Answer:
Step-by-step explanation:
Given is a list of prices in dollars for one night at different hotels in a certain region
To find range, variance and std deviation.
Mean 155.75
Standard Error 23.80782434
Median 150
Mode #N/A
Standard Deviation 67.33869616
Sample Variance 4534.5
Kurtosis -1.593759971
Skewness 0.344624422
Range 172
Minimum 86
Maximum 258
Sum 1246
Count 8
Thus we find range = 172 $. This gives an idea about the lowest and highest difference.
Variance = Average of squares of deviations from the mean= 4533.329 $^2gives us an idea about the dispersion of data. This helps to have an idea about the price rise or low in different hotels
Std deviation is square root of variance 67.33 $ shows an idea about the dispersion and also coefficient of variation as a ratio of mean to std deviation.
To solve this, take a look at the images provided and first find out the number of polygons out of the total number of cards given which would be 3 polygons out of 5 cards, which would be better represented as the fraction 3/5. Now, the question asks to find the probability of Julie picking a card that shows a polygon, and since 3 out of 5 of the cards are polygons, your answer would be 3/5.

Since 340 % van be written to 3.4, just use 88.8 to divide it by 3.4, so the answer should be 26.1176470588, if ur question needs you to round up to a number of decimals, do it
