Answer:

51/28 or 1 23/28

Step-by-step explanation:

The LCD here is 9. Rewrite 5 2/3 first as 17/3, and then multiply numerator and denominator both by 3, obtaining the equivalent 51/9.

Then divide 51/9 by 28/9: Equivalently, invert the divisor (28/9) and multiply:

(51/9)(9/28) = 51/28 or 1 23/28

5 2/3 divided by 3 1/9 is 1 23/28.

Answer:

The number of people would have participate in opinion poll

n = 15,267

Step-by-step explanation:

Step(i):-

Given data an opinion poll reported that 36% believe a certain governor broke campaign financing laws in his election campaign.

Given proportion = 36% =0.36

Given the margin of error = 1% =0.01

Level of significance = 99% 0 r 0.01

Z₀.₀₁ = 2.576

step(ii):-

The margin of error of Population proportion is determined by

$M.E = \frac{Z_{0.01} \sqrt{p(1-p)} }{\sqrt{n} }$

$0.01 = \frac{2.576 \sqrt{0.36(1-0.36)} }{\sqrt{n} }$

$\sqrt{n} = \frac{2.576 \sqrt{0.36(1-0.36)} }{0.01 }$

√n = 123.648

Squaring on both sides , we get

n = 15,267

final answer:-

The number of people would have participate in opinion poll

n = 15,267

Can someone please help me?

Answer:

Step-by-step explanation:

That composite figure is made up of a square and a quarter of a circle. We will first find the area of the square. Then we will find the area of the circle and divide it by 4.

Area of square = 1.6 × 1.6

Area of square = 2.56 m squared

Area of circle = (3.14)(1.6²) In case you forgot, the area of a circle is A = πr².

Area of circle = 8.0384

Divide that by 4 to get 2.0096.

Add 2.0096 to 2.56 to get the total area, which is

4.5696 or 4.6 rounded (choice D)

What is the height of the building? need help ASAP!

stiv31 [10]

Answer:

178.2 ft

Step-by-step explanation:

$\sin(60) = \frac{x}{200} \\ \frac{ \sqrt{3} }{2} = \frac{x}{200} \\ x = 100 \times \sqrt{3}$

So,

$h = 5 + x = 5 + 100 \times \sqrt{3} = 178.2$

masha68 [24]

So BC is 2x+1 and they are telling you that if your x is 5 then what is BC
So you have to plug in the 5 into your equation
2(5)+1
10+1
11
So BC is 11
