Answer:
15.866%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 3,282 gallons of kerosene
μ is the population mean = 3,087 gallons of kerosene
σ is the population standard deviation = 195 gallons
For x > 3282 gallons
z = 3282 - 3087/195
z = 1
Probability value from Z-Table:
P(x<3282) = 0.84134
P(x>3282) = 1 - P(x<3282) = 0.15866
Converting to percentage
0.15866 × 100 = 15.866%
The percent of flights on these particular routes that will burn more than 3,282 gallons of kerosene is 15.866%

The volume of a Cone =

Since for the ice cream cone has h = 4 inches; r = 0.75; π = 3.14
Then Volume of the Cone = 2.355 in³
∴ This ice cream cone can hold ≈
2.36 in³ of ice cream without overflowing
Answer:
y = 4x + 40
Step-by-step explanation:
y - 0 = 4 (x + 10)
y -0 = 4x + 40
y = 4x + 40
The equation of a circle with center at (h,k) and radius r is

we are given
center is at (3,2)

solving for y



take the derivitive to find the slope at any point

we can use point slope form
for apoint (h,k) and slope m, the equation is
y-k=m(x-h)
not sure if you want in terms of what
I'll just say for a point (h,k)
so we get

where

that's the equation of the tangent line at (h,k) for arbitrary values of r
