grades in a college english class are weighted: tests 60%, book review 20%, project 20%. find the final grade of a student with averages of: tests 86, project 76, reviews 77.

57.9
91.7
65.5
82.2

82.2 (the last option)

Step-by-step explanation:

Weighted Sum

When we get a sequence of values a,b,c... and we want to know the sum of all but with different percent weights pa,pb,pc... where pa+pb+pc...=100%, we compute the weighted sum as

S=a.pa+b.pb+c.pc...

The student got this final grades: tests 86, project 76, reviews 77 and their relative weights are tests 60% (0.6), book review 20% (0.2), project 20% (0.2)

The final grade is

s=86(0.6)+76(0.2)+77(0.2)

S=82.2

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
