Answer:
y=4.5
Step-by-step explanation:
The angles that are congruent to one are 4,5, and 8. So the answer would be B. 5.
1) Find the mean of the following numbers: 5, 11, 8, 8, 7, 4, 10, 9, 7, 7, 6
SashulF [63]
Mean = 5+11+8+8+7+4+10+9+7+7+6 divided by the number of observations which is 10
Therefore, mean = 73/10
Mean = 7.3
Answer:
0.9950 to the nearest ten thousandth.
Step-by-step explanation:
We use the identity sin^2 t = 1 - cos^2 t
sin^2 t = 1 - (0.1)^2
= 0.99
So sin t = 0.9950 (answer).
