X+ y = 44
x - y = 6
—————
2x = 50
x = 25
y = 44-x = 19
Answer:
<u>The correct answer is D. {3, 5, 8, 14, 16}</u>
Step-by-step explanation:
A is incorrect because 10 is not included in the original data set denoted by Mia.
B is also incorrect because 2 and 4 are not included in the original data set denoted by Mia.
Finally, C is also incorrect because 7 is not included in the original data set denoted by Mia.
<u>The only option that has all its values from the the original data set denoted by Mia is D.</u>
Answer:
Part 1) The graphs open downward
Part 2) The vertex is the point (-2,5)
Part 3) The axis of symmetry is x=-2
Step-by-step explanation:
step 1
we have
This is a vertical parabola open downward (because the leading coefficient is negative)
The vertex is a maximum
step 2
The quadratic equation is written in vertex form
where
(h,k) is the vertex
so
In this problem
The vertex is the point (-2,5)
step 3
The equation of the axis of symmetry of a vertical parabola is equal to the x-coordinate of the vertex
The x-coordinate of the vertex is -2
therefore
The axis of symmetry is x=-2
The entire population mean must be close to $47,600. Then the correct option is C.
<h3>What is Mean?</h3>
The mean is the simple definition of the average of a bunch of numbers. In statistics, one of the markers of central tendency is the mean.
The average is referred to as the arithmetic mean.
It's the ratio of the number of real observations to the total number of observations.
The owners of a manufacturing company conducted a survey to determine the mean income of the customers who prefer the company’s brand of clothing.
From a random sample of 100 customers, it was determined that their mean income was $47,600.
Based on statistical analysis, the entire population mean must be close to $47,600.
