The mean represents the typical value in a set of data for what type of distribution?
choose the correct answer below.
a.
for distributions that are bimodal
b.
for distributions that are skewed
c.
for all distributions
d.
for distributions that are roughly symmetric

For skewed distributions, the mean will be too small or too large depending on which tail is pulled out. This is why choice A is not the answer.

Choice B is not the answer because bimodal distributions will have the mean between the two modes, assuming the data is roughly symmetrical on either side. Though the majority of the data values is in the peaks, so its likely better to go with the mode in this case.

Choice C is wrong because A is not correct.

Choice D is the answer because the majority of the data values is either at or close to the peak point where the median and mode will also be close to as well. All three values are identical if the distribution is perfectly symmetric (eg: normal distribution).

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
