Answer:
--- You
--- Another student
Reason: Because there is a variation in the given dimensions
Step-by-step explanation:
Given
Your measurement

Another students'

Solving (a): The area
Area is calculated as:

For you


For the other student


Solving (b): Reason for the variation in the areas
The given measurements are estimates of the dimensions of the rectangle.
Since there is a variation in the estimates, there will be some level of variation in the calculated area.
Answer:
Step-by-step explanation:
We group the number 5:
5(x² + 3x + 2.25)
Now inside the brackets we'll take the square root of the coefficient of the x and the square root of the last number, then remove the square from the x and write it as a sum:
5(x+1.5)²
What's the idea behind this?
Well, remember that when you have something in the form:
(a+b)²
It actually means:
a² + 2ab + b²
In our case a was x, and b was 2.25. For bringing it into the shorter form we have to take the square root of a and b.
Sorry if you don't understand. Tell me if you need help to get the xoncept better.

Answer:
The price of the kilogram of cookies is $ 1.8
Step-by-step explanation:
Call x the price of the kilogram of candy and call y the price of kilogram of cookies
Then we know that

We also know that the price of kilogram of cookies is 1.40 dollars cheaper than the kilogram of candy
So

We solve this equation for x and then we substitute it in the first equation.



Answer:
Adding all the numbers together and dividing by the number of numbers
Example:
1, 3, 5, 6, 6, 6, 8, 8, 35, 46
Adding them together results in 124
124 divded by the number of numbers is 124 / 10 = 12.4
So the mean / median in this example is 12.4
