The estimate of the sum by rounding each number to the nearest tenth is 0.8
How to estimate the sum by rounding each number to the nearest tenth?Estimation is a method used for calculating the approximate value of a quantity (just to get a 'rough answer')
In estimation 1, 2,3, and 4 are rounded down while 5, 6, 7, 8 and 9 are rounded up.
Rounding each number to the nearest tenth:
0.214 = 0.2
0.61 = 0.6
The sum = 0.2 + 0.6 = 0.8

summerize this:
I didn’t know what I was doing or what I believed in, except the United States of America and the Cleveland Browns. Sometimes, to break my addiction to the tube[1], I spent the night in a derelict shed with mushrooms growing from the rafter boards. Back-yard rehab. I used to read in there, or, anyway, swing my eyes over the pages of library books: “Out of Africa” (the girl I was in love with loved the move); Donal Trump’s autobiography; Kierkegaard; “Leaves of Grass”; a book about how to make a robot from an eight-track player. As long as nobody had assigned the book, I could stick with it. I didn’t know what I was reading. I didn’t really know how to read. Reading messed with my brain in an unaccountable way. It made me happy; or something. I copied out the first paragraph of Annie Dillard’s “An American Childhood” on my bedroom’s dormer wall. The book was a present from an ace teacher, a literary evangelist in classy shoes, who also flunked me, of course, with good reason. Even to myself I was a lost cause.
Q#1HASF & Company produces cleaning kits for shotguns. The production capacity available will enable the firm to produce 50,000 kits annually. A projected income statement for next year shows
Sales 460,000

Selling and administrative expenses 125,000
Net income 39,000
Fixed manufacturing overhead costs 40% of the cost of goods sold. Regular selling price per unit is 10 A 10% sales commission is paid to sales representatives for each kit sold. The purchasing department of a large discount chain has offered to purchase 1500 kits at $6 each. Company sales manager’s initial response is to refuse the offer because he concludes that the $6 price is below the firm’s average cost The sales commission would not be paid on the special order.

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.
Answer:
the answer is, 64.94 and 65.86
Step-by-step explanation:
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.

Choose the answer that shows 5–15 rewritten using a positive exponent.
Answer:
The required answer is [tex]\dfrac{1}{5^{15}}[/tex].
Step-by-step explanation:
Consider the provided exponent.
The given exponent is [tex]5^{-15}[/tex].
We need to write it using a positive exponent.
So, use the property: [tex]a^{-m}=\dfrac{1}{a^m}[/tex]
By using the above property we can rewrite the given exponent as:
[tex]5^{-15}=\dfrac{1}{5^{15}}[/tex]
Hence, the required answer is [tex]\dfrac{1}{5^{15}}[/tex].

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.

Answer: A
Step-by-step explanation:
In this equation, the largest exponent is odd, so the two ends are going in different directions. Since the leading coefficient is positive, the left side is going down, while the right side is going up.
As y approaches negative infinity (goes down), x approaches negative infinity (goes left).
Simplified: as the y value decreases, the x value decreases.
As y approaches infinity (goes up), x approaches infinity (goes right).
Simplified: as the y value increases, the x value increases.

What is the equation of the line? Identify the values of A, B, and C in the standard form of the equation.
Answer:
Find the Equation of a Line Given That You Know Two Points it Passes Through. The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
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
