In a recent year, the total scores for a certain standardized test were normally distributed, with a mean of 500 and a standard deviation of 10.2. Answer parts (a)–(d) below
(a) Find the probability that a randomly selected medical student who took the test had a total score that was less than 489.
The probability that a randomly selected medical student who took the test had a total score that was less than 489 is
(Round to four decimal places as needed)

none.

step-by-step explanation:

b=-1

find the slope and y-intercept of the second equation.

m2=0

b

=

−

6

b=-6

compare the slopes

m

m of the two equations.

m

=

5

,

m

2

=

0

m1=5,m2=0

compare the two slopes in the decimal form. if the slopes are equal, then the lines are parallel. if the slopes are not equal, then the lines are not parallel.

m1=5,m2=0

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type

step-by-step explanation:

add them
