What value of c makes the polynomial below a perfect square?

1 answer:

6 0

The value for c is A. 49. That comes from the process of completing the square where you take half the linear term, square it, and add it in. Our linear term is 14. Half of 14 is 7, and 7 squared is 49. So A

Given that z is a standard normal random variable, find z for each situation. The area to the right of z is .1314. (Round to two

Mumz [18]

Answer:

$P(Z>0.1314) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.1314,0,1,TRUE)" or the standard normal table

$P(Z$

We can use the following excel code: "=NORM.DIST(0.75,0,1,TRUE)" or the standard normal table.

$P(Z>0.01) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.01,0,1,TRUE)" or the standard normal table

Step-by-step explanation:

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

$P(Z>0.1314) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.1314,0,1,TRUE)" or the standard normal table

$P(Z$

We can use the following excel code: "=NORM.DIST(0.75,0,1,TRUE)" or the standard normal table.

$P(Z>0.01) = 1-P(Z$

We can use the following excel code: "=1-NORM.DIST(0.01,0,1,TRUE)" or the standard normal table

Find a polynomial function that has the given zeros. (there are many correct answers.) 0, 1, 6

aev [14]

Since those are the zeros, we can say that the equation would have to be
x(x-1)(x-6), then we just expand to get x^3 - 7x^2 + 6x

Can someone explain how I'm supposed to determine whether each pair of ratios form a proportion? I so stuck on it sorry can i ge

Natalka [10]

Step-by-step explanation:

We will learn how to solve proportion problems. We know, the first term (1st) and the fourth term (4th) of a proportion are called extreme terms or extremes, and the second term (2nd) and the third term (3rd) are called middle terms or means.

Therefore, in a proportion, product of extremes = product of middle terms

example

1. Check whether the two ratios form a proportion or not:

(i) 6 : 8 and 12 : 16; (ii) 24 : 28 and 36 : 48

Solution:

(i) 6 : 8 and 12 : 16

6 : 8 = 6/8 = 3/4

12 : 16 = 12/16 = 3/4

Thus, the ratios 6 : 8 and 12 : 16 are equal.

Therefore, they form a proportion.

What are the common factors of 18 and 30? What do they represent?

Zolol [24]

Factor out 18.

The factors for 18 are as listed:

1, 2, 3, 6, 9, 18

Now factor out 30.

The factors for 30 are as listed:

1, 2, 3, 5, 6, 10, 15, 30

Now look at the factors that are both factors for 18 and 30.

So, the common factors are 2, 3, and 6.
