sweet-ann [11.9K]

Answer: C, D

Explanation:

Length: L = x + 3

width: x ≥ y + 2 ⇒ y ≤ x - 2

wheels: y

0.50(L * x) + 4(2.25y) ≤ 50

0.50(x + 3)(x) + 4(2.25y) ≤ 50

0.50(x² + 3x) + 9y ≤ 50

9y ≤ 50 - 0.50(x² + 3x)

9y ≤ 50 - 0.50x² - 1.5x

÷9 ÷9

y ≤ $\frac{50}{9}-\frac{1}{6}x-\frac{1}{18}x^{2}$

*******************************************************************************

15 per person is the rate

22 is the constant

y = 15x + 22

divide that by the number of people (x) to get:

y = $\frac{15x + 22}{x}$

Silk scarves are produced in a factory. Quality control investigations find that 0.5% of the scarves produced have flaws, which

Goshia [24]

The binomial probability is determined by the formula

$\begin{gathered} P_x=\binom{n}{x}p^xq^{n-x} \\ \text{where} \\ P\text{ is the binomial probability} \\ x\text{ is the number of times for a specific outcome within }n\text{ trials} \\ p\text{ is the probability of success on a single trial} \\ q\text{ is the probability of failure on a single trial} \\ n\text{ is the number of trials} \end{gathered}$

Here, we will assume that finding the flaw is the "success" of the trial hence the following given

$\begin{gathered} p=0.05 \\ q=0.95 \\ n=30 \end{gathered}$

Finding the probability of one flawed scarf

$\begin{gathered} P(X=1)=\binom{30}{1}(0.05)^1(0.95)^{30-1} \\ P(X=1)=0.3389 \end{gathered}$

Finding the probability of no flawed scarves

$\begin{gathered} P(X=0)=\binom{30}{0}(0.05)^0(0.95)^{30-0} \\ P(X=0)=0.2146 \end{gathered}$

Finding the probability of more then three flawed scarves

$\begin{gathered} P(X>3)=1-P(X\le3) \\ P(X>3)=1-0.93922843869 \\ P(X>3)=0.0608 \end{gathered}$
