Answer:
girls = 125
boys = 87
Step-by-step explanation:
Total number of students in the 8th grade class = 212
Let g represent girls and b represent boys
Number of girls, g = 2b -49
Note that boys and girls in the class give a total of 212
So,
g + b = 212 ....eq 1
Slot in the value of g in the equation
2b - 49 + b = 212
2b + b - 49 = 212
3b - 49 = 212
Add 49 to both sides
3b - 49 + 49 = 212 + 49
3b = 261
Divide both sides by the coefficient of b which is 3
b = 87
Now that we've found the number of boys, let's find that of girls
We will slot in the value of b in eq 1
g + 87 = 212
Subtract 87 from both sides
g + 87 - 87 = 212 - 87
g = 125
So the number of boys is 87 and the number of girls is 125
Answer:
The answer is %2,4
Step-by-step explanation:
Residents can press on 10 different button choice when they enters the elevator. Number of components for the sample space for the event is
There are 8 different possibilities that 3 consecutive buttons are pressed those are:
-1,2,3
-2,3,4
-3,4,5
-4,5,6
-5,6,7
-6,7,8
-7,8,9
-8,9,10
When the pressing order doesn't matter, those buttons can be pressed 3 different ways for each possibility.
The probability is:
