Step-by-step explanation:
x P(x)

33 0.02 0.66 21.78
34 0.06 2.04 69.36
35 0.1 3.5 122.5
36 0.2 7.2 259.2
37 0.24 8.88 328.56
38 0.26 9.88 375.44
39 0.1 3.9 152.1
40 0.02 0.8 32
1 36.86 1360.9
We are supposed to find mean and standard deviation
Mean =
Standard deviation =
She walks 3 kilometers because 60 divided by 20 is 3
If you look closely at the graph 10 dollars are the price of 5 tickets and so we could use 2T = P as a expression and so if you plug 20 into T it would be 2(20)=P and it would become a evident 40=P as the answer (40)
Answer:
y = mx + b
y = -2x + 4
Step-by-step explanation:
m = 2 - 4 / 1 - 0 = -2 / 1 = -2
m (slope) = -2
y = mx + b (0,4)
4 = -2x + 0
<u>-0 - 0</u>
<u>4</u> = <u>-2x</u>
-2 -2
-2 = x
Equation: y = mx + b
y = -2x + 4
