Its C.
Triangle A is straight up and down and then when you rotate it 90 degrees at point C,It becomes point B.
To solve this, you basically just look at what point it is rotated at, then figure out how far it is rotated.
Hope this helps :)
14 2/5 as a decimal is 14.4
3/8 as a decimal is 0.375
14.4 ÷ 0.375 = 38.4 or 38 2/5
I'm pretty sure Cos(20°) = Sin(70°) Hope this helps :)
Answer:
f[g(x)] = 3x, which represents the money Anna made in dollars per hour.
Step-by-step explanation:
Anna is selling tickets to a carnival. The function f(x) = 0.5x represents the amount of money in dollars Anna earns per ticket, where x is the number of tickets she sells. The function g(x) = 6x represents the number of tickets Anna sells per hour, where x is the number of hours she works.
Hence, f[g(x)] = f(6x) = 0.5(6x) = 3x
Therefore, f[g(x)] = 3x, which represents the money Anna made in dollars per hour. (Answer)
z-score fore -1.2 = 0.1151
z-score for 0.85 = 0.8023
Subtract :
0.8023 - 0.1151 =0.6872
The answer is C.
