This question is incomplete as it was not properly stated. The complete question reads: Marcus and Jeremy both simplified the expression −(5²) + 3. Marcus claimed the answer is −22, while Jeremy said it was 28. Who is correct? Please explain the reasoning behind the errors in the other student's calculation. The answer is that Marcus is correct; the outcome is indeed -22. Detailed explanation: The expression to evaluate is -(5²) + 3, leading to: -(25) + 3 resulting in -22. This calculation is accurate. Marcus correctly considered the parentheses in his expression which is important. Jeremy incorrectly squared -5 without acknowledging it was within a parenthesis. Thus, in Jeremy's incorrect calculation, he computed -(5²) + 3 as 25 + 3 = 28, making his answer erroneous as he overlooked the significance of the parenthesis.

zzz [12365]

Answer: The other two observations are 97 and 107.

Explanation:

We know that

Mean = 100

Mode = 98

Range = 10

And from the formula,

Range = Highest - Lowest.

Let’s set the highest observation as x and the lowest as y.

Thus, we have the equation x - y = 10 (equation 1).

The observations can be represented as:

x, 98, 98, y.

Using the mean formula yields:

Mean = \frac{\text{Sum of observation}}{\text{N.of observaton}}.

This means our second equation is:

x + y = 204.

By applying the elimination method to solve these linear equations, we find:

x = 97.

and

x+y=204\\y=204-x\\y=204-97\\y=107.

Therefore, the other two observations are 97 and 107.
