To discourage guessing on the multiple-choice exam a professor assigned 4 points for a correct answer, -4 points for an incorrect answer, and -1 for leaving the question blank. what is the score for a student who had 15 correct answers, had 5 incorrect answers, and left 5 questions blank?

35

Step-by-step explanation:

4 x 15 = 60

-4 x 5 = - 20

-1 x 5 = -5

60 - 20 - 5 = 35

The Student would make a 45.

Step-by-step explanation:

So, 1st, you multiply 15x4, that would = 60. so then you would multiply 5x4, that would equal 20. So, you will subtract 20 from 60, and you will get 40. 5x1=5, so then you will add 5+40, and get 45!!

Hope this helps!!! (:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
