Xavier is testing different types of planting soil to determine which type is most effective in growing blueberry bushes. He pur
vladimir1956 [14]

Answer:

He did not control for lurking variables and their impacts on the results of his experiment. Amount of sunlight and water received are two outside variables(or confounding variables) that may impact the growth of his plants and influence the results. He needs to apply the same amount of sunlight and water to each plant within a different planting soil in order to rule out the influence of those two variables and test the sole effect of the soil brand on the plant growth. Otherwise, it would be hard to determine whether his plant growth was because of the soil brand or the different amounts of sunlight and water received

What is the approximate value of b, rounded to the nearest tenth? Use the law of sines to find the answer.
vivado [14]

You can use the Law of Sines for this problem, but what makes it tough at first glance is that they put a step in before you can use it directly. That first step is to get m∠C. When solving a triangle, always get the third angle if you know the other two so that you can use the Law of Sines (or Law of Cosines) more directly.


The sum of the angles of any triangles is 180°. We know the measures of the two other angles. So we subtract them from 180° to find that third angle.


180° - 76° - 66° = 38°


Now we can use the proportion from the picture. Angle B measures 76°, side b is our unknown, Angle C measures 38°, and side c measures 3 units.


sin 76° sin 38°

----------- = -----------

b 3


Cross multiply to find b (the side). We carry out five places in these calculations to get more accuracy.


3 * sin 76° = b * sin 38°


b = 3 * sin 76° 3 * 0.56611 1.69832

--------------- = --------------- = ---------------- = 5.73044

sin 38° 0.29636 0.29636


To the nearest tenth, b - 5.7 units.
