Answer:
The question is incomplete, but the step-by-step procedures are given to solve the question.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
That is z with a pvalue of 
, so Z = 2.575.
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M.
The upper end of the interval is the sample mean added to M.
The 99% confidence interval for the population mean amount of beverage in 16-ounce beverage cans is (lower end, upper end).
Hi, this is the notation for inclusion of all real
numbers.
We can also state numbers which are positive or negative with a sign on top of the R notation like so:
Answer:
22
Step-by-step explanation:
<h2>
—Math</h2>
√(x+3) –4 = 1
√(x+3) = 1 +4
√(x+3) = 5
x + 3 = 5²
x = 25 –3
x = 22
Answer:
neither
Step-by-step explanation:
because the square root is not whole number and neither is the cube root of 165. so it is neither
Answer:
Front: 33 ft
Back: 66 ft
Step-by-step explanation:
Let w be the width of the front yard
½[w + 2w]×2w = 3300
3w² = 3300
w² = 1100
w = 33.1662479036
w = 33 ft
2w = 66 ft
