To find the mean of a dot plot, add up all of the data and divide by how many numbers there are.

In this case, the data added up is 4 + (5 x 4) + (6 x 3) + (7 x 2) + 10

4 + (5 x 4) + (6 x 3) + (7 x 2) + 10 = 66

With this information, we can now find the mean.
66/11=6

Therefore, the mean is 6. Hope this helps! Feel free to ask any questions.

Zigmanuir [339]

Answer:

The distance from the base of the statue to the ship is 771.60 ft

Step-by-step explanation:

Refer the attached figure

Height of statue AB= 250 feet

The tourist sees a ship coming into the harbor and measures the angle of depression as 18°.

So, ∠ACB = 18°

We are supposed to find the distance from the base of the statue to the ship i.e. BC

In ΔABC

$Tan \theta = \frac{Perpendicular}{Base}$

$Tan 18^{\circ}=\frac{AB}{BC}$

$Tan 18^{\circ}=\frac{250}{BC}$

$BC=\frac{250}{Tan 18^{\circ}}$

$BC=\frac{250}{0.324}$

BC=771.60 ft

Hence the distance from the base of the statue to the ship is 771.60 ft
