The value of y-x is (-3)
<u>Solution:</u>
Given: The value of x-y=3
To find: The value of y-x
![\bold{x-y=3\rightarrow (1)}](https://tex.z-dn.net/?f=%5Cbold%7Bx-y%3D3%5Crightarrow%20%281%29%7D)
Let's multiply the equation (1) by (- 1) on both sides,
![\Rightarrow\bold{(x - y)\times(- 1) = 3\times(- 1)}](https://tex.z-dn.net/?f=%5CRightarrow%5Cbold%7B%28x%20-%20y%29%5Ctimes%28-%201%29%20%3D%203%5Ctimes%28-%201%29%7D)
![\Rightarrow\bold{-(x-y)=-3}](https://tex.z-dn.net/?f=%5CRightarrow%5Cbold%7B-%28x-y%29%3D-3%7D)
On multiplying the sign,
![\Rightarrow\bold{(-x+y)=-3}](https://tex.z-dn.net/?f=%5CRightarrow%5Cbold%7B%28-x%2By%29%3D-3%7D)
The above equation can also be written as,
![\Rightarrow\bold{y-x=-3\rightarrow \text{(The required equation)}}](https://tex.z-dn.net/?f=%5CRightarrow%5Cbold%7By-x%3D-3%5Crightarrow%20%5Ctext%7B%28The%20required%20equation%29%7D%7D)
<u>Multiplication of signs:</u>
![\Rightarrow( + )\times( + ) = ( + )](https://tex.z-dn.net/?f=%5CRightarrow%28%20%2B%20%29%5Ctimes%28%20%2B%20%29%20%3D%20%28%20%2B%20%29)
![\Rightarrow( + )\times( - ) = ( - )](https://tex.z-dn.net/?f=%5CRightarrow%28%20%2B%20%29%5Ctimes%28%20-%20%29%20%3D%20%28%20-%20%29)
![\Rightarrow( - )\times( + ) = ( - )](https://tex.z-dn.net/?f=%5CRightarrow%28%20-%20%29%5Ctimes%28%20%2B%20%29%20%3D%20%28%20-%20%29)
![\Rightarrow( - )\times( - ) = ( + )](https://tex.z-dn.net/?f=%5CRightarrow%28%20-%20%29%5Ctimes%28%20-%20%29%20%3D%20%28%20%2B%20%29)
In simpler terms, when we multiply two integers with the same signs, the result is always positive and when we multiply two integers with different signs, the result is always negative.
The y intercept is 5, since slope is y=mx+b. The x intercept is at -2. If you have more problems like this there is an amazing calculator that graphs equations like this for you. www.symbolab.com. Hope this helps!
Answer:
c. Skewed-right with a mean of $5.25 and a standard error of$0.28
Step-by-step explanation:
As we have given that Sales prices of baseball cards have a right-skewed distribution with a mean $5.25 and a standard deviation is $2.80.
Now, We know that if standard deviation = σ
then, standard error = ![\frac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
As, we have standard deviation = $2.80
then standard error will be
⇒ Standard error = $0.28
Hence, Option (c) is the correct option.
In this situation, you would use division because when you divide the number of blankets by the number of boxes, you will get how many blankets were put into each kennel. And since there were 1,110 puppy blankets and 27 boxes, divide 1,110 by 27. This will get you the answer 41. This means that there are 41 puppy blankets in each box, and so the answer is D. 41.
Answer:
64.81
Step-by-step explanation:
x + .08x = 875
1.08x = 875
x = 810.19 (price of tv)
