Trigonometric Ratios
A right triangle is defined as a triangle that has one interior angle with a measure of 90°.
The trigonometric ratios are defined as relationships between sides and angles on right triangles.
To better explain the required ratio, we'll include the following image that contains the given triangle, as described in the question:
The cosine of the angle T (shown in the figure) is defined as:
The secant of an angle is the reciprocal of the cosine, thus:
The adjacent side to angle T is 77 and the hypotenuse is 85, thus:
Answer:
a)the proportion of student is 0.1082
b)
H1: p = .08
H2: p not equal to 0.08
H1: p =0 .08
H2: p < .08
H1: p =0 .08
H2: p >0 .08
c)z=1.45
d) the p value is 0.1470
e)null hypothesis cannot be accepted,There is no enough evidence to reject the null hypothesis.

Answer:
B
Step-by-step explanation:
f=120p
f=120(16)
f= 1920
y=7 i got this answer cause i realized that 12 is only 3 numbers away from 9 so i added 3 to 4 and 3+4=7

Answer:
2.5 times per hour, on average
{0:00, 0:24, 0:48, 1:12, 1:36} then repeating at 2:00
Step-by-step explanation:
The least common multiple of the intervals is ...
LCM(8, 12) = 8·12/GCD(8, 12) = 8·12/4 = 24
The two buses will stop at the same time every 24 minutes. That is 60/24 = 2.5 times per hour.
Starting with the 6:00 am stop, the next joint stop is at 6:24, then 6:48. In the next hour, the stops are at 7:12 and 7:36. This sequence of times repeats, starting at 8:00 am. That is, the cycle repeats every 2 hours.
