2/3 = 11/x
(11)2/3 = 11/x(11)
11/3 = x
x = <span>3.66666666667
So your answer is ....
x = 3.7
Good luck! :))

Answer:
0.216
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
The probability that an event will happen added to the probability that the event will not happen gives 1. In other words, the outcome of a probability cannot exceed 1.
The probability that an event a will happen or that another independent event b will happen is the sum of the probability that a will happen to the probability that b will happen.
The probability that the event B will occur 3 times in a row may be interpreted as BBB and in probability, "and" is interpreted as multiplication while "or" is addition.
Pr(BBB)
= 0.6 * 0.6 * 0.6
= 0.216

Answer:
Considering each Y level the line lowers by 1 unit, the answer would be <em><u>-1</u></em>.
Answer:
<u>Mean:</u> 810.51
<u>Standard deviation:</u> 128.32
Step-by-step explanation:
First, we calculate the sample mean. We have 35 data samples, so we compute it as
.
In general, given a set of <em>n </em>samples
, we calculate the sample mean as
.
For the standard deviation
, we first begin by calculating it's square. It can be obtained from the formula

By taking square root after computing the right hand side, we attain the desired value.
The attached image shows the dot diagram of this sample. The bottom pink vertical line shows the mean, and the two horizontal pink lines have a lenght of
.
The standard deviation means "The average expected distance a new sample will be from the mean". That's why usually, data samples which are denser around the mean have smaller standard deviations (as opposed to distributions who have a lot of values far away from the mean, which will make the standard deviation grow bigger).
