Eight students were asked how many miles they live from school. Their answers are listed below.5, 4, 6, 1, 1, 1, 1, 4Find the mo
Tatiana [17]
Answers:
mode = 1
range = 5

-----------------------------------------

Explanation:

The mode is 1 because it is the most frequent value. It shows up four times compared to the other values (5,6) which only show up once and the value 4 only shows up twice.

The range is 5 because we subtract the max and min values to get 5.
In other words,
Range = Max - Min
Range = 6 - 1
Range = 5

a cereal box can hold 144 cubic inches of cereal. if the box is 8 inches long and 1.5 inches wide how tall is the box?
Andreas93 [3]
The volume of a rectangular prism is simply length * width * height.
Therefore, all we have to do to find the height of the cereal box is divide the volume by the width and the length.

144 / 8 = 18

18 / 1.5 = 12

The cereal box is 12 inches tall.
Hope that helped =)

A buoy oscillates in simple harmonic motion y= A cos cos as waves move past it. The buoy moves a total of 3.5 feet (vertically)
NNADVOKAT [17]

Answer:

a) y = 1.75 ft cos (\frac{\pi}{5}t)

b) v(t) = -1.0995 sin (\frac{\pi}{5}t)

Step-by-step explanation:

Part a

Since the buoy oscillates in simple harmonic motion the equation to model this is given by:

y = A cos (wt +\theta)

For this case from the info given we know that:

2A = 3.5 , A = \frac{3.5}{2}= 1.75 ft

"It returns to its high point every 10 seconds." That means period =10 T =10s, and the angular frequency can be founded like this:

w = \frac{2\pi}{10}= \frac{\pi}{5}

Assuming that the value for the phase is \theta =0 our model equation is given by:

y = 1.75 ft cos (\frac{\pi}{5}t)

Part b

From definition we can obtain the velocity with the derivate of the position function and if w calculate the derivate we got this:

\frac{dy}{dt}= v(t) = -1.75 ft (\frac{\pi}{5}) sin (\frac{\pi}{5}t)

v(t) = -1.0995 sin (\frac{\pi}{5}t)
