Answer:
x > -2/3
Step-by-step explanation:
, subtract 1/3 from both sides
, multiply both sides by 2
The sample standard deviation is 15.3.
Given data items,
84, 85, 83, 63, 61, 100, 98,
Number of data items, N = 7,
Let x represents the data item,
Mean of the data points,
Hence, sample standard deviation would be,
a+b equeals 90
Smaller number = 10 (y)
Larger number = 16 (x)
Step-by-step explanation
Check:
x+y=26
2y-4=x
16+10=26
2(10)-4=16
20-4=16
16=16
