What is the least common multiple (LCM) of 8 and 10?
Svet_ta [14]

Answer:

LCM (8,10) = 2 × 2 × 2 × 5 = 40

Step-by-step explanation:

Least common multiple is the smallest number that is multiple of both the given numbers.

Example: LCM of 2 and 3 is 6 .

6 is a multiple of both 2 and 3 .

Given numbers are 8 and 10

First write both in factor form,

⇒ 8 = 2 × 2 × 2

⇒ 10 = 2 × 5

We find LCM by writing common terms one times and multiplying all terms together,

Here, 2 is common to both 8 and 10 so we write it once only.

Thus, LCM (8,10) = 2 × 2 × 2 × 5 = 40.

The graph shows the pounds of fruit and vegetables purchased by shoppers who bought both. (8th Grade Math)
vaieri [72.5K]

Because there is no pattern in the graph, we conclude that there is no correlation between the two variables, thus, the correct option is C.

<h3>What statement correctly describes the graph?</h3>

In the horizontal axis, we can see the pounds of fruit bought, while on the vertical axis we can see the pounds of vegetables bought.

If you see the graph, you can see that there is no pattern. Meaning that there is no relation between these two quantities.

So there is no correlation between the variables "pounds of fruit bought" and "pounds of vegetables bought.".

Then the correct option is C.

<em>"There is no association between the pounds of fruit purchased and the pounds of vegetables purchased"</em>
