To find the answer, all we need to do is plug in the slope and point they gave us into the Point Slope Formula!
The point slope formula is ...
So lets put them in!
y - 4 = 2/3 (x - (-3))
Tip: remember when you subtract a negative number, it turns into adding !
So our final answer is probably D (I think you may have put a <u>typo</u>)
Answer:
Between 38 and 86 months.
Step-by-step explanation:
Chebyshev Theorem
The Chebyshev Theorem can also be applied to non-normal distribution. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by .
In this question:
Mean of 62, standard deviation of 12.
Between what two lifetimes does Chebyshev's Theorem guarantee that we will find at least approximately 75% of the computers?
Within 2 standard deviations of the mean, so:
62 - 2*12 = 38
62 + 2*12 = 86
Between 38 and 86 months.
