A company rents water tanks shaped like a cylinders. Each tank has a diameter of 12 feet and a height of 3 feet. The cost is $2
12345 [234]

Answer:

\$678.58

Step-by-step explanation:

step 1

<u>Find the volume of the tank</u>

we know that

The volume of a cylinder (water tank) is equal to

V=\pi r^{2}h

in this problem we have

r=12/2=6\ ft -----> the radius is half the diameter

h=3\ ft

substitute

V=\pi (6^{2})(3)=339.29\ ft^{3}

step 2

Find the cost

339.29\ ft^{3}*2\frac{\$}{ft^{3}}=\$678.58

When I visit a local cafe, there's an $80\%$ probability that I'll order a sandwich, and a $70\%$ probability that I'll order a
jeyben [28]

Answer:

There is 55% probability that I order both the sandwich and soup

Step-by-step explanation:

P(sandwich) = 0.8

P(Soup) = 0.7

P(neither sandwich nor soup) = 0.05

P(sandwich or soup) = 1 - P(neither sandwich nor soup)

P(sandwich or soup) = 1 - 0.05 = 0.95

P(Sandwich & Soup) = x

P(Sandwich only) = 0.8 - x

P(Soup only) = 0.7 - x

P(sandwich or soup) = P(Sandwich only) + P(Soup only) + P(Sandwich & Soup)

Note that P(neither sandwich nor soup) has already been used to get the P(sandwich or soup) and should not be included in the above formula. Don't make that mistake!

0.95 = 0.8 - x + 0.7 - x + x

0.95 = 1.50 - x

x = 1.50 - 0.95

x = 0.55

There is 55% probability that I order both the sandwich and soup
