"Large Sample Proportion Problem. Surveys were conducted in multiple countries and respondents were asked if they felt political
melomori [17]

Answer: 0.0158

Step-by-step explanation:

Given : The data for the United States is that out of 1,000 sampled, 470 indicated yes, they felt political news was reported fairly.

According to the given information we have,

Sample size : n= 1000

Sample proportion: \hat{p}=\dfrac{470}{1000}=0.47

The standard error for proportion is given by :-

S.E.=\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

S.E.=\sqrt{\dfrac{0.47(1-0.47)}{1000}}

S.E.=\sqrt{0.0002491}

S.E.=0.0157829021412\approx0.0158

[Rounded to the nearest four decimal places.]

Hence, the standard error for the confidence interval = 0.0158

Please help if you understand!! I hope everyone has a great day or is having a great day​
Monica [59]

Answer:

Firstly, notice the relationship the two triangles have. They have conjoining ends that form vertical angles (looks like a middle x). Vertical angles are equivalent in measure of degrees.

Secondly, notice that the triangle on the right side is a right triangle. One of its angle's measurements are also given; 40 degrees. If you know that the sum of a triangle's angles equal 180 degrees, then simply subtract the known angles measurements from 180.

180-(90+40)=  180-130=50.

Therefore, the vertical angles measurement is equivalent to 50 degrees.

Apply the principle of the sum of all angles in a triangle equivalent to 180 degrees to the left triangle, and you will be able to find the measurement of the "?" angle.

180-(50+25)= 180-75=105

SO HERE IS YOUR ANSWER= 105 degrees is the value of the angle marked with a "?"

I hope you are having a great day too;)!
