Answer:
CV = coefficient of variation = 0.761
Step-by-step explanation:
The coefficient of variation is defined as the standard deviation divided by the mean of a population, which in this case,
standard deviation = 15.6
mean = 20.5
CV = coefficient of variation = 15.6/20.5 = 0.761
Note that if the 16 values form a sample (i.e. not the entire population), the above result is an estimate of the CV.
24 divided by 8 equals 3, so Joel has 3 soccer trophies.
Answer:
You want to use 25 x 1.2, because that ensures that you earn a 20% profit. The final answer is 30.
Step-by-step explanation:
Please mark BRAINLIEST!
$27 x 18 students = 486 actual cost.
$30 x 10 students = 300 estimated total cost using compatible numbers.
$20 x 20 students = 400 estimated total cost using compatible numbers. (better option because it is nearer to the actual cost)
Compatible numbers are numbers that can easily be multiplied or divided using mental computation.
Compatible number for 27 and 18 can be: 30 and 20 OR 20 and 20 OR 30 and 10 OR 20 and 10.
However, there is a rule in multiplying the compatible numbers, when one number is increased the other number must be decreased.
So 27 can be increased to 30; while 18 can be decreased to 10 to get a product of 300.
27 can be decreased to 20; while 18 can be increased to 20 to get a product of 400.
