Answer:
The correct option is;
A). Randomized block design
Step-by-step explanation:
In a randomized block design the experimental units or subjects of the experiment are separated into subgroups known as blocks with the property that the the variability (difference) of the parameters within the blocks are lesser than the variability between block, such that the treatment of the research or experiment are assigned differently to each block
The groups can therefore comprise of the following;
Group 1
15 men and 15 women to perform water aerobics for 30 minutes twice a week
Group 2
15 men and 15 women to perform water aerobics for 60 minutes once a week
Therefore, the effect of the experiment will be much less attributed to gender than to the durations of the water aerobic exercise.
Answer:
I think the answer is C
Step-by-step explanation:
If you have a normal ginger bread cookie, its full size would be 100%. So, if you add the first 25%, 1.25%
Answer:
72
Step-by-step explanation:
We are assuming that all girls in the group bought the same number of items.
Therefore, we need to find the highest common factor of 72, 144 and 216.
HCF
72 = 2 * 2 * 2 * 3 * 3
144 = 2 * 2 * 2 * 2 * 3 * 3
216 = 2 * 2 * 2 * 3 * 3 * 3
The product of the emboldened numbers is the highest common factor.
That is:
2 * 2 * 2 * 3 * 3 = 72
Therefore, the largest possible number of girls in the group is 72.
Answer:
False
Step-by-step explanation:
Based on the information given we can calculate the finance charge of Maryanne’s by simply multiplying her average daily balance which is the amount of $755 times her monthly periodic rate which is 0.0185.
Hence, Maryanne's finance charge is calculated by using this formula
Finance charge=Average daily balance*Monthly periodic rate
Let plug in the formula
Finance charge= $755* 0.0185
Finance charge= $13.97
Therefore Maryanne's finance charge will be $13.97
<span>In order to calculate how long it will take Jamie to finish painting the fence, you should divide the length of the fence by the rate at which Jamie paints. Thus, if the fence is 119.5 yards long and Jamie paints on average 4.78 yards per hour, we divide 119.5 by 4.78 and get the answer - 25 hours. We can double check our work by multiplying Jamie's painting rate by the time, so if Jamie paints 4.78 yards per hour for 25 hours, he will paint all 119.5 yards.</span>
