Answer:
a) The probability that a randomly selected college student will find a parking spot in the library parking lot in less than 3 minutes = 0.309
b) Check the beginning of Explanation for which type of dustribution this is.
Step-by-step explanation:
A distribution with the mean given and the spread around the mean (standard deviation) given, is a normal distribution. Especially as it shows that the distribution is symmetric around the mean.
To find the probability that a randomly selected college student will find a parking spot in the library parking lot in less than 3 minutes.
We first standardize '3 minutes'.
The standardized score is the value minus the mean then divided by the standard deviation.
z = (x - μ)/σ = (3 - 3.5)/1 = - 0.5
probability that a randomly selected college student will find a parking spot in the library parking lot in less than 3 minutes.
P(x < 3) = P(z < -0.5)
We'll use data from the normal probability table for these probabilities
P(x < 3) = P(z < -0.5) = 1 - P(z ≥ - 0.5) = 1 - P(z ≤ 0.5) = 1 - 0.691 = 0.309.
The points of intersection for the two functions and round to the nearest tenth exists (0.5, 1.4) and (4.85, -0.3).
<h3 /><h3>How to solve the system of equations?</h3>
Given:
f(x) = -0.5x+2
g(x) = x³ - 5x² + 3
The point of intersection exists the point where f(x) = g(x)
x³ - 5x² + 3 = - 0.5x + 2
x³ - 5x² + 3 + 0.5x - 2 = 0
x³ - 5x² + 0.5x + 1 = 0
Factorize and estimate the value of x
Let x = 0.53 and 4.85
substitute the value of x = 0.53
f(0.53) = -0.5(0.53) + 2
f(0.53) = -0.265 + 2
f(0.53) = 1.375
If x = 4.85
f(4.85) = -0.5(4.85) + 2
f(4.85) = -2.425 + 2
f(4.85) = -0.245
Therefore, the points of intersection for the two functions and round to the nearest tenth exists (0.5, 1.4) and (4.85, -0.3).

Answer: Choice C; f(0) = 6
The reason why this is true is because x = 0 leads to y = 6. Recall that f(x) is the output of the function while x is the input. Because y = f(x), we can say that the point (x,y) = (0,6) means f(0) = 6.
