how other statistucal values are used to summarize data
Statistics regularly employs tables, charts, and graphs to present data visually.
What is meant by statistical values?Data can be summarized graphically or numerically (see "Graphical techniques in Statistics" for further information on the latter). The methods for numerical and graphical summarization that can be utilized depend on the type of data that was collected.
Statistics regularly employs tables, charts, and graphs to present data visually. The evaluation of raw data for patterns, data entry errors, and outlier values that can affect the statistical interpretation of the data is frequently started with examples like these.
It is important to show the data in tables, charts, and other statistical figures in a way that is both accurate and simple to understand. Additionally, tables are helpful for distilling the original data that forms the basis of a study's findings. To convey a lot of information in a small amount of area, they are effective.

Step-by-step explanation:
The hourly rate is 8 dollars because $52-$44 is $8. $44-$36 is also $8. So $36- (the amount for 2 hours) $28 is $8. so in one hour the cost to rent a bicycle is $8.
Given (x – 7)2 = 36, select the values of x. x = 13 x = 1 x = –29 x = 42
The values of x in the equation are (a) x = 13 and (b) x = 1
How to determine the values of x for the equation?From the question, we have the following parameters that can be used in our computation:
(x - 7)2 = 36
This equation when expressed properly is
(x - 7)² = 36
Take the square roots of both sides of the equation
So, we have the following representation
x - 7 = ±6
Add 7 to both sides of the equation
This gives
x = 7 ± 6
Evaluate the sum and the difference
x = 1 and 13
Hence, the solutions are (a) and (b)

a basketball player claims to make 47% of her shots from the field. we want to simulate the player taking sets of 10 shots, assuming that her claim is true. a total of 25 repetitions of a simulation were performed. the number of makes in each set of 10 simulated shots was recorded on the dotplot as shown below. suppose this player attempts 10 shots in a game and makes only 3 of them. does this provide convincing evidence that she is less than a 47% shooter?
Since the probability is 33% which is less than 47% as claimed by the basketball player, it can be concluded that there is convincing evidence that she is less than a 47% shooter.
It is given to us that -
A basketball player claims to make 47% of her shots from the field
The player takes sets of 10 shots
Assuming that her claim is true, a total of 25 repetitions of a simulation were performed
The number of makes in each set of 10 simulated shots was recorded on the dot plot
We have to suppose this player attempts 10 shots in a game and makes only 3 of them.
For the simulation of the player taking sets of 10 shots, we have to determine if we have enough convincing evidence that she is less than a 47% shooter.
From the given information, the approximate probability of finding out that a 47% shooter makes only 3 of the 10 attempted shots can be determined as -
P (x = 3) = 3/10 = 0.33 = 33%
Since the probability is 33% which is less than 47% as claimed by the basketball player, it can be concluded that there is convincing evidence that she is less than a 47% shooter.

How do you convert 2 as a percentage?
suppose that $1,000 is deposited into an account that yields 0.85% interest, compounded annually? how much money will be in that account at the end of 4 years?
The money at the end of 4 years will be $1034.
What is compound interest ?
The interest on the initial investment as well as the interest that has accrued on that investment are both referred to as compound interest, or "compounding interest."
Given, P = $1,000
Rate (r) = 0.85% p.a.
time (t) = 4 years
We know that, Amount = P ( 1 + r/100 )^t
The money in account after 4 years will be :
= P ( 1 + r/100 )^t
= $1,000 × ( 1 + 0.85/100 )^4
= $1,000 × 1.0085^4

The perimeter of a square is 60 cm. Find the
area of the square.
Step-by-step explanation:
SOLUTIONSince a perimeter is a total distance around the figure.
And a square is a quadrilateral(with four sides) which are equal.To find the length of each side,divide the perimeter by 4.
60 cm÷4 = 15 cmSince,Area of square = side×side = 15cm×15cm = 225cm^2hope it helps you.
Answer:
Area of square = 225 cm²
Step-by-step explanation:
Perimeter of square formula,
→ P = 4 × side
→ P = 4a
Now the side of square will be,
→ P = 4a
→ 4a = 60
→ a = 60/4
→ [ a = 15 cm ]
Then the area of square will be,
→ (a)²
→ (15)²
→ 225 cm²
Hence, area of square is 225 cm².

