Harman [31]
The product of 5 and n is 5n. Since the expression is 6.7 more than this product, we add 6.7 to 5n. the expression becomes:

5n+6.7

1. The mean number of siblings for respondents in a survey is 3.76 with a standard deviation of 3.18. Calculate the Z score asso
allsm [11]

Answer:

-0.24 ; 0.71

Step-by-step explanation:

Given that :

Mean number of siblings (m) = 3.76

Standard deviation (s) = 3.18

Z score associated with 3 siblings

x = 3

Using the relation :

Zscore = (x - m) / s

Zscore = (3 - 3.76) / 3.18

Zscore = - 0.76 / 3.18

Zscore = −0.238993

Zscore = - 0.24

2.) proportion of respondents with more than 2 siblings

Using the z probability calculator :

X > 2

Obtain the standardized score :

Zscore = (x - m) / s

Zscore = (2 - 3.76) / 3.18

Zscore = - 1.76 / 3.18

Zscore = −0.5534591

Zscore = - 0.55

Using the z table :

P(Z ≥ - 0.55) = 1 - p(Z ≤ - 0.55) ; p(Z ≤ - 0.55) = 0.2912

1 - p(Z ≤ - 0.55) = 1 - 0.2912 = 0.7088 = 0.71

Pls help I dont get and pls dont troll I need help thank youuuu
miss Akunina [59]

Answer:

(I am assuming that you don't need the answer, but just an explanation of what to do.) Let's take the first problem for an example the first thing you are going to do is subtract 12 on both sides and you will get n> -1 so then you will put a open circle on -1 going to the right.

Hope this helps :)

What is the complete factorization of the polynomial below?
aksik [14]

Option A: (x+1)(x+3 i)(x-3 i) is the complete factorization of the polynomial x^{3} +x^{2} +9x+9

Explanation:

The polynomial is x^{3} +x^{2} +9x+9

Now, we shall find the complete factorization of the polynomial.

Let us group the common terms, we have,

\left(x^{3}+x^{2}\right)+(9 x+9)

Taking out the common terms,

x^{2} (x+1)+9(x+1)

Factor out x+1 from both the terms, we have,

\left(x^{2}+9\right)(x+1)=0

The term \left(x^{2}+9)\right. can be factored as

\begin{aligned}x^{2}+9 &=0 \\x^{2} &=-9 \\x &=\pm 3 i\end{aligned}  and \begin{aligned}x+1 &=0 \\x &=-1\end{aligned}

Thus, the roots are x=\pm 3 i and x=-1

These roots can be written as (x+1)(x+3 i)(x-3 i)

Thus, the complete factorization of the polynomial is (x+1)(x+3 i)(x-3 i)
