Answer:

$1840.00

Step-by-step explanation:

The answer is 1840.00 because the formula for a trapezoid is A=a+b

divided by 2, then multiply by height, so, you did that on one half of the trapezoid, then the result, x2. After that, you multiply the result by 4 since each square foot of the carpet costs $4. Then, the result would be 1840.00.

Hope this helps! :)

Tanya [424]

Answer:

Casey will have 5852.25 in his bank account after 2 years.

Step-by-Step Explaination:

2%=0.02

0.02*5625=112.5

112.5+5625=5737.5

0.02*5737.5=114.75

114.75+5737.5=5852.25

Huck and Jim are waiting for a raft. The number of rafts floating by over intervals of time is a Poisson process with a rate of

Harrizon [31]

Answer: 0.0081

Step-by-step explanation:

Let X be the number of rafts.

Given : The mean number of rafts floating : $\lambda=0.4$ rafts per day .

Then , for 7 days the number of rafts = $\lambda_1=\lambda\times 7=0.4\times7=2.8$ rafts per day .

The formula to calculate the Poisson distribution is given by :_

$P(X=x)=\dfrac{e^{-\lambda_1}\lambda_1^x}{x!}$

Now, the probability that they will have to wait more than a week is given by :-

$P(X>7)=1-P(X\leq7)\\\\=1-(P(0)+P(1)+P(2)+P(3)+P(4)+P(5)+P(5)+P(6)+P(7))\\\\=1-(\dfrac{e^{-2.8}2.8^{0}}{0!}+\dfrac{e^{-2.8}2.8^{1}}{1!}+\dfrac{e^{-2.8}2.8^{2}}{2!}+\dfrac{e^{-2.8}2.8^{3}}{3!}+\dfrac{e^{-2.8}2.8^{4}}{4!}+\dfrac{e^{-2.8}2.8^{5}}{5!}+\dfrac{e^{-2.8}2.8^{6}}{6!}+\dfrac{e^{-2.8}2.8^{7}}{7!})\\\\=1-0.991869258012=0.008130741988\approx0.0081$

Hence, the required probability : 0.0081

Convert 87 degrees to radians in terms of pi

Svetlanka [38]

87 ° to radians in terms of pi =
=> 87 × $\frac{ \pi }{180}$
=> $\frac{29 \pi }{60}$

The principle behind this conversion is that we know that π radians is equal to 180 thus we are simply 'rationalizing' to include π in the answer.
