Yes, you did this right. 5 if the GCF of 15 and 5
all you have to do is find the GCF and then divide so you can get your new inside values with the gcf outside the parentheses.
Answer: Stratified sampling
Step-by-step explanation:
Stratified sampling is a particular kind of random sampling technique.
Here , the researcher splits the entire population into distinct groups known as strata.
Then he draw a sample by taking participants from each strata and continue his work on sample.
As per given ,
Researcher = Sneha
Strata = Each floor
Since from each floor she randomly selects 2 rooms and inspects them and then takes the average of these scores.
Therefore , Sneha used the Stratified sampling technique.
Answer:
-58
Step-by-step explanation:
-|123+(-1)|/2-(-3)
-|122|/2-(-3)
-122/2-(-3)
-61-(-3)
-58
7*(60+3)=7*60+7*3= 420+21=441
When writing equivalent expressions, there are often several possible orders in which to simplify them. However, they will all take you to the same result as long as you do not make a mistake when using the properties. In this example, you will distribute the outer exponent first using the Power of a Product Property.
