Answer:
20.24 cm
Step-by-step explanation:
Here, since the age of the crab is given in months and the regression line was computed using the age in months, we just have to replace the value of the age in the formula to estimate the size.
The formula obtained for the estimated size Y was
Y = 9.1411 + 0.4775X
where X is the age in months
Replacing X with 23.2417, we get
Y = 9.1411 + 0.4775*23.2417 = 20.24 cm
The inverse for this operation would be to find the equation for "x" since it's the equation for "y." Inverse means reverse in direction or position. To find the inverse of "y = -3/(x+4) , you would need to start by using the order of operations. Here's where you start:
y<span> = -3/(x+4)
</span>
Next, you want to get the (x+4) to the other side. Since it's being divided, multiply this number on both sides.
y = -3/(x+4) ⇒ (x+4)y = -3
Now, you need to get y on the opposite side. Divide both sides by y.
(x+4)y = -3 ⇒y÷ (x+4)y = -3 ÷ y
The y's cancel on the left, so you would have the equation:
x+4 = -3/y
Now to get x by itself, subtract 4 from both sides.
x+4 = -3/y
-4 -4
⇒x = -3/y -4 is your final answer.
Perimeter: P <span>= <span>4(a) </span></span><span>= <span>4 </span></span>× <span><span>2 </span></span><span>= <span>8
To find the area:
Perimeter </span></span>÷ 4 (since a square has 4 sides) = 2
Length of one side of a square = 2
Formula of area: length × width = area
Area : 2 × 2 = 4
The area of the square is 4
