The answer c, because they got 9 out of 15 flips being heads. This probability is 0.6. The other answers are not accurate.
Answer:
x^2-4x+4-(x^2+6x+9)
Step-by-step explanation:
=x^2-4x+4-x^2-6x-9
=-10x - 5
Answer:
You can use a calculator to find all the tan, sin, cos values! Simply enter the number, for example, 52, then press the tan button! For question d, you are finding what number that decimal is the tangent of. Press the 2nd function on your calculator, and you can see that -1 beside the tan. Enter the decimal then use that button to find the reverse tangent.
tan52 = 1.2799
sin19 = 0.3256
cos34 = 0.8290
tan-1(0.9876) = 44.6426
To solve the conveyor belt problem, you'll have to use the sine of 15. (remember, sine = opposite/hypotenuse). Set up an equation:
sin15 = ?/12m
Use a calculator to find sin15, then you can solve it like algebra.
sin15 = ?/12m
sin15*12m = ?
0.2588*12m = ?
3.1056m = ?
Hope this helped :)
