Answer:
(-1, 7)
Step-by-step explanation:
We'll use the midpoint formula: ([x₁ + x₂]/2, [y₁ + y₂]/2)
x₁ = -4
x₂ = 2
y₁ = 6
y₂ = 8
Our equation will look like this
([-4 + 2]/2, [6 + 8]/2)
( -2/2, 14/2 )
(-1, 7)
36 ft, just subtract 18 from 54
Answer:
Step-by-step explanation:
Radius r = 15
Circumference = 2πr = 30π cm
Circumference of cone = arc length of sector
= 30π × 216°/360°
= 18π cm
Radius of base of cone = 18π/(2π) = 9 cm
Slant height of cone = radius of circle = 15 cm
Height of cone = √(15² - 9²) = 12 cm
Answer:
The correct option is A.
Step-by-step explanation:
The difference between actual value and predicted value is called residual.
Formula of residual is
![e=y-\hat{y}](https://tex.z-dn.net/?f=e%3Dy-%5Chat%7By%7D)
Where, y is observed value or actual value and
is predicted value.
![e=3-1.6](https://tex.z-dn.net/?f=e%3D3-1.6)
![e=1.4](https://tex.z-dn.net/?f=e%3D1.4)
The value of residual is 1.4 and option A is correct.
