Answer:
18
Step-by-step explanation:
I did my method that I was taught but if you do (-5) - (-2), you get 3. So you subtract 39 by the -21 to get 18.

Answer:
P(Y=r) = 
Step-by-step explanation:
Given that a bag contains 1 red, 3 green, and 5 yellow balls. A sample of four balls is picked, with replacement
When balls are picked with replacement, each time the ball picked up does not depend on the previous outcomes.
Thus given y=2 will not affect the pdf of G
In G, Y no of yellow balls can take values as 0,1,2,3,4
Prob of drawing a yellow ball each time = 5/9
Y = no of yellow balls is binomial with n =4 and p = 5/9
P(Y=0) = 
In general,
P(Y=r) =
Answer:
What two consecutive odd integers have a sum of 88? x + x + 2 = 88 • 2x + 2 = 88 • 2x = 86 • x = 43, x + 2 = 45 • 43 + 45 = 88 • Ans: 43, 45 • They equal 88 and are both odd.
I'm confused too and I'm supposed to be an expert. I'm not entirely sure what frequency density is. We'll just treat this as a histogram.
Let's assume each five minute interval gives a value equal to or proportional to the number of people that finished in that interval.
From 0 to 50 we have 10 intervals; let's just make this into a table
0-5 0
5-10 40
10-15 40
15-20 30
20-25 30
25-30 25
30-35 25
35-40 25
40-45 25
45-50 15
From 0 to 40 that adds up to
0+40+40+30+30+25+25+25 = 215
From 0 to 50 that's
215+25+15 = 255
The fraction less than 40 is 215/255 = 43/51 ≈ .843
Answer: 84.3%
