We would start with 400 - 48, to cover the initial cost. We would be left with 352 dollars to spare for the monthly bill. 352 divided by 44, which is the monthly cost, would be 8. The website could be set up and held for 8 or 9 months, depending on if the initial cost is paid at the same time or before the first monthly one.
Answer:
<em>A normal distribution</em> is a general distribution that represents any normally distributed data with any possible value for its parameters, that is, the mean and the standard deviation. Conversely, <em>the standard normal distribution</em> is a specific case where the mean equals zero and the standard deviation is the unit. That is why we can refer to <em>a normal distribution</em> and <em>the standard normal distribution</em>.
Step-by-step explanation:
We have to remember that <em>a normal distribution</em> has two parameters that define it, namely, <em>the mean</em> and <em>the standard deviation</em>, and there are, theoretically, infinite possible means and standard deviations, so we tell about <em>a </em>normal distribution in general.
Conversely, <em>the</em> standard normal distribution is <em>a normal distribution</em> with a mean = 0 and a standard deviation = 1, and we also have to remember that is possible to 'convert' or 'transform' any raw score from any normally distributed data into a z-score to find its probability using <em>the</em> standard normal distribution. The formula for a z-score is as follows:
Where

.
In other words,<em> the standard normal distribution</em> is a specific case for normally distributed data whose values are standardized or represent distances from the mean in standard deviations units, and thanks to this, we can find any associated probability with these values for any possible normal distribution (see the graph below).

Step-by-step explanation:
Answer:
Perimeter = 54.6 cm
Area = 173 cm²
Step-by-step explanation:
sin 30 = x/20
x = 10
cos 30 = y /20
y = 17.3
perimeter = 10 + 17.3 + 10 + 17.3 = 54.6 cm
area = 10 * 17.3 = 173 cm²
