If final is 25% of grade and your average was 82 before final that part is 75%. So we have (.75(82) + .25 (73)) = 80
none , 73 is a prime number and divisible only by itself
79.
To calculate the mean, add all the numbers (76 + 82 + 73 + 93 + 91 + 81 + 79 + 86 + 84 = 765) and divide by the total count (9), resulting in a mean of 85. The median, when the numbers are arranged in order (73, 76, 79, 81, 82, 84, 86, 91, 93), is 82. The mode does not exist as all numbers appear only once. The range is 93 - 73 = 20, and the standard deviation is approximately 6.07.

no it´s 72 and others
Five - in 1971, '72, '73, '82, and '84.
Since the set of data is arranged in numerical order, first we need to find the median (also called the second quartile), which separates the data into two equal groups, in our case there are 6 numbers in each group.54 65 66 68 73 75 | 75 78 82 82 87 97The first quartile (also called the lower quartile) is the middle value of numbers that are below the median, in our case is 67.54 65 66 | 68 73 75 | 75 78 82 82 87 97The third quartile (also called the upper quartile) is the middle value of numbers that are above the median, in our case is 82.54 65 66 | 68 73 75 | 75 78 82 | 82 87 97The interquartile range is the difference between the first and third quartiles, which is 15, (82 - 67).
