Rework problem 7 from section 3.4 of your text, involving the selection of a colored ball from one of three bowls. Assume that y
allochka39001 [22]

Answer:

  • Question (1): 1/2 = 0.5

  • Question (2): 1/6 ≈ 0. 17

Explanation:

<u>1. Arrange the information of the balls contained in the bowls in a table:</u>

                       Bowl X      Bowl Y       Bowl Z     Total

Red balls              2               2                1               5

White balls           2                1                3              6

Blue balls             3                1                2              6

                           ==============================

Totals                     7                4              6             17  

<u>2. To answer each question use the basic definition of probabilities</u>

  • Probability = # of favorable events / # of possible events

<u>3. Question (1) If the ball is blue, what is the probability that it was drawn from bowl X? </u>

<u />

  • Number of total blue balls: 6
  • Number of blue balls in the bowl X: 3
  • Probability that a ball that is blue was drawn from the bowl X: P (b/X)

       P (b/X) = number of blue balls in the bowl X / total number of blue balls = 3 / 6 = 1/2 = 0.5

       

<u>4. Question (2) If the ball is either blue or white, what is the probability that it was drawn from bowl Y?</u>

  • Number of total blue and white balls: 6 + 6 = 12
  • Number of blue balls and white balls in the bowl Y: 1 + 1 = 2
  • Probability that a ball that is either blue or white was drawn from the bowl Y: P (b or w / Y)

       P (b or w /Y) = number of blue balls and white balls in the bowl Y / total number of blue balls and white balls = 2 / 12 = 1/6 ≈ 0.17

Alan deposited 300$ into a savings account. At the end of the year, the amount of money in the account had increased to $336. At
motikmotik

Answer:

During the first year he had an annual interest of 12%, and in the second year of 25%

Step-by-step explanation:

To calculate the interest of the first year:

(Initial capital of the first year / final capital of the first year) - 1 = interest of the first year

(300/336) - 1 = 0.12 = 12%

To calculate the interest of the second year:

(Initial capital of the secondyear / final capital of the second year) - 1 = interest of the second year

(336/420) - 1 = 0.25 = 25%

what are the measure measurements of angels a b and c show your work and explain your work and explain your answers
julia-pushkina [17]
A = 40° (Vertically opposite angles) 

b = 180 - 90 - 40 = 50° (Angles in a triangle add up to 180)

c = 180 - 65 = 115° (Adjacent angles on a straight line)
