Answer:

In this case, they are using a simple random sampling method, because in each store they choose 100 random people without stratifying them or put any condition. In the simple random sampling method, the samples have the same probability to be chosen, but it isn't reliable in big populations. The population is all the costumers that visit all the stores, while the sample is just the costumers that were surveyed in all the stores. So, it's a simple random sampling method, and the population is all the people that visit all the stores.

Which of the following graphs represents the equation y -4 =3 (x-1)
kondaur [170]
To start, we can factor the "3" in the parentheses - then move the -4 over. So,

y - 4 = 3x - 3
y = 3x + 1

So the y-intercept of the equation is "1", and the slope is 3.

I need help answering this question
Advocard [28]

Answer:

x = 17

Step-by-step explanation:

Since line m is parallel to line n, therefore:

(6x + 5) + (5x - 12) = 180 (consecutive interior angles are supplementary)

Solve for x

6x + 5 + 5x - 12 = 180

Add like terms

11x - 7 = 180

Add 7 to both sides

11x - 7 + 7 = 180 + 7

11x = 187

Divide both sides by 11

\frac{11x}{11} = \frac{187}{11}

x = 17

PLSSS HELPPPP I WILLL GIVE YOU BRAINLIEST!!!!!! PLSSS HELPPPP I WILLL GIVE YOU BRAINLIEST!!!!!! PLSSS HELPPPP I WILLL GIVE YOU B
Naddika [18.5K]
The formula is:

V=Bh or V= l x w x h

I will use the l x w x h

So we know what the values are for each unit, so we would plug them in:

L x W x H = 10 x 2.3 x 4.5

Multiply the values which gets you 103.5


So the answer is 103.5 units cubed.

Why can you NOT combine 3x and 5x^2 ?
diamong [38]
Although they are the same variable, you cannot add two variables raised to different powers. 3x^1 + 5x^2 cannot work, but 3x^2 + 5x^2 can. Also, if you are multiplying them, they would combine to be 15x^3, as 3 and 5 (The coefficients) multiply together and x^2 times x^1 = x^3.

I hope that helps.
