Paul [167]

Given:

Jerome ate 1/2 of the sandwich , Kevin ate 1/3 of the sandwich, and Seth ate the rest.

To find:

The ratio of jerome's share to kevin's share to seth's share.

Solution:

Jerome ate 1/2 of the sandwich. So,

Jerome's share = $\dfrac{1}{2}$

Kevin ate 1/3 of the sandwich. So,

Kevin's share = $\dfrac{1}{3}$

Seth ate the rest. So,

Seth's share = $1-\dfrac{1}{2}-\dfrac{1}{3}$

= $\dfrac{6-3-2}{6}$

= $\dfrac{1}{6}$

The ratio of jerome's share to kevin's share to seth's share is:

$\dfrac{1}{2}:\dfrac{1}{3}:\dfrac{1}{6}$

To simplify the ratio multiply the ratio by 6.

$\dfrac{1}{2}\times 6:\dfrac{1}{3}\times 6:\dfrac{1}{6}\times 6$

$3:2:1$

Therefore, the ratio of jerome's share to kevin's share to seth's share is 3:2:1.

That equation has no graph. If it had a solution, the solution would be a single number. But that particular equation has no solution either ... there is no number that 'x' could be that would make the equation true.

You have a jar of marbles with 7 red, 12 blue, 6 yellow, and 9 white. What is the probability of selecting a marble that is not

Schach [20]

Answer:

The probability of selecting a marble that is not red, replacing it and then one that is white is 0.2102

Step-by-step explanation:

Number of red marbles = 7

Number of blue marbles = 12

Number of yellow marbles = 6

Number of white marbles = 9

Total marbles = 7+12+6+9=34

Probability of selecting red marble = $\frac{7}{34}$

Probability of selecting no red marble = $1-\frac{7}{34}=\frac{27}{34}$

Now replacing it one marble is drawn again

So, Probability of getting white marble $=\frac{9}{34}$

So,the probability of selecting a marble that is not red, replacing it and then one that is white = $\frac{27}{34} \times \frac{9}{34}=0.2102$

Hence the probability of selecting a marble that is not red, replacing it and then one that is white is 0.2102
