Some have proposed that the playing a card game previously worked as "play cash" and addressed the stakes utilized for other betting games, and later turned out to be essential for the actual games. Others have proposed associations between playing a card game and chess or dice games, yet this is again theoretical. Different games, for example, a 25-card variation of Euchre which involves the Joker as the most elevated trump, make it one of the main in the game.

Which statement about the points (5, 7) and (10, 12) is true? CLEAR CHECK There is not enough information to determine if the points show direct variation. They show direct variation because y = x + 2 and 10 – 5 = 12 – 7. The line they are on does not show direct variation. They show direct variation because the line they are on has a positive slope.
Step-by-step explanation:
direct variation means that
y = kx
that means it is a line with y-intercept = 0.
in other words, when x = 0, then y = 0 too.
for 2 given points the first part is automatically true. 2 points always define a line.
so, what we need to find out is, if (0, 0) is also on the line.
if not, it is not a direct variation.
the 2 points imply the equation
y = x + 2
as the y value is always larger than the x value by 2.
this has a y-intercept larger than 0 (2).
and so, (0, 0) is NOT on the line, and it is NOT a direct variation.
so, the 3rd answer option is correct.

given the function h(x)=x^2-9x+18, determine the average rate of change of the function over the interval 4<_ x <_ 11
To calculate average rate of change of a function f(x) over an interval between 2 points (a. f(a)) and (b, f(b)) is given by
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
The given function is [tex]h(x)= x^{2} -9x+18[/tex]
and the given interval is [tex]4\leq x\leq 11[/tex]
Now, h(b) = h(11) = [tex](11)^{2} -9(11)+18[/tex]
= [tex]121-99+18[/tex]
= [tex]40[/tex]
h(a) = h(4) = [tex](4)^{2} -9(4)+18[/tex]
= [tex]16 -36+18[/tex]

The average rate of change between (4, -2) and (11, 40) is

The mean, which is a measure of central tendency for quantitative data should not be used for likert scale data values, which are ordinal (qualitative) data.
The use of the mean as a measure of central tendency for ordinal data may be encountered, in the customer satisfaction data analysis systems used in some banks
What is ordinal data?Ordinal data are a data form that specified categories that are scaled or have a set order.
However, ordinal scales are not standard, such that they cannot be manipulated quantitatively.
The mean specifies the average value, which the sum of the quantitative measurements, divided by the number of measurements

Step-by-step explanation:
Given polynomial:
[tex]f(x)=6x^2+7x^2-x-2[/tex]
[tex]\boxed{\begin{minipage}{6 cm}\underline{Factor Theorem}\\\\If $f(x)$ is a polynomial, and $f(a) = 0$,\\ then $(x-a)$ is a factor of $f(x)$.\\\end{minipage}}[/tex]
Since the constant of the given polynomial is -2, the possible factors are ±1 and ±2.
Apply the Factor Theorem to check the possible values:
[tex]f(1)=6(1)^3+7(1)^2-(1)-2=10 \neq 0[/tex]
[tex]f(-1)=6(-1)^3+7(-1)^2-(-1)-2=0[/tex]
[tex]f(2)=6(2)^3+7(2)^2-(2)-2=72 \neq 0[/tex]
[tex]f(-2)=6(-2)^3+7(-2)^2-(-2)-2=-20 \neq 0[/tex]
Therefore, (x + 1) is a factor of the polynomial:
[tex]f(x)=(x+1)(ax^2+bx+c)[/tex]
Compare with the original function to find the coefficients of the quadratic:
[tex]6x^3=ax^3 \implies a=6[/tex]
[tex]7x^2=(b+a)x^2 \implies b=1[/tex]
[tex]-2=c \implies c=-2[/tex]
Therefore:
[tex]f(x)=(x+1)(6x^2+x-2)[/tex]
Factor the quadratic:
[tex]f(x)=(x+1)(6x^2+4x-3x-2)[/tex]
[tex]f(x)=(x+1)[2x(3x+2)-1(3x+2)][/tex]
[tex]f(x)=(x+1)(2x-1)(3x+2)[/tex]
Set the polynomial function to zero:
[tex](x+1)(2x-1)(3x+2)=0[/tex]
Apply the zero product property:
[tex](x+1)=0 \implies x=-1[/tex]
[tex](2x-1)=0 \implies x=\dfrac{1}{2}[/tex]
[tex](3x+2)=0 \implies x=-\dfrac{2}{3}[/tex]
Therefore, the solutions are:

To find the ratio of blue balloons to the total number of balloons, firstly we need to find the number of blue balloons. Performing addition and subtraction for the same as follows -
Total number of balloons = Number of blue balloons + number of red balloons + number of white balloons
Number of blue balloons = 14 - (3 + 4)
Number of blue balloons = 14 - 7
Number of blue balloons = 7
