Find the value for x <br> Can somebody help me? <br> Please
Katena32 [7]

Answer:

1-7 2-6 3-6 4-4

Step-by-step explanation:

To do this, you must notice that all of these are isosceles triangles (2 of the sides are the same.) You already have 1 value on each triangle, and the length of that side is the same length as the side with the unknown value, so those are the correct answers. If I made a mistake, please correct me. Everybody makes mistakes.

Answer:

(0.6430, 0.8170)

Step-by-step explanation:

Given that during a recent drought a water utility in a certain town sampled 100 residential water bills and found out that 73 of the residences had reduced their water consumption over that of the previous year.

Sample size n = 100

Sample proportion p = \frac{73}{100} =0.73

q = 1-p = 0.23

Std error of proportion = \sqrt{\frac{pq}{n} } \\=\sqrt{\frac{0.73*0.27}{100} } \\=0.04440

95% Z critical value = 1.96

Margin of error = 1.96*0.0444 = 0.0870

Confidence interval = sample proportion ±margin of error

0.642983946

0.817016054

(0.6430, 0.8170)
