Describe the sample space for this problem: 1200 students at a certain school, all with equal probability of being selected on a random draw.
Which outcome (or outcomes) of the sample space compose the event?
Sophie wins the bike. The chances that that will happen are 1/1200, or 0.00083...
First add 7d to both sides:
-22 = 11d
Now divide by 11 both sides
-2 = d
You can work on either side of the equation, I used the right side for the variables because it was easier to add to positive numbers than dealing with negative numbers on the left side:
-7d -4d = 22
-11d =22
d = -2
either way you get the same answer :)
Answer:
Each kid will get 2.5 submarine sandwiches
Step-by-step explanation:
First apply the exponent: 3 ^ 2
9
Then we do the multiplication: 4 * 9 = 36
Finally we add
8 + 36 = 44
I have included a picture. In the picture you will find the work and final answer.
