You don't have to answer them all but help me out !!

Mandarinka [93]

Answer:

1. 10n

2. 3x^2z^2

3. 2(9n^3 - 3n^2 + 3n - 1)

4. (Put the same thing)

5. There are no common factors so it is completely factored out.

Step-by-step explanation:

For 1, you gotta find the gcf of the numbers and the variables. So, the common factor of 90, 70, 70, and -80 is 10. Nothing else greater than 10 divides these numbers. For the variables, only "n" is the GCF, as there is one "n" and all the other numbers have n^2 and etc.

For 2, same thing, you have to find the gcf for the numbers and the variables.

3. same thing ;-; (gcf is 2 btw, nothing divides the variables because 2 has no "n".

4. theres nothing that divides the numbers or the variables. So, the gcf is just 1.

Assume the number of typo errors on a single page of a book follows Poisson distribution with parameter 1=3. Calculate the proba

asambeis [7]

Answer:

(i). 0.03981

(ii).0.0048

Step-by-step explanation:

The probability density function of Poisson distribution is:

$P(X=x,\lambda)=\frac{e^{-\lambda}\lambda^x}{x!} \; \;\;\,\; x=0,1,2,...$

Consider <em>X</em> is a number of typos error on a single page of a book and <em>X</em> follows the Poisson distribution with $\lambda = \dfrac{1}{3}$

(i) Exactly two typos:

$\begin{aligned}P(X = 2,\frac{1}{3})&=\frac{e^{-\frac{1}{3}}\frac{1}{3}^{2}}{2!}\\&=\frac{e^{-\frac{1}{3}}}{18}\\&=0.03981\end{aligned}$

(ii) Two or more typos:

$\begin{aligned}P(X\geq2,\frac{1}{3})&=1-[P(X=0)+P(X=1)+P(X+2)]\\&=1-[0.7165+0.2388+0.03981]\\&=1-0.9952\\&=0.0048\end{aligned}$

Jim is a radio ad salesperson. He is paid 17 percent for every ad he sells. He sold an ad today for $2,000.00. What is his commi

stiks02 [169]

Answer:

$340

Step-by-step explanation:

Given:

Jim is paid 17% for every ad he sells.

He sold an ad today for $2000

Now we have to find the commission.

The commission rate is 17%

If he sells $100, then he gets $17 as commission.

To find the commission on sale ad of $2000, we have to multiply 2000 by 17%

17% of 2000

= $\frac{17}{100} *2000$

We can simplify 2000 by 100, we get

= 17*20

Commission = $340

He gets $340 as commission for the ad sale of $2000.
