If there is a discount of 40% on an article costing #7000, then the price after discount is ​
sergejj [24]

Answer:

<h3>The answer is # 4200</h3>

Step-by-step explanation:

A discount of 40% was allowed on the price

To find the price after the discount first calculate the discount and subtract it from the original price

That's

\frac{40}{100}  \times 7000

= 2800

So the price after the discount is

#7000 - #2800

Which is

<h3># 4200</h3>

The sum of a number times 7 and 21 is at least 29. Write as an inequality
PtichkaEL [24]

The inequality is 7x + 21 \leq 29

Step-by-step explanation:

<u>DATA:</u>

Let the number be x

Number times 7 = 7*x

Sum of a number times 7 and 21 = 7x + 21

Is at least 29

<u>INEQUALITY:</u>

7x + 21 \leq 29

<u>SOLVE:</u>

7x \leq 29-21

7x \leq 8

x \leq \frac{8}{7}

Therefore, the inequality is 7x + 21 \leq 29

Find the sample standard deviation. round to the nearest tenth. 15 42 53 7 9 12 14 28 47
weqwewe [10]
<span>Because the question asks for the sample standard deviation, use this formula: s = square root of (sum of x - xBar)² / (n - 1) There are 9 numbers, there, so n - 1 = 8 Next, find the mean (xBar): 15 + 42 + 53 + . . . + 47 = 227. 227 / 9 = ~25.2 Next, for each number, subtract xBar and square the result, like this: (15 - 25.2)² = 104.0 (42 - 25.2)² = 282.2 (53 - 25.2)² = 772.8 ... Next, add up all those values (i.e., 104 + 282.2 + 772.8...) and divide by (n - 1). In this example, the answer to this is 2,535.2 / 8, or 316.9. Finally, take the square root of that number to get s. sqrt (316.9) = 17.8. Therefore, the answer is 17.8.</span>
