Solution :
Given data :
20.1 33.5 21.7 58.4 23.2 110.8 30.9
24.0 74.8 60.0
n = 10
Range : Arranging from lowest to highest.
20.1, 21.7, 23.2, 24.0, 30.9, 33.5, 58.4, 60.0, 74.8, 110.8
Range = low highest value - lowest value
= 110.8 - 20.1
= 90.7
Mean = 
Sample standard deviation :
S = 29.8644
Variance = 
= 891.8823
Examples of How to Find Unit Rate or Unit Price
Ryan purchased 3 apples for $1.80. What is the unit price, or the cost of one apple?
<span>We want to know the price per apple unit so we set up a ratio with the number of apples in the denominator. The total price goes in the numerator. So the fraction is 1.80/3.Complete the division: 1.80 ÷ 3 = .60. You can conclude that the per apple price unit rate is $0.60/1. Ryan paid a unit price of $0.60 per apple (60 cents per 1 apple = .60/1).</span>
The pottery store can make 176 coffee mugs in an 8 hour day. How many mugs can they make in one hour?
<span>We want to know the number of mugs made per hour unit so we set up a ratio with hours in the denominator. The total number of mugs made per day goes in the numerator. So the fraction is 176/8.Complete the division: 176 ÷ 8 = 22. You can conclude that the per hour mug-making unit rate is 22/1. The pottery store makes 22 mugs per hour (22 mugs per 1 hour = 22/1).</span>
Kylie can run 12 laps in 30 minutes. How many laps does she run per minute?
<span>We want to know the laps per minute unit so we set up a ratio with minutes in the denominator. The total laps goes in the numerator. So the fraction is 12/30.<span>Complete the division: 12 ÷ 30 = 0.4. You can conclude that the per minute lap unit rate is 0.4/1. Kylie can run 0.4 laps per minute (0.4 laps per 1 minute = 0.4/1).</span></span>
Answer: the distance would be 75 mi
Answer:
Statements A and D
Step-by-step explanation:
A. Since all of the values surrounding x = 0.5 reflect across that point, there is a line of symmetry at x = 0.5
B. This is not a y intercept since in the point (-12,0) the x value is not zero and at y intercepts, it should be zero.
C. Same thing from statement B, the y value for the x intercepys should be zero, not 4 or -3.
D. To help visualize this, take the slope of the secant line from x = -4 to x = 0.
(8 - (-10))/(-4 - 0) = 18/(-4) or -9/2. Since the slop is negative, the function is decreasing on this interval.
