given that an auto parts store is examining how many items were purchased per transaction at the store as compared to their online website
The data is shown below:
Frequency Frequency*Midpt
Midpt Online Total Online Total
1-3 2 40 147 80 294

7-9 8 15 32 120 256
10-12 11 5 18 55 198
120 300 555 1263
Thus we find total items purchased on line = 555
and total items overall purchased = 1263
Hence the probability that a randomly selected item was purchased online

Hi again!
Your answer is D. 5/42. Here's how we got that.
1) Multiply across. 1 * 5 / 6 * 7.
2) 1 * 5 = 5. 6 * 7 = 42.
Put solved form of 1 * 5 and 6 * 7 into fraction.
5 / 42.
Hope this helps! ☺♥
To visualize better, look at it like this:
First, see if you can simplify 3/2. You can't, so leave it like that.
The rule for exponents is you subtract the exponent from the bottom (r) from the exponent on the top ()
Put that on the top, and you get
(-4) to the 4th power is 256
-4 to the 9th power is 262144
Answer:
The negative of a negative is a positive. You can rewrite the equation as -3+1. So, the answer is -2.
