Answer:
Step-by-step explanation:
Thandi's statement that 20% of Alaskan totem poles featured in the book have eagles carved in them is not accurate.
A two-way table, also known as a contingency table, is used to organize and display the relationship between two categorical variables. The table shows the frequency or count of observations for each combination of the two variables. In this case, the two variables are the animals carved in the totem poles and the regions where the totem poles are located.
To find the percentage of Alaskan totem poles that have eagles carved in them, we need to divide the number of Alaskan totem poles with eagles by the total number of Alaskan totem poles and multiply by 100. This can be calculated as:
(Number of Alaskan totem poles with eagles / Total number of Alaskan totem poles) * 100
Without the data for the two-way table it's impossible to check if the statement is correct or not. It's important to note that without the data it is also impossible to know the context of the statement and the information provided in the book.
Answer:
=Have Eagles
=50%
Step-by-step explanation:
Thandi may have found the percent of the total totem poles that have eagles. The actual percent of Alaskan totem poles that have eagles carved in them is 50%.

Answer:
[tex]\textsf{A)} \quad 5+3\sqrt{2}[/tex]
Step-by-step explanation:
Given rational expression:
[tex]\dfrac{4+\sqrt{2}}{2 -\sqrt{2}}[/tex]
To rationalise the denominator, multiply both the numerator and denominator by the conjugate of the denominator.
The conjugate of an expression is where we change the sign in the middle of the two terms. Therefore, the conjugate of the denominator of the given expression is:
[tex]2 + \sqrt{2}[/tex]Multiply the numerator and denominator by the conjugate of the denominator:
[tex]\implies \dfrac{4+\sqrt{2}}{2 -\sqrt{2}} \cdot \dfrac{2 +\sqrt{2}}{2 +\sqrt{2}}[/tex]
Simplify:
[tex]\implies \dfrac{(4+\sqrt{2})(2 +\sqrt{2})}{(2 -\sqrt{2})(2 +\sqrt{2})}[/tex]
[tex]\implies \dfrac{8+4\sqrt{2}+2\sqrt{2}+\sqrt{2}\sqrt{2}}{4+2\sqrt{2}-2\sqrt{2}-\sqrt{2}\sqrt{2}}[/tex]
[tex]\implies \dfrac{8+6\sqrt{2}+2}{4-2}[/tex]
[tex]\implies \dfrac{10+6\sqrt{2}}{2}[/tex]
Reduce to its simplest form by dividing the numerator and the denominator by 2:
[tex]\implies 5+3\sqrt{2}[/tex]

Graph the function m(x) = x + 1
When the function, m ( x) = x + 1 is graphed, the result is shown attached.
How to graph a function ?When graphing a function, you need to remember that x is the independent variable. This means that you need to come up with the values of x and then use these values to come up with the corresponding values of y or m (x ) using the function.
Assuming you have values of x which are -3, -2, -1, 0, 1, 2, 3, the values of y would be:
x = - 3:
= x + 1
= - 3 + 1
= -2
x = - 2
= - 2 + 1
= - 1
x = - 1
= - 1 + 1
= 0
x = 0:
= 0 + 1
= 1
x = 1 :
= 1 + 1
= 2
x = 2 :
= 2 + 1
= 3
x = 3 :
= 3 + 1
= 4
The points would then be:
( - 3, - 2) , ( - 2, - 1) , ( - 1 , 0 ) ( 0, 1 ) ( 1, 2 ) ( 2, 3 ) ( 3, 4 )
The graph would be shown as attached.

Let A= {a,b,c,d,e,f } and let B= {1,2,3,} determine n(AxB)
The value of n(AxB) is mathematically given as
n(A x B) = 18
What is the magnitude of the sample?Generally, It is possible to extend the formula for calculating the magnitude of a vector to any number of dimensions. For instance, the magnitude of a four-dimensional vector denoted by
a=(a1,a2,a3,a4) may be calculated using the following formula: a=a21+a22+a23+a24.
The question "how much of a quantity" is what's meant to be answered when one asks about magnitude.
For instance, the magnitude may be used to provide an explanation for why the speeds of a vehicle and a bicycle cannot be compared directly to one another. It is also possible to use it to describe the distance traveled by an item or the quantity of an object in terms of its magnitude. Both of these applications need the usage of magnitude.
n(A x B) = |A| x |B|
= 6 x 3
n(A x B) = 18
Where
|A| is the number of elements in set A (in this case, 6) and |B| is the number of elements in set B (in this case, 3).The product of these two values is the total number of ordered pairs that can be formed from the elements of A and B, which is 18.

