Answer:
A company produces electric insulators. The strength of the insulators is important since a broken insulator may cause a short circuit. Unfortunately, the strength varies significantly due to the material. Because of the expense, only a limited number of insulators could be tested. The engineers sampled 25 insulators (From a production run of 200), and conducted a destructive test to determine the force that was required to break the insulators. The mean value of this force was 1723 lbf with a sample standard deviation of 90 lbf. You may approximate the population standard deviation with the sample standard deviation for the following questions. a. Determine if the population is large enough or if a finite population correction (FPC) factor is needed. If so, what is the FPC factor? b. For 95% confidence, determine the margin of error (+ lbf) c. For these conditions, estimate the range of the probable population mean. Provide lower and upper values. For 95% confidence, determine the margin of error ( Assume the same mean and sample standard deviation. What is one advantage and one disadvantage of using 50 insulators instead of 25 insulators? d. lbf) if 50 insulators were tested.
Step-by-step explanation:
Answer:
3x - 14 < 3x - 15
-14 < -15
never true
Step-by-step explanation:
Step-by-step explanation:
1st term = -n²+6
= -(1)²+6
= -1+6
=5
2nd term = -(2)²+6
= -4+6 = 2
3rd term= -(3)²+6
=-9+6 = -3
4th term= -(4)²+6
= -16+6 = -10
5th term = -(5)²+6 = -25+6 = -19
6th term = -(6)²+6 = -36+6 = -30
5,2, -3,-10,-19, -30
optionB
Pairs which is Adjacent side for quadrilateral MOLE is given below.
Step-by-step explanation:
Given:
Quadrilateral MOLE
Pair of adjacent sides of the quadrilateral.
Adjacent sides have one vertex common.
Option A: MO and LE
These sides does not have common vertex.
MO and LE are opposite sides in the quadrilateral MOLE.
It is not true.
Option B: EO and ME
In the quadrilateral, ME is not a side.
So it is not true.
Option C: LE and OL
In the quadrilateral, OL is not a side.
So it is not true.
Option D: ML and LE
These sides have common vertex L.
Therefore ML and LE are pair of adjacent sides.
It it true.
Hence ML and LE is a pair of adjacent side for quadrilateral MOLE.
