Step-by-step explanation:
A random sample of 650 power cells is tested and the average lifetime of this sample is found to be 315 hours.
The 315 hours is the value of a: statistic
A statistic is defined as a characteristic of a sample. It is used to estimate the value of a population parameter.
Just like here where a random sample of 650 power cells were taken for a test. And 315 hours is an example of a statistic.
Answer:
24 bags can be made from three 5 pounds bags.
Step-by-step explanation:
Given that:
Three 5 pound bags are donated.
Total weight of bags = 3*5 = 15 pounds
We know that:
1 pound = 16 ounces
15 pounds = 16*15 = 240 ounces
A bag weighs 10 ounces.
Number of bags = 
Number of bags = 24 bags
Hence,
24 bags can be made from three 5 pounds bags.
Scale factor: f=0.5
AB=2.2
LM=?
LM=f x AB=0.5 x 2.2 →LM=1.1
The length of LM is 1.1
Answer:
-148/3 or -49.3
Step-by-step explanation:
37^2 = 35^2 + x^2
Pythagorean Theorem.
37(squared) equals 35(squared) + x(squared)
•subtract 35(squared) from both sides
•take square root of both sides
