Answer:
1/6
Step-by-step explanation:
De la pregunta, sabemos:
30/90 del número de plantas de un cultivo de caña está contaminado.
30/90, simplificamos aún más
30/90 => 3/9 => 1/3
De estos, la mitad han sido tratados.
La fracción de los cultivos tratados son:
1/2 de 3/9 = 1/2 × 1/3
= 1/6
La fracción del número de plantas del cultivo que no ha sido tratada se calcula como:
1/3 - 1/6
El mínimo común denominador es 6
= (2 × 1) - (1 × 1) / 6
= 2 - 1/6
= 1/6
Usando proporciones, se encuentra que la fracción del número de plantas del cultivo que no ha sido tratada es [tex]\mathbf{\frac{5}{6}}[/tex]
Las plantas que no han sido tratadas son:
Las que non estan contamidas(6/9 de el total).1/2 de las contaminadas(1/2 de 3/9).Por eso, la proporción total es dada por:
[tex]\frac{6}{9} + \frac{1}{2}\frac{3}{9} = \frac{6}{9} + \frac{3}{18} = \frac{12}{18} + \frac{3}{18} = \frac{15}{18} = \frac{5}{6}[/tex]
La fracción del número de plantas del cultivo que no ha sido tratada es [tex]\mathbf{\frac{5}{6}}[/tex]

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
Write the function rule for the function shown below reflected in the given axis.
f(x)x; -axis
Let g(x) be the reflection of f(x) in the -axis. What is the function rule for g(x)?
g(x)
nothing
Answer:
The answer is "[tex]\bold{g(x) = -\frac{1}{2x} \ and \ g(x)= -3x-12}[/tex]".
Step-by-step explanation:
Please find the complete question in the attached file.
[tex]\to f(x) = 4x[/tex]
Following the y-axis reflexion, f(x) is 4(-x) = -4x after a [tex]\frac{1}{8}[/tex] vertical compression factor, f(x) is [tex]\frac{1}{8} \times -4x = \frac{1}{-2x}[/tex]
So, the [tex]g(x) = - \frac{1}{2x}[/tex]
The y axis reflecting indicates that its entire function is multiplied by -1
so, [tex]f(x)=3x+12^{-1}[/tex]
[tex]\to g(x)=-3x-12[/tex]
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.

4j=-8
j=-2
Now we plug j into j+9:
-2+9=7
So j+9 is 7

Find the integers m and n such that (m+n√2)(1-√2)²=-2+2√2
Answer:
m = n = 2
Step-by-step explanation:
(m + n√2)(1 - √2)² = -2 + 2√2
(m + n√2)(1 - 2√2 + 2) = -2 + 2√2
(m + n√2)(3 - 2√2) = -2 + 2√2
3m - 2m√2 + 3n√2 - 4n = - 2 + 2√2
(3n - 2m)√2 + 3m - 4n = 2√2 - 2
3n - 2m = 2
4n - 3m = 2
3n - 2m = 4n - 3m
n = m
4n - 3n = 2
n = 2
m = 2

Four times a number plus three times a second number is negative nine. Twice the first number plus the second number is three.
Call the first number m and the second number n.
Answer:
m=9
n=-15
Step-by-step explanation:
If you set it up in a systems of equations way, ou would have
4m+3n=-9
+ . 2m+n=3
-------------------
You would need to cancel out a variable and in my opinion, canceling m out is easier.
4m+3n=-9
+-4m-2n=-6
-------------------
0m+n=-15
n=-15
you then plug this into one of the equations, (in my opinion the 2nd one is easier)
2m-15=3
2m=18
m=9
this gives you m so you can get the answer
m=9 and n=-15

Which of the following correctly labels the population of violets Is to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
As she has 60 seeds, firstly she must number each plant in order or randomly see the height, After that he can peek at random 10 plants to test the fertilizer.
Thus, the required answer is she needs to number each plant from 1 to 60 and randomly peek at 10 of them. Option c is correct.

The perimeter of the blueprint is represented by the equation P=8x. What is the equation of the perimeter when solved for x
Answer:
x = P/8

We need to solve the above equation for x.
Dividing both sides of the equation by 8.
[tex]\dfrac{P}{8}=\dfrac{8x}{8}\\\\x=\dfrac{P}{8}[/tex]

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.

Two less than three-fourths of a number is, at most, negative seventeen. what is the range of values for the number?
Answer:
[tex]x\leq -20[/tex]
values ranging from minus infinity to negative 20
Step-by-step explanation:
we write the inequality associated with the text in terms of the unknown number "x" as:
[tex]\frac{3}{4} x-2\leq -17[/tex]
then, we solve for "x" by adding 2 to both sides, and then isolating "x" on the left as shown below:
[tex]\frac{3}{4} x-2\leq -17\\\frac{3}{4} x\leq -17+2\\\frac{3}{4} x\leq -15\\3\,x\leq -60\\x\leq -\frac{60}{3} \\x\leq -20[/tex]
then, the range of x-values is from minus infinity to negative 20

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)
