Answer:
At least 75% of the observations lie between 16 and 28.
Step-by-step explanation:
The Chebyshev’s Theorem says:
For any numerical data set, at least
of the data lie within k standard deviations of the mean, that is, in the interval with endpoints
for populations, where k is any positive whole number that is greater than 1.
Given:
![\mu=22\\\sigma=3](https://tex.z-dn.net/?f=%5Cmu%3D22%5C%5C%5Csigma%3D3)
The interval (16, 28) is the one that is formed by adding and subtracting two standard deviations from the mean.
![(\mu - k\sigma,\mu +k\sigma)\\(22 - 2\cdot3,22 + 2\cdot3)\\(16,28)](https://tex.z-dn.net/?f=%28%5Cmu%20-%20k%5Csigma%2C%5Cmu%20%2Bk%5Csigma%29%5C%5C%2822%20-%202%5Ccdot3%2C22%20%2B%202%5Ccdot3%29%5C%5C%2816%2C28%29)
For k = 2, we see that
, which is 75% of the data must always be within two standard deviations of the mean.
At least 75% of the observations lie between 16 and 28.
Answer:
the answer is No because with 90% accuracy and 0.9 probability some emails will be spam and will not be categorized as spam since it is using probability.
The Accuracy percentage is correct at 90%
Step-by-step explanation:
probability is the likelihood of an event to occur or not
Hello there!
Factors of 15: 1, 3, 5, 15
Factors of 25, 1, 5, 25
5*5*3=75
The least common factor of 15 and 25 is 75 is the right answer.
Hope this helps!

Answer:
Square pyramid
Step-by-step explanation:
A square pyramid is a solid consisting of a square, a point not in the same plane as the square, and all points between them.
It can't be these
Triangle means the plane of the figure that is formed by connecting 3 particular points but it is not in a straight line. (B)(B) ← incorrectincorrect
Cube means the solid figure of having 6 square plane faces which that the angle between about 2 adjacent sides that is a right angle (C)(C) ← incorrectincorrect
Square Prism means the shape of a square that has approximately 3 dimensional shape that has a rectangular sides and shape, but it has about 2 that are square(D)(D) ← incorrectincorrect
Your answer is ↓
square pyramid (A)(A) ← CORRECT!CORRECT!
Good luck on your assignment and enjoy your day!
