The answer is 7081/1000
Step-by-step explanation:
7 = 7×1 = 7×1000/1000 = 7000/1000
7000/1000 + 81/1000 = 7081/1000
this can't be further simplified, as the only factors of 1000 are
2 and 5 and then multiples of them.
neither of them can be a factor of 7081 (which is clearly neither an even number nor a multiple of 5).

For 6 days this week, the number of defective golf clubs produced by a production line
were 210, 225, 206, 214, 180, 225. Find the mean number of defects per day.
Answer:
210
Step-by-step explanation:
The mean=210
When your doing mean next time this is how you do it. you add up all the numbers so 210 225 206 214 180 and 225. The you divide by the total of numbers so there are a total of 6 numbers.
When you add up all these numbers it has a total amount of 1,260.
so what is 1,260 divided by 6? It=210.
Would you like to also know mode median and range.
Median=212
When you do median you sort the list of numbers least to greatest and the middle number is median now since there are an even amount of numbers you would use 3 and 4 since were on 6 and do the middle between them 2 so 210 and 214.
The middle number between them is 212 and that's your answer,
Mode=All the numbers above and for the list of numbers here,all the numbers appear the same amount of times because dealing with mode,mode is the number or numbers that appears most in the data set,and for this one they all appear once.
Range=45
Range is the highest number-the lowest number so 225-180=45.
Minimum is 180 because minimum is the lowest number in the data set.
Maximum is 225 because maximum is the highest number in the data set.
Hope it helps have a great day:)
The hawk moth is the fastest flying insect. It can fly up to 33.3 miles per hour. A hornet can fly up to 13.3 miles per hour. About how much faster can the moth fly than the hornet?
Answer:
"The maximum speeds we found were approaching, you know, approximately 100 kilometers an hour; they can go incredibly fast," says Chapman. That means millions of moths fly together at about 60 miles an hour. That's faster than many birds migrate.

Find the distance between the pair of points.(-5, -8) and (4,4). What is the distance?
Answer:
label a graph doing -5,-8, and 4,4 use the formula which is
d = ( x 2 − x 1 )^2 + ( y 2 − y 1 )^2
x2-x1 = 4–2= 2 Y2–Y1 = 1–3 = -2 d=√(2)^2+(-2)^2 =√4+4 = √8 d= 2√2

Trigonometry SIN/CON
I need help for numbers 22, 24, 26, 28, 30, 32, 34, 36
Answers are in bold.
22. b/c
24. sqrt(17)/17
26. 1/4
28. sqrt(17)/17
30. 1/2
32. sqrt(2)/2
34. sqrt(3)/2
36. Approximately 5.4077 units
=====================================================
Explanation:
Problem 22
To get the cosine ratio, we divide the adjacent over hypotenuse.
cos(angle) = adjacent/hypotenuse
cos(x) = b/c
----------------------------------
Problem 24
To get the sine ratio, we divide opposite over hypotenuse.
[tex]\sin\left(\text{angle}\right) = \frac{\text{opposite}}{\text{hypotenuse}}\\\\\sin\left(\text{x}\right) = \frac{2}{2\sqrt{17}}\\\\\sin\left(\text{x}\right) = \frac{1}{\sqrt{17}}\\\\\sin\left(\text{x}\right) = \frac{1*\sqrt{17}}{\sqrt{17}*\sqrt{17}}\\\\\sin\left(\text{x}\right) = \boldsymbol{\frac{\sqrt{17}}{17}}\\\\[/tex]
In the fourth step, I multiplied top and bottom by sqrt(17) to rationalize the denominator.
----------------------------------
Problem 26
tan(angle) = opposite/adjacent
tan(x) = 2/8
tan(x) = 1/4
----------------------------------
Problem 28
cos(y) = sin(x) in this case. The general rule is that sin(A) = cos(B) if and only if A+B = 90.
Therefore the answer is exactly identical to problem 24.
----------------------------------
Problem 30
sin(30) = 1/2 is something you either memorize or look up on a reference chart, or use the unit circle. Alternatively, you can use a 30-60-90 triangle template.
----------------------------------
Problem 32
[tex]\sin\left(45^{\circ}\right) = \boldsymbol{\frac{\sqrt{2}}{2}}\\\\[/tex] is something you memorize or have on a reference sheet. You could also use a 45-45-90 triangle.
----------------------------------
Problem 34
[tex]\cos\left(30^{\circ}\right) = \boldsymbol{\frac{\sqrt{3}}{2}}\\\\[/tex] is similar to problems 30 and 32 in that you should memorize this or have it on a reference sheet. You could use a 30-60-90 triangle template here.
----------------------------------
Problem 36
Let x be the length of side AC.
Use the tangent ratio to find x.
tan(angle) = opposite/adjacent
tan(B) = AC/AB
tan(31) = x/9
x = 9*tan(31)
x = 5.4077 approximately

y-1/4x=-1
y-2=4x
one solution, no solution or infinite solution?
Answer:
One solution
Step-by-step explanation:
To start, let's simplify the equations to slope-intercept form
y - 1/4x = =1
+1/4x +1/4x
y = 1/4x - 1
y - 2 = 4x
+2 +2
y = 4x + 2
As you can see, the equations do not have anything in common worth mentioning. The slopes are different and the y-intercepts are different, so there must be only one solution.

