Answer: D or the Fourth Choice-The quotient of 14 and 8 tenths divided by 2 plus the product of 6 and 3 minus 12
PEDMAS means Parentheses, Exponents, Divide, Multiply,Add,Subtract. The first thing we must solve is what is in the parentheses, that is 14.8 divided by 2. We don't have any exponents, so we move to divide. We have already solved the division sentence that was in the parentheses, so we have to multiply 6x3 next. 6x3 will then be added to the answer that was divided by 14.2 and 2, and lastly we will subtract 12. The only answer choice that follows that pattern is D or The quotient of 14 and 8 tenths divided by 2 plus the product of 6 and 3 minus 12.

The slope of the line is -1, and the y-intercept is 4.
What is linear function ?
A linear function is a type of mathematical function where the graph of the function is a straight line. It is a function that has a constant rate of change (or slope) between any two points on the line.
In the form of the equation y = mx + b, where m is the slope of the line and b is the y-intercept (the point at which the line crosses the y-axis). This equation represents a linear function since the graph of the function is a straight line.
Linear functions are used in many areas of mathematics and science, as well as in real-world applications such as engineering, economics, and physics. They are useful in modeling and predicting relationships between variables that have a constant rate of change over time.
To find the equation of the linear function in the form y = mx + b, we need to determine the slope (m) and y-intercept (b) of the line.
From the graph, we can see that the y-intercept is 4, since the line intersects the y-axis at the point (0, 4).
To find the slope, we can choose two points on the line and use the slope formula:
slope (m) = (y2 - y1) / (x2 - x1)
Let's choose the points (2, 6) and (6, 2):
slope (m) = (2 - 6) / (6 - 2) = -4 / 4 = -1
Therefore, the equation of the linear function is:
y = -x + 4
So, the slope of the line is -1, and the y-intercept is 4.

A survey found that women's heights are normally distributed with mean 63.4 in and standard deviation 2.5 in. A branch of the military requires women's heights to be between 58 in and 80 in. a. Find the percentage of women meeting the height requirement. Are many women being denied the opportunity to join this branch of the military because they are too short or too tall? b. If this branch of the military changes the height requirements so that all women are eligible except the shortest 1% and the tallest 2%, what are the new height requirements?
After answering the provided question, we can conclude that As a result, normal distribution the new height requirement for women to join this branch of the military is 57.1 inches to 68.6 inches.
what is normal distribution?The normal distribution is an example of a constant distribution of probabilities, in which the majority of the points cluster near the range's center and the ones that are left decrease symmetrically towards one of the extremes. The mean of the spread is another term for the range's centre. According to the bell curve, also known as the Distribution function, which is symmetrical well about mean, data that are near the median are more frequent than data that are far from the mean. I'm using heuristics in normality to obtain a child's SAT scores from an innovative exam prep course. The data have a normal distribution with a mean (M) of 1150 and a standard deviation (SD) of 150.
a. To calculate the percentage of women who meet the height requirement, find the area under the normal distribution curve between 58 and 80 inches.
For x = 58 inches: z = (58 - 63.4) / 2.5 = -2.16
For x = 80 inches: z = (80 - 63.4) / 2.5 = 6.64
This means that all women with heights ranging from 58 to 80 inches meet the requirement.
b. For the shortest 1%, we need to find the height that corresponds to z = -2.33:
-2.33 = (x - 63.4) / 2.5
x = 57.1 inches
So the new minimum height requirement is 57.1 inches.
For the tallest 2%, we need to find the height that corresponds to z = 2.05:
2.05 = (x - 63.4) / 2.5
x = 68.6 inches
So the new maximum height requirement is 68.6 inches.
As a result, the new height requirement for women to join this branch of the military is 57.1 inches to 68.6 inches.

Simplify each difference. 7) (1 + 2x) - (6x+2-524)
the simplified difference is -1 - 4x + 524. To simplify the difference (1 + 2x) - (6x+2-524), we need to first distribute the negative sign to the second expression inside the parentheses:
(1 + 2x) - (6x+2-524) = 1 + 2x - 6x - 2 + 524
Now we can simplify by combining like terms:
1 + 2x - 6x - 2 + 524 = (1 - 2) + (2x - 6x) + 524
Simplifying further:
-1 - 4x + 524
Therefore, the simplified difference is -1 - 4x + 524.
It's worth noting that this expression could be simplified further by combining like terms, but it depends on the context and purpose of the expression.

a middle school classroom contains 15 students. out of them, nine are boys. a teamis to be formed with ten students, of them six must be boys. in how many ways can the team be formed?
As per the combination method, there are 1260 ways in which a team of 10 students with 6 boys and 4 girls can be formed from a middle school classroom containing 15 students with 9 boys.
To solve this problem, we need to use the concept of combinations. A combination is a way of selecting items from a larger group where the order of selection does not matter. In this problem, we are selecting a team of 10 students, and the order in which we select the students does not matter.
Using this formula, we can find the number of ways to select 6 boys from a group of 9 as:
⁹C₆ = 9! / (6! x (9-6)!) = 84
Similarly, the number of ways to select 4 girls from a group of 6 is:
⁶C₄ = 6! / (4! x (6-4)!) = 15
To find the total number of ways to form a team of 10 students with 6 boys and 4 girls, we need to multiply the number of ways to select 6 boys and 4 girls. This is because the selection of boys and girls is independent of each other, and we can choose them in any order.

