Hope this helps!
Answer 2

Answer:

Annual income for all 150 employees at a local high school

Step-by-step explanation:

The normal distribution is also called the Gaussian distribution. It is the most common type of distribution for statistical analysis. The normal distribution is based on a probability distribution. The data near the mean are more frequent than the data away from the mean. It is based on two parameters: the mean and the standard deviation.

As per options, option A which states ‘annual income for all 150 employees at a local high school’ the data is within the standard deviation.

We have the slope of the new equation and one point is given.

Plot BOTH into the point-slope formula and solve for y. To solve for a variable means to isolate the variable ALONE on one side of the equation.

y - y_1 = m(x - x_1)...This is the point-slope formula. Our given point is (5,-2)

y - 5 = -5(x - (-2))

y - 5 = -5(x + 2)

We now solve for y and that's it.

y - 5 = -5x - 10

y = -5x - 10 + 5

Final answer:

The type of question that fits a binomial model is a true/false question, as this type of question strictly limits the outcome to two possibilities - correct or incorrect.

Explanation:

The type of question that fits into a binomial model would be a true/false question. A binomial distribution, in mathematics and statistics, is used to model a number of successes in a sequence of independent and identically distributed binary experiments, such as flipping a coin or indeed, answering a true/false question. These types of questions are considered binomial because there are two possible outcomes: right or wrong, true or false. On the other hand, options like 'fill in the blank', 'matching', or 'multiple choice' doesn't fit the binomial model because they do not strictly limit the outcome to two possibilities.

Answers

11 I think because they started with 12 got three more then loaned 4 out
Final answer:

The Greenville Art Museum currently has 11 sculptures on display after receiving 3 more sculptures and then loaning out 4 sculptures.

Explanation:

The Greenville Art Museum initially had 12 sculptures on display. They added 3 more sculptures to their collection, which increased the total number of sculptures to 15. Afterwards, they loaned out 4 sculptures to another museum. To find out how many sculptures are still at the Greenville Art Museum, we subtract the number of sculptures loaned out from the total.

Starting with 15 sculptures, after loaning out 4, we do the following calculation:

15 - 4 = 11 sculptures

Therefore, the Greenville Art Museum now has 11 sculptures on display.

To burn 1 molecule of c7h16 to form co2 and h2o (complete combustion), how many molecules of o2 are required?

Answers

Final answer:

Eleven molecules of O2 are required to completely combust one molecule of C7H16, producing CO2 and H2O. The balanced chemical reaction of this process is: C7H16 + 11O2 → 7CO2 + 8H2O.

Explanation:

Combustion of one molecule of C7H16 (heptane) to produce CO2 (carbon dioxide) and H2O (water) requires 11 molecules of O2 (oxygen). The balanced chemical equation of this reaction is:

C7H16 + 11O2 → 7CO2 + 8H2O

The equation shows that for every one molecule (or mole) of C7H16, 11 molecules (or 11 moles) of oxygen are needed. An analogy can be seen in the combustion of methane where one methane molecule and two oxygen molecules react to yield one carbon dioxide molecule and two water molecules.

What is y=-4x-15 in standard form

Answers

y=-4x-15
4x + y = -15 ...this is standard form

hope it helps

Final answer:

To convert the equation y = -4x - 15 to standard form, you add 4x to both sides to get 4x + y = -15, which aligns with the standard form Ax + By = C.

Explanation:

To convert the equation y = -4x - 15 into standard form, we need to rearrange it such that the x- and y-terms are on one side of the equation and the constant is on the other side, typically with the x term first. The standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A should be non-negative.

The given equation is already close to this form, but we need to get the x-term to the other side of the equation. To do this, we simply add 4x to both sides, giving us:

4x + y = -15

This is the standard form of the given linear equation.

Rename 12,000 ten thousand

Answers

120,000 or twelve thousand 10,000
Final answer:

Renaming 12,000 as 'ten thousand' means expressing it as '1 ten thousand and 2 thousand'. This breaks the number down into units of ten thousand, with 10,000 being the base unit and the additional 2,000 making up the rest.

Explanation:

The phrase 'rename 12,000 ten thousand' refers to the process of expressing the number 12,000 in terms of ten thousand. To do this, we need to understand that the number 10,000 is a base unit in this context, acting as one 'ten thousand'. Therefore, the number 12,000 would be considered as 1 ten thousand and 2 thousand, since 12,000 is made up of one 10,000 and an additional 2,000 units.

To better understand, let's do a breakdown:

10,000 (one ten thousand) + 2,000 (two thousand) = 12,000

We know that:

10,000 is one ten thousand.20,000 is two ten thousands.30,000 is three ten thousands.And so on, up to 160,000, which would be sixteen ten thousands.

In this case, when we want to 'rename' 12,000 as ten thousand, it becomes 1 ten thousand and 2 thousand.

