A researcher recorded that a chemical reaction required 2.90 gal water and raised the temperature of the reaction vessel by 57 F
Bess [88]

<em>A. 11.0 L is the researcher's volume measurement to the SL units of liter</em>

<u>Explanation:</u>

Given that a researcher recorded that the chemical reaction has water = 2.90 gallon.

We have to convert the researcher's volume into the SL units of liter.

<em>So, we know that 1 gallon = 3.875 liters</em>.

Then we have to convert 2.90 gallons of water in to liters.

Then  , volume in L =(volume\ in \ gal) \times  (3.875 L/1 gal)                                   = (2.90) \times (3.875L/1 gal)                                  

= 11.0L

<em>Then the required volume in L= 11.0L</em>

olchik [2.2K]

Answer:

C. About 18 percent of the variation in blood pressure can be explained by a linear relationship between blood pressure and caffeine consumed.

Explanation:

Here, r = 0.428

∴ We can say it will give a positive curve, as 0.428 indicates it is a positive correlation.

Though the amount of correlation is low, still it is positive and more than 0.4

So, nearly about 18% of the variation in the blood pressure can be observed by the consumption of caffeine water. As consumption of caffeine water and blood pressure is both increasing so we can say that r= 0.428 will give a positive linear curve.
