C. Which is (0,-2).
Plugging in C into the first equation:
y<(x^2) + 2 = (0^2) + 2 = 2 which is greater than -2
[2 > -2]
Then the second eqaution:
y>(x^2) - 6 = (0^2) - 6 = 0 - 6 = -6 which is less than -2
[-6 < -2]
6x - 2y = 18
-2y = -6x + 18
y = -6x/-2 - 18/2
y = 3x - 9
comparing to y = mx + c,
m = 3,
Slope = 3
Answer:
30 values ; greater than or equal to 10 and less Than or equal to 39
Step-by-step explanation:
Counting the number of leaves in the plot, we have 30 leaf values. This gives the number of dataset.
The minimum value is the number created by the combination of the least stem value and the lowest leaf value, which is 10
The maximum value is obtained from the combination of the highest stem and leaf value. The highest value is 39
The 90th percentile is 1.2816 standard deviations from the mean. That tells you the standard deviation is ...
... (40 in - 38 in)/(1.2816) ≈ 1.56 in
The standard deviation for height for 4-year olds seems to be 1.56 inches.
