Answer:
The probability is 
Step-by-step explanation:
From the question we are given that
The population mean is 
The standard deviation is 
The random number 
The sample size is 
The probability that the sample mean would be greater than 
Generally the z- score of this normal distribution is mathematically represented as

Now

substituting values


Which implies that


Now from the z-table the probability is found to be

Answer:
I figured all these out by graphing the function. See the attachment for a picture.
h(x) = (x-1)^2
It's <u>increasing over (1, ∞)</u> because the values are going up in that span.
It's <u>decreasing over (-∞, 1)</u> because the values are going down in that span.
Its range is all values of <u>y </u>
<u> 0</u> (we can see that only y-values above 0 are in the function).
g(x) = -(x+1)(x-1)
It's <u>increasing over (-∞, 0)</u> because the values are going up in that span.
It's <u>decreasing over (0, ∞)</u> because the values are going down in that span.
Its range is all values of <u>y </u>
<u> -1</u> (we can see that only y-values below 1 are in the function).
If you're asking 1.67/6 the answer is 0.276 which rounds to 0.28
Answer:
27
Step-by-step explanation:
I added 6 and 3 and got 9 for the base.
Then I multiplied 9 to 4, and got 54.
Then, I divided 54 and 2.
The Final Answer is 27.
(Hope this helps and it's not wrong...)
