Answer:

Distance between two ships = 73 units

Step-by-step explanation:

Note:

tangent = opposite / hypotenuse

Referring to diagram,

Distance of ship A from tower = 100 tan(90-45) = 100 units

Distance of ship B from tower = 100 tan(90-75) = 100 tan (27) = 27 units

Distance between two ships = 100-27 = 73 units

Find z if X=27, μ=20, and α=3.4. Round to the nearest hundredth if necessary.
Scrat [10]

Answer:

A. Z=2.06

Step-by-step explanation:

We want to find the Z-score of X=27 if the population mean is \mu=20,and the population standard deviation is \sigma=3.4.

We use the formula:

Z=\frac{X-\mu}{\sigma}

We substitute the values to obtain:

Z=\frac{27-20}{3.4}

Z=\frac{7}{3.4}

Z=2.06

The correct answer is A.
