"Choice D" The dot plot with the outlier at 4 feet and data points condensed on the right from 5.5-7 feet is the correct dot plot.
Step-by-step explanation:
ExplanationA dot plot is a statistical chart consisting of data points plotted on a simple scale, typically using filled-in circles.
A skew represents the direction in which the data points follow.
A negative skew indicates that the majority of the data points fall on the left side of the scale. Ex: "The height of the sunflowers in feet decreases when less sunlight is given."A positive skew indicates that the majority of the data points fall on the right side of the scale. Ex: "The height of the sunflowers in feet increases when more sunlight is given."An outlier is a data point that "stands out" from other data points.
Answer BreakdownChoices A and B are skewed left because their data points lie on the left side of the number line. These data points display a decrease in the sunflowers' height. So they are automatically eliminated. Choice C is skewed right, however, it contains no outliers. All the data points are condensed evenly to one side. This answer is incorrect. Choice D is the correct answer. The data points lie on the right side of the scale. There is also one outlier present at 4 feet, separating it from the rest of the data points.Please let me know if this helped!!!

Which function represents a function with zeros at -3,-1, 0, and 6?
A. y= (x-6)(x + 1)(x + 3)
B.y= x(x-3)(x - 1)(x + 6)
C. y= x(x-6)(x + 1)(x + 3)
D. y=(x-3)(x - 1)(x + 6)
Answer:
C
Step-by-step explanation:
The function is y=x(x-6)(x+3)(x+1). Therefore, option C is the correct answer.
Given that, a function with zeros at -3,-1, 0, and 6.
What are zeros of a function?The zero of a function is any replacement for the variable that will produce an answer of zero. Graphically, the real zero of a function is where the graph of the function crosses the x‐axis; that is, the real zero of a function is the x‐intercept(s) of the graph of the function.
Now, x=-3⇒x+3, x=-1⇒x+1, x=0 and x=6⇒x-6.
The function is y=x(x-6)(x+3)(x+1).
The function is y=x(x-6)(x+3)(x+1). Therefore, option C is the correct answer.

Find the value of x for which L parallel m (3x-33) (2x+26)
Answer:
59
Step-by-step explanation:
Find the diagram attached
From the diagram, we can see that both given angles are vertically opposite angles, hence they are equal
3x - 33 = 2x+26
3x-2x = 26 + 33
x = 59
Hence the value of x is 59
what is the answer to solve for n
Step-by-step explanation:
According to pythagoras theorem the square length of hypotenuse is equal to sum of other two sides
n^2 + 19^2 = 15^2
n^2 + 361 = 225 if we subtract 361 from both sides
n^2 = -136 but the root of square cannot be negative

Find the slope of tangent line at (1,-1.5)
Answer:
The slope of the tangent m = -0.0833
Step-by-step explanation:
Step(i):-
Given that the curve
x y - 2y² + x² = -5 ...(i)
Differentiating equation (i) with respective to 'x', we get
[tex]x(\frac{dy}{dx} )+y (1) -2(2y)\frac{dy}{dx} + 2x=0[/tex]
[tex]x(\frac{dy}{dx} ) -2(2y)\frac{dy}{dx} = -2x-y[/tex]
[tex](x -4y)\frac{dy}{dx} = -2x-y[/tex]
[tex]\frac{dy}{dx} = \frac{-2x-y}{x-4y}[/tex]
Step(ii):-
The slope of the tangent
[tex](\frac{dy}{dx})_{1,-1.5} = \frac{-2x-y}{x-4y}[/tex]
[tex](\frac{dy}{dx})_{1,-1.5} = \frac{-2(1)-(-1.5)}{1-4(-1.5)}[/tex]
m = [tex]\frac{-2+1.5}{1+6}[/tex]
[tex]m = \frac{-0.5}{6} = -0.083[/tex]
The slope of the tangent m = -0.0833
A girl is 6 years younger than her brother. The
product of their ages is 135. Find their ages.
=============================================================
Work Shown:
x = brother's age, which is some positive whole number
x-6 = sister's age, since she is 6 years younger than her brother
The product is the result of multiplication, so we multiply x and (x-6) to get 135
x*(x-6) = 135
x^2-6x = 135
x^2-6x-135 = 0
Use the quadratic formula to solve from here
We plug in a = 1, b = -6, c = -135
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(-6)\pm\sqrt{(-6)^2-4(1)(-135)}}{2(1)}\\\\x = \frac{6\pm\sqrt{576}}{2}\\\\x = \frac{6\pm24}{2}\\\\x = \frac{6+24}{2}\ \text{ or } \ x = \frac{6-24}{2}\\\\x = \frac{30}{2}\ \text{ or } \ x = \frac{-18}{2}\\\\x = 15\ \text{ or } \ x = -9\\\\[/tex]
x represents the brother's age, in years. So x must be positive.
Since x must be positive, this means we rule out x = -9
The value x = 15 is the only practical solution.
If x = 15, then x-6 = 15-6 = 9
The brother is 15 years old and the sister is 9 years old.
The product of their ages is 15*9 = 135, which confirms the answers.

A tank contains 1000L of pure water. Brine that contains 0.02kg of salt per liter enters the tank at a rate of 5L/min. Also, brine that contains 0.07kg of salt per liter enters the tank at a rate of 10L/min. The solution is kept thoroughly mixed and drains from the tank at a rate of 15L/min. Answer the following questions.
a. How much salt is in the tank after t minutes?
b. How much salt is in the tank after 4 hours?
Answer:
51.877 kg
Step-by-step explanation:
a
See attachment for calculations
b
The amount of salt in the tank after 4 hours is gotten by simply replacing t in the equation from a, with 4 hours. Since the t gotten in a above is in minutes, we'd convert hours to minute as well. If we do that, we have
t = 4 hours = 4 * 60 minutes = 240 minutes
y = 160/3 (1 - e^((-3 * 240)/200))
y = 160/3 (1 - e^(-720/200))
y = 160/3 (1 - 0.0273)
y = 160/3 (0.9727)
y = 51.877 kg
Therefore, the amount of salt in the tank after 4 hours is 51.877 kg

2. Findcgiven m∠A=57° and a=22
Answer:
1
Step-by-step explanation:
Answer: c = 14.287 approximately
==========================================================
Work Shown:
Refer to the diagram below. Note how side a is opposite angle A, and side c is opposite angle C.
tan(angle) = opposite/adjacent
tan(A) = a/c
tan(57) = 22/c
c*tan(57) = 22
c = 22/tan(57)
c = 14.2869670503452
c = 14.287
This value is approximate. Make sure your calculator is in degree mode
