Answer:
3.
Step-by-step explanation:
The other 3 answers (1, 2, and 4) are taking samples from a defined group, and so it is not random and fair. For the first answer, you're looking into the population of the band members, and the same is for number 2. As for number 4 you're only limiting it to people that you know. For 3, you may be sampling from people you may or may not know, so everyone has the same rate of being sampled, which is fair.
Answer:
Below.
Step-by-step explanation:
Finding the hypotenuse:
Recall the formula of Pythagoras'theorem,
- (Hypotenuse)² = (Base)² + (Perpendicular)²
Given that base = 8 and perpendicular = 15
Plugging the values,we obtain
- H² = 8² + (15)²
- H² = 64 + 225
- H² = 289
- H = √(17*17)
- H = 17
Now applying trigonometric functions:
Recall SOHCAHTOA , it's very helpful.
Sin θ = Sin A = Opposite/Hypotenuse
cos θ = cos A = Adjacent/Hypotenuse
Tan θ = tan A = Opposite/Adjacent
Note: The values in decimal are rounded to nearest hundredth.
