Answer:

704 square yards

Step-by-step explanation:

10 * 19 = 190

190 * 2 = 380

12 * 19 = 228

12 / 2 = 6

6 * 8 = 48

48 * 2 = 96

96 + 228 + 380 = <em><u>704</u></em>

Solve the equation x = 5/3 (pie) (r^3) for r.

DENIUS [597]

Answer and Step-by-step explanation:

To solve for r, we need to get everything away from r. We can start off by moving five thirds, and pi.

$x = \frac{5}{3} \pi r^{3}$

Multiply each side by $\frac{3}{5}$ , then divide by $\pi$ (pi)

$\frac{3x}{5\pi } = r^{3}$

Now, take the cubed root of both sides.

$\sqrt[3]{\frac{3x}{5\pi } } = r$

^^ That is the answer.

Answer:

x^2 -9

Step-by-step explanation:

(x + 3)(x − 3)

FOIL

first x*x =x^2

outer -3x

inner 3x

last -3*-3 =-9

Add together

x^2 -3x+3x -9

Combine like terms

A binomial event has n = 60 trials. The probability of success for each trial is 0.20. Let x be the number of successes of the e

OLga [1]

Answer:

12 and 3.0984

Step-by-step explanation:

Binomial probability distribution

Probability of exactly x sucesses on n repeated trials, with p probability.

The expected value of the binomial distribution is:

$\mu_{x} = np$

The standard deviation of the binomial distribution is:

$\sigma_{x} = \sqrt{np(1-p)}$

In this problem, we have that:

$n = 60, p = 0.2$

So

$\mu_{x} = np = 60*0.2 = 12$

$\sigma_{x} = \sqrt{np(1-p)} = \sqrt{60*0.8*0.2} = 3.0984$

So the correct answer is:

12 and 3.0984

A box contains 23 transistors,6 of which are defective. If 6 are selected at random, find the probility that none are defective

ipn [44]

$|\Omega|=C(23,6)=\dfrac{23!}{6!17!}=100947\\
|A|=C(17,6)=\dfrac{17!}{6!11!}=12376\\\\
P(A)=\dfrac{12376}{100947}=\dfrac{1768}{14421}$
