Three urns of the same appearance are given as follows: Urn A contains 5 red and 7 white balls. Urn B contains 4 red and 3 white balls. Urn C contains 3 red and 4 white balls. An urn is selected at random and ball is drawn from the urn. (1) What is the probability that the ball drawn is red. (2) If the ball drawn is red, what is the probability that it came from urn A.​

Answers

a) The probability that the ball drawn is red is approximately 0.4615

b) If the ball drawn is red, the probability that it came from urn A is approximately 0.7222.

To calculate the probabilities, we can use the following formulas:

a) Probability of drawing a red ball (R):

P(R) = (Number of red balls) / (Total number of balls)

b) Probability that the ball came from urn A given that it is red (R|A):

P(R|A) = (Probability of drawing a red ball from urn A) / (Probability of drawing a red ball)

Let's calculate both probabilities:

a) Probability of drawing a red ball:

Total number of red balls = 5 (Urn A) + 4 (Urn B) + 3 (Urn C) = 12

Total number of balls = 5 (Urn A) + 7 (Urn A) + 4 (Urn B) + 3 (Urn B) + 3 (Urn C) + 4 (Urn C) = 26

P(R) = 12 / 26 ≈ 0.4615

b) Probability that the ball came from urn A given that it is red:

P(R|A) = (Probability of drawing a red ball from urn A) / (Probability of drawing a red ball)

P(R|A) = (5 / 12) / (12 / 26) = (5 / 12) * (26 / 12) ≈ 0.7222

Jarrett splits his bag of j jelly beans into two equal piles and gives one pile to his brother. He then gives his brother seven more beans. Write an algebraic expression to represent the number of beans his brother has?

Answers

Answer: j/2+7= the amount his brother has

Step-by-step explanation:

I'm going to do an example equation, so let's pretend j=30

Step 1: Divide the jelly beans in half (by 2)

30/2=15  

Step 2: So now they each have 15 jellybeans, but if Jarrett gives his brother 7 jellybeans...

15+7= 22

Answer:

½j + 7

Step-by-step explanation:

j = jelly beans

Jarrett splits his bag of j jelly beans into two equal piles

so now we have two equal piles of the jelly beans

½j  and  ½j

and gives one pile to his brother

so right now the brother has
½j

He then gives his brother seven more beans

we add 7 to our equation and now

this is the algebraic expression that represents the number of beans the brother has:

½j + 7

If two hamburger and one soda cost $6 and one hamburger and two sodas cost $4.50, find the cost of one hamburger and one soda.

Answers

One hamburger and one soda would cost $3.50.
Because one hamburger costs $2.50, and one soda costs $1.00.
And if two hamburgers and one soda costs $6.00, 2x$2.50(Hamburgers)=$5+$1(Soda)=$6. One hamburger and two sodas costs $4.50. 2x$1.00(Soda)=$2.00+$2.50=$4.50.

Joseph wants to estimate 1 3/7 * 5 4/3 To estimate, he simplifies the expression 1 1/2 * 6

Is Joseph’s estimate a close estimate, an underestimate, or an overestimate?

Answers

1 (3)/(7) * 5 (4)/(3) =  (10)/(7) * (19)/(3) =  (190)/(21) \approx 9,0476..
When he simplified the expression:
1 (1)/(2) *6= (3)/(2) * (6)/(1) =  (18)/(2) = 9
9,047 \approx 9,05 \approx 9
I think  Joseph's estimate a close estimate.

Madelyn jokes 190.5 meters up a mountain . I’d she is 62 percent of the way up how tall is the mountain?

Answers

The mountain is 307.26 meters tall.

Step-by-step explanation:

Given,

Distance jogged by Madelyn = 190.5 meters

This represents 62 percent of total height of mountain.

Let,

x be the height of mountain.

62% of x = 190.5

(62)/(100)*x=190.5\n0.62x=190.5

Dividing both sides by 0.62

(0.62x)/(0.62)=(190.5)/(0.62)\nx=307.258

Rounding off to 2 decimal places

x = 307.26 meters

The mountain is 307.26 meters tall.
