Answer:

\boxed{\text{D. 11.6 lb}}

Step-by-step explanation:

The mean is the sum of the weights divided by the number of weighings.

\text{Mean}= \dfrac{13.5 + 12.5 + 10.5 + 11.2 + 11.2 + 10.8 + 9.5 + 13.4 + 11.5 + 11.8}{10}\\\\= \dfrac{115.9}{10} \approx \mathbf{11.6}\\\\\text{Heather is predicting that Sally will weigh } \boxed{\textbf{11.6 lb}}

5. A rectangular pool ha a length that is 13 meters longer than its width. perimeter is74 meters. What is the width Its of this
gregori [183]
Good evening Brian,

For this problem, let's look at what we're given.  So we have a pool with a length that is 13 m (meters) longer than its width, and we're given the perimeter, or distance around the entire pool, which is 74 m.

We know that the pool has a rectangular shape and that the perimeter of a rectangle is <span>width + length + width + length ⇒ 2(W) + 2(L)</span>.

Given the information provided, we can rewrite the equation to fit this problem.  Since we're told that the length is equal to 13 m + the width, so we can represent the length as W +13 m.  We can now rewrite the perimeter equation to be:

2(w) + 2 (w + 13 m) ⇒ 2(w) + 2(w) + 2(13 m) ⇒ 4(w) + 26 m = 74 m.

We're down to one variable now so this should be easy.  Subtract 26 m from both sides,

4(w) = 48 m

Now divide each side by 4 in order to find the width.

w = 12 m

-Hope this helps!
