A ball is drawn randomly from a jar that contains 7 red balls, 5 white balls, and 4 yellow ball. Find the probability of the giv

Furkat [3]

Missing Part:

a. A red ball is drawn

b. A white ball is drawn

Answer:

a. $P(Red) = 0.4375$

b. $P(White) = 0.3125$

Step-by-step explanation:

Given

$Red = 7$

$White = 5$

$Yellow = 4$

First, we need to calculate the total

$Total = Red + White + Yellow$

$Total = 7+5+4$

$Total = 16$

Solving (a): Probability of Red.

This is calculated by dividing number of red balls by the total

So:

$P(Red) = \frac{Red}{Total}$

$P(Red) = \frac{7}{16}$

$P(Red) = 0.4375$

Solving (a): Probability of White.

This is calculated by dividing number of white balls by the total

So:

$P(White) = \frac{White}{Total}$

$P(White) = \frac{5}{16}$

$P(White) = 0.3125$

Mikel asked her father how old he is gues the father said I you add the digits that make my age this year you'll get a number th

Alexxx [7]

Answer:

For the sum of the digits of Michelle’s father to drop to 1/3 of its’ former value, the second digit must go from 9 to 0, in one year.

Thus, if he is 39 this year, the sum of the digits of his age will be 12. Next year, when the sum of the digits would be 4+0, or 4, then the digits of his age would be 1/3rd of their former value.

Therefore, he is 39, and will be 40 next year

A school is selling tickets to their Spring theater production. Student tickets cost $6 each and non-student tickets cost $9 eac

I am Lyosha [343]

Answer:

x=137

y=525-137

y=388

Step-by-step explanation:

Let the student tickets be x

Let the geral Admission tickets be y

x+y=525

y=525-x

4x+6y=2876 (subsitute for y)

4x+6(525-x)=2876

4x+3150-6x=2876

-2x=-274

x=137

y=525-137

y=388

Hence, about 137 childern tickets were sold and 388 gernal admission tickets were sold.
