Answer:I would need more information to help you
Step-by-step explanation:
Answer:
- 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
A=60 B=60 c=60 d=90 e=90 f=60 h=60
i=90 j=90 k=120 m=60 n=120 o=90
p=90 q=60 r=120 s=120 t=60 u=90 v=90 w=150 x=40 y=150 z=30
First, find the relationship between the number of minutes, x, she works and the number of sundaes,s, she makes
She makes s = [1sundae / 2 minutes]* x = x/2
Now find the relation of the earnings, E, with the number of sundaes she works
E = $1.20* s = 1.2s.
And finally, relate E with the number of minutes she works, x: E = 1.2 [ x/2]
E = 0.6x
The correct answer is C (-20) let me know if you want to know how I got that answer
