Step-by-step explanation:
Let's say c is the price of cinnamon tea, and s is the price of spice tea.
10c + 2s = 13
16c + 8s = 28
Divide the second equation by 4:
4c + 2s = 7
Subtract from the first equation:
6c = 6
c = 1
Use any equation to find s.
s = 1.5
Therefore, the cinnamon tea costs $1 per pound and the spice tea costs $1.50 per pound.
The numerical values of the mean and standard deviation are 4 and 1.55, respectively
<h3>The
numerical value of the
probability that x = 6. </h3>
The given parameters are:
n = 10
π = 0.4
The probability is then calculated as:

So, we have:

Apply the combination formula

So, we have:

Evaluate
P(6) = 0.1115
Hence, the numerical value of the probability that x = 6 is 0.1115
<h3>The numerical values of the mean and standard deviation </h3>
The mean value is:

This gives


The standard deviation value is:

This gives


Hence, the numerical values of the mean and standard deviation are 4 and 1.55, respectively
