Answer:
a₇ = 192
Step-by-step explanation:
There is a common ratio r between consecutive terms in the sequence.
r = 6 ÷ 3 = 12 ÷ 6 = 2
This indicates the sequence is geometric with n th term
[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]
where a₁ is the first term and r the common ratio
Here a₁ = 3 and r = 2 , thus
a₇ = 3 × [tex]2^{6}[/tex] = 3 × 64 = 192
Pls help thanks :)
Graph y ≤ - 2/3x + 6
Answer:
the bottom right
Step-by-step explanation:
The graph of the expression is attached
How to graph the expressionTo 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.

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°

Answer:
My guess:
A. Consistent independent
B. Consistent dependent
C. Inconsistent
Step-by-step explanation:
The first is a repeated equation, so it is a consistent independent equation.
The second is consistent, trying to solve the value of Y. But it looks like it needs the other equation to complete it and solve the value of Y.
The third has no pattern, and isn't trying to solve any values, unlike the others. So it is inconsistent.
(Just a quick note, I do not have experience with this, but it is my best guess)
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.

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.

Answer:

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
Answer the question, considering an event to be "unusual" if its probability is less than or equal to 0.05. If you drew one card from a standard deck, would it be "unusual" to draw a 6?
Answer:
No it's not unusual
Step-by-step explanation:
That's an unusual definition for unusual if you don't mind me saying so.
There are 4 sixes in a standard deck of cards without the jokers. There are 52 cards in that deck
4/52 = 0.077
This is greater than 0.05 so it is not unusual.
Let's add the 2 jokers and see what happens.
4/54 = 0.074
That's still not going to get the situation defined as unusual.

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

State the number of complex roots and the possible number of real and imaginary roots for each equation. The find all roots? If possible.
Answer:
x =2
x = -2
Step-by-step explanation:
(x - 2)(x + 2)(x^2 + 4) = 0
(x - 2) = 0
x = 0 + 2
x = 2
(x + 2) = 0
x = - 2
x = - 2
(x^2 + 4) = 0
x^2 = 4
x = [tex]\sqrt{4}[/tex]
x = 2
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.
