Answer:
The ratios are both identical. (4 over 5 and 4 over 5)
Step-by-step explanation:
Th picture below represent the image you are referring.
sin x = opposite / hypotenuse
opposite side = 4
hypotenuse = 5
sin x° = 4/5
cos y° = adjacent/hypotenuse
adjacent = 4
hypotenuse = 5
cos y° = 4/5
The ratios are both identical (4 over 5 and 4 over 5)
Answer:
178
Step-by-step explanation:
The area of the rectangle is 6x25=150.
The area of the two semicircles on the sides is equal to the area of one circle with a radius of 3, so the area is which is approximately 28.27.
150+28.27=178.27

Given:
Dana found that 8 students earned an A, 6 students earned a B, 4 students earned a C, and 2 students earned a D on the last science test.
To find:
the experimental probability that the student would have earned an A in the test
Solution:
Probability refers to the chances of occurrence of some event.
Number of students who earned an A in the test = 8
Total number of students = 8 + 6 + 4 + 2 = 20
The experimental probability that the student would have earned an A in the test = Number of students who earned an A in the test / Total number of students =
