Answer:
x = 4
Step-by-step explanation:
Given that sin(13x) = cos(9x+2)
Since sintheta = cos(90 - theta)
hence sin (13x) = cos (90 -13x)
Substitute into the original equation
cos (90 -13x) = cos(9x+2)
90-13x = 9x+2
-13x - 9x = 2 - 90
-22x = -88
x = 88/22
x = 4
Hence the value of x is 4
The probability that the sample mean would be less than 40.6 dollars will be 0.534.
<h3>What is a normal distribution?</h3>
The Gaussian distribution is another name for it. The most significant continuous probability distribution is this one. Because the curve resembles a bell, it is also known as a bell curve.
The z-score is given as
z = (x – μ) / σ
The mean cost of a five pound bag of shrimp is 40 dollars, with a standard deviation of 7 dollars.
If a sample of 51 bags of shrimp is randomly selected.
Then the probability that the sample mean would be less than 40.6 dollars will be
z = (40.6 – 40) / 7
z = 0.0857
Then the p-value will be
P(x < 40.6) = P(z < 0.0857)
P(x < 40.6) = 0.534
