Answer:
It lies between the numbers 4 and 5
Step-by-step explanation:
If John has 17 leaves and 4 cages then he should put 17/4, or 16/4+1/4 which is 4+0.25, or 4.25 in each cage.
Answer:
d. 0.0023
Step-by-step explanation:
Calculation for the probability of getting a sample average of 1.8 or less
Using this formula
z score =(X-mean)/Standard errror
Where,
Standard error =Standard deviation/√(n)
Let plug in the formula
P(Xbar<1.8)=P(Z<(1.8 hours per day -2.2 hours per day)/(2 hours /√(200))
P(Xbar<1.8)=P(Z<-0.4/(2/14.14))
=P(Z<-0.4/0.1414)
=P(Z<-2.83)
Now let find the Z score of P(Z<-2.83) using the z table
P=0.0023
Therefore the probability of getting a sample average of 1.8 or less is:0.0023
Speed=15 m/s
1 hour=60 minutes
60 minutes=60 minutes (60 seconds/1 minute)=3600 seconds.
15 m/s=(15 m/s)(1 mile / 1609 m)(3600 s/1h)=33.56... miles/hour≈
≈33.6 miles/hour.
Answer: the speed in miles per hour would be 33.6 miles/hour
3:8 can also be written as 3/8
12:32 can also be written as 12/32
So thus 3:8 is equivalent to 12:32
