Which phrase is the best description of the association between variables X and Y?

Mathematics
1 answer:
Elodia [21]3 years ago

The variables have a negative association/correlation, because when one value increases (ex: x) the other decreases (see y)
If you would put a line through the dataset most of the points would be quite a bit off the line so the association is only moderate and not strong

so the answer is it is a "moderate negative association"

For every 1 litre of water used to make a medicine, 193ml of sucrose and 61ml of saline solution are used. Express the amount of
Brilliant_brown [7]
<h3>Answer is the ratio 1000:193:61</h3>

Explanation

1 liter = 1000 mL

For every 1000 mL of water, we need 193 mL of sucrose and 61 mL of saline solution.

The ratio is therefore 1000:193:61

We cannot simplify this ratio any further because the GCF of those three terms is 1.

A quick way to see this is to look at how 1000 = (2*5)^3 has prime factors 2 and 5, but 2 nor 5 are factors of 193 and 61. So only 1 is a factor of all three values 1000, 193, 61

What value of x is in the solution set of 9(2x + 1) &lt; 9x – 18?
fredd [130]
To solve these kinds of problems, it is necessary to isolate x:

9(2x + 1) <span>< 9x - 18

Distribute 9:
18x + 9 </span><span>< 9x - 18

Subtracting 9 from both sides of the equation:
18x + 9 - 9 </span><span>< 9x - 18 - 9
18x </span><span>< 9x - 27

Subtracting 9x from both sides of the equation:
18x - 9x </span><span>< 9x - 27 - 9x
9x </span><span>< -27

x </span><span>< -3

Therefore, values of x </span><span>< -3 will satisfy the given equation.</span>
