What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
6x - 12y = 15................(1)
2x - 4y = 6...........(2)
Now, Multiply equation (2) by 3 we get
6x - 12y = 15
6x - 12y = 18
____________
0 = -3
also, 6/2 = -12/ (-4) ≠ 15/6 which is parallel lines.

18. A set of data has a sample mean of 65.4 and a standard deviation of 1.2. If the sample size is 45, what is the 99% confidence interval of this data?
A. 65.10 and 65.70
B. 65.33 and 65.47
C. 65.05 and 65.75
D. 64.94 and 65.86
Given:
Sample mean = 65.4
Standard deviation = 1.2
Sample size = 45
Confidence level = 99%
To find:
The confidence interval.
Solution:
The formula for confidence interval is
[tex]CI=\overline{x}\pm z^*\dfrac{s}{\sqrt{n}}[/tex]
where, [tex]\overline{x}[/tex] is sample mean, z* is confidence value, s is standard deviation and n is sample size.
Confidence value or z-value at 99% = 2.58
Putting the given in the above formula, we get
[tex]CI=65.4\pm 2.58\times \dfrac{1.2}{\sqrt{45}}[/tex]
[tex]CI=65.4\pm 0.46[/tex]
[tex]CI=65.4-0.46\text{ and }CI=65.4+0.46[/tex]
[tex]CI=64.94\text{ and }65.86[/tex]
Therefore, the correct option is D.

A recent report indicated that 22 percent of the households in a certain community speak a language other than English at home. A reporter will randomly select a household from the community until the first household that speaks a language other than English at home is selected. Let random variable Q represent the number of attempts needed until the first household that speaks a language other than English at home is selected. The random variable Q has a geometric distribution with p=0.22. Which of the following is closest to the variance of the random variable?
(A) 0.0484
(B) 2.5454
(C) 4.5455
(D) 4.0144
(E) 16.1157
Answer:
(E) 16.1157
Step-by-step explanation:
Q has geometric distribution with p = 0.22
"Variance of Q" V(Q) = 1 - p / p²
V(Q) = 1 - 0.22 / 0.22²
V(Q) = 0.78 / 0.0484
V(Q) = 16.11570247933884
V(Q) = 16.1157
So, the Variance of random variable Q is 16.1157
This question is based on the variance. Hence, the correct option is D i.e. 16.1157 is closest to the variance of the random variable.
Given:
Community speak a language other than English at home = 22 percent
Let random variable Q represent the number of attempts needed.
The random variable Q has a geometric distribution with p=0.22.
We need to determined the closest to the variance of random variable.
As we know that,
Q has a geometric distribution with p=0.22
Now calculate the variance of Q,
[tex]V(Q)=\dfrac{1-p}{p^{2} }[/tex]
[tex]V(Q)=\dfrac{1-0.22}{0.22^{2} }[/tex]
[tex]V(Q)=\dfrac{0.78}{0.484} }[/tex]
Therefore, the variance V(Q) is 16.1157.
Hence, the correct option is D i.e. 16.1157 is closest to the variance of the random variable.

Step-by-step explanation:
The Main Rules Are:
1) A negative number times a negative number is a positive number.
2) A positive number times a positive number is a positive number.
3) A negative number times a positive number is a negative number.
This problem is read as negative 1 times negative 6. Any negative symbol in front of a parentheses would be read as negative 1. In other words, the problem reads -1(-6). Remember, a negative number times a negative number is a positive number. Multiplying negatives is no different than multiplying numbers greater than zero, you just change the sign of the answer. Lets read this as 1 times 6 which is 6. Therefore, -1 times -6 is 6.

The binomial theorem states that for some a,b∈R and some k ∈Z+ ,
(a+b)k=∑n=0k(kn)ak−nbn.
The binomial series allows us to use the binomial theorem for instances when k is not a positive integer. The binomial series applies to a given function f(x)=(1+x)k for any k∈R with the condition that |x|<1 . It is stated as follows:
(1+x)k=∑n=0∞(kn)xn .
Note that the binomial theorem produces a finite sum and the binomial series produces an infinite sum.
The binomial series enables us to apply the binomial theorem when k is not a positive integer.

Determine the key features of a function whose value is defined as six less than triple some quantity. (2 points)
The slope is _____
the x-coordinate of the x-
Intercept is_____
and the y-coordinate of the y-intercept is_____
:: 6
:: 2
:: 3
:: 1/3
:: -6
Can y’all help me put three of these options in the right places :)
Answer:
The slope is 3
Hence the x-coordinate of the x- intercept is 2
Hence the y-coordinate of the y- intercept is -6
Step-by-step explanation:
We are to first write the statement six less than triple some quantity as an expression:
let the quantity be x
Triple the quantity to have 3x
six less than triple some quantity will be expressed 3x - 6
The required function is f(x) = 3x - 6
This is in standard form of equation of a line y = mx+c
m is the slope
c is the y-intercept
Comparing 3x - 6 with mx+c
3x = mx
3 = m
m = 3
The slope is 3
x intercept occurs at when f(x) = 0
Substitute into f(x) = 3x-6
0 = 3x-6
-3x = -6
x = 2
Hence the x-coordinate of the x- intercept is 2
y intercept occurs at when x = 0
Substitute into f(x) = 3x-6
f(x) = 3(0)-6
f(x) = -6
Hence the y-coordinate of the y- intercept is -6
