The correct statement about the slopes they both calculated is: D. Both calculated the slope as 9 over 2.
Slope = rise/run = change in y / change in x
Slope of line AC calculated by Olivia by Liam = (9-0)/(2-0)
= 9/2
Slope of line AC calculated by Olivia = (27-9)/(6-2)
= =18/4
= 9/2
The true statement about the slopes calculated would be: D. Both calculated the slope as 9 over 2.

Answer:
22.93
Step-by-step explanation:
We have to evaluate the expression:
i.e. it could also be written as:
i.e. we need to evaluate:
Hence, this could be written as:
Now, the series inside the parenthesis is a geometric series with first term as 1 and common ration as 0.3.
Hence, we could apply the summation of finite geometric series and get the answer.
We know that the sum of geometric series with n terms and common ratio less than 1 is calculated as:
Here a=1 and r=0.3
Hence the sum of geometric series is:
Hence, the final evaluation is:
Hence,
Answer: Option A: 500.
Step-by-step explanation:
If 95% of the students are present in a school, then the number of absent students is 5% of the total number of students. We are given that the number of absent students is 25, so we can set up an equation:
0.05x = 25
Solving for x, we get:
x = 25 / 0.05 = 500
Therefore, the total number of students in the school is 500.
Therefore, the correct answer is Option A: 500.
