Answer:
yes
Step-by-step explanation:
The answer is Demographic data
The researcher includes the following material in a research report: The seven males varied in age from 32 to 45 (M = 38), had a high school education (two had high school diplomas, one had an associate degree, three had an undergraduate degree, and one had a master's degree), and had yearly incomes ranging from $20,000 to $100,000 (M = $52,000). Demographic data refers to information on the characteristics of the individuals being investigated.

Answer:
a. 7.64 km/h
b. 6.0°
c. see below
Step-by-step explanation:
a) The total velocity of the boat is ...
7i +(0.6i +0.8j) = 7.6i +0.8j
The magnitude of this velocity is the speed of the boat, relative to land. That is given by the Pythagorean theorem.
|7.6i +0.8j| = √(7.6² +0.8²) = √58.4 ≈ 7.642 . . . . km/h
__
b) The angle of the total velocity with respect to the "i" direction (the direction of vector v) is ...
α = arctan(0.8/7.6) ≈ 6.009°
__
c) The boat is headed in a direction 6° different from its velocity relative to the water. That may need to be accounted for if the boat is traveling any significant distance.
