Answer:
5
Step-by-step explanation:
The distance between any two points (x₁, y₁) and (x₂, y₂) is given by the distance formula:
(x₁, y₁) = (1, 4) and (x₂, y₂) = (4, 0)
So distance is
The answer to that problem is (3, 1)
Answer:
158 cases
Step-by-step explanation:
Given tbe quadratic regression model :
y = -2x^2 + 40x + 8
y = number of cases of a new disease
x = number of years
The predicted number of cases of a new disease in 15 years can be calculated thus ;
Put x = 15 in the equation ;
y = -2(15)^2 + 40(15) + 8
y = - 2 * 225 + 600 + 8
y = - 450 + 600 + 8
y = 158
158 cases
Answer:
