Answer:
0.395
Step-by-step explanation:
The computation of the probability that none of the three shoppers purchased electronics is shown below:
So, first we have to determine the number of shoppers without considering the purchase i.e
= Total number of shoppers - electronics
where,
Total number of shoppers = Offices supplies + electronics + clothing + beauty supplies - electronics
= 18 + 25 + 40 + 12 - 25
= 95 - 25
= 70
Now the probability is
=
= 0.395
I think it’s: Concurrency of Angle Bisectors of a Triangle.
Use the difference of squares factor rule to get
4x^2-9y^4
(2x)^2-(3y^2)^2
(2x-3y^2)(2x+3y^2)
The final answer is choice C
Note: the order of the factors does not matter
Answer:
152£
Step-by-step explanation:
1. 1/3 of the coins is 255/3=85 85coins is worth 1£
2. 110 of the coins are worth 50p
3. to figure out hos many 20p coins
total number of coins - number of 1£ coins - number of 50p coins
255-85-110=60
60 of the coins are worth 20p
4 add everything togheter
85£ from first
110/2=55£ from second
60 coins are worth 20p
5 coins make 1£
60/5=12£
5. add everything 85+55+12=152£
