By the external angle of a triangle theorem 142 = w + 49

So w = 142 - 49 = 93 degrees (answer)

Sum of angles of a linear pair = 180. So angle with measurement 142 and the adjacent angle to it have a sum = 180.

THerefore 142+y=180

Subtracting 142 from both sides

y = 38

Now in the down right sides corner triangle

38+49+w=180

87+w=180

Subtracting 80 from both sides,

w = 93

So the measurement of angle w = 93 .

We wish to construct a 90% confidence interval on the mean of a population known to be normally distributed based on a sample of

sergiy2304 [10]

Answer:

Margin of error = 0.773

Step-by-step explanation:

We are given the following information in the question.

Sample size, n = 20

Sample mean = 8

Sample standard deviation = 2

90% Confidence interval

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 19 and}~\alpha_{0.10} = \pm 1.729$

Margin of error:

$t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$1.729(\frac{2}{\sqrt{20}} ) = 0.773$

The answer is $2.50 because you do 145-132.50=12.5
Then you divide by 5 because that’s the difference between students then the final answer is 2.50
