Answer:
3.39
Step-by-step explanation:
We will use SD formula to find our answer.

= Standard deviation.
= Mean.
N= Numbers of data-points.
We have been given that mean of our data set is 9. So we will find the square of each data point's distance to the mean.
Now let us substitute our given values in above formula.


Upon adding the square of distances we will get,

Upon dividing 46 by 4 we will get,
Upon taking square root of 11.5 we will get,
Therefore, the standard deviation for our given data set will be 3.39.
Answer:
Divide the percentage by 100 to get a decimal number. Use that number as the numerator (top) of a fraction. Put a 1 in the denominator (bottom) of the fraction. Convert the decimal to a whole number: Count how many places are to the right of the decimal.
7.5? well 7 1/2? there is the answer
Answer: False
Step-by-step explanation:
Events can be classed as being dependent or independent depending on whether the outcome of a certain event affects the outcome of another. In the scenario above, the success rate of jumps in the Northeast direction is higher than in the southwest direction and even much than in other directions. With these uneven rate of success, the probability that a fox will have a successful jump will depend on the direction in which the fox is jumping. With an high expected success probability in the Northeast and southwest than in other directions
