-12 and - 10
Step-by-step explanation:
Givens
Larger number = x
Smaller number = x - 2
Equation
x*(x - 2) = 120
Solution
Remove the brackets
x^2 - 2x = 120
Subtract 120 from both sides
x^2 - 2x - 120 = 0 Factor
(x - 12)(x + 10) = 0
x - 12 = 0
x - 12 + 12 = 12
the other number is 2 less than this one or x = 10
=================
x + 10 = 0
x = - 10
The number that is 2 less than this one is
x = -10 -2
x = -12

If the outliers are not included, what is the mean of the data set? 76, 79, 80, 82, 50, 78, 83, 79, 81, 82 (2 points) Select one

Hello!
As you can see, 50 is the outlier, as it is not around the other numbers in the data set. Therefore, we will calculate the mean of all the numbers if we add up all the numbers and divide by 9.
(76+79+80+82+78+83+79+81+82)÷9=80
The mean of this data set (excluding the outlier) is 80.
I hope this helps!
So, I converted the grams to kilograms, and the smallest cat was the Canada Lynx, being 15.9kg and the largest cat was the mountain lion, which was 85kg. So since it asks for the difference, we subtract.
85-15.9=69.1
Therefore the answer is B. 69.1kg
