Answer:
Step-by-step explanation:
5,9,11,(13,16),16,19,21
the mean(middle number) = (13 + 16) / 2 = 29/2 = 14.5
Q1 = (9 + 11) / 2 = 20/2 = 10
Q3 = (16 + 19) / 2 = 35/2 = 17.5
interquartile range (IQR) = Q3 - Q1 = 17.5 - 10 = 7.5 <==
78×.33=25.74 busses are new
25.74+15=40.74 new busses
78+15=93 total busses
40.74/78=0.5223076923= 52% will be new with the new 15 busses
Answer:
d) (3, 4), (5, 5), (5, 2)
Step-by-step explanation:
<em></em>
<em>We are asked to determine which orderpair in the option has the range of {2,4,5}</em>
Using the definition of range:
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
So in the given options if we write the relation in the form of (x,y) then 4, 5, 2 are the values in the range
15.8 I believe. Since 20 isn’t a option 15 is the closest. Good luck I have good faith I have you the right answer
