This is proportional because in the x axis all the numbers are different.

Find the number, if 3 1/3 of it is 10

Ugo [173]

Answer:

Step-by-step explanation:

You want a number that if it is multiplied by 3 1/3 the result will be 10. Let the number be x

3 1/3 * x = 10 Change to a mixed number

10/3 * x = 10 Multiply by 3/10

(10/3)*x * 3/10 = 10 * 3/10 Combine

x = 10*3 / 10 Simplify

x = 30/10 = 3

A jar of 150 jelly beans contains 22 red jelly beans, 38 yellow, 20 green, 28 purple, 26 blue, and the rest are orange.Let B = t

pentagon [3]

Answer:

$P(R\ and\ B) = 0.0256$

Step-by-step explanation:

Given

$Red = 22$

$Yellow = 38$

$Green = 20$

$Purple = 28$

$Blue = 26$

$Orange = 16$

Required

Determine the probability of red then blue jelly? i.e. P(R and B)

From the question, we understand that the red jelly bean was not replaced. This means that the number of jelly beans reduced by 1 after the picking of the red jelly bean

So, we have:

$P(R\ and\ B) = P(R)\ and\ P(B)$

This is then solved further as:

$P(R\ and\ B) = P(R)\ *\ P(B)$

$P(R\ and\ B) = \frac{n(R)}{Total}\ *\frac{n(B)}{Total - 1}$

The probability has a denominator of Total - 1 because the number of jelly beans reduced by 1 after the picking of the red jelly bean

The equation becomes:

$P(R\ and\ B) = \frac{22}{150}\ *\frac{26}{150- 1}$

$P(R\ and\ B) = \frac{22}{150}\ *\frac{26}{149}$

$P(R\ and\ B) = \frac{22*26}{150*149}$

$P(R\ and\ B) = \frac{572}{22350}$

$P(R\ and\ B) = 0.02559284116$

$P(R\ and\ B) = 0.0256$
