Answer:
B = 150
Step-by-step explanation:
Since angles A and B are opposite interior angles, they are congruent.
8x - 10 = 3x + 90
8x - 3x = 90 + 10
5x = 100
x = 20
Now that we have the value of x, we have to solve for angle B.
B = 3x + 90
B = 3*20 + 90
B = 60 + 90
B = 150
Answer:
790
Step-by-step explanation: i just got it from someone else
Answer: Most likely (A) and (D)
Well, he recaptured 3 out of the 7 he marked. We can presume that the other 5 are gone. The population would be 8 robins, because 4 of the robins Julius marked were not recaptured. Therefore, the population is around 8-10 robins.
here is the data set for the complete question
x: 18 21 19 21 20 21
y; 2 14 5 6 18 18
Answer:
B. 0.652
Step-by-step explanation:
x y rank of x rank of y d d²
18 2 1 1 0 0
21 14 4 4 0 0
19 5 2 2 0 0
21 6 4 3 1 1
20 18 3 5.5 -2.5 6.25
21 18 4 5.5 -1.5 2.25
∑d² = 8.5
rs = 1 - 6[∑di² + ∑m(m²-1)]/n(n²-1)
= 1 - 6[8.5 +{3(3²-10/12 + 2(2² - 1)/12}]/6(6²-1)
= 1 - 0.348
= 0.652
therefore option b is the right answer.
