80 because you are multiplying 10×8
Step-by-step explanation:
this is an improper fraction to make it mixed you have to find how many 20s are in 23
yea only one
so 1 is the whole number
then it is 1 3/20
you can again make it improper by multiplying denominator by 1 and adding 3
60/45 = $0.75
It costs $0.75 to make each valentine so if they were sold for 75 cents then that would result in a profit of zero if all the valentines were sold.
This is an approximately bell-shaped distribution. The highest bar is in the center, with height = 12. Just to its left and right are bars of heights 6 and 5. At the extremes are bars of heights 2 and 1.
If the highest bar was on the left, it would be skewed left (and if it was on the right, skewed right). A uniform distribution would more or less have the same height level over all the bars.
Answer:
Step-by-step explanation:
<u>Key skills: Exponents + Fractions</u>
Use the negative exponent property. If your number is x^-y then it would be the same as 1/x^y
3^-4 is the same as 
3^4 is 81, so your answer would be 1/81.
Hope you have a nice day and understood this!
