The half-angle formula for cosine is
To find cos(3π/8), we can use this formula with θ=3π/4. Cos(3π/4) = -(√2)/2, so we have

Answer:
The standard error of the mean for this sample is 9.033
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean and standard deviation
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean
and standard deviation
.
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
In this problem, we have that:
So
The standard error of the mean for this sample is 9.033
Answer:
5.31
Step-by-step explanation:
Given the regression line equation, , where,
x = number of slices of pizza eaten
y = number of laps run immediately
Number of laps run by a player who ate 7 slices of pizza can be predicted by plugging in x = 7 into the regression line equation to find y:
