there are 4 new students. they are holding a pep rally to introduce them. how many different ways can they be introduced

The correct answer is: Triangle MNO

A reflection of a triangle over the X-axis involves flipping the triangle about this axis. Each point in triangle ABC (A, B, and C) is reflected to a corresponding point A', B', and C' in the reflected triangle such that their Y-coordinates are negated while the X-coordinates remain the same.

To understand the concept of the reflection of a triangle, you need to visualize flipping the triangle over a line, in this case, the X-axis. When a triangle named ABC is reflected over the X-axis, the positions of the points change as follows: A (x, y) becomes A' (x,-y), B (x, y) becomes B' (x, -y), and C (x, y) becomes C' (x, -y). Therefore, the triangle that is a reflection of triangle ABC over the X-axis is triangle A'B'C'.

The correct answer is: descriptive and inferential statistics.

Step-by-step explanation:

The two branches of the study of statistics are generally referred to as descriptive and inferential statistics.

Descriptive statistics are the brief summary statistic which summarizes a given data set, which can be a representation of the entire population or just a sample of it.

While Inferential statistics is the way data analysis is used to deduce the properties of an underlying probability distribution.

The study of statistics generally branches into descriptive statistics, which involves summarizing and displaying data, and inferential statistics, which makes predictions about a population based on sampled data.

The two branches of the study of statistics are generally referred to as descriptive statistics and inferential statistics. Descriptive statistics involves the organization, summarization, and display of data. It seeks to describe a situation or sample population without offering any conclusions or inferences about the data. Examples include calculating averages, measures of central tendency like mean, median, mode, and variability measures such as range, variance, and above all standard deviation.

On the other hand, inferential statistics is a method to make predictions or inferences about a population based on a sample of data. It is used when it is not practical or impossible to examine the entire population. Examples of inferential statistics methods include hypothesis testing, chi-square tests, t-tests, ANOVA, regression analysis etc.

Hope this helps

Answer: First option

Step-by-step explanation:

By definition, you know that:

[tex]55\°=\frac{170\°-x}{2}[/tex]

Therefore, to calculate the measure of the missing angle, you must solve for x, as you can see below:

- Multiply both sides of the equation by 2.

- Subtract 170 from both sides of the equation.

- Multiply both sides of the equation by -1

Therefore:

[tex]55\°=\frac{170\°-x}{2}\\\\(2)55\°=\frac{170\°-x}{2}(2)\\\\110\°=170\°-x\\110\°-170\°=170\°-x-170\°\\(-1)-60\°=-x(-1)\\x=60\°[/tex]

Step-by-step explanation:

Final answer:

The volume of the shoe box is calculated using the formula for the volume of a rectangular prism, resulting in a total of 450 cubic inches.

Explanation:

The formula for finding the volume of a rectangular prism (which is the shape of a shoe box) is Volume = Length × Width × Height. However, before calculating, we need to ensure all dimensions are in the same unit. Since the given width is in mixed number form, we will convert 6 2/3 inches to an improper fraction which is 20/3 inches. We then multiply the length, width, and height.

Volume = (13.5 inches) × (20/3 inches) × (5 inches)
Volume = (13.5 × 20/3 × 5) cubic inches
Volume = (270/3 × 5) cubic inches
Volume = (90 × 5) cubic inches
Volume = 450 cubic inches

The shoe box's volume is 450 cubic inches.

Answer:

f(x)⁻¹ = x³ + 2

Step-by-step explanation:

Find the inverse of f(x) = ∛(x - 2).

The first step is to let f(x) = y

y =  ∛(x - 2)

Then make x the subject of the formula

y³ =  [∛(x - 2)]³

y³ = x - 2

x = y³ + 2

∴ f(x)⁻¹ = y³ + 2

Replacing y with x we have.

f(x)⁻¹ = x³ + 2

The veterinarian gave each cat 1/5 of a bottle of medicine. By dividing the total medicine (2/5 of a bottle) by 1/5, we find that there were 2 sick cats.

To find the number of sick cats, we need to divide the amount of medicine given to the cats by the amount given to each cat. Since each cat received 1/5 of a bottle, we can divide the total medicine (2/5 of a bottle) by 1/5 to find the number of cats. This can be done by multiplying the total medicine by the reciprocal of 1/5, which is 5/1.

Therefore, there were 2 sick cats.

Answer:

a.  $1,377.20

Step-by-step explanation:

To determine the annual premium for the policy, you have to divide the face value by 1,000:

$55,000/1,000= $55

Then, you have to multiply this result for the rate found on the table, which according to the information given is $25.04:

$55*$25.04= $1,377.20

The annual premium for the policy is $1,377.20.

A = sinx - sin3x,  

B = -sin3x + sin5x  

First A:  

The average of x and 3x is 2x, and they (x and 3x, that is) are each a distance of x from this average. That's fancy talk for:  

x = 2x-x,  

3x = 2x+x.  

So, A = sin(2x-x) - sin(2x+x)  

Using angle sum formulas:  

A = (sin2x cosx - cos2x sinx) - (sin2x cosx + cos2x sinx)  

A = -2 cos2x sinx  

Similarly,  

B = -sin(4x-x) + sin(4x+x)  

= -(sin4x cosx - cos4x sinx) + (sin4x cosx + cos4x sinx)  

B = 2 cos4x sinx  

Now,  

sinx - 2sin3x + sin5x = A+B = -2 cos2x sinx + 2 cos4x sinx  

= 2 sinx (cos4x - cos2x).  

Sinx-2sin3x+sin5x=2sinx(cos4x-cos2x)  

sinx - 2sin3x + sin5x = sinx - sin(3x) + sin(5x)- sin(3x)

=  2· cos[(x+3x)/2] · sin[(x-3x)/2] + 2·cos[(5x+3x)/2]· sin[(5x-3x)/2]

= 2· cos(2x) ·sin(-x) + 2· cos(4x) · sin(x)

=  -2·cos(2x)·sinx + 2· cos(4x)·sinx

=  2·sinx · [ cos(4x)- cos(2x)]

Answer:

20 miles

Step-by-step explanation:

The formula for distance is

d =rt  where r  is the rate and t is the time

We need to convert the time to hours since the rate is in mph

15 minutes * 1 hour/ 60 minutes = 1/4 hour = .25 hours

d = (80 mph) * .25 hours

d = 20 miles

The train goes 80 miles in an hour which is 60 minutes. 60 minutes divided by 15 minutes equals 4. 80 miles divided by 4 equals 20 miles. The train went 20 miles in 15 minutes.

To find out how much ribbon is left after using 1/2 yard from a piece that is 7/8 yard long, convert 1/2 yard to 4/8 and subtract from 7/8, leaving you with 3/8 yard of ribbon remaining.

To determine how much ribbon will remain after using 1/2 yard for a craft project from a piece that measures 7/8 yard, you need to subtract the amount used from the total length you have. Since we are working in yards, ensure both amounts are in the same units. Here are the steps to find the remaining ribbon:

Start with the total length of ribbon: 7/8 yard.

Subtract the length of ribbon used for the project: 1/2 yard.

Convert 1/2 yard to an equivalent fraction with a denominator of 8, which is 4/8 yard.

Subtract 4/8 yard from 7/8 yard to find the remaining length.

7/8 yard - 4/8 yard = 3/8 yard remaining.

So, after using 1/2 yard of ribbon for a craft project, you will have 3/8 yard of ribbon left from the original 7/8 yard piece.

Step-by-step explanation:

To find the area of the unshaded portion of a figure containing a trapezoid and a rhombus, calculate the area of each figure first using their respective formulas. Subtract the area of the overlapping (shaded) region from the total to find the area of the unshaded portion.

The problem asks to find the area of the unshaded portion of a figure, which includes a trapezoid and a rhombus. Since we don't have the specific values of the sides and heights of each figure, a general approach would be to calculate the area of each figure first, then subtract the area of the shaded (overlapping) region from it.

The formula for the area of a trapezoid is A = 1/2 (a+b)h, where 'a' and 'b' are the lengths of the parallel sides and 'h' is the height. For the rhombus, the formula is A = 1/2 (d1 * d2), where 'd1' and 'd2' are the diagonals.

Assuming you can measure and determine the shaded region, you would compute its area as well and subtract this from the total of the previous two calculations. This would give you the area of the unshaded portion.

Answer:

[tex]h = -2\\h = 6[/tex]

Step-by-step explanation:

The absolute value is a function that transforms any value x into a positive number.

Therefore, for the function [tex]f(x) = |x|[/tex]  x> 0 for all real numbers.

Then the equation:

[tex]|h-2| = 4[/tex] has two cases

[tex](h-2) = 4[/tex]    if [tex]h > 2[/tex]  (i)

[tex]-(h-2) = 4[/tex]    if [tex]h < 2[/tex] (ii)

We solve the case (i)

[tex]h = 4 + 2\\h = 6[/tex]

We solve the case (ii)

[tex]-h +2 = 4\\h = 2-4\\h = -2[/tex]
