Angle PQR=90 degrees.
cos 52=PQ/14.72
PQ=14.72 x (cos 52)
PQ= 9 cm to the nearest cm
Answer:
3/4
Step-by-step explanation:
Difference means subtraction
12/8 - 3/4
We need a common denominator of 8

Answer: The variance of their weights = 9,752,155,009 kg.
Step-by-step explanation:
- The variance is the square of the standard deviation . it measures the spread between data values in a data set.
So if standard deviation of 10 subjects = 98753 kg
Then, variance = 
Hence, the variance of their weights = 9,752,155,009 kg.
Since the denominators are the same, just subtract the numerators.
The answer is 3/10.
