Answer:
C) 26
Step-by-step explanation:
41 , 35,30 , X , Y ,15
Number of data's = 6. So, median will be the average of . 3 and 4th term
Median =
30 + X = 25*2
30 + X = 50
X = 50 - 30
X = 20
Mode is 15
So, Y = 15
41,35,30,20,15,15
Y as function of x
y=f(x)
that just means y=-2x+3
that is form y=mx+b
m=slope
b=y intercept
so then
y=-2x+3
the y intercept is 3 so go up 3 units on the y axis from the center (0,0) and put a point there
the slope is -2
so slope is rise/run
rise/run=-2=-2/1
so go down 1 units and go right 1 unit
put another point there
we get the opints (0,3) and (1,1)
connect them
see graph below
The formula for area of a cone is A=πr(r+√h²+r²). The radius is half the diameter, so 22.5.
Plug our numbers into the formula.
A=π22.5(22.5+√96²+22.5²)
the answer is 8560.16
Radius = √(7-(-1))² + (8-(-7))² = √8²+15² = √289 = 17
Let the point be (-15,y)
(-15-(-7))² + (y-(-1))² = 17²
⇒ -8² + (y+1)² = 17²
⇒ 64 + (y+1)² = 289
⇒ (y+1)² = 289 - 64 = 225
⇒ y+1 = +15 or -15
⇒ y = +15-1 or -15-1
⇒ y = 14 or -16
T<span>h</span>us, the point can be either (-15,14) or (-15,-16)
