Answer:
x=70; y=55
Step-by-step explanation:
So with the triangle with x, you can tell that the triangle is an icoceles based on how 2 of it's sides are equal lengths.
And so, an icoseles traingle also has two of the same angles so you can say that
55+55+x=180
110+x=180
x=70
Now the triangle with y is also an isoceles, and you can see that there is a verticle angle pair.
So,
y+y+70=180
2y=110
y=55
and to double check,
55+55+70=180
110+70=180
180=180

The 99% confidence interval for the proportion of US adults believing that raising the minimum wage will help the economy, based on a survey, is approximately (0.386, 0.454).
To compute the 99% confidence interval for the parameter of interest - the true proportion of adults believing that raising the minimum wage will help the economy - we use the formula for the confidence interval for a proportion: p ± Z*(sqrt((p(1 - p))/n)). Here p is the sample proportion, n is the sample size and Z* is the Z score corresponding to the desired confidence level, in this case 99%.
The given sample proportion (p) is 0.42 and the sample size (n) is 1000. The Z score for a 99% confidence interval is approximately 2.58.
Substituting these values into the confidence interval formula yields: 0.42 ± 2.58 * sqrt((0.42(1 - 0.42))/1000). After computation, we obtain the 99% confidence interval as (0.386, 0.454).
