To compare two products such as colas, a random sample is selected to taste two types of colas (A and B). Each selected subject

Nadya [2.5K]

Answer: The sample size would be needed = 385

Step-by-step explanation:

Let p be the prior population proportion.

Margin of error = E

When not estimate of p is given , the formula to calculate the minimum sample size <em>n</em> = $0.25(\dfrac{z^*}{E})^2$ , where z* = critical value for given confidence interval.

Here z* for 95% confidence level is 1.96.

E=5%=0.05

Then $n=0.25(\dfrac{1.96}{0.05})^2\approx385$

Hence, the sample size would be needed = 385

Determine whether the given equation has one solution, no solution, or infinitely many solutions.

Katen [24]

Answer:

No Solution.

Step-by-step explanation:

2 - 3(x + 4) = 3(3 - x)

2 - 3x - 12 = 9 - 3x

Move the terms in x to one side and the numbers to the other

-3x + 3x = 9 - 2 + 12

0 = 19.

This is absurd so there is No Solution.

Is (2,11) a solution to the equation y = 3x - 2 ?

AlladinOne [14]

Answer:

No (2, 11) is not a solution.

Step-by-step explanation:

y = 3x - 2

Plug in the points:

11 = 3(2) - 2

Solve:

11 = 6 - 2

11 = 4

11 does not equal 4.

Hope this helps.
