Avoid repeating the question as it can be perplexing.
Given 100 cookies and 20 brownies,
What is the highest number you can divide them equally by?
To find the greatest common factor,
Factor them:
100 = 2*2*5*5
20 = 2*2*5
Thus, the greatest common factor, which is shared between them, is 2*2*5 or 20.
Calculating further, 100/20=5
20/20=1
This means there are 20 groups, each containing 5 cookies and 1 brownie.
20 groups
Answer:
At a confidence level of 90%, the margin of error is calculated to be 0.5133 grams.
Step-by-step explanation:
The formula for margin of error (E) is: (critical value × sample standard deviation) ÷ sqrt(n)
The sample standard deviation is 1.5 grams.
A 90% confidence level translates to 0.9.
Significance level is determined as 1 - C, which equals 1 - 0.9 resulting in 0.1 or 10%.
The sample size (n) is 25.
Degrees of freedom are calculated as n - 1, which is 25 - 1 equaling 24.
The critical value (t) for 24 degrees of freedom at a significance level of 10% is found to be 1.711.
Using these values, we calculate: E = (1.711 × 1.5) ÷ sqrt(25) = 2.5665 ÷ 5 = 0.5133 grams.
