Answer:
C) B = 38.8°, C = 93.2°, c ≈ 43
Step-by-step explanation:
For triangle: a / sin A = b / sin B = c / sinC
32 / sin 48° = 32 / 0.743
32 / 0.743 = 27 / Sin B sin B = 0.627
<u>B = 38.8°</u>
C = 180 - 48 - 38.8 = 93.2° sin C = sin 93.2° = 0.998
32 / 0.743 = c / 0.998 = 42.98 (<u>≈ 43</u>)
Answer:
C with 3000 successes of 5000 cases
Step-by-step explanation:
In test statistics the number of samples goes a long way in determining the result of a test.
Using the z score formula
Test statistic z score can be calculated with the formula below;
z = (p^−po)/√{po(1−po)/n}
Where,
z= Test statistics
n = Sample size
po = Null hypothesized value
p^ = Observed proportion
Therefore the z score is directly proportional to the square root of the sample size.
z ∝ √n
The higher the sample size, the higher the z score, the higher the evidence of confirming the alternative hypothesis.
Since the all have the same proportion (0.6), and options c has the highest sample size (5000 cases), it will give the strongest evidence for the alternative hypothesis
Answer:
The number is 10
Step-by-step explanation:
Let x represent the unknown number
4+2+x=16
6+x=16
6+x-6=16-6
x=10
