Answer:

(a) symmetric

(b) The mean, median, and mode may be the same value.

and, The mode is the tallest bar in a histogram.

Step-by-step explanation:

Data is said to be symmetric if it is not skewed. i.e. if it has peaked at the center of the distribution.

Skewness gives us an idea about the shape of the curve.

Kurtosis enables us to have an idea about the flatness and peakedness of the frequency.

Mode represents the highest repetition of the observation.

The mean, median, and mode can have the same value.

The histogram represents the frequency of observation by the length of the bar this is the same as Mode. Thus, the mode is the tallest bar in a histogram.

Variance is the square of standard deviation and it is defined as, the sum of the square of the distance of an observation from the mean.

So, Variance is the correct option.

A fitness club charges $25 per month as well as a one-time $80 fee of all new members which equation represents the cost in doll

madam [21]

Answer: So if you want to find the total cost (c) for a certain number of months (m) and it costs $35 per month, you just need to multiply the number of months by the cost per month. So

35m=c

If you want to see the units cancel

($35/month)(months)=$

The months will cancel out, and you will be left with total dollars.

Not sure about the second part of your question, but if you wanted to figure out how much it would cost to be a member for 6 months, you would just plug in 6 for m.

35(6)=c

c=210

So $210

Hotels, like airline, often overbook, counting on the fact that some people with reservations will cancel at the last minute. A

agasfer [191]

Answer: The required probability is 0.334.

Step-by-step explanation:

Since we have given that

N = 15 reservations

probability of reservations will not be used = 0.2

probability of reservations will be used = 1-0.2=0.8

Let X be the Binomial variable,that the number of reservations canceled.

We need to find the probability that more than 8 but less than 12 reservations.

So, it becomes,

$P(8$

Hence, the required probability is 0.334.