A combination of numbers, variables, and at least one operation is called an expression. It involves the use of variables and operators to represent mathematical relationships or operations. Expressions are fundamental in algebra for solving problems and describing mathematical properties.

Explanation:

A combination of numbers, variables, and at least one operation is called an expression. An expression is a mathematical statement that combines values, variables (which are symbols that represent unspecified numbers), and operators (special symbols that represent computations like addition, subtraction, multiplication, and division) to describe a sequence of operations that yield a single result. For example, the expression 5 - 3xy combines the numbers 5 and 3, the variable y, and the operations of subtraction and multiplication to form a single mathematical statement.

If you are passing a large tractor trailer rig going 50 mph, how long will it take to pass if you use the correct passing techniques?

Answers

If you are passing a large tractor trailer rig going 50 mph it will take you the time it takes to go 50 mphs for the distance of the tractor. Taking safety into account it should take you double of the amount of time that it would because it is important to slow down to 25 mph when passing.

To pass a truck going 55 mph while you go 60 mph, it will take about 8.94 seconds if using the correct passing techniques. This calculation is based on the relative speed and the total distance required to pass the truck.

First, consider the difference in speeds between the car and the truck. Assuming the truck is going 55 mph as stated in the reference information, and the car speeds up to 60 mph:

Calculate the relative speed:
Relative Speed = Car Speed - Truck Speed = 60 mph - 55 mph = 5 mphConvert this relative speed from mph to meters per second:
1 mph ≈ 0.44704 m/s
Relative Speed = 5 mph × 0.44704 ≈ 2.2352 m/sCalculate the total distance to pass the truck:
The truck is 17 m long and the car is 3 m long, so the car needs to cover its own length plus the truck's length to pass completely:
Total Distance = 17 m + 3 m = 20 mFinally, determine the time taken to pass:
Time = Distance / Relative Speed = 20 m / 2.2352 m/s ≈ 8.94 seconds

Therefore, it will take approximately 8.94 seconds to pass the truck completely.

Answers

To illustrate, I’ve printed out a paper hexagon and creased it along the axes of symmetry listed in your question. When we say a shape can “carry onto itself,” we mean that reflecting it along a specific line will keep the shape’s position and orientation completely identical to how it started. If you can imagine creasing and folding the shape along that line, the shapes on either side of the fold would be exactly the same.

As you can see from my example, a line from an angle to the midpoint of one of the pentagon’s sides I the only fold that meets this requirement.

Find f(-1) (inverse) if y=4x+2/3x-1 and x is not equal with 1/3

Answers

Before we find [tex]f^{-1}[/tex], let's think for a minute about what [tex]f[/tex] does, and what it means to find the inverse of a function. A function [tex]f[/tex] essentially takes a value [tex]x[/tex] from the domain and maps it to another value [tex]y[/tex] in that function's range according to a set of rules. Here, those rules are defined by the formula

[tex]y= \frac{4x+2}{3x-1} , x \neq \frac{1}{3} [/tex]

All the inverse does is swap the domain and range of the function. Now, instead of trying to map [tex]x[/tex] to [tex]y[/tex], we're trying to find a set of rules that'll map [tex]y[/tex] back to [tex]x[/tex]. To find those rules, all we have to do is solve the above equation for [tex]x[/tex].

First, we'll multiply both sides of the equation by [tex]3x-1[/tex] to get it out of the denominator:

[tex](3x-1)y=( \frac{4x+2}{3x-1})(3x-1) [/tex]

Cancelling on the right side and distributing on the left, we get:

[tex]3xy-y=4x+2[/tex]

Next, we collect all of our x terms on one side, and all of our non-x terms on the other:

[tex](3xy-y)+y=(4x+2)+y\\(3xy)-4x=(4x+2+y)-4x\\3xy-4x=2+y[/tex]

Let's rearrange the right side and factor out an x on the left:

[tex]x(3y-4)=y+2[/tex]

And finally, we divide both sides by [tex]3y-4[/tex] to obtain our answer:

[tex][x(3y-4)]/(3y-4)=(y+2)/(3y-4)\\\\x= \frac{y+2}{3y-4} [/tex]

This equation gives us the "rules" for mapping any given y in the range back to an x in the domain. If we swap the domain and the range, we can define our function 

[tex]f^{-1}(x)= \frac{x+2}{3x-4}[/tex]

a. rational numbers

b. rational numbers, irrational numbers

c. natural numbers, whole numbers, integers, rational numbers

Answers

118 belongs in a. rational numbers



Answer:

a. rational numbers

Step-by-step explanation:

The number is between integers, so it can't be an integer or a whole number.

In general, 1.18 belongs to three sets of numbers.

Firstly, it is a rational number because it can be written in the form p/q where p and q are integers and q is not equal to zero.

1.18=[tex]\frac{118}{100}[/tex]

Secondly, all rational numbers are also real numbers and all real numbers are complex numbers.

But we have been given to choose from only rational numbers, irrational numbers, natural numbers or whole numbers.

So, the only answer is rational number.
