Answer:
For a data set of N elements:
{x₁, x₂, ..., xₙ}
The mean is:
The mean absolute deviation is:
And the population standard deviation is:
In this case, our set has 5 elements, and the set is:
{2, 4, 6, 9, 14}
The mean of this set is:
The mean absolute deviation is:
And the population standard deviation is:
First, find the difference between the original price and the reduced price;
65 - 45 = $20 difference
Then, divide the difference by the original amount;
20/65 ≈ 0.3077
Then, multiply this by 100 to convert the decimal into a percentage;
0.3077 * 100 = 30.77%
The percent of change would be about 30.77%
Answer:
Step-by-step explanation:
An equation in the vertex form is written as
Where the point (h, k) is the vertex of the equation.
For an equation in the form the x coordinate of the vertex is defined as
In this case we have the equation .
Where
Then the x coordinate of the vertex is:
The y coordinate of the vertex is replacing the value of in the function
Then the vertex is:
Therefore The encuacion excrita in the form of vertice is:
To find the coefficient a we substitute a point that belongs to the function
The point (0, -1) belongs to the function. Thus.
<em>Then the written function in the form of vertice is</em>
Answer:
Noah mixes 4 scoops of powder with 6 cups of water.
Means Noah ratio will be or 0.67
Andre mixes 5 scoops of powder with 8 cups of water
Means Andre ratio will be or 0.62
As, or 0.66 > 0.62
We can say that content of orange powder will be more in Noah mixture than in Andre's Mixture.
Hence, Noah's mixture will taste more like orange, than Andre's mixture.
Step-by-step explanation:
