Step-by-step explanation:

for an ellipse, the major axis, is over the variable with the "a" component, or the greater denominator
Answer:
2, 6, 12, 20, 30
Step-by-step explanation:
To find the first 5 terms substitute n = 1, 2, 3, 4, 5 into the expression
n = 1 → 1² + 1 = 1 + 1 = 2
n = 2 → 2² + 2 = 4 + 2 = 6
n = 3 → 3² + 3 = 9 + 3 = 12
n = 4 → 4² + 4 = 16 + 4 = 20
n = 5 → 5² + 5 = 25 + 5 = 30
Answer:
C) Both sets have an interquartile range of 27.
Step-by-step explanation:
Sorted data
Set 1: 65, 66, 77, 79, 81, 93, 104, 105
Set 2: 1, 29, 56, 59, 60, 67, 72, 74
Median position: (8+1)/2 = 4.5th value
Ranges:
Set 1: 105 - 65 = 40
Set 2: 74 - 1 = 73
Medians:
Set 1: (79+81)/2 = 80
Set 2: (59+60)/2 = 59.5
IQR:
Set 1: (93+104)/2 - (66+77)/2
= 27
Set 2: (67+72)/2 - (29+56)/2
= 27
