Answer:

The amount after a time period of 5 years is $287.5.

Step-by-step explanation:

Principal Amount  deposited   =  $250

Time  = 5 Years

Rate of interest = 3%

Now, SIMPLE INTEREST = \frac{P \times R \times T}{100}

⇒SI = \frac{250  \times 3  \times 5}{100}   = 37.5

or, the interest amount after 5 years = $37.5

Now, AMOUNT = PRINCIPAL + INTEREST

                             =  $250  + $37.5  = $287.5

Hence the amount after a time period of 5 years is $287.5.

Suppose that the probabilities are 0.4, 0.3, 0.2, and 0.1, respectively, that 0, 1, 2, or 3 power failures will strike a certain
defon

Answer:

mean = 1 power failure

variance = 1 (power failure)²

Step-by-step explanation:

Since the mean is computed as

mean = E(x) = ∑ x * p(x) for all x

then for the random variable x=power failures , we have

mean = ∑ x * p(x) = 0 * 0.4 + 1* 0.3 + 2*0.2 + 3* 0.1 = 1 power failure

since the variance can be calculated through

variance =  ∑[x-E(x)]² * p(x) for all x

but easily in this way

variance = E(x²) -  [E(x)]² , then

E(x²) = ∑ x² * p(x) = 0² * 0.4 + 1²* 0.3 + 2²*0.2 + 3²* 0.1 = 2 power failure²

then

variance = 2 power failure² - (1 power failure)² = 1 power failure²

therefore

mean = 1 power failure

variance = 1 power failure²

A major convention center, whose floors are covered by a square carpet tiles with side lengths of 9 inches laid out in a 48 by 9
bearhunter [10]

Answer:

option B

$28.80

Step-by-step explanation:

Given the question,

side length of one square tile = 9 inches

area of square tile = l² = 9² = 81 inches²

<h3>Step1</h3>

There are 48(96) = 4608 carpet tiles, so the company was making 4608($.05) = $230.40.

<h3>Step2 </h3>

Now, the company countered with square feet. We have a total of 4608(81) = 373,248 square inches.

1 square foot = 144 square inches.

373,248/144 = 2592 square ft.

2592($.10) = $259.20

$259.20 - $230.40 = $28.80
