Step-by-step explanation:
Easiest and fastest way to do this is to plug it into the calc because the log base 10 of those numbers given will be nasty decimals.
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.
C. 8
You substitute 8 into x, which makes the equation 5(8-5) = 15. 8-5 is 3, and 5 x 3 = 15.

Please mark be brainliest and I hoped this helped!
x = 45°
Step-by-step explanation:
Since this is an isosceles triangle, that means that x, and the angle opposite from x, are the same. We take 135° and subtract that from 180°. That gives us 45°. Since the angle opposing x is 45°, then x is 45° as well.
