She then paints her nails with Brand A and her sister's nails with Brandb. She compares the nails polish at the end of the week and determines that Brand B last longer because there fewer chips than Brand
a. Why is her conclusion not valid?
Answers
Answer:
She painted her sister's nails with Brand B, not her own nails.
Step-by-step explanation:
All parts to an experiment must be the same except one thing. She is testing different nail polishes so that's what needs to be different. By painting her hand with one nail polish and her sister's with the other, she is changing a second variable in the experiment making it invalid.

If you would like to know how many of each type of ticket were sold, you can calculate this using the following two equations:
a ... the number of drakes fan club tickets
s ... the number of no members tickets
$550 = a * $20 + s * $25 ... 550 = 20 * a + 25 * s
a + s = 25 ... a = 25 - s
__________________
550 = 20 * a + 25 * s
550 = 20 * (25 - s) + 25 * s
550 = 20 * 25 - 20 * s + 25 * s
550 - 20 * 25 = 5 * s
550 - 500 = 5 * s /5
s = 50 / 5
s = 10 tickets
a = 25 - s = 25 - 10 = 15 tickets
Result: There were 15 drakes fan club and 10 no members tickets sold.

The loss percentagea company incurs when buying an asset for rs. 1,50,000 and selling it for rs. 75,500 is 49.7%.
The loss percentage is calculated by subtracting the selling price from thepurchase price , then dividing that result by the purchase price, and finally multiplying by 100 to get the percentage format. In this case, it's a business scenario involving the purchase and sale of an asset, so the formula is appropriate
You can use it as follows:
Loss% = [(1,50,000 - 75,500) / 1,50,000] * 100
When you calculate the expression in the square brackets you get 0.497, or 49.7%.
So, in the provided scenario, the company incurred a loss percentage of 49.7%.
This means that the company lost nearly half of the initial value of the asset when they sold it.
