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.
"Bedding is the separation of sediments into layers that differ from one another in texture, composition, color, or weathering characteristics".
Option (b);
<u>EXPLANATION: </u>
Sediments mean the matter that gets accumulated in one place. Sedimentary rocks are the results of the rock due to the accumulation of small particles that get weathered from rocks or erosion over time. They get accumulated either on the bottom of the sea level or earth's surface and thus the sediment rocks are formed.
These layers of sediments that are created based on difference in their shape, size, color and composition results it in bedding.The size of rocks in bedding ranges from several millimetres to centimetres and it sometimes results in a meter thick.
