What is the value of y?

NNADVOKAT [17]

Answer:

y = 40

Step-by-step explanation:

Lets make an equation to represent the sum of the angles:

We know that the sum of angles of triangles equals 180 degrees. So based on this knowledge, the equation is :

2y + y + 10 + 50 = 180

Now we simplify:

2y + y = 3y

10 + 50 = 60

So our new equation is 3y + 60 = 180

Now all we have to do is simplify:

3y + 60 = 180

3y + 60 -60 = 180 - 60

3y = 120

3y / 3 = 120 / 3

y = 40

So the answer is 40 hope this helped

Answer:

The 95% confidence interval for the true proportion of Gastown residents living below the poverty line is (0.133, 0.2766).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence interval $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

Z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

He takes a simple random sample of 122 people living in Gastown and finds that 25 have an annual income that is below the poverty line. This means that $n = 122$ and $\pi = \frac{25}{122} = 0.205$

We have $\alpha = 0.05$ , z is the value of Z that has a pvalue of $1 - \frac{0.05}{2}$ = 0.975, so $Z = 1.96$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.205 - 1.96\sqrt{\frac{0.205*0.795}{122}} = 0.133$

The upper limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.205 + 1.96\sqrt{\frac{0.205*0.795}{122}} = 0.133 = 0.2766$

The 95% confidence interval for the true proportion of Gastown residents living below the poverty line is (0.133, 0.2766).
