Answer:
4/15
Step-by-step explanation:
There are red, green and blue marbles in the bag. The total of all the probabilities of selecting red, green and blue marbles is 1.00, or just 1.
So, to find the probability of selecting a blue marble, we add together 1/3 and 2/5 and subtract the total from 1:
1 - (1/3 + 2/5)
or:
1 - (5/15 + 6/15)
or:
1 - 11/15, or 4/15 (answer)
Answer:1/3x is the slope and -4 is the y-intercept
Step-by-step explanation
find -4 on the graph then go up 1 unit then over to the right 3 units
Answer:
What is the probability the mean of his sample will be between $70.00 and $80.00? = 64/64 =1
s1) = 99% =z score = 127/128
s2)64/64 = 1
s3)95% of 64 = 123/128
s4) p) step 3 = 95% of 64 = 60.08 /64 = 60/64 = 93.75%
s5) P)of 2+4 = 283/292 = 96.92%
