You need the Law of Sines for this. In our case we have the measure of angle B and side b, we have the measure of angle A and are looking for side a, or x. Setting up the Law using our info, we have $\frac{x}{sin(42)} = \frac{9}{sin(29)}$ . We will solve for x by multiplying both sides by sin(42): $x= \frac{9sin(42)}{sin(29)}$ , first choice above.

Dr. Park is interested in how the functioning of the brain changes with age and how this, in turn, affects older individuals’ me

Answer:

Option C. No, because the two populations from which the samples are selected do not appear to have equal variances.

Step-by-step explanation:

The variance measures how far a set of (random) numbers are spread out from their average value.

The fact that the younger adults show diversity in their brain activity while the older adults produce similar activities show that there are no equal variances in the two populations from which the samples are selected.

Therefore it would not be valid for Dr. Park to use the independent-measures t-test to test whether the brain activity of younger adults is different from that of older adults during a visual recognition task
