Answer:

The trend line for scatterplot A will have a negative slope, and the trend line for scatterplot B will have a positive slope.

Step-by-step explanation:

The data in scatterplot A has a general decreasing trend. This is because as x increases, the values of y tend to decrease. This means the trend line will have a negative slope.

The data in scatterplot B has a general increasing trend. This is because as x increases, the values of y tend to increase. This means the trend line will have a positive slope.

Answer:

Second option is the correct answer

$(x+11)^2+(y+6)^2 = 324$

Step-by-step explanation:

$x^{2} +12y+22x+y^2-167=0\\x^{2}+22x +y^2 +12y-167=0\\(x^{2}+22x +121)-121 +(y^2 +12y+36)-36-167=0\\(x+11)^2+(y+6)^2-324 = 0\\\huge\red{\boxed{(x+11)^2+(y+6)^2 = 324}}\\$

"During the tryouts for a university pep band, there were 4 trumpet players, 12 drummers, and 7 saxophonists. How many ways can

sladkih [1.3K]

The ways can the jazz band be selected so there are 2 trumpet players, 5 drummers, and 3 saxophonists is given below .

Step-by-step explanation:

Let's first do the math with only the trumpet,drummer and saxophonists player.

There are 4 Trumpet Player. There are 4 choices of trumpet players. Which means for each drummer, there are 4 groups of musicians:

T 1 D1S1

T 1 D2S2

and so on

So if there are 4 groups of musicians for each Trumpet ,12 drummer and there are 7 saxophonists , we get 12 groups.

It would be the product of

4T2, 12D5 and 7S3

That is 6*792*35=166,320

The amount of fabric in inches Felicia need to make the actual shape for the comforter is 660 in²

<h3>What is a trapezoid?</h3>

It is defined as the quadrilateral having four sides in which two sides are parallel to each other, it is a 2-dimensional geometry.

We have a trapezoid in the picture shown with dimensions.

We know the area of the trapezoid is given by:

$\rm A = \dfrac{a+b}{2} \times h$

Here a = 15 cm, b = 22 cm and h = 11 cm

$\rm A = \dfrac{15+22}{2} \times 11$

A = 203.5 square cm

To make the square from the trapezoid, Felicia needs to cut two triangles from the both end, as shown in the figure.

The height of the triangle = 11 cm

And base length = (22-15)/2 = 3.5 cm

The area of the triangle = (11×3.5)/2 = 19.25 square cm

Area of the two triangles = 2×19.25 = 38.5 square cm

Now the amount of fabric = 203.5 - 38.5 = 165 square cm

As the scale is given 1 cm = 2 in

1 cm ² = 4 in²

So, the amount of fabric in inches = 165×4 = 660 in²

Thus, the amount of fabric in inches Felicia need to make the actual shape for the comforter is 660 in²
