Answer: 48

Step-by-step explanation:

a student must have an average on five test that is greater than it equal to 80% but less than 90% to receive a final grade of B

Bad White [126]

Answer:

89–100

Step-by-step explanation:

Let x represent the grade on the fifth test. The average for 5 tests wants to be between 80 and 90, so we have ...

80 ≤ (78 +62 +91 +80 +x)/5 ≤ 90

Multiplying by 5 gives

400 ≤ 311 +x ≤ 450

Subtracting 311 gives the range for the fifth test grade.

89 ≤ x ≤ 139

Since the maximum available score is 100, the range on the 5th test for an overall B grade is ...

89 ≤ x ≤ 100 . . . . where x is the grade on the 5th test

malfutka [58]

Answer:

$3+2(log_{2}(x+1) )$

Step-by-step explanation:

First simplify the quadratic present $8(x^{2}+2x+1)=8(x+1)^{2}$

$log_{2}8+log_{2}(x+1)^{2}$

⇒ $3+2(log_{2}(x+1) )$
