Answer:
7 students.
Step-by-step explanation:
To pass science, a student requires at least 70 grades so students who scored below 70 will be failed.
From the given bar chart we can calculate the number of students who scored below 70 grades
Students who earned 50 - 59 = 2
Students who earned 60 - 69 = 5
Therefore, number of students who failed were
2 + 5 = 7 students.
Answer:
Step-by-step explanation:
Let's let B represent the amount of blue cubes, Y represent the amount of yellow cubes, and G represent the amount of green cubes.
We know that there are three times as many blue cubes as yellow cubes. In other words:
We also know that the are as five times as many green cubes as blue cubes. So:
If Sarah takes a random cube, the chance it will be a yellow cube will be the total amount of yellow cubes over the total amount of cubes. In other words:
We can simplify this. Let's substitute 5B for G. This yields:
Combine like terms:
We can then substitute 3Y for B. This gives us:
Multiply:
Again, add:
We can now cancel out the Y:
So, the chance of Sarah picking out a yellow cube is 1/19 or about 5.3% chance.
And we're done!
