Answer:
Number of student (not Bike) = 12
Number of student (Bike) = 84
Total student = 96
Step-by-step explanation:
Given:
Probability of student have bike = 7/8
Computation:
Assume;
Number of student (Bike) = a
Number of student (not Bike) = b
So,
a-b = 72
So,
a / (a+b) = 7/8
8a = 7a + 7b
a = 7b
So,
a-b = 72
7b - b = 72
6b = 72
b = 12
Number of student (not Bike) = 12
Number of student (Bike)
a -12 = 72
a = 84
Number of student (Bike) = 84
Total student = 84 + 12
Total student = 96
Answer: 10;6
Step-by-step explanation:
12+8=20;10+10=20
24-12=12;6+6=12
The point-slope form:
We have
Therefore
the point = (2, 1)
the slope = 7
The slope 
7 units up and 1 unit right.
-------------------------------------------------------------------------------
Other method.
It's the slope-intercept form.
for x = 0 → y = 7(0) - 13 = 0 - 13 = -13 → (0, 13)
for x = 2 → y = 7(2) - 13 = 14 - 13 = 1 → (2, 1)
Answer:
There are 16 bowls
Step-by-step explanation:
Number of bowls = x
Total grapes added = 12 x 8 = 96
The average increased by 6
So 96/6 = 16
There were 16 bowls of grapes on the table
OR
12 x 8 = 96
96/6=16
