Please help and tell me how to do so!

I paid $14.96 for a shirt. I got 35% off the original price. What was the original price

ELEN [110]

Hello there!

35% = $14.96
100% = x

Cross multiply

35 * x = 14.96 * 100

35x = 1496

35x/35 = 1496/35

x = 42.74

Thus,

The original price was $42.74

Let me know if you have any questions about the answer. As always, it is my pleasure to help students like you!

What is the additive inverse of the polynomial? -7y^2+x^2y-3xy-7x^

gogolik [260]

The additive inverse of the polynomial $- 7{y^2} + {x^2}y - 3xy - 7{x^2}$ is $\boxed{7{y^2} - {x^2}y + 3xy + 7{x^2}{\text{ or }} - \left( { - 7{y^2} + {x^2}y - 3xy - 7{x^2}} \right)}.$

Further explanation:

Given:

The polynomial is $- 7{x^2} + {x^2}y - 3xy - 7{x^2}.$

Explanation:

The given polynomial is $- 7{y^2} + {x^2}y - 3xy - 7{x^2}.$

The additive inverse can be defined as when we add a number to some number and get result as zero.

The value of additive inverse is same as of the number but the sign of the additive inverse is opposite.

The additive inverse of the polynomial can be expressed as follows,

$\begin{aligned}A&= - 7{y^2} + {x^2}y - 3xy - 7{x^2} + \left( {7{y^2} - {x^2} + 3xy + 7{x^2}} \right)\\&= - 7{y^2} + 7{y^2} + {x^2}y - {x^2}y - 3xy + 3xy - 7{x^2} + 7{x^2}\\&= 0\\\end{aligned}$

The additive inverse of the polynomial $- 7{y^2} + {x^2}y - 3xy - 7{x^2}$ is $\boxed{7{y^2} - {x^2}y + 3xy + 7{x^2}{\text{ or }} - \left( { - 7{y^2} + {x^2}y - 3xy - 7{x^2}} \right)}.$

The average age of online consumers a few years ago was 24.1 years. As older individuals gain confidence with the Internet, it

love history [14]

Answer:

The correct option is (C).

Step-by-step explanation:

A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.

It is a hypothesis of no difference.

It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.

Whereas the alternative hypothesis is a contradicting statement tot he null hypothesis. It is denoted by Hₐ.

In this case we need to test whether the average age of online consumers has increased or not.

From previous data we know that the average age of online consumers a few years ago was 24.1 years.

A one-sample mean test can be used to determine whether the mean age has increased or not.

The hypothesis for the test can be defined as follows:

H₀: The average age of online consumers is 24.1 years, i.e. μ = 24.1.

Hₐ: The average age of online consumers is more than 24.1 years, i.e. μ > 24.1.

Thus, the correct option is (C).

Answer:

The image is (-18,0)

Step-by-step explanation:

Here, we want to find the image of the given point after dilation by the given scale factor

Mathematically, given a point with the pre-image (x,y) going under the dilation of scale factor k, centered at the origin, the coordinates of the image will be;

(kx , ky)

Applying this in the given scenario, we have

(2(-9) , 2(0))

= (-18,0)
