Answer:
-3.1, -3.2, -3.3, -3.4, -3.5, -3.6
Step-by-step explanation:
Answer:
∠Q ≈ 42.969, ∠P ≈ 52.03, QR ≈ 15.036
Step-by-step explanation:
Law of sines:
13/sin Q = 19/sin 85°
=> sin Q = 13 × sin 85°/19
=> Q = sin^-1 (13 × sin 85°/19)
=> Q ≈ 42.969
∠P=> 180 - 85 - 42.969 ≈ 52.03
QR/sin 52.03° = 19/sin 85°
=> QR = sin 52.03° × 19/sin 85°
=> QR ≈ 15.036
it is 3.742, 3.742, 14.142
120° is the correct answer<span />
Answer:
<u>The sample that best represents the population is the sample of the last eight friends </u>
Step-by-step explanation:
Let's find out the sample that best represents the population, this way:
Mean of the number of text messages a group of 24 friends sent in one week = 10,700/24 = 445.83
Mean of the sample of the first six friends = 1,850/6 = 308.33
Mean of the sample of the first ten friends = 3,300/10 = 330
Mean of the sample of the last twelve friends = 6,500/12 = 541.67
Mean of the sample of the last eight friends = 4,150/8 = 518.75
<u>The sample that best represents the population is the sample of the last eight friends, because its mean is the closest to the population mean (445.83 and 518.75)</u>
