Alpha = 0.05
95% confidence interval:
Putting the values, we get,
Answer:
n=25
Step-by-step explanation:
so you take 12.5 divide that by 0.5
and your answer would be 25
The slope is 1.
The y-axis or the y-intercept is (0, 5)
Answer:
$18.15
Explanation:
In this case, we can add the percentages because they are taken of the same number.
The state sales tax, 4.6%, will be taken of $220, the purchase price. The county sales tax, 3.65%, will also be taken of $220, the purchase price. Since they are being taken of the same number, we can add the percentages:
4.6+3.65 = 8.25%
Now we can take 8.25% of 220:
8.25% = 8.25/100 = 0.0825
0.0825(220) = $18.15
