Answer: 2:45
Step-by-step explanation: You add 30 minutes to 1:00, which is 1:30. Next, add 45 to 1:30, which is 2:15. Then, add 30 to 2:15 and you get 2:45!
Answer:
2
Step-by-step explanation:
Pull out like factors :
2x - 4 = 2 • (x - 2)
(4x + (2 • (x - 5))) - 6 • (x - 2)
(4x + 2 • (x - 5)) - 6 • (x - 2)
Final Answer:
2

1. the common formula for this graph is y=A*cos(Bx), where A - the amplitude, B - the frequency of the given function.
2. The max. and min. vertical values are 4 and (-4), it means that the amplitude is 4 (A=-4*),
for the function y=cosx the period is 2π, it means for the given function the period is π/2, it is for its frequency 2π/(π/2)=B=4.
* if to see to the suggested graph, the max. of cos4x are in points π/4+πn, and the min. are in π*n/2, it means that it need to add '-' in the equation of the function.
3. answer: y=-4cos4x.

Answer: 7 / 18
Step-by-step explanation:
There were 18 students.
Out of them, the scores above 65 are:
73, 73, 69, 68, 71, 76, 70
There are 7 of them.
Probability of picking someone who scored higher than 65 is:
= Number of people who scored above 65/ Total number who took the test
= 7 / 18
