Find the area of rectangular ground of length the25√3m and breath 20√6m<br>

Elza [17]

Answer: 500√18

Step-by-step explanation:

Area Of Rectangle = Length × Breadth

Length = 25√3m

Breadth = 20√6m

Area = L×B

= 25√3 × 20√6

= 500√18

Therefore 500√18m is the are of the ground.

Whats 2/5 times 6/7 simplified

hichkok12 [17]

In order to multiply fractions, we multiply the two numerators together, and multiply the two denominators together.

$\frac{2}{5}\times \frac{6}{7} =\frac{2\times6}{5\times7} \\\frac{2\times6}{5\times7} =\frac{12}{35}$

12/35 is the answer

A survey of households in a small town showed that in 850 of 1,200 sampled households, at least one member attended a town meeti

Iteru [2.4K]

Answer:

Hence the confidence interval is ( 0.6745, 0.7422).

Step-by-step explanation:

Now the given are

Sample size = n = 1200

x = 850

Sample proportion is

$\hat{p}=\frac{x}{n}=\frac{850}{1200}=0.7083$

We have to construct 99% confidence interval for the population proportion.

Formula Used:

$(\hat{p}-E , \hat{p}+E)$

Here E is a margin of error.

$E =Zc\times\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}$

Zc = 2.58

$E =2.58\times\sqrt{\frac{0.7083*(1-0.7083)}{1200}}\\\\E=2.58\times\sqrt{0.000172}=0.0339$

So confidence interval is ( 0.7083 - 0.0339 , 0.7083 + 0.0339)

= ( 0.6745 , 0.7422).
