Answer:
Mean of the data set is one of the most commonly used measures of central tendency. Basically, it means the average value of the data set. For finding it, one doesn't have to arrange the data in order. All it takes is to add them all together and divide that by the number of the data. It can be mathematically written as:
(x1 + x2 + x3 + ..... + xn) / n
This obviously means that Ashrita did the best job in calculating the mean of this data set.
2/7 x 14q+3 1/2 negative 3q=9
Answer 57q-3
Answer:
6.347 g Zinc to the nearest thousandth.
Step-by-step explanation:
Using the molar atomic mass of the elements:
65.38 g Zinc produces 65.38 + 2(16 + 1.008) = 99.396 g Zn(OH)2
So by proportion amount of zinc required to produce 9,65 g Zn(OH)2
= (65.38/99.396) * 9.65 g Zinc
= 0.65777 * 9.65
= 6.347g Zinc.
The steps below are presented in order to arrive to the value of k of the given equation.
First, multiply both sides of the equation by the variable k since the left-hand side of the equation has it in the denominator. This will be,
(k + 12/ k)(k) = 8(k)
Then, we simplify,
k + 12 = 8k
We then, subtract 8k to both sides of the equation,
k - 8k + 12 = 8k - 8k
Simplifying,
-7k + 12 = 0
Then, subtract 12 from both sides of the equation and divide both sides by -7. This will us the final answer of,
k = 12/7
