<u>Part 1</u>
Using the distance formula,
So, the measure of the longest side is 6 units.
<u>Part 2</u>
Triangle ABD will have vertices A(1,7), B(-2, 2), and D(1,2).
We already know that
Using the distance formula,
So, ABD is a scalene triangle.
<u>Part 3</u>
From part 2, we know that the length of side AD is 5 units.
Answer:
0.8188 or 82%
0.0000643
Step-by-step explanation:
Given that engineering specifications on the shelf depth of a certain slug to be turned on a CNC lathe are from .0275 in. to .0278 in.
If x is the dimension then X is N(0.0276, 0.0001)
Or is Normal (0,1)
a) Fraction of shelf depths are in specifications
=
b) For 98% to be within the specifications,
Margin of error =
For 98% critical value Z two tailed is 2.33
Hence std error =
So sigma should be = 0.0000643
