Answer:
(a)Range = 96
(b)Variance=1059.36
(c)Standard Deviation =32.55
Step-by-step explanation:
(a)Range
- Highest Value = 97
- Lowest Value = 1
Range = Highest Value - Lowest Value
=97-1
=96
(b)Variance
The variance of a sample for ungrouped data is defined by the formula:
First, we determine the mean of the sample data.
=10593.64
Therefore:
Variance, Variance,
(c)Standard Deviation
The results tell us that there is great variability in the number of jerseys of the player as evidenced by the high standard deviation and range.
Answer:
5
Step-by-step explanation:
Natalie
100 + 10x
Her sister
25 + 25x
Where
x = number of months
Equate Natalie and her sisters equation
100 + 10x < 25 + 25x
100 - 25 < 25x - 10x
75 < 15x
Divide both sides by 15
x < 75 / 15
x < 5
Your equation would be y = 5x + 40 because you already made 0 and are selling 5 each day
So some points you may use are (0, 40), (1, 45), (5, 65), (10, 90)
