So the original price is "x".
the discounted price by 10% is P(x) = 0.9x.
the price minus a $150 coupon is C(x) = x - 150.
so, if you go to the store, the item is discounted by 10%, so you're really only getting out of your pocket 90% of that, or 0.9x, but!!! wait a minute!! you have a $150 coupon, and you can use that for the purchase, so you're really only getting out of your pocket 0.9x - 150, namely the discounted by 10% and then the saving from the coupon.
C( P(x) ) = P(x) - 150
C( P(x) ) = 0.9x - 150
To the left of the decimal point needs to be somewhere between 1 and 9 (one place). 983 in scientific notation would be 9.83 x 10^2. Do you understand how i got that? I got the 10^2 because i am moving the decimal point over two places to the left. If i move the decimal point to the right, then the exponent would be negative. Example:
0.00983 in scientific notation would be 9.83 x 10^-3 because i moved the decimal point three places to the right.
The number of people that speak only spanish = 6
<h3>How to Interpret Venn Diagrams?</h3>
We are given;
Total number of people surveyed = 50
31 speak French 2 speak French, German and Spanish.
4 speak French and Spanish but not German.
7 speak German and Spanish.
8 do not speak any of the languages.
All 10 people who speak German speak at least one other language.
Thus;
From the Venn diagram;
Number of people that speak only French and German = 10 - 5 - 2 - 0 = 3
Number that speak only spanish = 50 - 22 - 3 - 2 - 4 - 5 = 6
