Peter needs to find the distance across the pond shown in the diagram. He starts from point C and walks 200 meters to point B. T
gladu [14]

Answer:

c=231.87 m

Step-by-step explanation:

When we read this example we can see that Peter will form triangle with those sides :

a=200 m,

b=180 m

cos X=cos (180-105)=cos75

x is angle.

Now, we can use this rule :

c^{2} =a^2+b^2-2abcosX

Now, let's evaluate :

c^{2} =200^{2} +180^{2} -200*180cos75\\c^2=40000+32 400-18 645\\c^2=53765\\c=231.87 m

Based on past experience, it is estimated that a restaurant will serve 122 guests on a weekday evening. This is an example of wh
Vitek1552 [10]

Answer: Experimental probability.

Step-by-step explanation:

This starts as "based on past experience."

So we can suppose that this estimation is obtained by looking at the mean of the number of guests on the past N weekday evenings. (With N a large number, as larger is N, more data points we have, and a better estimation can be made)

Then, this would be an experimental probability, because it is obtained by repeating an experiment (counting the number of guests on weekday evenings) and using that information to make an estimation.
