Sal purchased two types of plant fertilizer and conducted an experiment to see which fertilizer would be best to use in his greenhouse. He planted 20 seedlings and used Fertilizer A on ten of them and Fertilizer B on the other ten. He measured the height of each plant after two weeks. What conclusion can Sal make about the plant fertilizers?

A.
No conclusion can be made because the experiment is biased.
B.
The range of heights for plants with Fertilizer B is less than Fertilizer A.
C.
Fertilizer B will outperform Fertilizer A every time.
D.
On average Fertilizer A produces a taller plant.
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.
What is the mean?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.

Booker owns 85 video games. He has 3 shelves to put the games on. Each shelve can hold 40 video games. How many more video games does he have room for?
Answer:
A
Step-by-step explanation:
i just dd t
Answer:
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 !!

300x + 300 x plus StartFraction 500 over 7 EndFraction left-parenthesis 87.5 right-parenthesis equals 10,000.y = 10000
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
Could anyone help me find the missing value of W,X,Z, and Y ?
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°
Are the lines X - 2Y= 4 and Y = 2X -2 parallel perpendicular or neither?
9514 1404 393
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.
A coffee distributor plans to mix some Rift Valley coffee that normally sells for $12.10 per pound with some Mexican Shade Grown coffee that normally sells for $13.10 per pound to create 50 pounds of a new coffee blend that can sell for $12.62 per pound. How many pounds of each kind of coffee should they mix? Answer: pounds of Rift Valley coffee? pounds of Mexican Shade Grown coffee? Round your answers to the nearest whole number of pounds.
Answer:
24 pounds of Rift Valley coffee
26 pounds of Mexican Shade Grown coffee
Step-by-step explanation:
If R is pounds of Rift Valley coffee, and M is pounds of Mexican Shade Grown coffee, then:
R + M = 50
12.10 R + 13.10 M = 12.62 (50)
Substitute:
12.10 R + 13.10 (50 − R) = 12.62 (50)
12.10 R + 655 − 13.10 R = 631
R = 24
M = 26

Sarah visits an amusement park with an admissions cost of $24. Each ride costs $3. She does not buy any food or drink while she is there. If y represents the total she spends at the park and she takes x rides, which of the following is a function that represents her total spending?
A. y=24x+3
B. x+y=27
C. y=3x+24
D. y=27x
Answer:
Option C. y=3x+24 is the correct answer
Step-by-step explanation:
Using the given information,
Number of rides = x
Total cost = y
Admission cost = $24
The admission cost is a one-time cost that will remain constant while each ride costs 3 dollar so for x rides the cost will be 3x.
The total cost, if she buys no food or drink will be: 24+3x
Now we know that total cost is equal to y then
y = 24+3x
OR
y = 3x+24
Hence,
Option C. y=3x+24 is the correct answer
solve the system by elimination. need work to be shown
Answer:
x=1, y=1, z=0
Step-by-step explanation:
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

When graphing a linear inequality, when can you NOT use (0, 0) as a test point to determine which side of a boundary line to shade?
9514 1404 393
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.
