Hanadi buys a dishwasher for £240 she wants to put a tag with a price on the dishwashee so that in the sale she can give a disco

Elanso [62]

Answer:

Step-by-step explanation:

Original price that she paid for the dish washer is £240. She wants to sell it and make a profit of 25%. It means that price at which she would make a profit of 25% is

240 + 25/100 × 240 = 240 + 60 = 300

To determine the price tag of 40% discount and that would still ensure that she makes £300,

Let x represent the price tag in £. It means that a discount of 40% on £x would be 300. A discount of 40% on £x is expressed as

x - (40/100 × x) = x - 0.4x = 0.6x

So 0.6x = 300

x = 300/0.6 = 500

So the price tag will be £500

The mean of the scores obtained by a class of students on a physics test is 42. The standard deviation is 8%. Students have to s

NemiM [27]

The correct answer is:
16%.

Explanation: 
We use a z-score to answer this question.
The formula for a z-score is:
z= $\frac{x-mue}{sigma}$ ,
where mue is the mean and sigma is the standard deviation.

Using our information, we have:
z= $\frac{50-42}{8} = \frac{8}{8} = 1$ .

Using a z-table, we see that the area to the left of, or less than, this score is 0.8413. We want to know how many students scored more than this, so we subtract from 1:
1-0.8413=0.1587, which rounds to 16%.
