Answer:
0.3935 to 4 places of decimals.
Step-by-step explanation:
Use binomial probability tables or an online probability calculator.
Here Prob(a singles success) = 0.08333 ( that is 1/12)
Number of successes = 3 and number of trials = 27.
You want the probability of the variable X being >= x.
Answer:
Step-by-step explanation:
You can use the identity
The sign is negative because the angle is in the 3rd quadrant.
This corresponds to ...
a. -(4√17)/17
5
6x5 is 30
I’m pretty sure that’s the answer hope it helps
For the first question, the answer is A. You take 90 and multiply it by 3, then you get the time that it takes for one worker to mow the large park.
For the second question, you take 50 = k/0.25. To find k, you would want to multiply both sides with 0.25 to cancel the 0.25 on k's side. 50 times 0.25 is 12.5. I think C is your answer although I'm not really confident.
