A standard six-sided die was rolled a number of times, and the results were recorded in the table below. Use this information to

Maru [420]

Answer:

$P(Even) = 0.547$

Step-by-step explanation:

Given

$\begin{array}{ccccccc}{Sides} & {1} & {2} & {3} & {4} & {5} & {6} \ \\ {Freq} & {42} & {51} & {39} & {52} & {44} & {48} \ \end{array}$

Required

P(Even)

The even sides are: 2, 4, 6

So:

$P(Even) = P(2) + P(4) + P(6)$

This is then calculated as:

$P(Even) = \frac{n(2)}{Total} + \frac{n(4)}{Total} + \frac{n(6)}{Total}$

Replace n(2), n(4), n(6) with their frequencies

$P(Even) = \frac{51}{Total} + \frac{52}{Total} + \frac{48}{Total}$

The total frequency is:

$Total =42+51+39+52+44+48$

$Total =276$

So:

$P(Even) = \frac{51}{Total} + \frac{52}{Total} + \frac{48}{Total}$

$P(Even) = \frac{51}{276} + \frac{52}{276} + \frac{48}{276}$

Take LCM

$P(Even) = \frac{51+52+48}{276}$

$P(Even) = \frac{151}{276}$

$P(Even) = 0.547$ --- approximated

Which inequality below will have a dashed boundary line with a shaded area above its graph? A. 7x − y ≤ 3 B. x − y ≤ 4 C. 2x − 9

patriot [66]

Dashed boundary line means there is no equal sign in the problem. That eliminated the first two. Shaded above means it is greater than...

Now turn your inequalities into y = mx + b form
2x - 9y > 2 --- subtract 2x from both sides
-9y > -2x + 2 -- divide by -9...and change inequality sign
y < 2/9x - 2/9 this says y is less then.....we need greater then...this is not it

try the next one...
4x + 7y > 3 --- subtract 4x from both sides
7y > 4x + 3 -- divide by 7
y > 4/7x + 3/7
this says y is greater then...this is the one we want

The answer to your question is D. I hope that this is the answer that you were looking for and it has helped you.
