Answer:
40%
Step-by-step explanation:
From the given statements:
The probability that it rains on Saturday is 25%.
P(Sunday)=25%=0.25
Given that it rains on Saturday, the probability that it rains on Sunday is 50%.
P(Sunday|Saturday)=50%=0.5
Given that it does not rain on Saturday, the probability that it rains on Sunday is 25%.
P(Sunday|No Rain on Saturday)=25%=0.25
We are to determine the probability that it rained on Saturday given that it rained on Sunday, P(Saturday|Sunday).
P(No rain on Saturday)=1-P(Saturday)=1-0.25=0.75
Using Bayes Theorem for conditional probability:
P(Saturday|Sunday)=
=
=0.4
There is a 40% probability that it rained on Saturday given that it rains on Sunday.
Answer: c
I answered c and got a 100 so it has to be it
Answer:
2.5
Step-by-step explanation: i just solved it and it was correct. 300-250=50 50 divided by 20 is 2.5. you divide it by 20 because you have to isolate h in 20h by itself. and to do that you divide 20h by 20
Answer:
1 mile = 15 seconds
Step-by-step explanation:
3 minutes and 15 seconds = 3 min + 15 sec
1 minute = 60 seconds
15 seconds =15/60 = 0,25 min
then
3minutes and 15 seconds = 3.25 minutes
13miles in 3 minutes and 15 seconds
= 13 miles / 3.25 minutes
= 4 miles / 1 minute
every minute Jose ran 4 miles
then:
4 miles is a 1 minute
1 mile is a T minutes
T = 1*1/4
T = 1/4 minute
1 minute = 60 secomds
1/4 minute = 60*1/4 = 60/4 = 15 seconds
