Answer:

The smallest sample size to satisfy the conditions is n=500.

Step-by-step explanation:

The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:

$np\geq10\\\\n(1-p)\geq10$

The largest sample size required will be for the minimum p or (1-p).

This happens to be the proportion that can play other instruments: 2%.

Then, we can calculate the minimum sample size as:

$np\geq10\\\\n(0.02)\geq10\\\\n\geq(10/0.02)\\\\n\geq500$

Use the discrimination and select whether the roots of 5x^2-4x+3=0 are real or non-real

Lelu [443]

With a=5, b= -4 and c=3, the discriminant is

16-4(5)(3) = 16-60, a negative number. Thus, the roots are non-real (complex).

Which is the equation of a line parallel to the line with equation y = 3x - 4

mash [69]

Answer:

C. 3x - y = -2

Step-by-step explanation:

We know that lines with the same slope are usually parallel

3x - y = -2

-y = -3x - 2

y = 3x + 2

They have the same slope so we can assume that they're parallel
