Answer:
6x¹⁰ - 96x²
6x²(x⁸ - 16)
B) 6x²(x⁸ - 16)
6x²[(x⁴)² - 4²]
6x²[(x⁴ - 4)(x⁴ + 4)]
6x²(x⁴ + 4)[(x²)² - 2²]
6x²(x⁴ + 4)(x² - 2)(x² + 2)
Answer:
28 biscuits
18 packages of pemmicans
4 packages of butter and cocoa
Step-by-step explanation:
We are given percentage of total daily calories for each item.
Since total number of calories per person each day is 5600,then;
Number of calories from biscuit daily = 40% × 5600 = 2240 calories
Since there are 80 calories per biscuits, then number of biscuits = 2240/80 = 28 biscuits
Number of calories from pemmican daily = 45% × 5600 = 2520 calories
Since there are 140 calories per package, then number of packages of pemmican = 2520/140 = 18 packages of pemmicans
Number of calories from butter and cocoa daily = 15% × 5600 = 840
Since there are 210 calories per package, then number of packages = 840/210 = 4 packages of butter and cocoa
Answer:
The correct selections are:
B) After the donation collection period, compare the average or total amount collected from each of the two treatment groups.
C) A placebo is not being used
F) Randomly select 500 donors to receive the literature and 500 donors to receive the phone call.
Step-by-step explanation:
What this question requires from you, is to identify the correct characteristics of the study described. Let us explain why each of the selections was made.
B) After the donation collection period, compare the average or total amount collected from each of the two treatment groups: The purpose of the study is to determine the difference in the effectiveness of two methods of fundraising. Therefore at the end of the study, the average total amount raised from each group will be compared to determine which was more effective.
C) A placebo is not being used: Placebos are sham treatments used in a control group without their knowledge. The placebos do not produce any effect similar to the results anticipated the actual treatment. Here, no group is given sham treatment, there is no "control" group given placebos hence placebos are not used.
F) Randomly select 500 donors to receive the literature and 500 donors to receive the phone call: To remove any form of bias in the study, the selection of the groups is done at random, and the number of participants in each group is the same, so as to maintain uniformity during the comparison.
