The ages of George and Genemy are in ratio 5:7 . Four years from now the ratio of their ages will be 3:4 .Find their present age

DedPeter [7]

Answer:

Below in bold.

Step-by-step explanation:

Let x be George's age and y be Genemy's age.

x/y = 5/7

(x + 4)/ (y + 4) = 3/4

From equation 1, y = 7x/5 = 1.4x so substituting in equation 2 :

(x + 4)/ (1.4x + 4) = 3/4

3(1.4x + 4) = 4(x + 4)

4.2x + 12 = 4x + 16

0.2x = 16 -12 = 4

x = 4/0.2 = 20 = George's age.

So y = 1.4x = 1.4 * 20 = 28 = Genemy's age.

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
