Answer:
9 (5e - 3f)
Step-by-step explanation:
45e -27f
45e = 9*5*e
27f = 9*3*f
The common factor is 9
9*5*e - 9*3*f
9 (5e - 3f)
Forget the '34' part of 8:34 and the '18' minutes from 3 hours and 18 minutes for now.
Just add 3 hours on to 8, to get 11. Then, bring back the 34 and 18 and add them together. 34 + 12 = 52. Now put that 52 on the end of the 11, and you get 11:52 as the end time.
Answer: Probability that a shopper buys shoes and a book is 0.02.
Step-by-step explanation:
Since we have given that
Event A : Buying a pair of shoes
Event B: Buying a book
Since A and B are independent events.
Probability that a shopper buys shoes i.e.
P(A) = 0.20
Probability that a shopper buys a book i.e.
P(B)=0.10
So, we need to find the probability that a shopper buys shoes and a book is given by

Hence, Probability that a shopper buys shoes and a book is 0.02.
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
