If we know that the length of time it takes a college student to find a parking spot in the library parking lot follows a normal distribution with a mean of 3.5 minutes and a standard deviation of 1 minute, find the probability that a randomly selected college student will take between 2 and 4.5 minutes to find a parking spot in the library parking lot, rounding to four decimal places.

0.7745

Step-by-step explanation:

Given :  The length of time it takes a college student to find a parking spot in the library parking lot follows a normal distribution with minutes and minute.

Let x represents the time to find a parking spot in the library parking lot.

Since ,

z-score corresponds x = 2 ,

z-score corresponds x = 4.5 ,

Required probability :

[using z-value table.]

Hence, the  probability that a randomly selected college student will take between 2 and 4.5 minutes to find a parking spot in the library parking lot, (rounding to four decimal place )= 0.7745

plzplzplzplz mark brainliest and have a good day

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
