Step-by-step explanation:
3 sigma= 3×0.146
= 0.438
for upper limit= sample mean + 3 sigma
for lower limit= sample mean - 3 sigma
Answer:
Step-by-step explanation:
SA = SA(prism) + SA(cylinder) – 2SA(cylinder base)
1. Surface area of rectangular prism
The formula for the surface area of a rectangular prism is
S = 2(lw + lh + wh)
Data:
l = 16 in
w = 11 in
h = 11 in
Calculations:
2(Top + Bottom) = 2lw = 2 × 16 × 11 = 352 in²
2(Front + Back) = 2lh = 2 × 16 × 11 = 352 in²
2(Left + Right) = 2wh = 2 × 11 × 11 = <u>242 in² </u>
Total area = 946 in²
2. Surface area of cylinder
A = A(top) + A (base) + A(side) = 2A(base) + A(side)
Data:
d = 8 in
h = 9 in
Calculations:
r = ½d = ½ × 8 = 4 in
3. Excluded area
Excluded area = 2A(base) = 100.48 in²
4. Total area
So,
Let's manipulate this into the y=mx + b form.
Add 4x to both sides
-6y = 4x + 24
Divide both sides by -6
Just use the slope to find the points you need.
The y-intercept is (0,-4).
The slope is
. Finding the next point:
(-6,0)
You could have also used the <em>slope intercept method.</em>
-4(0) - 6y = 24
-6y = 24
Divide both sides by -6
y = -4
(0,-4)
-4x - 6(0) = 24
-4x = 24
Divide both sides by -4
x = -6
(-6,0)
