Answers
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.

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.
Answers
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:)
If a carton contains 6 eggs, how many eggs are there in 13 cartons?
Answers
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.

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.

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.
Answers
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.

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 )

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.
Answers
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.
