Derek will pay $625.25 less than the original prize
<u>Step-by-step explanation:</u>
The selling price of the computer=$610
The selling prize is 1/5 of its original prize
Derek has a 10% off coupon
Let the original prize of the computer=x
selling prize=x-x/5
4x/5=610
4x=3050
x=3050/4=762.5
the difference in the original prize and the prize at which Derek bought the computer=x-9x/50
=41x/50
Derek will pay $625.25 less than the original price for the computer.
The question is an illustration of probability. The probability of an event is the calculated by dividing the required outcomes by the possible outcomes.
The probability that M will be in the shaded region is 0.64
The given parameters from the question are:
Side length of the big square = 10 cm
Side length of the small square = 6 cm
<em>See attachment for diagram (not drawn to scale)</em>
First, we calculate the area of the squares using:
The area of the big square is:
----- this represents the possible outcomes
The area of the small square is:
The area of the shaded region is the difference between the areas of the big and small squares:
----- this represents the possible outcomes
<u>So, the probability that M is on the shaded area is:</u>
--- i.e. the shaded area divided by the total area
