G(n) = 2n^2 - 4n; Find g(-9)

Mathematics
1 answer:
rusak2 [61]2 years ago
6 0

Answer:

g(n) = 2n^2 - 4n; Find g(-9)

The answer is 170, because you have to plug in -9 for all the N values. When you do that, just follow PEMDAS.

P-Parentheses

E-Exponents

M-Multiplication

D-Division

A-Addition

S-Subtraction

Step-by-step explanation:

g(-9) = 2(-9)^2 - 4(-9)

g(-9) = 18^2 -4(-9)

g(-9) = 134+36

g(-9) = 170

I really hope this helps!

Sincerely,

Simplify -4+5x-17-22x
Elina [12.6K]
<h3>Answer:</h3>

\large\boxed{-17x-21}

<h3>Step-by-step explanation:</h3>

In this question, we're simply combining "like-terms" in order to simplify the expression.

Lets solve:

-4+5x-17-22x\\\\\text{First, lets add 5x and -22x}\\\\-17x-4-17\\\\\text{Now we would add the -4 and -17. Adding 2 negatives still keeps it a negative}\\\\-17x-21

When you're done solving, you should get -17x-21

This means that -17x-21 would be the simplified version.

<h3>I hope this helped you out.</h3><h3>Good luck on your academics.</h3><h3>Have a fantastic day!</h3>

Suppose a large shipment of laser printers contained 18% defectives. If a sample of size 340 is selected, what is the probabilit
lukranit [14]

Answer:

The probability that the sample proportion will be greater than 13% is 0.99693.

Step-by-step explanation:

We are given that a large shipment of laser printers contained 18% defectives. A sample of size 340 is selected.

Let \hat p = <u><em>the sample proportion of defectives</em></u>.

The z-score probability distribution for the sample proportion is given by;

                         Z  =  \frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n}}  }  ~ N(0,1)

where, p = population proportion of defective laser printers = 18%

            n = sample size = 340

Now, the probability that the sample proportion will be greater than 13% is given by = P(\hat p > 0.13)

         P(\hat p > 0.13) = P( \frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n}}  } > \frac{0.13-0.18}{\sqrt{\frac{0.13(1-0.13)}{340}}  } ) = P(Z > -2.74) = P(Z < 2.74)

                                                                      = <u>0.99693</u>

The above probability is calculated by looking at the value of x = 2.74 in the  table which has an area of 0.99693.
