Answer:

p value =0.024

Step-by-step explanation:

Given that a sample of 46 copper wires had a mean resistance of 1.03 mΩ with a standard deviation of 0.1 mΩ

Let μ represent the mean resistance of copper wires of this type.

H_0: \mu \leq 1\\H_a: \mu >1

(one tailed test )

Sample size n = 46

\bar x = 1.03\\s = 0.1\\Std error = \frac{0.1}{\sqrt{46} } \\=0.0147

Mean difference = 0.03

Test statistic t = mean difference /std error

=2.035

df = 45

p value for one tailed=0.023884

Find the volume of a cylinder with a diameter of 10 inches and height of 20in
weqwewe [10]

Answer:

V = 500 pi in^3

or approximately 1570 in ^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h  where r is  the radius and h is the height

The diameter is 10. so the radius is d/2 = 10/2 =5

V = pi (5)^2 * 20

V = pi *25*20

V = 500 pi in^3

We can approximate pi by 3.14

V = 3.14 * 500

V = 1570 in ^3

Consider the volume of the region shown below, which shows a right circular cone with top radius 3 cm and height 10 cm. We have
koban [17]
I have the same problem here with a slight change in the given values:

radius is 2 & height of 6 indicates the bounding line is y = 3 x---> x = y / 3.... 

<span>thus the [ π radius ² thickness ] yields π (y² / 9 ) <span>dy ,</span> y in [ 0 , 6 ] for the volume... </span>

a Riemann sum is then : y_i = 0 + i [ 6 / n ] = 6 i / n , i = 1,2,3...n and do a right side sum 

<span>π Σ { i = 1,2,3..n } [ 36 i² / 9 n² ] [ 6 / n ]
</span>
I hope my guide has come to your help. God bless and have a nice day ahead!

Explain why all linear angle pairs must be supplementary, but all supplementary angles do not have to be linear pairs?
dimulka [17.4K]
Two angles are supplementary if their measures sum 180°.

Linear angle pairs are adjacent angles (they are together) and they form a straight angle, which is 180°. Therefore, they are supplementary.

But two angles may be separated and yet add 180°, then they are supplementary but are not linear angle pairs.
