Answer:
<em>1) 6%</em>
<em>2) $1,689.35</em>
Step-by-step explanation:
1) Given the following
Sales tax = $64.80
Price of the computer = $1080
Required
rate of sales tax
Using the expression
x% of 1080 = 64.80
x/100 * 1080 = 64.80
10.80x = 64.80
x = 64.80/10.80
x = 6%
<em>Hence the rate of sales tax is 6%</em>
<em></em>
2) Given the following
Price of the car = $25,990
Tax rate = 6.5%
Sales tax charged = 6.5% of $25,990
Sales tax charged = 6.5/100 * 25,990
Sales tax charged = 6.5 * 259.9
Sales tax charged = $1,689.35
<em>hence the sales tax being charged is $1,689.35</em>
Answer:
(x-1)!
Step-by-step explanation:
lets say you want to sit x people around a table you would do x!. but since it doesn't count if you rotate the table you have to divide it by x, so the answer is x!/x = (x-1)!
Answer:
b)
Step-by-step explanation:
we can get it by Pythagoras theorem
9^2+7^2=x^2
81+49=130
x=√130

Answer:
C.I = 0.108 ± 0.022
Step-by-step explanation:
In this case, we are given a symmetric confidence interval, and the sample proportion p', is derived by finding the average of the two values.
Therefore, the sample proportion will be:


= 0.108
p' = 0.108
To find the margin of error, we have:
M.E = ½ * length of confidence interval
Where length of confidence interval = 0.130 - 0.086
= 0.044
Therefore,

Margin of error = 0.022
The confidence interval is expressed as:
p' ± M.E
= 0.108 ± 0.022
