Answer:
The measure of the 3 angles is 36.9, 53.1 and 90 degrees.
Step-by-step explanation:
5^2 = 3^2 + 4^2 so , by the inverse of Pythagoras Theorem, this is a right angled triangle so one angle is 90 degrees.
We can find the other 2 angles using trigonometrical ratios.
One angle will have a sine of 3/5 and the other a sine of 4/5.
So the angles are arcsin 3/5 = 36.9 degrees and the other is arcsin 4/5 = 53.1 degrees.

Answer:
Since 95% confidence interval contains 0 we conclude at 95% confidence level that the two means are equal.
Step-by-step explanation:
Given that in a fast food study a researcher finds that mean sodium content of 32 Wendy's fish sandwiches is 1080 milligrams with a standard deviation of 75 milligrams. The mean sodium content of 39 Long John Silver's fish sandwiches is 1120 milligrams with a standard deviation of 100 milligrams
H0: The two means are equal
Ha: The two means are not equal
(Two tailed test at 5% level)
Variable A Variable B
Mean 1080.00 1120.00
SD 75.00 100.00
SEM 13.26 16.01
N 32 39
95% CI: -82.65 to 2.65
Since 95% confidence interval contains 0 we conclude at 95% confidence level that the two means are equal.
