Probability of drawing a face card or 4 is 16/52=4/13
Answer:
By the Chebyshev Theorem, 75% probability of a randomly selected state having between 21 and 53 multi-million dollars
Step-by-step explanation:
We have no information about the distribution, so we use the Chebyshev's theorem to solve this question.
Chebyshev Theorem:
75% of the data within 2 standard deviations of the mean.
89% of the data within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 37
Standard deviation = 8
What is the probability of a randomly selected state having between 21 and 53 multi-million dollars
21 = 37 - 2*8
So 21 is 2 standard deviations below the mean.
53 = 37 + 2*8
So 52 is 2 standard deviations above the mean.
By the Chebyshev Theorem, 75% probability of a randomly selected state having between 21 and 53 multi-million dollars
The height (h) of the water in cm for d days is given by the equation h(d) = -0.9d + 1200
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let h represent the height of the swimming pool after d days, the water evaporates 0.9 cm in height each day. If the pool water starts at 1200 cm hence:
h(d) = -0.9d + 1200
The height (h) of the water in cm for d days is given by the equation h(d) = -0.9d + 1200
