Answer:

4. A cluster tells you where there is a concentration of data values.

Step-by-step explanation:

makes the most sense

A cluster tells you where there is a concentration of data values. The correct answer would be an option (C).

The variables in the scatter plot made from the data are described by the independent variable, time, which is graphed along the horizontal axis.

A cluster on a scatter plot refers to a group of points that are closely located together. This indicates that there is a concentration of data values in that area of the plot, as opposed to being spread out evenly. This cluster can be seen visually as a group of points that are tightly packed together.

Thus, a cluster tells you where there is a concentration of data values.

Hence, the correct answer would be option (C).

Answer:

x=4y/5-2

Step-by-step explanation:

Add 4y to both sides.

−5x=10+4y

The equation is in standard form.

−5x=4y+10

Divide both sides by −5.

−5

−5x

​

=

−5

4y+10

​

Dividing by −5 undoes the multiplication by −5.

x= −5

4y+10

Divide 10+4y by −5.

x=− 5/4y

​

−2

The required intercepts of the given equation is x = -2 and y = -2.5.

Distance from the origin to points where a line crosses an axis is known as the x-intercept and the y-intercept, respectively.

Here,
Given the equation of the line,
-5x-4y=10

Now, in order to determine the intercepts of the equation put x = 0 and y = 0 individually,

So,
x = 0
-4y = 10
y = -2.5

Now, put y = 0
-5x = 10
x = -2

Thus, the required intercepts of the given equation is x = -2 and y = -2.5.

Answer:

9 bags

Step-by-step explanation:

Weight each bag should be = 3/4 pound (0.75 pound)

Total weight of sunflower seeds available = 6.5 pounds

Number of packages made = 6.5/ 3/4

                                              = 8.66666666667

                                              = So 9 bags at the most

If you write 8, then  you wouldn't  be able to fit the other 0.5 pound and if you put 9, well you will have enough more space to put 6.5 pounds.

Answer:51.14

Step-by-step explanation:since its an isosceles triangle all interior angles are gonna be equal the exterior angle plus interior angle is will be kept equal to 360

2x+5+5x-3=360

7x+2=360

7x=358

x=51.14

The measure of each angle is 31, 31 and vertex angle is 118.

If a triangle side is created, the outside angle that results is equal to the product of the two opposite internal angles.

Given:

Base angle = (2x+ 5) and Vertex = (5x- 3)

So, We know that the exterior angle is equal to sum of opposite interior angle

5x- 3 = 2x+ 5 + 2x + 5

5x - 3= 4x + 10

x= 13

Thus, Each angle measure 2(13)+ 5 = 31 and

third angle = 180 - (5x- 3) = 180- 62 = 118

Hence, the measure of each angle is 31, 31 and vertex angle is 118.

Answer:

-1 + [tex]\frac{x}{7}[/tex]

Step-by-step explanation:

( 2/7x-6 ) - ( 1/7x - 5 )

First you should combine 2/7 and x, and 1/7 and x. You do this by "bringing the x up". This is how the expression looks now: (2x/7 - 6) - (x/7 - 5). Notice: when you have 1x you can just remove the 1 since it is implied. The next step is to apply the distributive property. The number we are distributing is -1 to (x/7 - 5). This is how the expression now looks like: (2x/7 - 6) - x/7 + 5. Notice: since 5 was already negative, when we multiplied it by a negative, it became positive. Now we can remove the parenthesis since they are no longer necessary: 2x/7 - 6 - x/7 + 5. The next step is to combine the fractions since they have the same denominator. This is how the expression will look like now: -6 + 5 + [tex]\frac{2x - x}{7}[/tex]. Now we should subtract x from 2x (remember x really just means 1x). This is what we have so far: -6 + 5 + x/7. Lastly, we should add 5 to -6. This is how the finished expression should look like: -1 + x/7.

Answer:

No she will not save enough money for her trip and she needs $122 more for her trip.

Step-by-step explanation:

Deborah requires $74 each day for 13 days trip

Total least amount needed for the trip = 74*13

                                                       = $962

Deborah's saving strategy : she saves $84 per month for 10 months

saved amount at the end of the 10th month = 84*10 = $840

840/10 = $84

This clearly shows she is not saving enough money for her trip. She needs $122 more to support the expense of her trip.

Timothy way

84*10= $840 is to be compared with 74*18 = $1332

This method is also not a feasible one for calculating Deborah's expenses of her trip.

Answer:

9c - 3d

Step-by-step explanation:

5c-6d+4c+3d

Gather the like terms,

5c + 4c - 6d + 3d

9c - 3d

Hope it helps!<3

Simplifying

5c + -6d + 4c + 3d = 0

Reorder the terms:

5c + 4c + -6d + 3d = 0

Combine like terms: 5c + 4c = 9c

9c + -6d + 3d = 0

Combine like terms: -6d + 3d = -3d

9c + -3d = 0

Solving

9c + -3d = 0

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '3d' to each side of the equation.

9c + -3d + 3d = 0 + 3d

Combine like terms: -3d + 3d = 0

9c + 0 = 0 + 3d

9c = 0 + 3d

Remove the zero:

9c = 3d

Your answer: 9c=3d
