A student earned grades of 84, 78, 84, and 72 out of 100 on her four regular tests. She scored 78% on the final exam and 86% on

Anna71 [15]

Her weighted mean grade is 81.2% if the student earned grades of 84, 78, 84, and 72 out of 100 on her four regular tests.

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We have a student who earned grades of 84, 78, 84, and 72 out of 100 on her four regular tests. She scored 78% on the final exam and 86% on her class projects.

The weighted mean can be calculated as:

$\rm = 0.4\times\dfrac{[(84+78+84+72)]}{4} + 0.3\times 78 + 0.1\times 86+ 0.2\times 87$

After calculating, we get:

= 81.2%

Thus, her weighted mean grade is 81.2% if the student earned grades of 84, 78, 84, and 72 out of 100 on her four regular tests.

Ned has a coupon for one fourth off the cost of any item. Today all items are on sale for one third off. Does it matter whether

Aleksandr [31]

Answer:

Step-by-step explanation:

Let the cost of the item is C.

Case I :

first sale is applied

so, the price of item = one third = C - C/3 = 2C/3

Now coupon is applied

so, the price of item = $\frac{2C}{3}-\frac{1}{4}\times \frac{2C}{3}$ = C/2

case II :

First coupon is applied

so, the price of item = C - C/4 = 3C/4

Now sale is applied

the price of item = $\frac{3C}{4}-\frac{1}{3}\times \frac{3C}{4}$ = C/2

So, it does not matter that either coupon is applied first or the sale is applied first the final cost of the item remains same.
