Answer: John has an object suspended in the air. It has a mass of 50 kilograms and is 50 meters above the ground. Calculate the object's potential energy.
Step-by-step explanation:
Calculate the potential energy for a 2 kg basketball dropping from a height of 3.5 meters with a velocity of 9.8 m/sec².
cylinder but which grade is this?
Either as aforementioned above, or use
If 61 is less than 8 times the number then the number is 8.
Given 61 is 3 less than 8 times the number.
Let the number be 'x'.
The term "polynomial" in mathematics refers to a mathematical statement that consists of two or more algebraic terms that are added, subtracted, or multiplied (no division!). Constants and positive exponents are frequently used, together with at least one variable, in polynomial formulas.
we can write the equation as:
8x ₋₋ 3 = 61
arranging the like terms i.e constants.
8x = 61 ₊ 3
8x = 64
to find the value of x, divide 64 by 8.
x = 64 ÷ 8
x = 8
hence the number we get after solving the equation is 8.

A. The point estimate would be the average of the interval boundaries, which is the average of 48.2 and 56.4. This gives a point estimate of 52.3%.
b. The margin of error is the distance from either interval boundary to the point estimate. 56.4 - 52.3 = 4.1%.
c. Assuming this is solely going to be based on the class' decision, their grades should be scored on a curve. Although the margin of error is high and this seems to not have a significant distance from 50%, there is no "middle ground" in this option. We must either grade on a curve or not, and if we must choose one, we have to use to point estimate that is just slightly above 50%.
