What is mean median and mode 7th grade?
The three statistical measures of central tendency are mean, median, and mode. While describing a set of data, we point out its primary location. This is referred to as the central tendency measure.
The arithmetic mean of a given data is the sum of all observations divided by the number of observations.
The data set's median is the value in the center. Put all the numbers in ascending or descending order, and then choose the middle number to determine the median. There will only be one middle integer if the number of data points is odd. If the number of data points is even, you must choose the middle two numbers, add them together, and divide by two. Your median will be that value.
A mode is defined as the value that has a higher frequency in a given set of values. It is the value that appears the most number of times.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is

Now , substituting the limits in the equation , we get
[tex]ln f ( x ) = x [ \int\limits^1_0 {( - ln t+ ln (tx+1)-lnt-ln(t^{2} x^{2}+1)+lnt^{2}] } \, dt[/tex]
Substitute the value of tx = z in the equation , we get
[tex]ln f ( x ) = \int\limits^1_0 {ln\frac{(1+z)}{1+z^{2} } } \, dz[/tex]
Taking exponential on both sides of the equation , we get

Differentiating with respect to x , we get
[tex]\frac{f' (x ) }{f ( x ) } = ln\frac{1+x}{1+x^{2} }[/tex]
Now , on further simplification of the equation , we get
f ( x ) > 0 for x > 0
And , f' ( x ) > 0
[tex]ln\frac{1+x}{1+x^{2} } > 0[/tex]

What is rigid transformations?The separation between each pair of the geometric object's points is preserved during a rigorous change of the object. In other words, a rigid transformation maintains the object's size and shape. For instance, the rigid transformation of a triangle retains the angles and lengths of the triangle. Imagine a stiff shape distortion, similar to a cardboard shape. The form remains the same after being pushed left and right, rotated, and flipped. When the mold was created using putty, the opposite was true. The thing can then be twisted and stretched. These conversions, nevertheless, are not exact.

The expression that you can use to find the number of ways to choose 5 cards from a 52-card deck is 52 choose 5, which is equal to 52!/(47! * 5!), where the exclamation point indicates the factorial function. This is known as the binomial coefficient, and it represents the number of ways to choose a certain number of items from a larger set. In this case, the binomial coefficient is used to find the number of ways to choose 5 cards from a deck of 52 cards.
The order of the cards is irrelevant in card games like poker. A five-card draw of 1,2,7,9, K is equivalent to a draw of K,7,9,1,2. What counts is the fundamental overall group.
Order is irrelevant, therefore we utilize a combination (instead of a permutation)

Tim needs a new car while he attends college in the United States for the next three years. The car he would like has a MSRP of $15,000. A local dealer can get him a 3-year loan with a 7% interest rate if Tim can give them a $1,500 down payment.
The same dealer offers the same car to lease with a money factor of 0.00271 and a residual value of 75%. The lease requires an additional fee of $1,250 to cover Tim’s security deposit and the acquisition and documentation fees for the car.
Tim is looking to drive the car home with the smallest initial out-of-pocket cost. Which of the following statements is true?
a.The initial out-of-pocket cost is less for the lease.
b.The initial out-of-pocket cost is less for the loan.
c.The initial out-of-pocket cost is the same for the lease and loan.
d.The initial out-of-pocket cost for a lease is not comparable to that of a loan.
Answer:
A
Step-by-step explanation:
To compare the initial out-of-pocket cost for the lease and loan options, we need to calculate the total cost for each option.
For the loan option, we can calculate the total cost as follows:
Total cost = MSRP + down payment + interest
= $15,000 + $1,500 + $1,050 (7% of MSRP)
= $17,550
For the lease option, we can calculate the total cost as follows:
Total cost = (MSRP x money factor x 36) + acquisition and documentation fees + security deposit
= ($15,000 x 0.00271 x 36) + $1,250
= $5,925 + $1,250
= $7,175
Since the total cost for the lease option is less than the total cost for the loan option, the initial out-of-pocket cost is less for the lease. Therefore, the correct statement is:
a. The initial out-of-pocket cost is less for the lease.
A boat heading out to sea starts out at Point A, at a horizontal distance of 1032 feet
from a lighthouse/the shore. From that point, the boat's crew measures the angle of
elevation to the lighthouse's beacon-light from that point to be 15°. At some later
time, the crew measures the angle of elevation from point B to be 6°. Find the
distance from point A to point B. Round your answer to the nearest tenth of a foot if
necessary.
Answer:
1598.9 ft
Step-by-step explanation:
You want the distance between points A and B when observers at each point find the angle of elevation to a lighthouse beacon to be 15° and 6°, respectively. Point A is 1032 ft horizontal distance from the lighthouse.
TangentThe tangent relation for sides in a right triangle is ...
Tan = Opposite/Adjacent
This can be rearranged to ...
Opposite = Tan × Adjacent
SetupIf d is the distance in feet from A to B, two expressions for the same lighthouse height can be written:
height = tan(15°)(1032)
height = tan(6°)(1032 +d)
SolutionEquating these values of height, we have ...
tan(6°)(1032 +d) = tan(15°)(1032)
d = 1032(tan(15°) -tan(6°))/tan(6°) = 1032(tan(15°)/tan(6°) -1)
d ≈ 1598.946 . . . . feet
The distance from A to B is about 1598.9 feet.