In 1980 a value of home is 81600 since then it's value has increased by 12 percentage each year what is the appoxmate value of the home in the 1987 round to the nearest hundred dollars
The approximate value of the home in 1987 is approximately $161,872.
The formula to calculate the approximate value of a home in 1987 is:
V1987 = 81600 x (1 + 0.12)^7
V1987 = 81600 x 1.987
V1987 = 161872
Therefore, the approximate value of the home in 1987 is approximately 161,872.
To arrive at this answer, we first started with the value of the home in 1980, which was 81,600. We then multiplied this value by 1.12, which is the 12% increase every year, to the seventh power. This resulted in a value of 1.987. We then multiplied this value by the original value of the home in 1980, which gave us the approximate value of the home in 1987. We then rounded the answer to the nearest hundred dollars, which resulted in the answer of 161,872.

where h is the height of the tower, d is the horizontal distance from the base of the tower to the point where the cable is attached, and θ is the angle of depression that we want to find.
From the diagram, we can see that
tan(θ) = h / d
We know that the length of the cable is 500 feet and the horizontal distance from the base of the tower to the point where the cable is attached is 350 feet. We can use the Pythagorean theorem to find the height of the tower:
h^2 = 500^2 - 350^2
h = sqrt(500^2 - 350^2)
h = 300
Now we can substitute the values we have found into the equation for tan(θ) to get:
tan(θ) = 300 / 350
θ = tan^-1(300/350)
θ ≈ 41.4 degrees

What is the slope of the line y = 2.5x - 7
Answer:
2.5
Step-by-step explanation:
The slope of the line represented by the equation y = 2.5x - 7 is 2.5. This means that for every unit increase in x, the value of y increases by 2.5 units.
The slope of the line y = 2.5x - 7 can be identified as the coefficient of the 'x' variable in the equation. Here, the term in front of 'x' is 2.5, so the slope of the line is 2.5. In other words, for every unit increase in x, y will increase by 2.5 units. This is a key concept in linear equations, which are used to represent straight lines in a coordinate system.

which transformation carries the rhombus below onto itself?
1. a rotation of 180 clockwise about (-2,-2)
2. a rotation of 90 counterclockwise about (-2,-2)
3. a reflection over the line y=x+10
4. a reflection over the line y=-x-6
Therefore, the answer is option 4: a reflection over the line y=-x-6.
What is transformation?In mathematics, a transformation is a process that changes the position, size, or shape of a geometric object in some way. Transformations are often used in geometry and other branches of mathematics to study the properties of shapes and their relationships to each other.
Here,
To determine which transformation carries the rhombus onto itself, we need to identify the symmetries of the rhombus. A rhombus has two types of symmetry: rotational symmetry and reflectional symmetry.
Option 1: a rotation of 180 degrees clockwise about (-2,-2)
This transformation takes each point of the rhombus and rotates it 180 degrees clockwise about the point (-2,-2). Since the rhombus has rotational symmetry of order 2 (i.e., a rotation of 180 degrees carries the rhombus onto itself), this transformation carries the rhombus onto itself.
Option 2: a rotation of 90 degrees counterclockwise about (-2,-2)
This transformation takes each point of the rhombus and rotates it 90 degrees counterclockwise about the point (-2,-2). Since the rhombus does not have rotational symmetry of order 4 (i.e., a rotation of 90 degrees does not carry the rhombus onto itself), this transformation does not carry the rhombus onto itself.
Option 3: a reflection over the line y=x+10
This transformation reflects each point of the rhombus over the line y=x+10. Since the rhombus does not have reflectional symmetry over this line, this transformation does not carry the rhombus onto itself.
Option 4: a reflection over the line y=-x-6
This transformation reflects each point of the rhombus over the line y=-x-6. Since the rhombus has reflectional symmetry over this line, this transformation carries the rhombus onto itself.

really need help please ASAP The graph of a function is shown below.
Use the graph of the function to find its average rate of change from x=0 to x=3
Simplify your answer as much as possible.
accualy in math one but they dont have 9th grade on hear.
As a result, the function's average rate of change from x = 0 to x = 3 is 4/3 as the average rate of change of the function from x = 0 to x = 3.
what is function ?A function is a rule in mathematics that links every element of one set, known as the domain, to a certain element of some other set, known as the range. A function is just a relationship between the values of the input and the output, where the outcome specifically depends on the input. A function can be depicted in a number of different ways, including as an equation, a chart, or a list of values. For instance, the function f(x) = 2x multiplies the input value x by two to get the output value f. (x). The range of this function is indeed the set of all real numbers, and its domain is any set of real numbers.
given
To determine (3, f(3)) on the function graph the average rate of change of the function from x = 0 to x = 3.
According to the graph, the point (0, f(0)) is on the y-axis and has a y-coordinate of 2, while the point (3, f(3)) is on the line that connects the points (2, 0) and (4, 6) and has a slope of m = 3. As a result, we have:
f(0) = 2 and f(3) = 6
We can determine the slope of the line connecting these two points using the slope formula:
m = (f(3) - f(0)) / (3 - 0) = (6 - 2) / 3 = 4/3
As a result, the function's average rate of change from x = 0 to x = 3 is 4/3 as the average rate of change of the function from x = 0 to x = 3.
