Anit [1.1K]

Answer:

1) 64, 2) 6, 3) 26, 4) 33

Step-by-step explanation:

<u>Sum of interior angles is 180</u>

70 + 46 + x = 180
116 + x = 180
x = 64

<u>Sum of interior angles is 180</u>

84 + 7x + 1 + 9x - 1 = 84
16x + 84 = 180
16x = 96
x = 6

<u>Vertical angles are same, the sum of remaining angles is same for both triangles:</u>

35 + 25 = 34 + x
60 = 34 + x
x = 60 - 34
x = 26

<u>Exterior angle is same as the sum of non-adjacent interior angles:</u>

5x - 7 + 6x + 3 = 84
11x - 4 = 84
11x = 88
x = 8

m∠G = 5x - 7 = 5*8 - 7 = 40 - 7 = 33

GenaCL600 [577]

Answer:

95% Confidence interval: (0.8449,0.9951)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 50

Number of times the dog is right, x = 46

$\hat{p} = \dfrac{x}{n} = \dfrac{46}{50} = 0.92$

95% Confidence interval:

$\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting the values, we get:

$0.92 \pm 1.96(\sqrt{\dfrac{0.92(1-0.92)}{50}})\\\\ = 0.92\pm 0.0751\\\\=(0.8449,0.9951)$

(0.8449,0.9951) is the required 95% confidence interval for the proportion of times the dog will be correct.
