Consider the speed in miles per hour that Officer Williams clocked the last seven drivers at with his radar. Find the interquartile range of the speeds.

This question is incomplete because it did not indicate that speed in miles per hour that Officer Williams clocked the last seven drivers at with his radar.

Complete Question

Consider the speed in miles per hour that Officer Williams clocked the last seven drivers at with his radar. Find the interquartile range of the speeds.

Speeds of the drivers in miles per hour is given as:

a) 58 miles/hour

b) 72 miles/hour

c) 55 miles/hour

d) 65 miles/hour

e) 70 miles/hour

f) 81 miles/hour

g) 66 miles/hour

66 miles per hour

Step-by-step explanation:

Inter quartile range can be defined as the measurement in statistics that indicates the middle of a set of given data when you separate that data into two equal quartiles, one quartile on the left and one quartile on the right leaving a specific figure or number in the center.

It is important to note that the given set of data must be rearranged in ascending order or rank from the least to the greatest before finding the inter quartile range.

The speed of the last seven drivers on Officer Williams radar was given as:

a) 58 miles/hour

b) 72 miles/hour

c) 55 miles/hour

d) 65 miles/hour

e) 70 miles/hour

f) 81 miles/hour

g) 66 miles/hour

This speeds would be re arranged properly as :

55, 58, 65, 66, 70, 72, 81

The inter quartile range of these speeds is the number in the middle and that is 66 miles per hour.

true statements:

a) x + y = y + x   ⇒ commutative property of addition

b) (x * y) * z = x * (y * z) ⇒ associative property of multiplication

d) (x + y) + z = x + (y + z) ⇒ associative property of addition

false statements:

c) x - y = y - x   should be: x - y = - y + x

e) (x - y) - z = x - (y - z) should be: (x - y) - z = x - (y + z)

step-by-step explanation:

687.09 dollars       happy now

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09
