Answer:
<em>f(50) = 109.44943 feet</em>
Step-by-step explanation:
<u>Modeling</u>
The model of a situation where the skid distance f is measured against the car speed x can be expressed as:
Using this equation, we can predict the skid distance for a car that is driving at x=50 mph by substituting in the equation of the model:
f(50) = 109.44943 feet
Answer:
Lines 3 and 4
Step-by-step explanation:
Let's examine the slope of each of the given lines to have the exact value and be able to answer the question. We use the definition of:
Line 1:
Line 2:
Line 3:
Line 4:
Line 5:
Therefore the lines that have slope strictly greater than 1 and less than 2 are:
Lines 3 and 4
Box-plot describes 5 important data of the observations. We get following values for range, median and IQR as:
A box plot has 5 data description.
IQR(inter quartile range) is the dfference between third and first quartile. (Its the horizontal length of the box)
<h3>What is the range of a data set?</h3>Range = Maximum value of the data set - Minimum value of the dataset
The missing box plot is attached below for the given problem.
From the given data, we see that, the left and right whiskers are on 80 and 100 respectively.
The left and right limit of the box are on 85 and 93 respectively.
The middle line lies on 90.
Thus, we get:
Thus, we get:
