Answer:

-2

Step-by-step explanation:

As we move right from (-6,12) to (-2,4), x increases by 4 and y decreases by 8. Thus, the slope of the line thru these 2 pts is m = rise / run = -8/4 = -2.

The first answer choice is the correct one: The slope is -2.

A certain food has a gluten ratio of 13\,\text{mg}13mg13, start text, m, g, end text of gluten per \text{L}Lstart text, L, end t

irina [24]

Answer:

The gluten ratio in micrograms per milliliter is 13 µg/mL.

Step-by-step explanation:

Consider the provided information.

It is given that the food has a gluten ratio of $13 \frac{mg}{L}$ .

Now we need to convert gluten ratio in micrograms per milliliter

To convert mg to micro grams use the information shown below:

1 mg = 1000 micro-grams.

1 L = 1000 milliliter

Now, substitute 1 mg = 1000 micro-grams and 1 L = 1000 milliliter in the above ratio.

$13( \frac{1000 \ micro-grams}{1000 \ milliliter} )= 13( \frac{micro-grams}{milliliter})$

Hence, the gluten ratio in micrograms per milliliter is 13 µg/mL.

If the coefficient of correlation is .8, then the percentage of variation in the dependent variable explained by the estimated r

Olegator [25]

Answer:

64%

Step-by-step explanation:

The percentage of variation in the dependent variable explained by the estimated regression is calculated with the coefficient of correlation as follows:

First, square the coefficient of correlation: 0.8^2 = 0.64

And then, multiply this result by 100, so that, it is expressed as a percentage: 0.64*100 = 64%
