The final exam of a particular class makes up 40% of the final grade, and Moe is failing the class with an average (arithmetic m

amm1812

Answer:

%82.5

Step-by-step explanation:

The final exam of a particular class makes up 40% of the final grade
Moe is failing the class with an average (arithmetic mean) of 45% just before taking the final exam.

From point 1 we know that Moe´s grade just before taking the final exam represents 60% of the final grade. Then, using the information in the point 2 we can compute Moe´s final grade as follows:

$FG=0.40*FE+0.60*0.45$ ,

where FG is Moe´s Final Grade and FE is Moe´s final exam grade. Then,

$\frac{ FG-0.60*0.45}{0.40}=FE$ .

So, in order to receive the passing grade average of 60% for the class Moe needs to obtain in his exam:

$FE=\frac{ 0.60-0.60*0.45}{0.40}=0.825$

That is, he need al least %82.5 to obtain a passing grade.

If (-1, y) lies on the graph of y=2^2x then y=

zubka84 [21]

Answer:

y is 1/4 when x is -1 if I did interpret your equation right. Please see that I did.

I believe the equation to be $y=2^{2x}$ . If you meant $y=2^2x$ , please let me know.

Thanks kindly.

Step-by-step explanation:

If (-1,y) lies on the graph of $y=2^{2x}$ , then by substitution we have:

$y=2^{2\cdot -1}$ .

We just need to simplify to determine y:

$y=2^{2 \cdot -1}$

Multiply the 2 and -1:

$y=2^{-2}$

Use reciprocal rule for exponents to get rid of the negative:

$y=\frac{1}{2^2}$

$2^2$ just means $2(2)$ :

$y=\frac{1}{2(2)}$

$y=\frac{1}{4}$ .
