The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%
How to find the probability?
We know that roughly 75% of the students take the bus, then, if we select a student at random.
There is a probability of 0.75 that the student takes the bus.There is a probability of 0.25 that the student does not take the bus.The probability that at most 8 out of 9 students take the bus, is equal to one minus the probability of the 9 taking the bus, which is:
p = (0.75)^9 = 0.075
Then we have:
P = 1 - 0.075 = 0.925
The probability that at most 8 of them take the bus to school is 0.925, written in percentage form this is 92.5%

Which has a greater value 3/10 or 13/20
13/20 is bigger
To compare these two fractions, we make them both have a common denominator. I will be using 20 as the common denominator.
3/10 * 2
= 6/20
6/20 < 13/20
13/20 is bigger.
The inequality equation is 13/20 > 3/10
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the first fraction be p
Now , the value of p = 3/10
Let the second fraction be q
Now , the value of q = 13/20
On simplifying the equations , we get
p = 0.3
q = 0.65
And , q > p
So , the the value of 13/20 is greater than 3/10
Hence , the inequality is 13/20 > 3/10

Step-by-step explanation:
Given;Dan has saved $80 so far to buy a skateboard.This is 40% of the price of the skateboard.To Find;The total amount of skateboard.Now, Let the full price be y we get,
y × 40/100 = 80
y × 2/5 = 80
2y/5 = 80
2y/5 × 5 = 80 × 5
2y = 400
2y/2 = 400/2
y = 200
Thus, The full price of skateboard is $200.

Find the solution of the system of equations.
X – 10y = 18
- 6x – 10y = 32
Answer: x = 46, y = 2.8
Step-by-step explanation:
equation 1: x - 10y = 18
equation 2: -6x - 10y = 32
The first equation can be re-written as: x = 18 + 10y
This can be substituted into the second equation and solved:
-6(18+10y) - 10y = 32
-108 + 60y - 10y = 32
50y = 140
.: y = 2.8
Using this value of y we can find x:
x = 18 + 10y
x = 18 + 10(2.8)
x = 18 + 28
x = 46
So, our solutions are: x = 46, y = 2.8
