Answer:

The distributive property means that to multiply 3(x-4), you distribute the 3 by multiplying both x and -4 by 3. Therefore, the answer here is (3*x)+(3*-4), which is equal to 3x-12.

Consider the following table with information about a sample of students from GCA and if they had trigonometry before taking AMD

11Alexandr11 [23.1K]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

The conditional probability P(W|X) means "Probability of W happening GIVEN THAT X has happened".

We want to find P(Trig|Male). This would mean, we want people who are male...then we look, how many of them took Trig.

Looking at the table, row and column of Trig & Male is "8".

Hence, Probability would be 8/48 [48 is the total number of people, given in right bottom most part of the table]

8/48 = 1/6

Correct answer is 2nd option, 1/6

An opinion poll reported that 36% believe a certain governor broke campaign financing laws in his election campaign. How many pe

77julia77 [94]

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