How do you tell the end behavior of a graph from an equation?
The end behavior of a graph can be determined by looking at the leading term in the equation. If the leading term is a positive or negative power of x, then the end behavior of the graph will be either a horizontal asymptoteor an oblique asymptote. If the leading term is a constant, then the end behavior of the graph will be a horizontal line at that constant value.
To determine the end behavior of a graph from an equation, we first look at the leading term in the equation. If the leading term is a positive or negative power of x, then the end behavior of the graph will be either a horizontal asymptote (positive or negative infinity) or an oblique asymptote (slanted line). If the leading term is a constant, then the end behavior of the graph will be a horizontal line at that constant value. For example, if the leading term of an equation is 3x2, then the end behavior of the graph will be a horizontal asymptote at positive infinity. If the leading term of the equation is 4, then the end behavior of the graph will be a horizontal line at y=4. To determine the exact shape of the asymptote, we must look at the coefficient of the leading term. A positive coefficient will create a positive asymptote (sloping up), while a negative coefficient will create a negative asymptote (sloping down). Additionally, if the graph oscillates around a single point, then the end behavior of the graph is a limit cycle.

2/5 x 1/4 = X
0.4 x 0.25 = X
0.1 = X
0.1 x 100 = 10
Therefore, the probability that Hamid guesses both answers correctly is 10%.

What is a perpendicular slope example?
Examples of perpendicular slope are the sides of a fixed square, a window, and the Red Cross emblem.
Describe perpendicular slope.Lines that are vertical and horizontal are perpendicular to one another. In this instance, the perpendicular line's slope would be equal to a horizontal line's slope, which would be 0. The slope of the perpendicular line is zero, but the slope of the parallel line is unknown. By taking the negative reciprocal of the slope of the provided line, one can determine the slope of a perpendicular line from that line. We obtain m2 = -1/m1 if the slope of the provided line is m1 and the slope of a perpendicular line is m2.
Given
There are a lot of perpendicular lines that we may see in reality. The corners of the chalkboard, the arms of a clock at specific times of the day, the sides of a fixed square, a window, and the Red Cross emblem are a few examples.

a new trendy restaurant is growing exponentially. after being open for 11 months the restaurant was serving an average of 310 customers a day. by month 15, the restaurant was serving about 456 customers a day. write an exponential function n(t) that models average number of customers, n, after t months of being open. if necessary, round any values to four decimal places (do not round on intermediate steps). write your answer in the form a(b)t
the exponential function is n(t) =n° (1+r)∧t, where t is the power refers the time in months after opening and n denotes average customer.
what means growing exponentially?when the rate of increases is occurred very rapidly. In this question, the trendy restaurant has earned reputation.
How will be the exponential function?Given, average number of customers after 11 months of opening = n(11) =310
average number of customers after 15 months of opening= n(15) =456
during this 4 month increases of customer =456 -310 =146
increasing rate of customer per month = 146/4 = 36.5
now increasing rate in percentages = 36.5 %
exponential growth rate, r= 0.365
let, n° is the initial number of customer while opening at t=0 month
now, the exponential function n(t) that model's average number of customers, n after t months of being open will be
n(t) = n° ( 1+r)∧t
we are given that after 11 months of opening average customer n(11) = 310
now, 310 = n° (1+ 0.365)∧11
n° = 10
hence, the exponential function = n(t) = 10(1+r)∧t

What equation can be formed that would relate the width length and the area of the room?
The equation that makes relationship between width, length and area of a room is Area of room = length of room × width of room and perimeter of room = 2× (length of room + width of room)
How to calculate the size of a room?The size of a room is either square or rectangle in shape. Whenever a room is rectangle shaped, we need to measure all the side lengths and finally area is found by product of two unequal side length. Besides, we can determine the perimeter of room by adding the two unequal side length and finally 2 is multiplied with it.
What is the formula for rectangle or square?We stated earlier that the size of a room is either rectangle or square.
area of square shaped room = (side length× side length)
area of rectangle shaped room = (bigger side length × smaller side length)
perimeter of square shaped room = 4 × side length = 4√(area of room)
perimeter of rectangle shaped room = 2(bigger side length + smaller side length)
hence, the above equations make relationship among the width, length, area and perimeter of a room.
