25=
[{50 divided by 5} plus 3]times 2 -1=25
The answer is 7*5*3*4=420
A sample of size <em>n</em> taken from a normally distributed population with mean <em>µ</em> and standard deviation <em>σ</em> has a sample mean of <em>µ</em> and standard deviation of <em>σ</em>/√<em>n</em>.
So the sample mean would still be 180.1, while the sample standard deviation would be 100/√94 ≈ 10.31.
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
Answer:
Position of the submarine now relative to the water surface
Step-by-step explanation:
It says that the position of a submarine relative to the water surface was -32 1/4 feet . A downward navigational maneuver increased it's depth by 15 1/2 feet.
Now we need to find about what is the position of the submarine now relative to the water surface.
Downward navigation means we 15 1/2 is negative
so we will just add both values to get the final answer:
Position of the submarine now relative to the water surface =
