Answer:
A: Exponential
B: Quadratic
C: Linear
Step-by-step explanation:
Solution:-
- We will closely inspect each Table and find the difference between each "Y" value at every unit increase in "x" value:
Table A:
X Y ΔY/ΔX
1 5 xxxxxx Exponential because [ ΔY/ΔX ]
2 11 11 - 5 = 6 increases at the fastest rate out of all
3 29 29 - 11 = 18 functions.
4 83 83 - 29 = 54
5 245 254 - 83 = 171
6 731 731 - 254 = 477
Table B:
X Y ΔY/ΔX Δ^2Y/ΔX^2
0 5 xxxxxx xxx Quadratic because
1 7 7 - 5 = 2 xxx Δ^2Y/ΔX^2 is a constant
2 13 13 - 7 = 6 6-2 = 4 for all quadratic functions
3 23 23 - 13 = 10 10-6 = 4
4 37 37 - 23 = 14 14-10 = 4
5 55 55 - 37 = 18 18-14 = 4
Table C:
X Y ΔY/ΔX
3 20 xxxxxx Linear because
6 18 2 / 3 ΔY/ΔX is a constant
9 16 2 / 3 for all linear functions
15 12 2 / 3
27 4 8/12 = 2/3
39 -4 8/12 = 2/3
Answer:1, 2, 3, 5, 6, 10, 15, 30.
Step-by-step explanation:
The national interest rate on houses for 25 years is 4.3%. The banker wishes to test that the local interest rates are lower than the national rate. So he should use the initial data of 4.3% interest as his base data. Then he should investigate the rates of houses in the local vicinities and compare it to his base data.
Answer:
C
Step-by-step explanation:
(x, y) -> (1/2x, 1/2y)
When you dilate a side, point, etc, you are multiplying the original dimension by the scale factor. That is represented in option C: the original x and y are multiplied by the scale factor, 1/2! Hope that helps! :)
Answer:
D
Step-by-step explanation:
First find the probability using the normal distirbution formula X - mean / standard deviation for both X = 350 and X =450 to get the values -1 and 1 so thi(-1) < P(Z) < thi(1) if you are familiar with normal distirbution table values you will calculate that the overall probability is 0.6827
knowing this we can roughly expect how much emergencies are in the response times by 0.6827 x 144 = 98
