Answer:

its B

Step-by-step explanation:

Fertilizer B is likely more effective than Fertilizer A.

The correct answer is option C: Fertilizer B will outperform Fertilizer A every time.

In mathematics and statistics, the term "mean" refers to the average of a set of variables. There are various ways to determine the mean, including geometric means, harmonic means, and simple arithmetic means (putting the numbers together and dividing the result by the quantity of observations).

To draw a conclusion from the experiment, we need to analyze the data. We can calculate the mean heights of the seedlings for each fertilizer.

For Fertilizer A: (19.8+25.7+29.0+23.2+27.8+31.1+26.5+24.7+21.3+25.6)/10 = 25.67

For Fertilizer B: (23.4+30.1+28.5+26.3+32.0+29.6+26.8+25.2+27.5+30.8)/10 = 28.89

Based on the data, it appears that the seedlings treated with Fertilizer B had, on average, a greater height than those treated with Fertilizer A.

Therefore, we can conclude that Fertilizer B is likely more effective than Fertilizer A.

The correct answer is option C: Fertilizer B will outperform Fertilizer A every time.

Answer:

  when (0, 0) is on the boundary line

Step-by-step explanation:

Any test point you use to determine shading must not lie on the boundary line. You need a test point that will make the inequality true or false. That is, it must give a result a > b or a ≥ b, where a ≠ b. A point on the boundary line will give a = b, so is not helpful.

If the test point gives "true", then it lies in the shaded area. If it gives "false," then the other side of the line is shaded.

(0, 0) cannot be used as a test point when it lies on the boundary line.

Answer:

  neither

Step-by-step explanation:

Solving the first equation for y gives you ...

  y = 1/2x -2

The slope of each line is the coefficient of x, 1/2 or 2. The slopes of 1/2 and 2 are not equal and are not opposite reciprocals. The lines are neither parallel nor perpendicular.

Answer:

the bottom right

Step-by-step explanation:

The graph of the expression is attached

To graph the inequality y ≤ -2/3x + 6, you can start by graphing the line y = -2/3x + 6, which is the equation without the inequality sign.

To do this, you can start by finding two points that lie on the line. Let's choose x = 0 and x = 3 to make it easier.

When x = 0, y = -2/3(0) + 6 = 6. So one point on the line is (0, 6).

When x = 3, y = -2/3(3) + 6 = 4. So another point on the line is (3, 4).

Plot these two points on the coordinate plane and draw a straight line through them. This line represents the equation y = -2/3x + 6.

Now, to graph the inequality y ≤ -2/3x + 6, you need to determine which side of the line satisfies the inequality. Since y is less than or equal to -2/3x + 6, you shade the region below the line.

To indicate this on the graph, you can shade the area below the line or draw a dashed line to represent the boundary of the inequality.

Answer:

9.1636

Step-by-step explanation:

1/8=1/63+1/q

1/8-1/63=1/q

63-8/504=1/q

55/504=1/q

55q=504

q=504/55

q=9.1636

So the answer is 9.1636

Answer:

x = 12.5

Step-by-step explanation:

The correct question can be found in the attachment

300x + 500/7y = 10,000

Find x if y = 87.5

Substitute y = 87.5 into the equation

300x + 500/7(87.5) = 10,000

300x + 43,750/7 = 10,000

300x + 6,250 = 10,000

Subtract 6,250 from both sides

300x + 6,250 - 6,250 = 10,000 - 6,250

300x = 3,750

Divide both sides by 300

x = 3,750/300

= 12.5

x = 12.5 when y = 87.5

System of Equations

We are required to solve the system of equations by elimination:

[tex]\left\{\begin{matrix}-2x+2y+3z=0\qquad [1]\\-2x-y+z=-3 \qquad [2]\\2x+3y+3z=5 \qquad [3]\end{matrix}\right[/tex]

Adding [1] and [3], and subtracting [1] and [2]:

[tex]\left\{\begin{matrix}5y+6z=5\qquad [4]\\3y+2z=3\qquad [5] \end{matrix}\right.[/tex]

Multiplying [5] by -3 and adding to [4]:

[tex]-4y=-4[/tex]

Solving:

[tex]y = -4 / (-4) = 1[/tex]

[tex]y=1[/tex]

Substituting into [5]:

[tex]5(1)+6z=5[/tex]

Simplifying:

[tex]6z = 0[/tex]

z=0

Substituting into [3]

[tex]2x+3(1)+3(0)=5[/tex]

Operating:

[tex]2x+3=5[/tex]

[tex]2x = 2[/tex]

[tex]x = 2/2=1[/tex]

x=1

The solution is

x=1, y=1, z=0

Answer:

x= 50°

w= 130°

y°= 110°

z°=30°

Step-by-step explanation:

x°= 180° - 60°- 70° ( angle sum of triangle)

= 50°

w°= 180° - 50° ( adjacent angles on a straight line)

= 130°

y°= 180° - 70° ( adjacent angles on a straight line)

= 110°

z°= 180 - 40° - 110° ( angle sum of triangle)

= 30°

35 more Video Games

Step-by-step explanation:

He has 3 shelves that can hold 40 video games. So thats 3 x 40 = 120. The number 120 represents the total amount of video games that he can hold. But he already has 85. So subtract 85 from 120. Thats 120 - 85 = 35. He still has room for 35 video games. Hope this helps !!
