21/10+5/10
Add nominators since denominators are the same.
26/10
Or 2 6/10 as a mixed number.
Answer:
(0.0706, 0.1294)
Step-by-step explanation:
Confidence interval of a proportion is:
CI = p ± CV × SE
where p is the proportion,
CV is the critical value (z score or t score),
and SE is the standard error.
The sample is large enough to estimate as normal. For 95% confidence level, CV = z = 1.96.
Standard error for a proportion is:
SE = √(pq/n)
SE = √(0.1 × 0.9 / 400)
SE = 0.015
The confidence interval is:
CI = 0.1 ± (1.96)(0.015)
CI = (0.0706, 0.1294)
Round as needed.
Answer:
<em>58%</em>
<em>Step-by-step explanation:</em>
<em>Just do 0.576923 times 100% & you should get 57.6923% than round because it says nearest whole number so that's how your answer is 58% :)</em>
Answer:
undefined
Step-by-step explanation:
6 is the correct answer because the thousandths place is a number of 5 and above, which means you move the hundredths place value up by 1. Because the hundredths place value is 9, moving it up by 1 would mean that 0 becomes the place value for the hundredths place and one is added to the tenths place. And because 9 is also the place value of the tenths place, the tenths place becomes 0 and 1 is added to the ones place.
