Express the confidence interval 0.319 < p < 0.488 in the form of p ± E.
1 answer:
Answer:
Step-by-step explanation:
The fundamental step would be to determine the values of p and E which i believe is the margin of error in this case. Consider the following two equations;
We simply add the two equations and solve for p;
We then substitute this value of p in either equation and solve for E;
Since we have both p and E, the confidence interval can thus be written as;

Point slope formula:
(y₂ -y₁) = m(x₂ - x₁)
(1 - 0) =
(4 - X)
1 =
-1 = X
(y₂ -y₁) = m(x₂ - x₁)
(1 - 0) =

-1 = X
Answer:
Step-by-step explanation:
We have the length of AC which is opposite angle B; we also have the length of the hypotenuse. We will use trig here to solve for angle B. The sin ratio is the one that fits.
sin(B) = side opposite / hypotenuse:
so
sin(B) = .9411764706
Now we will use the 2nd button on our calculators. This will give us the missing angle value. Press 2nd then sin and you will see on your screen:
Enter that decimal after the open parenthesis and hit "enter" to get
B = 70.25 or 70°
