Answer:

x = -0.5

Step-by-step explanation:

I have marked on the graph the values of ƒ(x) that correspond to the different x-values.

At x = -2.5, ƒ(x) is decreasing, concave up, and > 0.  

At x = -1.5, ƒ(x) is decreasing, concave down, and < 0.  

At x = -0.5, ƒ(x) is increasing, concave up, and < 0.  

At x = 0.5, ƒ(x) is increasing, concave up, and > 0.  

At x = 2.5, ƒ(x) is decreasing, concave up, and > 0.  

The only point for which ƒ(x) is simultaneously increasing, concave up, and less than zero is x = -0.5.

X=-.5, it’s less than 0, and concave up & increasing in this situation are the same.

Studentka2010 [4]

Answer:

The median of the lower half of the data was determined to be 67 while the median of the upper half of the data was determined to be 92.

Step-by-step explanation:

<u>Step 1:  Order from least to greatest</u>

51, 56, 62, 72, 79, 81, 82, 85, 89, 95, 97, 98

<u>Step 2:  Determine the median of the lower half of the data</u>

There are 12 numbers which means that there is going to be 6 numbers on both sides of the data.  So using the first 6 numbers we will be able to determine the median of the lower half of the data.

51, 56, 62, 72, 79, 81

Since there is an even amount of numbers, that means that we will need to find the middle between the 3rd and 4th number.  We can do that by adding them up together and dividing by 2.

(62 + 72) / 2 = 67

Step 3:  <u>Determine the median of the upper half of the data</u>

So using the first 6 numbers we will be able to determine the median of the upper half of the data.

82, 85, 89, 95, 97, 98

Since there is an even amount of numbers, that means that we will need to find the middle between the 3rd and 4th number.  We can do that by adding them up together and dividing by 2.

(89 + 95) / 2 = 92

Answer: The median of the lower half of the data was determined to be 67 while the median of the upper half of the data was determined to be 92.
