Question 58
Tsunamis, or large waves created by
underwater landslides or undersea
earthquakes. The speed of the tsunami
in meters per second is s = 3.1√d,
where d is the depth of the ocean in
meters. Find the depth of the water is
240 meters per second.
Answer
Level 14
Answer 58
s = 3.1√d
s = 10 m
240= 3.1√d
(240)2 = (3.1√d)2
57,600 = 9.61d
57,600/9.61 = d
5994 = d

First: Determine the
upper quartile and
lower quartile values.
LQ = 2.1 and
UQ = 6.5
Second: Determine the
interquartile range.
IQR = UQ – LQ =
6.5 – 2.1 = 4.4 and then multiply
by 1.5  4.4 x 1.5 = 6.6
Third: Add 6.6 to the UQ and
subtract the 6.6 from the LQ to
establish the outlier limits.
IQR + UQ = 6.6 + 6.5 = 13.1
LQ – IQR = 2.1 – 6.6 = -4.5
Fourth: Compare.
There is one outlier,
16.6, because it is
greater than 13.1.

Question 66
Solve the equation.
4(2x + 7) - 6 = 3x
Answer
Level 12
Answer 66
4(2x + 7) - 6 = 3x
8x + 28 – 6 = 3x
8x + 22 = 3x
8x – 3x + 22 – 22 = 3x – 3x – 22
5x = -22
5x/5 = -22/5
x = -22/5

Question 68
Sports broadcasts often include sound
collection from the field of play. The
temperature affects the speed of sound near
Earth’s surface. The speed V when the
surface temperature t degrees can be found
using the equation
V = 20√(t + 273)
The speed of sound at Earth’s surface is
often given as 340 meters per second. On
what temperature is this speed based?
Answer
Level 14
Answer 68
V = 20√(t + 273)
340 = 20 √(t + 273)
(340)2 = (20 √(t + 273))2
115,600 = 400(t + 273)
115,600 = 400t + 109,200
6400 = 400t
6400/400 = t
16 oC = t
