Answer:
13.35 millimeter. (About)
Step-by-step explanation:
To find the area or circumference of any circle, you need to use pi. So, if we are trying to fine the area of a <em>semicircle, </em>you use the the formula:
πr²/2
So, if the radius is 8.5,
8.5 · 3.14 = 26.69
Now we divide it by 2.
26.69 = 13.345
Since the question is asking to round to the hundredths, the answer will be 13.35 millimeters.
Answer:
b. 0.80
Step-by-step explanation:
The probability distribution means that we have these following probabilities:
0.05 probability of having a loss of $100.
0.15 probability of having neither a loss nor a profit.
0.30 probability of a profit of $200.
0.40 probability of a profit of $300.
0.10 probability of a profit of $400.
On a given day, the probability the bakery will have a profit of $200 or more is
Either 200, 300 or 400.
Looking at it's probabilities;
0.3 + 0.4 + 0.1 = 0.8
So the correct answer is:
b. 0.80
