6-12+24x+12x-6+24x+12x-6+36x or 36x-6A 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.

Imagine that a car and a truck both have the same speed on the road. Which one can stop easily ? Of course , it is hard to stop the truck relative to the car. The reason is that the car and the truck have the same speed bit different masses. Thus , we can say that to stop a heavier body is harder than to stop a lighter one even both of them have the same speed.
If two tennis balls are hit towards you in different velocities , it is not equally easier to stop them. The ball in more velocity is difficult to stop relatively. Thus , we can say that to stop a body in more velocity is harder than to stop a body with less velocity , eventhough they have the same speed.
The physical quantity that describes the quantity of motion of a body is called momentum. The momentum of a moving body or linear momentum is defined as the product of mass & velocity of a moving body.
Mathematically ,
Momentum = mass × velocity
i.e p = m × v
The SI unit of momentum is kg • m/s. Since velocity is a vector quantity and multiplied with mass ( scalar quantity) , momentum becomes a vector quantity. Direction of momentum is the same as velocity.

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.
What is the binomial theorem?The binomial theorem (or binomial expansion) in elementary algebra describes the algebraic expansion of binomial powers.

The law used to simplify the given expression (x⁴)⁹ is D) Power of a power law.
What are Exponents?Exponents are the method of writing numbers, especially large numbers, in terms of a base and an exponent, which is written as the power of base.
Given expression is (x⁴)⁹.
Power of a power rule is the rule of the exponents which states that if a number in the base is raised to some power, which is again raised to another power, then both the powers will get multiplied leaving the base as same.
We can use this rule here, since the base x is raised to 4, which is again raised to 9.
Using the rule,
(x⁴)⁹ = (x)⁽⁴⁾⁽⁹⁾ = x³⁶
Hence the rule used is power of a power rule.

Step-by-step explanation:
Answer:
D: 6
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.

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]

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
