What (3×5^2)/(5)^2 equal? Plz answer fast and with work and I will give brainliest
balu736 [363]

Answer:

The answer is 3.

Step-by-step explanation:

Given that the Indices Law is,

{a}^{m}  \div  {a}^{n}  =  {a}^{m - n}

{a}^{0}  = 1

So the expression is :

3 \times  {5}^{2}  \div  {5}^{2}

= 3 \times  {5}^{2 - 2}

= 3 \times  {5}^{0}

= 3 \times 1

= 3

In a sample of 388 people in a certain, 22% had red hair. Find a 99% confidence interval for the proportion of people in the cou
Anit [1.1K]

Answer: (0.1658, 0.2742)

Step-by-step explanation:

Formula to find the confidence interval for population proportion is given by :-

\hat{p}\pm z^*\sqrrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

, where  n= sample size

z*= Critical value

\hat{p} = sample proportion.

As per given , we have

Significance level : \alpha=1-0.99=0.01

According to z-table, Critical value for 99% confidence interval : z*=2.576

Let p be the proportion of people in the country that have red hair.

n= 388

\hat{p}=0.22

Now, required confidence interval for proportion of people in the country that have red hair will be :-

0.22\pm (2.576)\sqrt{\dfrac{0.22(1-0.22)}{388}}

0.22\pm (2.576)\sqrt{0.000442268}

0.22\pm (2.576)(0.02103)

(0.22-0.05417328,\ 0.22+0.05417328 )=(0.16582672,\ 0.27417328)\\\\\approx(0.1658,\ 0.2742)

The 99% confidence interval for the proportion of people in the country that have red hair= (0.1658, 0.2742)
