Aprofessor at a local community college noted that the grades of his students were normally distributed with a mean of 74 and standard deviation of 10. the professor has informed us that 6.3 percent of his students received a's while only 2.5 percent of his students failed the course and received f's.
a. what is the minimum score needed to make an a?
b. what is the maximum score among those who received an f?
c. if there were 5 students who did not pass the course, how many students took the course?

i need the options

step-by-step explanation:

answer: 30

step-by-step explanation: its 30 because im a basketball player and stephen curry hits most of his shots so if you put 30 you might make the shot goodluck

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33

your answer is b.

x = 33.9

y = 65.6