If a carton contains 6 eggs, how many eggs are there in 13 cartons?
Answer: 78 eggs
Step-by-step explanation:
We can set up a ratio.
Let x be the amount of eggs in 13 cartons.
Then, [tex]\frac{1 carton}{6 eggs} = \frac{13 cartons}{x eggs}[/tex]
Now we can cross multiply and we get x = 78 eggs
The total number of eggs in the 13 cartons is 78.
What is the total number of eggs in the 13 cartons?Given the parameters:
Number of eggs in one carton = 6 eggs
Number of cartons = 13
Total number of eggs in 13 cartons =?
To determine the total number of eggs in 13 cartons, you simply multiply the number of eggs per carton (6) by the number of cartons (13).
Using the multiplication method:
Total number of eggs = Number of eggs in one carton × Number of cartons
Plug in the values:
Total number of eggs = 6 eggs/carton × 13 cartons
Total number of eggs = 6 eggs × 13
Total number of eggs = 78 eggs
Therefore, the total number of eggs is 78.

(d) .
Enter your answer in accordance to the item d) of the question statement
(Round the answer to 1 decimal place.)
The value of the z score form the normal distribution table will be 1.96, 2.58, 0.91, and 0.0014.
What is a normal distribution?It should be noted that a normal distribution simply means a probability distribution which is symmetric about the mean.
From the complete question, value of the z score form the normal distribution table will be calculated thus:
P(-z < Z < z) = 0.95
1 - P(Z < - z) - P(Z > z) = 0.95
1 - P(Z > z) - P(Z > z) = 0.95
1 - 2 × P(Z > z) = 0.95
P(Z > z) = (1 - 0.95)/2 = 0.025
This will be 1.96 from the normal probability table.
For P(-z < Z < z) = 0.99
1 - P(Z < - z) - P(Z > z) = 0.99
1 - P(Z > z) - P(Z > z) = 0.99
1 - 2 × P(Z > z) = 0.99
P(Z > z) = (1 - 0.99)/2 = 0.005
This will be 2.58 from the normal probability table.
For P(-z < Z < z) = 0.64
1 - P(Z < - z) - P(Z > z) = 0.64
1 - P(Z > z) - P(Z > z) = 0.64
1 - 2 × P(Z > z) = 0.64
P(Z > z) = (1 - 0.64)/2 = 0.18
This will be 0.91 from the normal probability table.
For P(-z < Z < z) = 0.9973
1 - P(Z < - z) - P(Z > z) = 0.9973
1 - P(Z > z) - P(Z > z) = 0.9973
1 - 2 × P(Z > z) = 0.9973
P(Z > z) = (1 - 0.9973)/2 = 0.0014
This will be 2.99 from the normal probability table.
Therefore, the correct options are 1.96, 2.58, 0.91, and 0.0014.

Answer:
3(2v - 3)(3v + 2)
Step-by-step explanation:
18v² - 15v - 18 ← factor out 3 from each term
= 3(6v² - 5v - 6) ← factor the quadratic
consider the factors of the product of the coefficient of the v² term and the constant term which sum to give the coefficient of the v- term.
product = 6 × - 6 = - 36 and sum = - 5
the factors are - 9 and + 4
use these factors to split the v- term
6v² - 9v + 4v - 6 ( factor the first/second and third/fourth terms )
= 3v(2v - 3) + 2(2v - 3) ← factor out (2v - 3) from each term
= (2v - 3)(3v + 2)

18v² - 15v - 18 = 3(2v - 3)(3v + 2)

Discuss each of the following descriptions. How precise is the information they supply? (A) The sweatshirt comes in small,
medium, or large. (B) The dress is a size 14. (C) The engagement ring is a size 6.
Answer:
Step-by-step explanation:
An engagement ring is likely very precise. The ring sizes used by some jewelers differs from the next size by 0.8 mm. As a % that's .8 / 16.5 * 100 = 4.80 %
The 0.8 is the number of mm needed to go from a size 6 to a size 7 ring size. So if you are ever going to buy a ring, be sure and let a jeweler measure the finger that it will go on.
The 16.5 mm is the diameter of the ring in mm. for a size 6 ring. If you have different information, you should go with what you have,
Size 14 dress
I can't answer this: it depends on where you live -- Europe or the US.
Also the type of dress matters: is it a skirt or a skirt and blouse combination. The % of the sides is much larger than 4% for the ring but it is still a definite description.
Small Medium or Large
Depends entirely on where the garment is made, and where it is being sold.
Wish tells you to add a size if you live in North America. This too is not very distinct.

Mr. Easmon drew triangle JKL, with a height of 18 inches and a base of 18 inches, and triangle XYZ, with a height of 16 inches and a base of 20 inches. Which triangle has the greater area.
Answer:
Triangle JKL
Step-by-step explanation:
The formula to find the area of a triangle is :area (A) = (height (H) x base (B)) / 2
You are given the height and base of both triangles, so you just have to plug in the numbers.
Triangles JKL: A = (18 x 18) / 2
A = 162 in^2
Triangel XYZ: A = (16 x 20) / 2
A = 160 in^2
162 is greater than 160, so Triangle JKL has a larger area.
