Answer:
[22.57 ± 2.776]
Step-by-step explanation:
Hello!
You have the 95% Confidence Z-interval (21.182;23.958), the mean X[bar]= 22.57 and the sample size n=25.
The formula for the Z interval is
[X[bar] ± ]
The value of Z comes from tha standard normal table:
The semiamplitude (d) or margin of error (E) of the interval is:
E or d= (Upperbond- Lowerbond)/2 = (23.958-21.182)/2 = 2.776
[X[bar] ± E]
[22.57 ± 2.776]
I hope it helps!

Answer: 12/13</h3>
The sine of an angle is equal to the opposite over hypotenuse
sin(angle) = opposite/hypotenuse
sin(x) = 12/13
The answer to the equation is 4x-5. This is called expanding brackets. So you have to do 2x times by 2 then u do 3x2 so whatever is on the inside u multiply it by the outside. If the answer is negative I must put a minus instead of plus
