Answer:
find the difference of points on the graph
Step-by-step explanation:
The cumulative frequency graph (CDF) represents the integral of the probability distribution function (PDF). You find the probability that X is in some interval by subtracting the value of the CDF at the low end of the interval from the CDF value at the high end of the interval.
p(a < x < b) = cdf(b) -cdf(a)
Answer:
18
Step-by-step explanation:
10% of 30 = 3
50% of 30 = 15
10%+50%=60%
3+15=18
Found a complete text of the above question:
<span>After giving a statistics exam, professor Dang determined the following five number summary for her class results: 57 65 75 88 97
Use this information to draw a box plot of the exam scores. Choose the correct graph below.
57 and 97 serves as the whiskers of the box plot. 57 is the minimum number while 97 is the maximum number.
65 and 88 serves as the ends of the box while 75 is the line found inside the box.
Choices of for the correct graph is attached but my answer is graph B.</span>
We know that
The sum of the lengths of any two sides of a triangle is greater than the length of the third side (Triangle Inequality Theorem)
Let
A------> Lincoln, NE
B------> Boulder, CO
C------> third city
we know that
in the triangle ABC
AB=500 miles
BC=200 miles
AC=x
Applying the Triangle Inequality Theorem
1) 500+200 > x------> 700 > x------> x < 700 miles
2) 200+x > 500----> x > 500-200------> x > 300 miles
the solution for x is
300 < x < 700
the interval is------> (300,700)
the possible distances, d, in miles, between Lincoln, NE, and the third city, are in the range between 300 and 700 miles
