Yes one gram is equal to 1000 milligrams
Answer: 0.547
Step-by-step explanation:
As per given , we have
Population mean = 
Population standard deviation= 
Sample size : n= 36
We assume that number of apps used per month by smartphone owners is normally distributed.
Let
be the sample mean.
Formula : 
The probability that the sample mean is between 19.5 and 20.5 :-

[using standard normal distribution table for z]
Hence, the required probability = 0.547
Answer:
Q = P - n(x/100)
Step-by-step explanation:
P is the total number of lace edging, n is the number of times the length x is cut from P, and Q is the remnant of the reduction.
So the number of x length is subtracted from P and must be converted to meters (since it is in centimeters) to get Q. That is;
Q = P - n(x/100)
Answer:
Multiplying by 1 does not change the ratio
Step-by-step explanation:
Multiplying a/b by c/c gives the equivalent ratio (ac)/(bc) because c/c is 1, the multiplicative identity element. Multiplying by 1 does not change the ratio.
