A number is even if it ends with an even digit, so 8 must be the last one.

Now, the digits to the left are more worth than those on the right, so if you want a big number you have to stack the greatest digits to the left, otherwise if you want a small number you have to stack the smallest digits to the left.

So, the greatest number is 7538, the smaller is 3578.

David is looking for the best deal on a laptop that regularly costs $719. Help him compare the price of the laptop at a

NemiM [27]

Answer:

A) $287.60.

B) $323.55.

C) David would pay more for the laptop at the store.

Step-by-step explanation:

A) Given that the store's website is offering the laptop at a 60% discount off the regular price of $ 719, ignoring tax and shipping, the sale price is obtained through the following calculation:

100 - 60 = 40

719 x 0.40 = X

287.6 = X

Therefore, in this case the sale price would be $ 287.6.

B) Since the store is having a sale, offering a 50% discount off the regular price of the laptop, and David also has an in-store-only coupon for an additional 10% off the sale price, ignoring tax, the price of sale is obtained through the following calculation:

(719 x 0.5) x 0.9 = X

359.5 x 0.9 = X

323.55 = X

Thus, the sale price in the present case would be $ 323.55.

The Store's wholesale price of a t-shirt is $50. If the markup set by the store is 30%. Calculate the retail price set by the st

yan [13]

Answer:

$65.

Step-by-step explanation:

Given:

The Store's wholesale price of a t-shirt is $50

The markup set by the store is 30%.

To find:

Calculate the retail price set by the store on the t-shirt.

Solution:

Wholesale price of a t-shirt = $50

Markup % = 30

<em>First of all we will find the markup value with the help of markup percentage and then we will simply add the wholesale price and markup value of T-shirt</em>.

Markup value of T-shirt = $30\%\ 0f\ 50=\frac{30}{100} \times50=\frac{1500}{100} =\$15$

Retail price of T-shirt = Wholesale price of a t-shirt + Markup value of T-shirt

Retail price of T-shirt = $50 + $15

Retail price of T-shirt = $65

Therefore, the retail price set by the store on the t-shirt is $65.

A sociologist recorded the estimated life expectancies of women born in Center City. Use the data from women born in 1970 and 20

Veronika [31]

$Y=0.213x-352$ will represent this linear model shown in the data table.

<h3>What will be the linear model for the given data?</h3>

Put the values of the x in the all given equations and then check the value of y if the value of y matches the given values in the option

So if we put the value x=1980 in the $Y=0.213x-352$ then

$Y=0.213(1980)-352$

$Y=69.74$

These values are closest to 70.1 whereas other options do not satisfy the condition.

Thus $Y=0.213x-352$ will represent this linear model shown in the data table.

Which function is undefined for x = 0? y=3√x-2 y=√x-2 y=3√x+2 y=√x=2

Mkey [24]

For this case, we have to:

By definition, we know:

The domain of $f (x) = \sqrt [3] {x}$ is given by all real numbers.

Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. In the same way, its domain will be given by the real numbers, independently of the sign of the term inside the root. Thus, it will always be defined.

So, we have:

$y = \sqrt [3] {x-2}$ with $x = 0$ : $y = \sqrt [3] {- 2}$ is defined.

$y = \sqrt [3] {x+2}$ with $x = 0:\ y = \sqrt [3] {2}$ is also defined.

$f (x) = \sqrt {x}$ has a domain from 0 to ∞.

Adding or removing numbers to the variable within the root implies a translation of the function vertically or horizontally. For it to be defined, the term within the root must be positive.

Thus, we observe that:

$y = \sqrt {x-2}$ is not defined, the term inside the root is negative when $x = 0$ .

While $y = \sqrt {x+2}$ if it is defined for $x = 0$ .

Answer:

$y = \sqrt {x-2}$

Option b
