Answer:
3, 4, and 5
Step-by-step explanation:
Given: We're looking for x, x+1, and x+2
Requirements: (x+1)+(x+2)=3(x)
Solve equation:
x+1+x+2=3x
2x+3=3x
3=x
This means the three consecutive integers are 3, 3+1, and 3+2 which is the same as 3, 4, and 5
Variance = square of standard deviation
Variance = (2.5)^2 = 6.25 = 6.3 to the nearest tenth.
Answer:
b. y = 4x + 3
Step-by-step explanation:
slope intercept form is y = mx + b
where m equals the coefficient before x and b is the y intercept
so, your answer has to be y = m(aka 4)x + b(aka 3)
or,
y = 4x + 3
