Answer:
Answer:
Both centres are best described by the median.
Step-by-step explanation:
Here is a summary of the statistics from your data.
City Min Q1 IQR Q3 Max Median Mean σ
Rome 0 3.60 8.65 12.25 16 8.25 7.99 5.20
NY 1 2.25 4.69 6.64 20 5.45 6.39 5.91
The box plots below show that both centres are best described by the median.
The outlier in the New York data greatly distorts the mean but does not affect the median. The mean without the outlier would have been 4.45.
Answer:
<2=65 degrees
Step-by-step explanation:
Information provided:
Right angle=90
<25 degrees
Triangles add up to 180 degrees
90+25=115
180-115=65 degrees
Hope this helps! :)

She purchased 5 paperbacks at $4 and 3 hardbacks at $8 for a total of $44.
Step-by-step explanation:
Answer:
40/49
Step-by-step explanation:
probability that a point chosen at random in the given figure will be inside the larger circle and outside the smaller circle = ( area larger circle - area of smaller circle / area of larger circle )
area of a circle = πr² where r = radius
area of smaller circle :
radius = 6
==> plug in 6 for r
A = π(6)²
==> evaluate exponent
A = 36π
Area of larger circle :
Radius = 14
==> plug in 14 for r
A = π(14)²
==> evaluate exponent
A = 196π
We have probability = area larger circle - area of smaller circle / area of larger circle
area of larger circle = 196π
area of smaller circle = 36π
probability = (196π - 36π)/196π
==> subtract 36 from 196
probability = 160π/196π
==> simplify fraction and cancel out π
probability = 40/49
