Answer:
0.14
Step-by-step explanation:
Here, we want to find the probability that a student earns the grade of A
Mathematically, we have this as the frequency of A divided by the sum of all frequencies
From the question, the sum of all frequencies will be (5 + 10 + 15+ 3 +2) = 35
Now we place the frequency of A over this
This gives;
5/35 = 1/7 = 0.14
Solving:
![x - 3(2-x) = 4x - (x - 1)](https://tex.z-dn.net/?f=x%20-%203%282-x%29%20%3D%204x%20-%20%28x%20-%201%29)
Delete the first parentheses by the distributive property, with the distributive property, we multiply the '3' first, then resolve it and the second parentheses eliminate by changing the sign:
![x - 6 + 3x = 4x - x + 1](https://tex.z-dn.net/?f=x%20-%206%20%2B%203x%20%3D%204x%20-%20x%20%2B%201)
<span>Now, put the numbers with letter (incognito) to the right and numbers without letter to the left, changing the signal when changing sides.

![x + 3x - 4x + x = 6 + 1](https://tex.z-dn.net/?f=x%20%2B%203x%20-%204x%20%2B%20x%20%3D%206%20%2B%201)
