According to Chebyshev's theorem, what percent of the values will fall between 100 and 124 for a data set that has a mean of 112
PIT_PIT [208]

Answer:

More than 88.889% of the values will fall between 100 and 124 for the data set that has a mean of 112 and a standard deviation of 4.

Step-by-step explanation:

The Chebyshev's theorem states that the probability of any random variable ''X'' assuming a value between a range of ''k times'' the standard deviation is at least 1-\frac{1}{k^{2}}

We can write mathematically this as :

P( μ - kσ < X < μ + kσ) \geq 1-\frac{1}{k^{2}} (I)

Where μ is the mean and σ is the standard deviation.

In this exercise :

μ = 112

σ = 4

If we replace this values in the equation (I) :

P(112-k(4)

The percent of the values falling between 100 and 124 can be written as :

P(100 (II)

This probability must be equal to P(112-k(4) (III)

Therefore if we work with (II) and (III) ⇒

(II) = (III) ⇒

P(100 ⇒

100=112-4k

124=112+4k

⇒ In any of the equations we find that

12=4k

k=3

Finally, we can write that

P(112-3(4)

P(100 ≅ 88.889%

According to Chebyshev's theorem, more than 88.889% of the values will fall between 100 and 124 for the data set.

Where is the hole for the following function located?
Nikitich [7]
It would seem to be a good idea to cancel the (x + 3) factors to get f(x) = 1/(x - 4)
This is a hyperbolic graph with a vertical asymptote at x = 4.
However when x = -3 the factor (x + 3) = 0 so cannot be cancelled at this point. 0/0 is undefined.
The graph is drawn leaving a hole in the line at x = -3
The limits as we approach x = -3 from above or below that point get closer and closer to -1/7

The correct answer is A

Answer:

  (a)  (-3/4, 1/2)

Step-by-step explanation:

There are 4 grid lines between 0 and 1 in each direction, so each grid line represents 1/4 unit. Two of them is 1/2 unit; 3 of them is 3/4 unit. The x-dimension is listed first in the ordered pair.

Point S has coordinates (-3/4, 1/2).
