<u>Probability Formula</u>
We are told that the six-sided dice is fair. This means that each of the faces has the same probability of being rolled.
Therefore, the probability of rolling one is:
The probability of rolling six is:
Therefore, the probability of rolling one and then six is:
Answer:
See attachment
Step-by-step explanation:
We want to show all values of x, for
on the number line.
By the definition of absolute value function:
Divide through the first inequality by -1 and reverse the sign.
On the number line, we can represent this as shown in attachment.
in a survey of 825 farmers 125 of they were not using any type of fertilizers in their vegetable farming 150 of them were used in chemical as well as organic fertilizer the ratio of the number of any only chemical fertilizers user to the to that of only organic fertilizer is 5:6
Since there is 5280 feet in a mile, 52800/5280 is 10. Therefore the height of the jet in miles is 10 miles.
Answer:
Step-by-step explanation:
The standard deviation is the square root of the variance, and the variance is found by using the mean. So we will do that first. I will use the population variance as opposed to the sample variance since our set of numbers is small.
The mean: 8 + 12 + 15 + 17 + 18 = 70 and divide that by 5 to get
and use this to find the variance in the formula:
it is a bit difficult to enter that formula in correctly, but here's how it works mathematically:
Squaring this ensures us that we don't end up with zero, which would be useless.
so
which means that the standard deviation is
s = 3.633
(If you do it with n-1 = 4 in the denominator of the variance, you get a standard deviation of 4.062)
