All triangles have angles that add up to 180, so we can take the top triangle, which has angles 14, 45, and x, and say they add up to 180, so 180-14-45=x and x = 121. For E, all angles that look like that and have opposite angles, then these opposites are equal, so both sides of E are 121. then we use the bottom triangle to solve for D with the fact that all triangles' angles add to 180 again. 180-27-121 = D, so D=32

Answer:
0.025 is the standard error of mean.
Step-by-step explanation:
We are given the following in the question:
Sample size, n = 100
Sample mean = 13 psi
Population standard deviation = 0.25 psi
We have to find the standard error of the mean.
Formula:
Standard error =
0.025 is the standard error of mean.
Answer:
t would be steeper
Step-by-step explanation:
Hello!
To find this you have to find what 55% of 20 is
You can do this by doing 20 * 0.55
0.55 is 55% as a decimal
This gives us the answer of 11
Hope this helps!
