Y=5/2x+5 because the slope is 5/2 and the y-intercept is 5
Answer:
A it is 10% higher than the theoretical probability
Step-by-step explanation:
Plug 4 for x and solve.
y = -3/4 * 4 + 3
y = -12/4 + 3
y = -3 + 3
y = 0
So the missing coordinate is 0.
To solve the equation, you need to isolate/get the variable "P" by itself in the equation:
P - 3 = -4 Add 3 on both sides to get "P" by itself
P - 3 + 3 = -4 + 3
P = -1
PROOF
P - 3 = -4 Plug in -1 for P
-1 - 3 = -4
-4 = -4
Answer:
120 pounds
Step-by-step explanation:
Since the new cost is 144 pounds and this is 20% more, this is 120% of the original price. Remember 100+20 = 120. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(120) = 144(100)
120x = 14400
x= 120 pounds
