The number of patients treated at Dr. McCormick’s dentist office each day was recorded for nine days. These are the data: 13, 16
NARA [144]
First, lets sort the list from smallest to greatest. This will help with median, mode, and range.

4, 6, 10, 12, 12, 13, 16, 16, 16

Next, lets find the mean. Mean is found by adding all numbers up, then dividing them by the number of entries in the data set.

4+6+10+12+12+13+16+16+16 = 105
105 / 9 = 11.7

So the mean is 11.7.

Next, we'll find the median. The median is the value in the center of the list. Because there are 9 values, that means the center of the list is 5 with four numbers on each side of it. The 5th number in the list is 12, so that's our median.

Continuing, the mode is the number or numbers that appears the most often. For this data set, 16 appears 3 times while all other numbers appear 2 times or less. So, the mode is 16.

Lastly, the range is the difference between the largest number and the smallest number.

16 - 4 = 12

So the range is 12.

The second answer in the list matches all of these values, and is the correct solution.

The line passes through the point (2,-9) and has a zero slope. Write the answer in slope-intercept form.
Shtirlitz [24]

Answer:

Okay so for finding the equation of a line, which is a function, the equation is set to y, so you can eliminate A and B. When the slope of an equation is 0, we are saying that the y value of any point of the line is going to be the same, which is 9 from the given point (2,9).

So the answer is C. y=9

The ratio of the measures of the three angle in a triangle is 15:8:13. Find the measure of the three angles.
Angelina_Jolie [31]

Answer:

a=15x; b=8x; c=13x

180°=a+b+c=15x+8x+13x=36x

=> x=180÷36=5

=> a=15×5=75°; b=8×5=40°; c=13×5=65°
