Answer:
-6.205
Step-by-step explanation:
The first table that starts with -1,2 is exponential
The second table that starts with -2,-7 is linear
The last table is quadratic
Using the given points, I was able to graph the functions t(x) and p(x) as shown in the picture. The difference between a quadratic function and an exponential is the degree of the equation. The quadratic equation has a degree of 2 while that of an exponential function is a degree raised to a variable. For better illustration, I would provide examples:
Quadratic equation: y = 2x²+5
Exponential equation: y = 2³ˣ
If you would test it quantitatively the rate of change, or the slope, between points is greater for exponential than quadratic equations. Because a slight increase in x, will cause an exponential rise, To you observe visually if the slope is greater if the curve is closer to a vertical line. From the picture, we can see that the blue curve has a greater slope.
Therefore, the exponential function is t(x).
Bill is better bowler than George.
To decide who's the relative better bowler, George or Bill, I've first drawn bell curves for each of their leagues. George's league is in red mean is 150 a standard deviation of 20. And Bill's League Demean is higher at 160, but the standard deviations it is lower at 15, so I've numbered my bell curve by 15.
Now to decide who's relative better bowler, I'm going to calculate their Zscores for George, His observed value is 180, which would fall right here on our number line, and his Z score is gonna be 180- the mean. So he's 30 points above the mean, Divided by the standard deviation (180-150)/20=1.5 And then for bill, we're going to do the same thing. His score is also, let's see here his score is 190,(190-160)/15=2And you can probably see just by marking that on the bell curve, that that's actually two standard deviations above the ME, which is more than George is 1.5 standard deviations above the mean. So we can say that Bill is better bowler.
