Answer:

Before discount = $61.25

After discount = $49.00

Step-by-step explanation:

Given information:

Discount = $12.25
Coupon = 20%

The price of the gift before the discount is 100%.

If the $12.25 discount was 20% of the purchase price, then:

⇒ original price (before discount) = (12.25 / 20) × 100 = $61.25

To find the price after the discount, simply subtract the discount from the found original price:

⇒ $61.25 - $12.25 = $49.00

Conclusion

Before discount price = $61.25
After discount price = $49.00

A common size for floor tiles is 1 square foot in area. how many square inches (in2) are in a square foot (ft2)?

Komok [63]

There are 144 square inches in a square foot.

Explanation

A common size for floor tiles is 1 square foot in area.

We know that, 1 foot = 12 inches.

So, 1 square foot = (1 foot × 1 foot) = (12 inches × 12 inches ) = 144 square inches.

So, there are 144 square inches in a square foot.

Response Question

Paha777 [63]

Answer:

The right solution is "3.29, 3.57".

Step-by-step explanation:

Seems that the given problem is incomplete. Below is the attachment of the complete and appropriate query.

The given values are:

Randomly selected adults,

$n = 105$

Mean,

$\bar{x} = 3.42$

Standard deviation,

$s = 0.75$

Now,

At 95% confidence level if given by,

= $\bar{x} \ \pm \ Z_{\frac{\alpha}{2} }\times \frac{s}{\sqrt{n} }$

On putting the given values, we get

= $3.42 \ \pm \ Z_{\frac{0.05}{2} }\times \frac{0.75}{\sqrt{105} }$

= $3.42 \ \pm \ 1.96\times 0.073$

= $3.42 \ \pm \ 0.143$

= $3.29, 3.57$

<h3>Answer: 318</h3>

===============================================

Explanation:

Refer to the diagram below. Notice how I've formed 3 rectangles underneath the curve. The term "right Riemann sum" refers to the idea of making each rectangle's upper right corner be on the curve. The upper left corner spills over top, meaning we have an over-estimate going on here.

Simply find the area of each rectangle, and then add up those sub areas. That will get you to the final answer.

Note how we go from x = -1 to x = 5, which is a distance of 5-(-1) = 6 units. Split three ways and each interval is 6/3 = 2 units wide.

If we started at x = -1, then increasing 2 units leads us to x = -1+2 = 1 as the first x input we compute into f(x). This is the height of the first rectangle.

Then 1+2 = 3 is the next input, meaning f(3) is the height of the next rectangle, and so on. We keep going until all rectangles are accounted for.

----------------------

You should have these rectangle heights:

when moving from left to right.

They add up to 3+29+127 = 159. Double that to get to the final answer of 2*159 = 318

The formula I'm using is

$\Delta x*(f(x_1) + f(x_2) + \dots f(x_n))$

where x1,x2,... represents the values 1, 3, and 5. These are the x values plugged into the function to get the corresponding heights (3, 29, 127)
