Answer: 8 = 1x + 2y

Step-by-step explanation:

this could be multiple answers, is this a multiple-choice question? follow that equation to find the answer that fits.

I got the equation by these steps:

total money spent is $8, so you start with 8 =

you don't know the specific number of pens so make that x. the cost of pens is $1, so the total cost will be $1 times however many pencils are bought, ie 1x.

repeat that for pencils, replacing $1 with $2, and making pencils mean y. you get 2y.

now to find your answer, insert numbers into x and y until they equal 8.

possible answers:

x=4, y=1

x=2, y=2

x=0, y=4

a) The point estimate of the proportion of the population that would provide Yes responses is; 0.50

b) The estimate of the standard error of the proportion is; 0.0224

c) The 95% confidence interval for the population proportion is; CI = (0.4569, 0.5431)

a) The point estimate of proportion in a sample of n out of which x belongs to the favorable event is;

p^ = x/n

Thus, we are given; x = 250 and n = 500

p^ = 250/500

p^ = 0.5

b) The standard error  is defined as a statistical term that measures the accuracy with which a sample distribution represents a population by using standard deviation. It is given by the formula;

S = √(p^(1 - p^)/n)

Plugging in the relevant values gives;

S = √(0.5(1 - 0.5)/500)

S = 0.0224

c) A confidence interval is defined as the mean of your estimate plus and minus the variation in that estimate. The confidence interval is given by the formula;

CI = p^ ± z√(p^(1 - p^)/n)

where z is z-score at confidence level

z at 95% confidence level = 1.96

Thus;

CI = 0.5 ± 1.96√(0.5(1 - 0.5)/500)

CI = 0.5 ± 0.04312

CI = (0.4569, 0.5431)

Greatest common factor (GCF): 12a³b + 8a²b² - 20ab³. = 4ab(3a² + 2ab - 5b²) that is option 2

A group of numbers' greatest common factor (GCF) is the biggest factor that all the numbers have in common. For instance, the numbers 12, 20, and 24 share the components 2 and 4. Since four is the biggest, we refer to the GCF of 12, 20, and 24 as four.

There are two stages to get the GCF since 12a3b + 8a2b2 - 20ab3. contains both integers and variables (HCF). Find GCF for the variable component first, then for the numeric part.

How to locate GCF

1. Find the GCF for the 12, 8, 20 numerical portion.

2. Calculate the GCF for the variable component (a3b, a2b2, and ab3).

3. Add the values together and multiple them

Find the common factors for the numerical part: 12 ,8,20 is

factors of 12 -1,2,3 ,4,6,12

factors of 8 - 1,2,4,8,

factor of 20 - 1,2,4,5,10,20

the common factor will be 1,2,4

so GCF = 4

Next, find the common factors for the variable part: a³b , ,a²b² ,ab³.

the common factors will be ab

so GCF = ab

for the equation 12a³b + 8a²b² - 20ab³.

4ab is common , if we take 4ab common then remaining parts are

12a³b = 3a²

8a²b² = 2ab

20ab³. = 5b²

greatest common factor: 12a³b + 8a²b² - 20ab³. = 4ab(3a² + 2ab - 5b²)

The equation of the exponential function represented by the table will be:

[tex]f(x) = 2(4)^{x}[/tex]

An exponential function is a Mathematical function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.

We know the equation of exponential function such as

[tex]f(x) = ab^{x}[/tex]

Put x=0, and y=2 in the function

[tex]2 = ab^{0} \\2 = a[/tex]

Also x=1, and y=8 in the function

[tex]8 = 2b^{1} \\b = 4[/tex]

The probability of growing seed exactly one is 0.0033.

The probability of a seed not growing is 0.46, because if it has a 54% chance of growing, then  100% - 54% to find the odds that it will not grow, which is 46%.

The probability of 7 seeds growing is equivalent to asking what the probability is of a seed growing and another seed growing and another seed growing and another seed, and so on until I say a total of 7seeds. The point is that "and" in probability means to multiply.

