Two friends are opening a coffee shop. As they write their business plan, they research the amount of debt similar businesses ca

n have in the first two years of opening. It is known that
72% of coffee shops have a debt of over $50,000 within the first two years of opening. If a random sample of 36 coffee shops is obtained, what is the probability that more than half of them had a debt of over $50,000 within the first two years of opening?

Answer:   0.9984

Step-by-step explanation:

Let p be the proportion of coffee shops have a debt of over $50,000 within the first two years of opening.

As per given , p= 72%=0.72

Sample size : n= 36

Required probability :-

P(\hat{p}>0.50)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.50-0.72}{\sqrt{\dfrac{0.72(1-0.72)}{36}}})\\\\=P(z>-2.94)\ \ \ [\because z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\=P(z

Hence, the probability that more than half of them had a debt of over $50,000 within the first two years of opening = 0.9984

One of the sides of an equilateral triangle is 32. What is the height of the triangle? Round to 2 decimal places.
Ilya [14]
So because it's an equilateral triangle, you can cut the triangle in half and make a right triangle with a hypotenuse of 32. The bottom of the triangle would be half of 32, which is 16, because you cut the triangle in half. Now you can use the pythagorean theorem to solve for the height.

16^{2} +b^{2} =32^{2}

The answer is whatever b is:

b = \sqrt{ 32^{2} - 16^{2}

So your answer is 27.713.
