Answer:
Step-by-step explanation:
V=f(d, t) (measured in kilograms per square kilometer)
Time, t is measured in hours
Distance, d is measures in Kilometers
We want to determine the unit of
Since
The data is larger for intermediate values of x, so the parabola opens downward. That leaves only the 2nd and 4th choices, where the x² coefficient is negative.
To determine which of those is appropriate, it is only necessary to consider x=1. The 2nd choice will give a y-value near 100; the 4th choice will give a y-value near 250.
The fourth choice is appropriate:
... y = -9.16x² +73.04x +183.3
_____
Alternatively, you can consider that for the x-coordinate of the vertex to be positive (it's about +4), the coefficients of the x² and x terms must have opposite signs. Using this consideration, you don't even need to evaluate the expression to determine that the 4th choice is the correct one.
Answer:
minimum 56
Median (Q2) 65
Lower Quartile (Q1) 60
Upper Quattile (Q3) 67
Maximum 75
Step-by-step explanation:
If you notice, there are 5 distinguished points of data, and I used all the points for each thing you asked for. You just have to recognize the minimum and maximum are the largest and smallest of all the data, and there is clearly nothing outside of the range of 56-75. then Q1, Q2, and Q3 are on the box itself. The median, just like with numbers, will always be the middle line. It is not directly in the center because there are more people in the 65-75 value range than the 56-65 value range.
