One patterned blue fabric sells for $15.00 every two yards, and another sells for $37.50 every 5 yards. Do these fabrics have th
Svetradugi [14.3K]
All we need to do is to find out how much is worth one yard in both fabrics, so we divide $15.00 by 2 and $37.50 by 5:

$15.00 ÷ 2 = $7.50 per yard
$37.50 ÷ 5 = $7.50 per yard

As both prices per yard are the same, the answer is: <u>Yes, these fabrics have the same unit cost.</u>

Plz fast plzzzzzzzz ​
scoray [572]

Step-by-step explanation:

cubing both sides (p+1)^3= (7)^3

=> p^3+1/p^3+ 3(p+1/p) = 343

=> p^3+ 1/p^3 + 3(7)= 343

=> p^3+1/p^3= 343-21

=> p^3+1/p^3= 322

hope it helps

Does the point (-4, 2) lie inside or outside or on the circle x^2 + y^2 = 25?​<br>​
Lostsunrise [7]

Given equation of the Circle is ,

\sf\implies x^2 + y^2 = 25

And we need to tell that whether the point (-4,2) lies inside or outside the circle. On converting the equation into Standard form and determinimg the centre of the circle as ,

\sf\implies (x-0)^2 +( y-0)^2 = 5 ^2

Here we can say that ,

• Radius = 5 units

• Centre = (0,0)

Finding distance between the two points :-

\sf\implies Distance = \sqrt{ (0+4)^2+(2-0)^2} \\\\\sf\implies Distance = \sqrt{ 16 + 4 } \\\\\sf\implies Distance =\sqrt{20}\\\\\sf\implies\red{ Distance = 4.47 }

Here we can see that the distance of point from centre is less than the radius.

Hence the point lies within the circle .

What is the additive version of the complex number -8+3i
Lana71 [14]

Answer:

8-3i

Step-by-step explanation:

The complex additive inverse is the number we need to add so that we get zero.  It is the negative of the number.

a + bi is –(a + bi) = –a – bi.

a+bi + (-a+-bi) = a-a + bi-bi = 0

The complex additive invers of -8+3i is

-(-8+3i)

Distribute the negative

8 -3i

If a group of independent variables are not significant individually but are significant as a group at a specified level of sign
ycow [4]

Answer:

D) collinearity

Step-by-step explanation:

Collinearity occurs when a few of the independent variables are related or match up. Collinearity increases the large proportion the variance of an estimated regression coefficient which leads to certain regression coefficient having wrong signs. It is used to explain the relationship between two variables.
