Answer:
y= 4 sinx/2-3
Step-by-step explanation:
y= a sin2πt/T
where : a is the amplitude , t is the time in seconds, and T is a period of wave is seconds.
y=A sin (B(x+C)) +D
amplitude A = 4
2π/B is period = 4
C is the phase shift = -2
D is vertical shifts = -2
now substitute the numbers in the equation :
y= A sin ( B(x+C)) + D
y= 4 sin (4(x-2) -2
y=4sin(4x-8)-2
Answer:
1- P(-0.47 < z < 0.47) = 0.63836
Step-by-step explanation:
Here, we want to get the answer to;
1-P ( -0.47 < z < 0.47)
Mathematically, we are going to use the standard normal distribution table for this
Let us try to evaluate;
P(-0.47 < z < 0.47)
Mathematically, that will be;
P (z < 0.47) - P(z < -0.47)
where P (z < -0.47) = P( z > 0.47)
so we have
P(-0.47 < z < 0.47) = P(z < 0.47) - P(z > 0.47)
So we have this using the standard normal distribution table as follows;
0.68082 - 0.31818 = 0.36164
Now, we can insert this in the earlier expression of;
1- P(-0.47 < z < 0.47)
= 1-0.36164 = 0.63836
