Answer:
Step-by-step explanation:
Given that a cola-dispensing machine is set to dispense a mean of 2.02 liters into a bottle labeled 2 liters.
Std deviation =0.015 litres
X- litres contained in a bottle is N(2.02, 0.15)
Z score is obtained as
a) probability a bottle will contain between 2.00 and 2.03 liters
=P(2<x<2.03) = P(-1.33<Z<2)
= 0.4082+0.4772
=0.8854
b) P(X<2) = P(Z<-1.33) =0.5-0.4082 = 0.0918
c) 2% of containers
|z|<0.11
X lies between 0.6883 and 3.352 l

Answer:
300 phones the company activated in one minute
As per unitary method, calculation been done to find the value of single unit from the value of multiple units.
So, she is dividing the total number of phone activated by number of minutes taken to activate to find phone activate in one minute.
Step-by-step explanation:
Here is the correct question: Meg wants to find how many phones the company activated in one minute. Explain why meg can use 15000 divided by 50 to find the answer.
As per unitary method, calculation been done to find the value of single unit from the value of multiple units.
Therefore, in the above question Meg knew the number of total phone activated by company in 50 minutes, which is 15000.
Now, she want to find how many phones the company activates in one minute.
So, she is dividing the total number of phone activated by number of minutes taken to activate to find phone activate in one minute.
Phones the company activated in one minute=
∴ 300 phones the company activated in one minute.
Answer:
Step-by-step explanation:
convert 1 3/4 into improper fraction: 7/4
we got this from 4 × 1 = 4, then 4 + 3 = 7
the denominator stays the same
we need to subtract the amount that he has left from
the total amount:
make the number 3 have the same denominator as 7/4
convert 5/4 into a mixed number:
the numerator has to be the same, so how many lots of 4 can go into 5 without a remainder? it is 1
4 × 1 = 4
1 is left over, so the numerator is 1
4 + 1 = 5
