The correct option regarding the skewness of the given distribution is:
The data is clumped to the right.
How to find the skewness of the distribution?To find the skewness of the distribution, we need to look at the mean and the median of the distribution.
The mean is the sum of all the observations in the distribution divided by the number of observations. The graph shows the number of times that each observation appears, hence the mean is found as follows:
Mean = (1 x 2 + 2 x 5 + 3 x 8 + 4 x 2 + 5 x 12 + 6 x 7 + 7 x 13 + 8 x 3 + 9 x 5 + 10 x 11)/(2 + 5 + 8 + 2 + 12 + 7 + 13 + 3 + 5 + 11) = 6.12.
The median is the middle term of the distribution. There are 68 terms in the distribution, hence the median is the observation in which the count reaches 34. Then:
Observation 1: Count 2.Observation 2: Count 2 + 5 = 7.Observation 3: Count 7 + 8 = 15.Observation 4: Count 15 + 2 = 17.Observation 5: Count 17 + 12 = 29.Observation 6: Count 29 + 7 = 36 > 34.Hence the median is of 6, which is less than the mean. Since the median is less than the mean, the data is right skewed, that is, clumped to the right.

What is meant by exponent?The number of times a number is multiplied by itself is referred to as its exponent. For instance, 2 to the third (written as 23) means: 2 x 2 x 2 = 8. An exponent is a number that is superscripted over another number. In other words, it denotes that the base has been raised to a certain level of power. Other names for the exponent include index and power. If m is a positive number and n is its exponent, the expression mn denotes that m has been multiplied by itself n times. Power is defined in mathematics as a base number raised to the exponent, where the base number is the factor multiplied by itself and the exponent is the number of times the same base number is multiplied.To learn more about exponent, refer to:

What is an equation?
A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. Equations are used to describe geometric shapes in Cartesian geometry. Since the investigated equations, such as implicit equations or parametric equations, have an unlimited number of solutions, the goal has changed. Now, one utilizes equations to analyze the attributes of figures rather than explicitly providing the solutions or counting them, which is impossible. The fundamental concept of algebraic geometry, a significant branch of mathematics, is presented here. Equations involving one or more functions and their derivatives are known as differential equations. By identifying a derivative-free formulation for the function, they may be resolved. Processes involving rates are modeled using differential equations.
given equation,
f(x) = 7√(x+8) - 8
y = 7√(x+8) - 8 (replace f(x) with y)
x = 7√(y+8) - 8 (interchange x and y)

For the attached blue bird, find the quadratic equation written in vertex form
Answers
The vertex form of a quadratic equation is expressed as
y = a(x - h)^2 + k
where
h and k are the x and y x and y coordinates of the vertex of the parabola.
a is the leading coefficent
From the information on the graph,
h = 13
k = 13
By substituting these values into the formula,
y = a(x - 13)^2 + 13
On the graph, when x = 26, y = 0
Substituting these values into the equation, we have
0 = a(26 - 13)^2 + 13
0 = a * 13^2 + 13
0 = 169a + 13
169a = - 13
a = - 13/169
a = - 1/13
By substituting a = - 1/13, h = 13 and k = 13 into the verte form equation, the quadratic equation written in vertex form is
y = - 1/13(x - 13)^2 + 13

The solution of a system of two linear equations interprets the point of intersection of the two lines geometrically
When the two lines intersect each other at a point, then the system of two linear equations has a unique solution.
If two linear equations in the given system represent two lines parallel to each other, then the system becomes inconsistent and in that case, it has no solution.
If the system is dependent i.e. there is only one linear equation in two variables, then every point on the line is the solution of the equation.
So, in that case, it has infinitely many solutions.

Answers
the real solutions for the equation d² - 12 d + 4 = 6 is d = 6 ± √38.
The equation given is:
d² - 12 d + 4 = 6
Subtract 6 from both the sides:
d² - 12 d + 4 - 6 = 6 - 6
d² - 12 d - 2 = 0
solve for the real solutions:
D = b² - 4ac
D = (-12)² - 4(-2)(1)
D = 144 + 8
D = 152
d = 12 ±√152 / 2 (1)

Answers
Answer:
37.5, 75 and 67.5 degrees
Explanation:
The sum of angle in the given triangle is 180 degrees
Hence;
x + x + 30 + 2x = 180
4x + 30 = 180
4x = 180 - 30
4x = 150
x = 150/4
x = 37.5 degrees
Get angle 2x
2x = 2(37.5)
2x = 75 degrees
Get angle x + 30
x + 30 = 37.5 + 30
x = 30 = 67.5 degrees
Hence the angles of the triangle are 37.5, 75 and 67.5 degrees

Answers
26.14 ft²
1) Considering that triangular herb:
2) Let's calculate the area of that triangle using the Heron formula so that we can not need to find the height:
2.1) Calculate the Perimeter:
2P = 2+3+4
2P = 9 yd
2 yards = 6 ft
3 yd = 9ft
4 yd = 12 ft
Converting into feet
9 yards = 27 feet
And the Semi perimeter (half the perimeter):
P = 9/2
27/2
Now we can plug that into Heron's Formula:
[tex]\begin{gathered} A=\sqrt[]{p(p-a)(p-b)(p-c)} \\ A=\sqrt[]{\frac{27}{2}(\frac{27}{2}-6))(\frac{27}{2}-9)(\frac{9}{2}-12)} \\ A=\frac{27\sqrt[]{15}}{4}\approx26.14 \end{gathered}[/tex]3)

HARVEY HAS KEPT A RECORD OF ALL THE FISH HE CAUGHT IN WILLOW GROVE LAKE. HE HAS CAUGHT, 126 BASS 42 CATFISH 72 BLUE GILL WHAT IS THE EMPIRICAL PROBABILITY THAT THE NEXT FISH HE CATCHES WILL BE A CATFISH?
Answers
Given that Harvey caught:
• 126 bass.
,• 42 catfish.
,• 72 blue gill
You need to remember that, by definition, an Empirical Probability can be calculated by dividing the number of times the event occurs by the total number of trials.
In this case, you know that he caught 42 catfish. Therefore, you can identify that:
[tex]Number\text{ }of\text{ }times\text{ }the\text{ }event\text{ }occurs=42[/tex]You can also determine that:
[tex]Total\text{ }number\text{ }of\text{ }trials=126+42+72=240[/tex]Therefore, you can determine that the Empirical Probability that the next fish Harvey catches will be a catfish is:
[tex]P(E)=\frac{42}{240}=\frac{7}{40}=0.175[/tex]Hence, the answer is:
[tex]P(E)=0.175[/tex]
