Answer:

y= 8x+1 (0,1) y=6x+3 (0,1)

= 8×0+1 =6×0+3

y = 1 =3

Step-by-step explanation:

= 8×1+1 (1,9) =6×1+3 (1,9)

y=9 =9

=8×4+1 (4,14) =6×4+3 (4,14)

y=33 =27

=8×2+1(2,4) =6×2+1 (2,4)

Graph 1: 2/9, 2: 1/2 3: 1/5

Step-by-step explanation:

To find slope you do y2-y1/x2-x1 (rise over run). For graph 1, y2=2, y1=0. x2=9,x1=0. 2-0=2, 9-0=0, so the overall slope is 2/9

Suppose the variable x is represented by a standard normal distribution. What is the probability of x > 0.3 ? Please specify
uysha [10]

Answer: 0.38

Step-by-step explanation:

Since the variable x is represented by a standard normal distribution, the probability of x > 0.3 will be calculated thus:

P(x > 0.3)

Then, we will use a standard normal table

P(z > 0.3)

= 1 - p(z < 0.3)

= 1 - 0.62

= 0.38

Therefore, p(x > 0.3) = 0.38

The probability of x > 0.3 is 0.38.
