Answer:
The weight of the turtles together is
Step-by-step explanation:
we know that
To find out the weight of the 2 sea turtles together, adds the weight of one turtle plus the weight of the other turtle and then round to the nearest hundred
step 1
Adds the weight of the two turtles
step 2
Round to the nearest hundred
Remember that
To Round a number
a) Decide which is the last digit to keep
b) Leave it the same if the next digit is less than (this is called rounding down)
c) But increase it by if the next digit is or more (this is called rounding up)
In this problem we have
We want to keep the digit
The next digit is which is 5 or more, so increase the "4" by 1 to "5"
therefore
The weight of the turtles together round to the nearest hundred is
<span>A+B)^2 is the largest. It is A^2+2AB+B^2, which is clearly greater than the last two options. To compare (A+B)^2 and 2(A+B), we remove one A+B so that we're just comparing A+B and 2. As A+B must be at least 3 (as both must be positive integers, and one must be greater than the other, leading to a minimum value of A=2, B=1), A+B is greater than 2, and as a result, (A+B)^2 is always the largest.</span>
Linear Regression is an approach for modeling the relationship between a scalar dependent variable y and one or more explanatory variables denoted x. the case of one explanatory variable is called simple linear regression
Answer:
n = -11
Step-by-step explanation:
Assuming you need to solve for n:
12 - n = 23 (Given)
-n = 11 (Subtract 12 on both sides)
n = -11 (Divide -1 on both sides)
