If the pitch was higher you would have to draw the dots waiver. You get it?
Like this:
Answer: The mean of the samples is 32.325.
Proportion of the defective unit is =
Explanation:
The point estimate of the mean of the sample:
First calculate the mean of the 40 samples:
The mean of the samples is 32.325.
Defected pieces in the samples whose life span is less than the 26 days = 2
Proportion of the defective unit is =
Answer:
The right option is option E. None of the answer choices given are totally correct.
Explanation:
All insulators normally have an equal amount of positive and negative charges distributed on their surface.
The amber rod (an insulator) is called negative because after the coming together with fur (another insulator), the amber rod rubs off electrons from the fur onto itself and has an overall more negatively charged particles than positively charged particles on its surface.
The fur in turn becomes positive because it has more positive charges than negative on its surface.
So, the convention allows the now rubbed off amber rod to be called negative.
So, it is evident that none of the answer choices are totally correct, the right answer is more of a mix of some of the answer choices and more!
Hope this helps!!
The gravitational force of attraction on an object placed at the surface of the earth is known a weight of the object. The weight of the object is different on different planets because it depends on the gravitational constant.
The weight is defined by the Newton's second law as the product between the mass and the gravitational acceleration, that is
W = mg
And its unit in SI is Newton (N) and Lbf in American Unit.
Therefore the option D is the only correct here. 1600 kilo Newton or 1600kN.
