Answer:
20 mins
Step-by-step explanation:
13.50 - 1.50 = 12
12 / 0.60 = 20
Answer:
C. The volume of the cylinder is about 25 cubic inches greater than the volume of the cone.
Step-by-step explanation:
The volume of a cone =
and the volume of a cylinder = πr²h
(cone vol = 201.06 in³ and cylinder vol=226.19in³)
The confidence interval in the form p+E is p ± E = 0.7725 ±0.435
<h3>How to rewrite the
confidence interval?</h3>
The confidence interval is given as:
0.555< p < 0.99
To rewrite the above expression in the form p+E, we use the following equations
p = (0.99 + 0.555)/2 = 0.7725
E = (0.99 - 0.555) = 0.435
So, we have:
p ± E = 0.7725 ±0.435
Hence, the confidence interval in the form p+E is p ± E = 0.7725 ±0.435

Answer:
y = - 2x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y =
x - 9 ← is in slope- intercept form
with slope m = ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 2, thus
y = - 2x + c ← is the partial equation
To find c substitute (3, 2) into the partial equation
2 = - 6 + c ⇒ c = 2 + 6 = 8
y = - 2x + 8 ← equation of perpendicular line
