Answer:
3rd option
Step-by-step explanation:
x < 7
means that x cannot equal 7 but all values less than 7
since not equal at either end of interval use parenthesis, not brackets , then
(- ∞ , 7 ) ← is the required interval
The class is weighted as follows:
60% Regular Tests
10% Final Exam
15% Project
15% Homework
The total weighted points possible for the class are as follows:
(100+100+100+100+100)*.6 + 100*.1 + 100*.15 + 100*.15 = 340
To calculate her individual final weighted grade we plug in her scores for each category and complete the following computation:
(92+83+77+84+82)*.6 + 88*.1 + 95*.15 + 77*.15 = 285.4
So her weighted grade percent would be 285.4/340 = 83.9% which is a B.
A number that is no more than 20 is less than
After x years the population of a town is 3460*[(1.35)^x]
Answer:
x>14
Step-by-step explanation:
Step 1: Simplify both sides of the inequality.
-4>-2x+24
Step 2: Flip the equation.
-2x+24<-4
Step 3: Subtract 24 from both sides.
-2x+24-24<-4-24
-2x<-28
Step 4: Divide both sides by -2.
-2x-2<-28-2
x>14
If it is right can I have brainliest.
