$3(5+2n) \ \textgreater \ 7 +10n \\ \\ 15 + 6n \ \textgreater \ 7 + 10n \\ \\ 15 \ \textgreater \ 7 + 10n - 6n \\ \\ 15 \ \textgreater \ 7 + 4n \\ \\ 15 - 7 \ \textgreater \ 4n \\ \\ 8 \ \textgreater \ 4n \\ \\ \frac{8}{4} \ \textgreater \ n \\ \\ 2 \ \textgreater \ n \\ \\ n \ \textless \ 2 \\ \\$

The final result is: n < 2.

The proportion of left handed people in the population is about 0.10. Suppose a random sample of 300 people is observed. (a) Wha

pantera1 [17]

Answer: $(\hat{p})\sim N(0.10,\ 0.017)$

Step-by-step explanation:

Sampling distribution of the sample proportion $(\hat{p})$ :

$(\hat{p})\sim N(p,\ \sqrt{\dfrac{p(1-p)}{n}})$

The sampling distribution of the sample proportion $(\hat{p})$ has mean = $\mu_{\hat{p}}=p$ and standard deviation = $\sigma_{\hat{p}}=\sqrt{\dfrac{p(1-p)}{n}}$ .

Given : The proportion of left handed people in the population is about 0.10.

i.e. p=0.10

sample size : n= 300

Then , the sampling distribution of the sample proportion $(\hat{p})$ will be :-

$(\hat{p})\sim N(0.10,\ \sqrt{\dfrac{0.10(1-0.10)}{300}})$

$(\hat{p})\sim N(0.10,\ \sqrt{0.0003})$

$(\hat{p})\sim N(0.10,\ 0.017)$ (approx)

Hence, the sampling distribution of the sample proportion $(\hat{p})$ is $(\hat{p})\sim N(0.10,\ 0.017)$

168 adult tickets

Step-by-step explanation:

3.75(82) (82 students)

307.5

2071.5 - 307.5 ( you subtract since you only need to know the number of adults)

1764

1764/10.5 (you divide since each adult is 10.5$)

Help!!!!!!!!!!!!!!! A square tabletop has side lengths of (4x − 8) units. Enter a polynomial that represents the area of the tab

kherson [118]

Answer: $16x^{2}-64x+64$

Step-by-step explanation:

1. The formula for calculate th area of a square is shown below:

$A=s^{2}$

Where s is the side of the square.

2. Therefore, if the square tabletop has side lengths of (4x-8) units you have:

$(4x-8)^{2}$

3. By definition, the square of a binomial is always a trinomial:

$(a-b)^{2}=a^{2}-2ab+b^{2}$

4. Then, you obtain:

$(4x-8)^{2}=(4x)^{2}-2(4x)(-8)+8^{2}=16x^{2}-64x+64$
