100% - 20% = 80%.
400 is 80% of what number?
Let n = the original price.
400 = 0.80n
400/0.80 = n
€500 = n
Understand?
Answer:
around 88
times 5 11 times to get 55 so times 8 11 times for approximate answer
B (smallest two digit even number) = 10 <=== B
AB = 840
A = 840/B
A = 840/10
A = 84 <=== A
C - A = 816
C - 84 = 816
C = 816 + 84
C = 900 <===== C
Answer:
i think if its on a graph
Step-by-step explanation:
Answer:
b. 2-independent sample t-test
Correct for this case is the best test since the result from each group are independent and we can compare the sample means between th two groups
Step-by-step explanation:
For this case the intention is try to test if scores on a test of science achievement differ for female and male 8th grade students. let's analyze the possible options for this case:
a. 2-dependent sample t-test
False is not possible since the nature of the gender is not possible to conclude tha the results from boys and girls are dependent
b. 2-independent sample t-test
Correct for this case is the best test since the result from each group are independent and we can compare the sample means between the two groups
c. Correlation
False we can't compare the means of interest with a correlation coefficient since that's not the purpose of the study
d. 2-way ANOVA
False we have just one variable between two groups so is not possible to apply a 2 way ANOVA
