Answer:
C) 8.5%
Step-by-step explanation:
First, subtract the cost after tax to the cost before tax.
84.63 - 78.00 =
6.63
Then, divide the original cost from this
6.63 / 78.00 =
0.085
When reading percentages on a calculator, we know this is equivalent to 8.5%
Hope this helps! :)

Answer:
B) μD = 0.60 ± 0.10(1.397)
Step-by-step explanation:
The confidence interval is given by:
Where
MD=60
n=9
df=n-1=8
Then the confidence interval is
μD=0.60±1.397*(0.3/√9)
μD=0.60±0.10*(1.397)
Answer:
Part A: 2 - 10
The 5 is the width in metres, the x is the extension in metres, and the 8 is the length in metres.
Step-by-step explanation:
5(x + 8) Distribute the properties first. (5)x +8(5)
Then multiply them. 5x + 40.
Next we want to isolate x, so we will subtract 40 to cancel out the +40. We do this on both sides to balance it.
5x + 40 = 0
5x + 40 - 40 = 0 - 40
5x = -40
Next we will divide by 5 to cancel out the multiply by 5.
5x/5 = -40/5
x = -8
So an equivalent expression would be anything that equals an answer of -8, such as 2 - 10.
