Answer:
0.9812
Step-by-step explanation:
Given that human weights are normally distributed with mean 175 and standard deviation 36 pounds
For a sample of 9 people std error of sample would be
Thus we find that sample mean is N(175, 12)
The plane will lift safely if sample average <200 pounds
i.e. Probability that it can safely lift off (i.e., the average weight of a person in the helicopter is less than 200)
=
~0.981
Firstly you forgot to attach the mathematical work along with your question. I am answering the question based on my research and knowledge and hope that it helps you. "The simplification performed in step 2 is invalid or incorrect" is the statement that <span>best applies to the sample mathematical work. The correct option among all the options given in the question is option "B".</span>
Answer:
The correct option is (4).
Step-by-step explanation:
The complete question is:
Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(275)?
- Houses sell on the market for an average of $275,000 and stay on the market an average of 275 days before being sold.
- Houses sell for an average of $275,000.
- f(275) indicates houses stay on the market an average of 275 days before being sold.
- f(275) represents the average number of days houses stay on the market before being sold for $275,000.
Solution:
The function f (p) is defined as the average number of days a house stays on the market before being sold for price <em>p</em> in $1,000s.
The function provided is: f (275)
That is, <em>p</em> = $275,000.
So, the function (275) describes the average number of days a house stays on the market before being sold for price $275,000.
Thus, the correct option is (4).
Volume = length times width times height
Volume = 40 mm times 25 mm times 2mm
Volume = 2000 cubic mm (If you want to write it in a different unit, 2 cubic meters)
One cubic mm = 0.0005 ounces
2000 cubic mm = weight of one cubic mm times 2000
2000 cubic mm = 0.0005 times 2000
2000 cubic mm weighs 1 ounce
To find the coordinates for Z, we first need to find Z.
Z is at the top right of the first quadrant/Quadrant 1 (top right square). To find the coordinates, look for the lines that intersect on Z.
For the X-Axis (Horizontal line, side to side),it is at 9. This means the first half of our coordinates is (9,y), so we can eliminate the second and last answer choices.
For the Y-Axis (Vertical line, straight up and down), Z it located on the 10th line, so the second coordinate for Z is 10.
Our coordinates are (9,10).
Your correct answer is A.), as we are in Quadrant 1.
I hope this helps!
