Jamal's score is 80
<u>Explanation:</u>
Given:
Number of questions = 100
Let w be the number of wrong answers
Let r be the number of right answers
According to question,
r = 4w
r + w = 100
Solving both the equations we get:
4w + w = 100
5w = 100
w = 20
If w = 20 then r = 4 X 20 = 80
Therefore, Jamal's score is 80
The answere to your question is $31 because 2 times 8 is 16 and 3 times 5 is 15 so if 15 plus 15 is 30 but sense it is 16 instead of 15 it is $31.
You can count from 6-10 and you would get c) 5/10
The formula y = mx + b sometimes appears with
different symbols.
For example, instead of x, we could use the
letter C. Instead of y, we could use the letter F.
Then the equation becomes
F = mC + b.
All temperature scales are related by linear
equations. For example, the temperature in
degrees Fahrenheit is a linear function of degrees Celsius.
Water freezes at: 0°C, 32°F
Water Boils at: 100°C, 212°F

Answer:
Data in this table are written in decimal numbers. That means that they don't present the number of students voting for their favorite sport, but portion of student from that grade. Another way to write decimal numbers is in percentages. For example 30% of students is 0.30, 48% is 0.48 etc.
Now that we know this, looking at the table we can see that the correct answer is C.
