Answer:
Norman bought the shoes for $117.72
Step-by-step explanation:
In order to find the answer to this question, start by multiplying the cost by the markup.
$90 * 20% = $18.
Now we add the $18 to the original price.
$90 + $18 = $108
Now that we have the mark up price, we need to do the same using the tax.
$108 * 9% = $9.72
Finally, we add that to the previous total.
$108 + $9.72 = $117.72
The answer is 13!

Using the mean <u>formula and it's interpretation</u>, it is found that:
1. The mean is 7.52.
2. If we were to give this quiz to more and more students, the mean score for these students would approach 7.52.
The mean of a discrete distribution is given by the <u>sum of each outcome divided by it's respective probability</u>.
Hence, in this problem, according to the <u>distribution given</u>, the mean is:

The mean is 7.52.
The <em>interpretation </em>is that over many trials, the mean would approach 7.52.

Answer:
4
Step-by-step explanation:
The function is given as 5c+cd, c=1/5 and d=15d.
We evaluate by substituting the given values of c and d in the function:


After substituting, we find the function's equivalent as 4.
Hence, the value of the function is 4
ᴇǫᴜᴀᴛɪᴏɴ: 12x - 30 = 6
value of x .
➦ 12x - 30 = 6
➦ 12x = 30 +6
➦ 12x = 36
➦ x = 36 /12
