Option C is the right answer.

The missing graph has been attached with the answer.

<h3>What is a Scatter Plot ?</h3>

These are Cartesian Points and it represents relationship between two variables.

It is given that

Will's Hypothesis is time can never be a dependent variable.

Although from the graph plotted it can be seen that the time is dependent on distance travelled and

the in a scatter plot , the dependent variable is plotted on y axis and here the time is plotted on y axis ,

therefore the scatter plot invalidate Willis’s hypothesis.

It invalidates his hypothesis because it is possible for the time a trip takes to depend on the distance that is traveled during the trip.

Hitman42 [59]

Answer:

Alexandria requires 55 rows to use all the shells.

Step-by-step explanation:

Given:

Number of Shells = 329

Number of shells in each row = 6

We need to find the number of rows she need if she wants to use all the shells.

Solution:

Now we know that;

number of rows she needs can be calculated by Dividing Number of Shells with Number of shells in each row.

framing in equation form we get;

number of rows = \frac{329}{6} = 54.83 \approx 55

Hence Alexandria requires 55 rows to use all the shells.

(3.125) + (-3.9) - (2.46)
lara31 [8.8K]

Answer:

<h2><u><em>-3.235</em></u></h2>

Step-by-step explanation:

First, let's start by removing the parentheses and simplifying the expression.

3.125 + - 3.9 - 2.46

Adding a negative number is the same as subtracting it, so we can remove the + sign.

3.125 - 3.9 - 2.46

From there, we can do simple subtraction and get:

-3.235
