first off, let's convert the mixed fraction to improper fraction and then proceed, let's notice that by PEMDAS or order of operations, the multiplication is done first, and then any sums.

\stackrel{mixed}{1\frac{7}{8}}\implies \cfrac{1\cdot 8+7}{8}\implies \stackrel{improper}{\cfrac{15}{8}} \\\\[-0.35em] ~\dotfill\\\\ -\cfrac{3}{4}~~ + ~~\cfrac{15}{8} \div \cfrac{1}{2}\implies -\cfrac{3}{4}~~ + ~~\cfrac{15}{8} \cdot \cfrac{2}{1}\implies -\cfrac{3}{4}~~ + ~~\cfrac{15}{4} \\\\\\ \cfrac{-3+15}{4}\implies \cfrac{12}{4}\implies 3

A rectangular field has a length that is 90 feet more than twice the width of the field. If the area of the field is 58,500 squa
iragen [17]

Answer:

D. 150 feet

Step-by-step explanation:

The formula for the area of a rectangle is:  area = lw, where l = length and w = width.  In this case, the length is defined as '90 feet more than twice the width' or l = 2w + 90.  If we put this expression in for the value of 'l' in our formula for area we get:

area = w(2w +90), distribute: area = 2w² + 90w = 58500

Subtracting 58500 from both sides, we get the following polynomial:

2w² + 90w - 58500

We can divide all the terms by '2' to simplify:

w² + 45w - 29250

Next, we look for the two factors of 29,250 that will add up to 45, which is -150 and +190 to factor our polynomial:

(w - 150)(w + 190) = 0

Setting both equations equal to 0 and solving for w:

w - 150 = 0 or w = 150

w + 190 = 0 or w = -190

Since our with can not be negative, then the correct width of the field is 150 ft.

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. The probability that none of the LED light bulbs are defective is 0.2213.

<h3>What is Binomial distribution?</h3>

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,

P(x) = ⁿCₓ (pˣ) (q⁽ⁿ⁻ˣ⁾)

Where,

x is the number of successes needed,

n is the number of trials or sample size,

p is the probability of a single success, and

q is the probability of a single failure.

Given the probability of a bulb being a failure is 14%, therefore, the probability of bulb passing the quality check is 86%.

Let the probability of success be defined as 0.14 for binomial distribution, and the probability for failure be 0.86. Therefore, The probability that none of the LED light bulbs are defective is

P(x=0) = ¹⁰C₀ (0.14)⁰ (0.86)¹⁰ = 0.2213

Hence, The probability that none of the LED light bulbs are defective is 0.2213.
