1. Answer A and C
2. Answer B
Sorry if I’m wrong
The probability is 4/12 or 1/3
because the total of fish is 12 and the platy fish is 4 or 4 parts of the total 12.<span />
Y = a sin b x
amplitude = a
period = 2π /b.
<span>y = 6 sin x
a = 6
b = 1
</span>
a, the amplitude, represents the highest point a graph reaches;
a = 6
The period represents the length of a cycle-
the period = 2π /b = 2π/1 = 2π
Answer:
Step-by-step explanation:
First one
130 + 20x > 350 x = 11 20 * 11 = 220 130 + 220 = 350 11 weeks
Second one
30 + 15x > 90 x = 4 15 * 4 = 60 30 + 60 = 90 4 or more hours
Hope this helps :)