What’s Ln(d)=n in exponential form?
Answer:
ln(d) = n can be rewritten in exponential form as d = e^n.
Step-by-step explanation:
The natural logarithm, denoted by ln, is the logarithm to the base e (approximately 2.718). The inverse of the natural logarithm function is the exponential function e^x. Therefore, when you take the natural logarithm of a number, you can raise e to the power of that number to get the original value.
ln(d) = n is the same as d = e^n
So, Ln(d)=n can be written as d = e^n
This is because e^n is the inverse function of Ln(d) and Ln(d)=n is the logarithm form of d = e^n

Let f(x)=−|x−4|+4 and g(x)=1/2x−4. Graph the functions in the same coordinate plane. What are the solutions to f(x)=g(x)? Enter your answers in the boxes from smallest to largest.
x =
and x =
Answer:
Step-by-step explanation:
To find the solutions to f(x) = g(x), we need to find the values of x that make the two sides of the equation equal.The function f(x) = −|x−4| + 4 is a piecewise function. For x≤4, f(x) = −(x−4) + 4 = 4−x and for x>4, f(x) = (x−4) + 4 = x.The function g(x) = 1/2x − 4 is a linear function.When we graph these two functions in the same coordinate plane, we can see that they intersect at the point (4, 4) this point is the only solution where f(x) = g(x)so the solution of x = 4

number of tickets for adult = 170 and number of tickets for children = 151
What is equation with two variables?
The equation that has two unknown variables and express the equality between two or more expression is called equation with two variables.
How many tickets for adult and kids?
let, x denotes the number of adults went to theater.
y denotes the number of children went to theater
price of ticket for each adult = $3.50
price of tickets for each child = $2.50
if the number of total tickets = 321
x + y = 321
total cost of tickets = $3.50x + $2.50y = 972.21 dollar
we will solve the above two equations, y = 321 - x
by putting the y value in the second equation,
3.50x + 2.50 (321- x) = 972.21
3.50x + 802.5 - 2.50x = 972.21
x = 169.71
number of adults went to theater = 170
from, y = 321 -169.71
y = 321 - 169.71
y = 151.3, y= 151
number of children went to theater = 151

Find the coordinates of the intersection of the diagonals of the parallelogram with the vertices
W(-2,5), X(2, 5), Y(4, 0), and Z(0, 0).
The coordinates of the intersection are ( , )
Step-by-step explanation:
the intersection of the diagonals of a parallelogram is always the middle point of either of the diagonals.
so, all we need to do is identify a diagonal and find is middle point.
a diagonal is e.g. from all the way on the left and up (-2, 5) to all the way right and down (4, 0).
the middle point between 2 points is
((x1 + x2)/2, (y1 + y2)/2)
so, here

Slopes of parallel/Purpendicular lines - What is the slope of a line parallel to the line whose equation is x + 2y = -14
Explanation:
First we solve for y.
x + 2y = -14
2y = -14 - x
2y = -x - 14
y = (-x - 14)/2
y = -x/2 - 14/2
y = (-1/2)x - 7
The equation is in slope intercept form y = mx+b
m = -1/2 = slopeb = -7 = y interceptParallel lines have equal slopes, but different y intercepts. This means the slope of any line parallel to this given one will have a slope of -1/2
For example, y = (-1/2)x + 10 is parallel to y = (-1/2)x - 7, since both have the same slope of -1/2 but different y intercepts.

The solution of the system of equations by using substitution method is x = 1 and y = 3
How to use substitution method to solve system of equations?The substitution method is a method for solving systems of equations. It involves solving for one variable in one of the equations and then substituting that value into the other equation to find the value of the other variable.
We have the equations 4x + 4y = 16 and y = x+2
Substitute y = x +2 into 4x + 4y = 16:
4x + 4y = 16
4x + 4(x +2) = 16
Clear the parenthesis:
4x + 4x + 8 = 16
8x + 8 = 16
8x = 16-8
8x = 8
x = 8/8
x = 1
