Answer:

Step-by-step explanation:

When in doubt, have your calculator evaluate this.

___

The reference angle for 5π/3 is π/3. The angle is in the 4th quadrant, where the secant is positive.

sec(5π/3) = sec(π/3) = 1/cos(π/3) = 1/(1/2)

sec(5π/3) = 2

What is the circumference of the circle? Round your answer to the nearest foot

Nat2105 [25]

It would be 78.5 because if you do the work for example here is work i did for a question on my quiz

Where "C" is circumference and "d" is diameter.

Substituting your values in, we have:

Which, when rounded, is 37.7.
thats my work but when you do your work for your question you get 78.58 and you would round to the nearset tenth and you get 78.5

Hope this helps:) please mark branliest would really apperciate it thx

A teacher dropped 8 coins on the table and counted the number of tails to simulate the number of questions a student might guess

Tomtit [17]

Answer:

Get 0 tails (correct answers in the test)

Get 5 tails (correct answers in the test)

Step-by-step explanation:

This is a problem of empirical probability calculation, since the teacher tries to find by means of the experimental method, the number of correct answers that a student could correctly guess in a true / false test with 8 questions.

If the teacher throws the 8 coins and then counts the number of tails, the graph shows the frequency with which 1, 2, 3, 4, 5, 6, 7 and 8 tails are obtained in the 100 attempts.

Therefore, the least probable result was the one that was obtained less frequently in the experiment or, in other words, the one that contains fewer points in the diagram, which in this case are:

Get 0 tails (correct answers in the test)

Get 5 tails (correct answers in the test)
