The value of 
.
Solution:
Given equations:
7x + 2y = 57 ---------- (1)
x + 2y = 5 ---------- (2)
Subtract 2y from both sides of the equation (2).
x = 5 – 2y ---------- (3)
Substitute equation (3) in equation (1).
7(5 – 2y) + 2y = 57
35 – 14y + 2y = 57
35 – 12y = 57
Subtract 35 from both sides of the equation.
–12y = 22
Divide by 12 on both sides.
Substitute y value in equation (3).
Hence the value of .
Answer:
Slope = 3
Step-by-step explanation:
The formula for calculating the slope is expressed as:
m = y2-y1/x2-x1
From the coordinate, x1 = 0 y1 =0 x2 = 5, y2 =15
m = 15-0/5-0
m = 15/5
m = 3
Hence the slope is 3
Answer:
Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.
Step-by-step explanation:
The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes. As more trials are conducted, the experimental probability generally gets closer to the theoretical probability
