use the following information to find your course average in amdm, if homework is weighted 20%, class participation is 25%, test grades are 30%, and final exam is 25%.
 homework {90, 94, 96, 90}
 class participation {95, 99}
 test grades {87, 75, 82 ,85}
final exam grade {71}
18.5 + 24.25 + 24.675 + 17.75
a. 85
b. 88.5
c. 87
d. 89

1st Question

A. 85

2nd Question  

B. 71

Step-by-step explanation:

1st Question

{90 + 94 + 96 + 90} = 370/4 = 92.5

{95 + 99}                  = 194/2 = 97

{87 + 75 + 82 + 85} = 329/4 = 82.25

{71}                =  71/1               = 71

.20(92.5) +.25(97) +.30(82.25) +.25(71) = 85.175  Rounded-up = 85

2nd Question  

.10(95) +.20(80) +.50(67) +.20(60) = 71

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
