Area = length x width
that means
width = area / length
divide 103 1/8 by 12 1/2
I get 8 1/4
Answer:
1/8
Step-by-step explanation:
Probability of pulling a nickel the first time: 5/10
Probability of pulling a nickel the second time: 5/10 (remember that you are replacing)
Probability of pulling a dime the third time: 5/10
Total probability: 5/10 * 5/10 * 5/10 OR 1/2 * 1/2 * 1/2 = 1/8
im pretty sure this is the answer! i hope this helps! <3

Answer: -0.196</h3>
======================================================
Explanation:
We're conducting a one proportion Z test.
The hypothesized population proportion is p = 0.53, which is not to be confused with the p-value (unfortunately statistics textbooks seem to overuse the letter 'p'). Luckily this problem is not asking for the p-value.
The sample population proportion is
phat = x/n = 41/79 = 0.518987 approximately
The standard error (SE) is
SE = sqrt(p*(1-p)/n)
SE = sqrt(0.53*(1-0.53)/79)
SE = 0.056153 approximately
Making the test statistic to be
z = (phat - p)/(SE)
z = (0.518987 - 0.53)/0.056153
z = -0.19612487311452
z = -0.196
Which is approximate and rounded to 3 decimal places.
