Answer:
72
Step-by-step explanation:
c=9
d=8
cd = c*d
substitute in what they give you the variables equal to
cd=9*8=72
Answer:
Item (D)
Step-by-step explanation:
In the stratified random sample we would divide our population into homogeneous groups / strata and then we randomly select the individuals in each group / stratum.
In general, when comparing with the simple random sample, we realize that stratified random sampling has the advantage of increasing accuracy and decreasing variability.
In the question, we have two strata: female students and male students. On each one of the strata, a random sample of 25 names was made in the list.
Answer:
10 pounds of strip lion
Step-by-step explanation:
1. find total percentage of loss (trim loss % + cooking loss %) = 60% + 20% = 80%
2. find how many pounds make up 80% of 50 lbs. = 100%
(50 lbs. = 100%) / 100 = (0.50 = 1%) * 80 = (40 lbs. = 80%)
3. find # of pounds left to serve (total weight of strip loin - total weight of loss) = 50 lbs. - 40 lbs. = 10 lbs.
We will subtract 2y^2-3y-5 from y^3-6y^2+5y
This is written as follows:
y^3-6y^2+5y - (2y^2-3y-5)
note that the subtraction means that some signs would change as follows:
y^3-6y^2+5y - 2y^2+3y+5
Now we will subtract the coefficients of like terms as follows:
y^3 - y^2(6+2) + y(5+3) + 5
= y^3 - 8y^2 + 8y + 5
Answer:
Total time = 19 minutes.
Step-by-step explanation:
Given the following data;
Time to shower = 720 seconds
Time to eat breakfast = 420 seconds
To find the total time in minutes;
Total time = 720 + 420
Total time = 1140 seconds
We know that 60 seconds equals a minute.
Total time = 1140/60
Total time = 19 minutes.
Therefore, it will take Andrew 19 minutes to take a shower and eat breakfast.
