Question seem incorrect because 60%,50% and 20% sum up to more than a 100% therefore we've made a little correction
Answer:
0.8
Step-by-step explanation:
Probability = number of favorable outcomes/number of outcomes
Given that 30% are entertained by reading books
50% are entertained by watching TV
20% are entertained by reading books and watching TV
The probability that a person will be entertained by books or TV =
30/100+50/100= 3/10+5/10
=8/10
=0.8

Answer:
a) 10 pieces of 2/3 pound can be made.
b) 0.54 pounds of wax is left over.
Step-by-step explanation:
Total amount of clear wax available =
pounds
So, the maker has in total 4.5 pounds of wax
Now, The weight of each piece =
pounds
To find the number of pieces that can be made out of 4.5 pounds of wax,
let that number = n
So, 
or, n = 
So, nearly 6 pieces can be made completely out of the clear wax
Left over amount of wax = Total weight - Weights of the pieces made
= 4.5- 6(0.66)
= 0.54 pounds
Hence, 0.54 pounds of wax is left over
5(x-2) or 5x-10 are both correct
Answer:
Rate = 10.4%
Step-by-step explanation:
Given :
P = $30000
A = $42520
Interest earned = 42520 - 30000 = $12520
Time = 4years
<em><u>Find R </u></em>


Round to 1 decimal place, Rate = 10.4%
