2 answers:
The probability that the next person that visits the website will purchase more than 1 piece of artwork is .
Step-by-step explanation:
Step 1; The probability of an event is given by dividing the number of favorable outcomes i.e. the number of people that brought more than one piece of artwork by the total number of outcomes i.e. the total number of people that visited the website.
Step 2; The probability is calculated by the following values;
The number of favorable outcomes = the number of people that purchased more than one piece of artwork = 9
The total number of outcomes = The number of people that did not buy any artwork + the number of people that brought one piece of artwork + the number of people that brought more than one piece of artwork
= 117 + 24 + 9 = 150.
The probability that the next person that visits the website will purchase more than 1 piece of artwork = =

Answer:
3 in
Step-by-step explanation:
Sum of all sides of ∆ = perimeter
Given that it has a perimeter of 13 in, and the following sides: (x - 5) in, x/2 in, and 6 in, therefore:
Solve to find the value of x
Multiply both sides by 2
Subtract 2 from both sides
Divide both sides by 3
The shortest side = (x - 5) in
Plug in the value of x
= (8 - 5) in
= 3 in
A normally distributed data set has a mean of 0 and a standard deviation of 2. The closest to the percent of values between -4.0 and 2.0 would be 84%.
<h3>What is the empirical rule?</h3>According to the empirical rule, also known as the 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95%, and 99.7% of the values lies within one, two, or three standard deviations of the mean of the distribution.
A normally distributed data set has a mean of 0 and a standard deviation of 2.
