Answer:
Step-by-step explanation:
Given
of child's age
Solving (1):
Determine the cost function.
Represent the years as y.
So, we have:
* y
Convert 25 cents to dollars.
So, we have:
The cost amount is then:
--- This is the cost function
Solving (b): Cost of 9 years old.
In this case;
Substitute 9 for y in
--- This is the cost for a child of 9
1/2 can be rewritten as 3/6, and 2/3 can be rewritten as 4/6 (find the lowest common denominator and in this case it is 6 because 2x3=6). 3/6+4/6=7/6. 12 can rewritten as 24/6, so do 24/6 - 7/6 and you answer is 17/6.
Answer:
72 mins
Step-by-step explanation:
12 mins = 4 tortillas
1 tortilla = 3 mins
3x24=72
72 mins
The die can land in 6 different ways.
Only one of them is a 2.
So the probability of rolling a 2 on any roll is 1/6 .
In a large number of rolls, you expect roughly 1/6 of them to be a 2.
In 108 rolls, you should expect a 2 somewhere around
(108/6) = 18 times.