To calculate the likelihood of seven seeds growing,

(0.46)(0.54)⁷

Probability = 0.0033

Probability = 0.0033 x 100

Yes, it wasn't fair because some kids got more pizza.

What is simplest form of a fraction?

When the numerator (top) and denominator (bottom) of the fraction do not have any common factors, the fraction is said to be in its simplest form. For instance, 1/2 is the most basic version of 6/12.

Given that, there were 14 players.

Six players sat at one table and got 4 small pizzas to share equally.

Applying unitary method,

Thus each players got 4/6 part of a pizza.

                                    = 2/3 [ Divide denominator and numerator by 2]

The other 8 players sat at a different table and got 6 small pizzas to share equally.

Each players got 6/8 part of a pizza.

                            = 3/4 [Divide denominator and numerator by 2]

Now compare 2/3 and 3/4:

The LCM of the denominators 3 and 4 is 12.

Multiply 4 with denominator and numerator of 2/3:

(2×4)/(3×4) = 8/12

Multiply 3 with denominator and numerator of 3/4:

(3×3)/(4×3) = 9/12

Therefore, 9/12 >  8/12

Interval notation

The domain is the set of all possible input values (x-values).

The range is the set of all possible output values (y-values).

From inspection of the graph, the endpoints of the continuous curve are:

As the endpoints are open circles, the x-values are excluded from the domain.  Therefore, the domain in interval notation is:

The smallest y-value is y = -6 and the greatest y-value is y = 2.  

y = -6 is excluded from the range since it is the y-value of the open circle endpoint, whereas y = 2 is included in the range.  Therefore, the range in interval notation is:

The graph is a function as is each input (x-value) is related to exactly one output (y-value).

From inspection of the graph, the endpoints of the continuous line are:

As the graph is a straight line, the x and y values of the endpoints are the x and y values of the domain and range.

As the (-6, -1) endpoint is an open circle, the values are excluded from the domain and range.

As the (6, 5) endpoint is a closed circle, the values are included in the domain and range.

Therefore, the domain and range in interval notation are:

The graph is a function as is each input (x-value) is related to exactly one output (y-value).

Answer:

  (c)  F

Step-by-step explanation:

You want the different names for the angles shown, and for their parts.

This question is about naming bits of geometry. Here, you're mainly naming rays and combinations that form angles. A ray is always named by naming its end point first, then another point on the ray. An angle is formed by two rays with a common end point.

An angle can be named by naming rays that form it (with the vertex in the middle of the name), by naming the vertex alone (if that is unambiguous), or by using a designator, such as ∠2.

Angle 2 is made from rays FH and FE, so can be named either of ...

If ray FG were not present, it could also be named angle F, the name of the vertex point.

The 3-letter angle name tells you the names of the sides. The end point of each ray must be named first in the ray name. It is named in the middle of the angle name.

The vertex of angle 1 is the point that is also the vertex of angle 2:

Answer: FAT32

you're welcome :D

Answer:

use fat32

FAT32 is regarded as the default file system for external drives, especially the removable USB flash drives and SD memory cards. It's the most compatible file system that can be used on major devices and operating systems like Windows and macOS. So, the advantage of using FAT32 is portability.

However, FAT32 has some disadvantages, or let's say limitations as well. First and foremost, if you use a single file over 4GB in size, you'll need to convert FAT32 to NTFS or exFAT; What's more, due to the manufacturers' specifications, FAT32 can only be used to format drives between 2GB and 32GB, and that's why native tools on Windows have that limit, too. When you try to format a USB drive over 32GB in Windows Explorer, there is no "FAT32" option at all.

Answer:

If the slope of a line is negative, it means that the line is sloping downward from left to right. In other words, as the value of x increases, the value of y decreases. This is in contrast to a positive slope, where as the value of x increases, the value of y also increases. So, if the slope of the line y = x is changed to a negative value, the line will still have the same general shape, but it will be flipped upside-down and will slope downward from left to right
