b. The probability that a randomly selected home run was hit to left field is 0.031.
c. Yes it was unusual for this player to hit a home run to left field.
How to calculate the probability?From the information, the baseball player hit 63 home runs in a season. Of the 63 home runs, 18 went to right field, 25 went to right center field, 9 went to center field, 9 went to left center field, and 2 went to left field.
The probability that a randomly selected home run was hit to right field is:
= 18 / 63
= 0.286.
The probability that a randomly selected home run was hit to left field is:
= 2 / 63
= 0.031.
It was unusual for this player to hit a home run to left field as the chance is 3%.

f(-4) = -18, f(-2) = -10, f(6) = 12 and f(-1) = -6 using the piecewise function.
What are piecewise functions?A function defined by numerous sub-functions, where each sub-function applies to a distinct interval in the domain, is known in mathematics as a piecewise-defined function (also known as a piecewise function, a hybrid function, or definition by cases). Instead of being a property of the function itself, piecewise definition is a means to express the function.
When the domain may be divided into intervals on which the property holds, the phrase "property holding piecewise for a function" is used, which is separate but related. This is a characteristic of the function itself, as opposed to the idea mentioned above.
f(-4) = 4(-4)-2 = -18 ∵-4≤-1
f(-2) = 4(-2)-2= -10 ∵-2≤-1
f(6) = [tex]\frac{1}{2}*6 + 9 = 12[/tex] ∵6>-1
f(-1) = 4(-1)-2 = -6 ∵-1≤-1

The Above Contour Map Is Given For A Function F(X,Y). Use It To Estimate The Value Of The Partial Derivatives Fx(2, 1) And Fy(2, 1).
We may deduce from the contour map that the estimates of the given functions are;
fx(2, 1) = 10
fy(2, 1) = 3
What exactly does the term "counter map" mean?The geographic mapping used as a form of activism against prevailing power systems is known as counter-mapping.
How Do You Interpret Contour Lines on a Map?Contour lines are described as the faint lines drawn on a map that link places of equal height above sea level. This indicates that even if you followed a contour line physically, the elevation (height of the land) would stay constant.
According to the contour map, the contour lines indicate that the coordinate (2, 1) in the x-direction has a value of 10.
Therefore; fx(2, 1) = 10
Using the same idea, we can deduce from the attached contour map that the coordinate (2, 1) in the y-direction will have a value between 0 and 6. Therefore;
Average = (0 + 6) divided by 2 = 3
Thus; fy(2, 1) = 3

Are isosceles triangles equal to 180?
Yes, the isosceles triangles are equal to 180 degrees.
We know that isosceles triangles are triangles which have two equal sides. Since the sides are equal, they subtend equal angles as well.
However, the two equal angles subtended by the equal sides and one more angle which is subtended by the third side of the isosceles triangle all add up to a total of 180 degree as we know that the sum of all the angles of a triangle is always equal to 180 degrees.

Is the equation 3x² 11x 10 0 a quadratic equation?
Yes , the equation 3x² + 11x + 10 = 0 is a quadratic equation and the roots are x = -5/3 and x = -2
What is Quadratic Equation?
A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c = 0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
where ( b² - 4ac ) is the discriminant
when ( b² - 4ac ) is positive, we get two real solutions
when discriminant is zero we get just one real solution (both answers are the same)
when discriminant is negative we get a pair of complex solutions
Given data ,
Let the equation be represented as A
Now , the value of A is
3x² + 11x + 10 = 0 be equation (1)
Now , the equation is of the form ax² + bx + c = 0 , where the value of a = 3 , b = 11 and c = 10
So , the coefficient a is has the variable x² and equation 3x² + 11x + 10 = 0 is a quadratic equation
The roots of the quadratic equations are
x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )
Substituting the values in the equation , we get
x = [ -11 ± √ ( ( 11 )² - 4 ( 3 ) ( 10 ) ) ] / 2 ( 3 )
On simplifying the equation , we get
x = [ -11 ± √ ( 121 - 120 ) ] / 6
x = ( -11 ± 1 ) / 6
So , the two roots of the equations are
x = ( -11 - 1 ) / 6 and
x = ( -11 + 1 ) / 6
x = -2 and
x = -5/3

How do you prove SSS and SAS?
The triangles are congruent if all three sets of comparable sides are present. The side-side-side shortcut is a congruence technique (SSS).
Triangles are considered congruent by SAS if their two sides match up with their corresponding two sides on the other triangle, and if their included angles match up in both triangles.
We can prove two triangles, either by SSS or SAS by simply taking two triangles and checking whether the sides and the angles of the corresponding triangles are congruent or not.
By simply comparing it on the basis of their sides and angles we can easily prove the corresponding triangles by SSS or SAS.

What is the slope y =- 5x 3?
Parallel lines are two straight lines that never cross. For this to happen, the lines have to have the same slope.
In this case, the equation given is in what's called "slope-intersect" form. The general form of the slope intercept formula is y=mx + b where m is the slope of the line and b is the point on the Y-axis where the line crosses.
The equation given is y=5x+3 and since the 5 is in the place of m from the general equation, 5 is the slope. Since parallel lines have the same slope, 5 is the answer.
Slope-Intercept Form:
When we're given a linear equation we can immediately see if it's in the slope-intercept form if it follows the format y=mx+b. As long as y does not have a coefficient the slope and y-intercept are the values of m and b.

How do you write 6 more than a number?
“6 more than twice m” can be written in the mathematical form as 2m+6.
The question is saying that we have to write “6 more than twice m” as an algebraic expression or into a mathematical expression.
As in the question, it is mentioned that we have to take the number m as a variable.
So, we are going to use this ‘m’ for solving this question.
Let the number be m.
Then, twice of m will be similar to 2 times m or m multiplied by 2.
Therefore, twice m will be 2m.
Now, the question is saying that 6 more than twice m.
“6 more than” means 6 is added to that specific number.
Hence, 6 more than that number which is twice of m will be 2m+6.
Hence, “6 more than twice m” can be written in the mathematical form as 2m+6.
