Answer:
Seth's solution is not correct. The x-coordinates are correct, but the y-coordinates are not. The graphs intersect at (-2, -7) and (3, 13).
Step-by-step explanation:
By equating the expressions for y and solving the resulting quadratic, Seth correctly found the x-coordinates of the points of intersection. He needs to compute the corresponding y-coordinates using one or the other of the original equations.
For x=-2,
y = 4·(-2) +1 = -7
For x=3,
y = 4·3 +1 = 13
The points of intersection are (-2, -7) and (3, 13).

Converting Normal distribution to standard normal because A normal distribution is determined by two parameters the mean and the variance. A normal distribution with a mean of 0 and a standard deviation of 1 is called a standard normal distribution. Hence it's easy to work with standard normal distribution.
P(0.14<<0.47) = P((0.41-0.44)/0.01830) <
<(0.47-0.44)/0.01830
Using normal algebra we get:
= P(-1.64 < z < 1.64)
= P(z < 1.64) - P(z < -1.64)
= 0.9495 - 0.0505
= 0.8990
Thus, required probability is 0.8990
