256,64,16,4 is decreasing exponential function
for other option they simply follow an AP
2,6,10,14,18
common difference d=4
Ответ:
a) 83
b) mean and mode are both 83
Step-by-step explanation:
a) mean is the average. so add all the numbers and divide by the number of numbers.
88 + 73 + 81 + 83 + 79 + 94 + T = 83
7
b) median - put the numbers in numerical order, smallest to largest, what is the middle number (4th number) 73, 79, 81, 83, 83, 88, 94
mode - which number shows up most frequently?
