Answer:
The probability is 2/5.
Step-by-step explanation:
4/5 is the probability of not getting a 5
1/2 is the probability of flipping heads
4/5x1/2 = 4/10 = 2/5
True. A regular quadrilateral has 4 equal sides.
225 serves because you need to set up a proportion. The proportion is 2/5=90/x then solve for x by cross multiplying, which gives you 450=2x. Then divide 450 by 2 which gives you 225. Work shown in the attached picture.
To find the amount increase in price, you will calculate what 60% of the $38 is by multiplying 0.6 and 38
0.6 x 38 = $22.80 is the amount of increase.
The retail price is found by adding the increase to the cost.
$38 + $22.80 = $60.80.
