Answer:
A. 13%
Step-by-step explanation:
let's suppose there's 1000 bars of chocolate in general
70 % dark = 700 dark choco bars
30 % milk = 300 milk choco bars
20 % have nuts = 200 bars have nuts
80 % don't have nuts = 800 bars don't have nuts
if 90 % of dark chocolate bars don't have nuts, that means 630 dark chocolate bars don't have nuts, but 70 have nuts
200 bars in general have nuts, if only 70 dark chocolate bars have nuts,
200 - 70 = 130
130 = 13%
Answer:
terminating
Step-by-step explanation:
Answer:
Step-by-step explanation:
so the least common denominator is 12, so:
multiply 3/4ab by three, which equals: 9/12ab
9/12ab-5/12ab = 4/12ab, or 1/3ab
<u>Answer-</u>
A 95% confidence interval for the true percent of movie goers is 36.41% to 44.25%
<u>Solution-</u>
Given,
n = 600 (sample size)
x = 252 (number of people who bought)
Confidence interval = 95%, so z = 1.96
We know that,
where,
M = sample mean
Z = Z statistic determined by confidence level
SE = standard error of mean
Calculating the values,
from the tables
Putting all the values in the formula,
Answer:
x = 1/4
Step-by-step explanation:
16 = 2 can be written as 
= 2
(
)^x = 2^1
if bases are the same we can create this equation: 4x = 1
x = 1/4
