Answer: 3,220

Step-by-step explanation: What you do first is find the volume of the room which is 1,610. So after that you multiply 1,610 by 2 since Maria wants "two" coats of paint on each wall.

Answer:

1.54 gallons of paint.

Step-by-step explanation:

Maria has a rectangular room whose dimensions are 23 feet by 10 feet, with 7 feet ceilings.

Area = 2(length + width) × height

        = 2( 23 + 10)× 7

        = 2 × 33 × 7

       = 462 feet²

Total area of the room that she has to paint is 462 square feet. She wants to paint two coat on each wall.

Now the area would be 462 × 2 = 924 square feet

A gallon of latex paint can cover 600 square feet.

to paint 924 feet² she needs = \frac{924}{600}

                                                = 1.54 gallons of paints.

She needs to buy 1.54 gallons of paint.

A manufactured lot of buggy whips has 20 items, of which 5 are defective. A random sample of 5 items is chosen to be inspected.
dimulka [17.4K]

Answer:

a. 39.55%

b. 44.02%

Step-by-step explanation:

We have the following data:

n = 5

x = 1

p = 5/20 = 0.25

to. If the sampling is done with replacement.

We apply the binomial distribution formula, which is as follows:

P = nCx * (p ^ x) * ((1-p) ^ (n-x))

Where nCx, is a combination, and is equal to:

nCx = n! / x! * (n-x)!

replacing we have:

5C1 = 5! / 1! * 4! = 5

replacing in the main formula:

P = 5 * (0.25 ^ 1) * ((1- 0.25) ^ (5-1))

P = 0.3955

that is, without replacing the probability is 39.55%

b. if the sampling is done without replacement.

Here it is a little different from the previous one, but what you should do is calculate three cases,

the first was the one at point a, when n = 5 and x = 1

5C1 = 5! / 1! * 4! = 5

the second is when n = 20 and x = 5, this is all possible scenarios.

20C5 = 20! / 5! * 15! = 15504

and the third is when n = 15 (20-5) and x = 4 (5-1), which corresponds to the cases when none were damaged

15C4 = 15! / 4! * 11! = 1365

In the end, it would be:

P = (5C1 * 15C4) / 20C5

Replacing:

P = 5 * 1365/15504

P = 0.4402

Which means that without replacing the probability is 44.02%
