As y varies inversely with x, we have a function of the form:
y = k / x
We must find the value of k:
For this we substitute y = 5 when x = 5.
We have then:
5 = k / 5
k = 5 * 5
k = 25
Then, the function is:
y = 25 / x
Answer:
the inverse variation function is:
y = 25 / x

Step-by-step explanation:
Mean 49
Mode 45
Median 50
range is 5
Explanation:
Put the numbers in order
45,45,47,50, 51,52,53,
The number that happens MOST the MODE is 45
The number in the MIDDLE, the MEDIAN is 50
The MEAN is the total of the 7 numbers shared out evenly.
Total 343
343 Divided by 7 =49
Answer:
Explanation:
You can convert the percent markup into a multiplicative factor in this way:
Base price: 15,800 . . . (cost to the seller)
Percent mark up: 115% . . . (based on the cost to the seller)
Sale price: 15,800 + 115% of x = 15,800 + 115 × 15,800 /100 =
= 15,800 + 1.15 × 15,800 = 15,800 (2.15) = 33,970
The markup is:
- Markup = price paid by the seller - cost to the seller = 33,970 - 15,800 = 18,170 (notice that this is 115% of 15,800)
And <em>the percent markup based on the sale price is</em>:
- % = (markup / sale price) × 100 = (18,700 / 33,970) × 100 =
= 53.49 %
Rounding to the nearest tenth percent that is 53.5 %.
Answer:
0.16 can be written with 100 as the denominator.
16/100
To simplify, divide the top and bottom by 4.
4/25
