by-step explanation:
64¼ = (2⁶)^¼ so 2^⅔.
Answer:
B maybe
Step-by-step explanation:
Answer:
Step-by-step explanation:
a. Our random variable follows a binomial distribution which is defined as:
where 
is the probability of success, 
the sample size and 
the random variable.
-Given that 
, 
what's 
Hence, the probability of exactly two is 0.2107
b. The probability that more than two adults are more likely to make purchases during a sales tax holiday is given by:
Hence the probability of more that two adult purchases is 0.6727
c. The probability that the number of adults who say they are more likely to make purchases between 2 and 5 is obtain by summing the the probabilities
p(x=2)+p(x=3)+p(x=4)+p(x=5).
-From b above, we already have p(x=2)=0.2107. Therefore:
-Hence the probability of between two and five is 0.8157
You can prove that angle C is 30°. This is because we know that angle B is 120° also, and cointerior angles add to 180°, which makes angle BCF 60°. Then we can divide this by 2 as angle BCF is bisected by AC, so therefore angle ACF is 30° as 60 ÷ 2 = 30.
You can then prove angle A is 90°. First we can find angle BAC because it is part of a triangle, and angles in a triangle add to 180°. This means we can do 30 + 120 = 150, and 180 - 150 = 30° which is angle BAC. Then we do 120 - 30 = 90, as the whole of angle BAF is 120°.
I hope this helps!