Which value of x makes the equation 3-0.5(2x-8)=(3X+28) true
Step-by-step explanation:
In order to solve this equation, you will need to use the following steps:
First, simplify the left side of the equation by performing the operation of multiplying 0.5 and (2x-8) to get 0.5(2x-8)=x-4.
Then, subtract 3 from both sides of the equation to get x-4=3x+28.
Next, subtract 3x from both sides of the equation to get -3x+x-4=28.
Combine the like terms on the left side of the equation to get -2x-4=28.
Add 4 to both sides of the equation to get -2x=32.
Finally, divide both sides of the equation by -2 to get x=16.
Therefore, the value of x that makes the equation 3-0.5(2x-8)=(3x+28) true is 16.
What is the sum of all digits in the sequence 1,2,3,4... 98,99,100? (For example, the sum of digits in 34 and 35 is 3+4+3+5=15)
Answer:
Step-by-step explanation:
To find the sum of all the digits in the sequence 1, 2, 3, ..., 98, 99, 100, we can use a bit of arithmetic.
First, let's find the sum of the digits in the first 99 numbers of the sequence. Each number in the sequence has two digits, so the sum of the digits in the first 99 numbers is 99 * 18 = 1872.
Next, we need to add in the digits in the number 100. The sum of the digits in 100 is 1 + 0 + 0 = 1.
Therefore, the sum of all the digits in the sequence 1, 2, 3, ..., 98, 99, 100 is 1872 + 1 = 1873.

The distance between (2, 3) and (1, 7) is:
117.
1.
16.
17.
Answer:
Sqrt of 4²+ (-1)² = Sqrt. of 17
Step-by-step explanation:
2 points in a coordinate grid create a right-angled triangle.
the distance is the Hypotenuse (the side opposite of the 90° angle). and the x coordinate and y coordinate differences are the legs.
and with that we use Pythagoras
c² = a² + b²
with c being the Hypotenuse, and a and b being the legs.
so, in our case :
distance² = (1 - 2)² + (7 - 3)² = (-1)² + 4² = 1 + 16 = 17
distance = sqrt(17)

Here,
Therefore ,the limitations of generalizing census findings back to the entire population are:-
The homeless population is underrepresented in the findings even though every home is required to complete a census report. This is because they are frequently impossible to reach, interview, and count.
People who do not speak either English or Spanish as their first language and whose primary language is one of those two are more likely to be overlooked in the census.
Since surveys rely on self-reporting, some misrepresentation or mistake is unavoidable.
The population fluctuates constantly, so it is unlikely that the population on the day the census results are released would closely resemble the population as described in the census.

the double integral.3xy2 x2 + 1dA, R = {(x, y) | 0 ≤ x ≤ 1, −2 ≤ y ≤ 2}
∫∫3xy2 dx dy = 16
We start by calculating the limits of integration. The given region, R, is bounded by 0 ≤ x ≤ 1 and −2 ≤ y ≤ 2. This means that the double integral is:
∫∫3xy2 dx dy = ∫0→1∫-2→2 3xy2 dx dy
Next, we will calculate the integral with respect to x. We can easily do this by integrating 3xy2 with respect to x. This gives us the following:
∫0→1 3xy2 dx = x3y2 + c
Now, we can substitute this expression into the double integral, giving us:
∫∫3xy2 dx dy = ∫0→1 (x3y2 + c) dy
Finally, we can integrate this expression with respect to y, giving us the following:
∫∫3xy2 dx dy = x3y3 + cy + d
Now, we can substitute the limits of integration into this expression, giving us the following:
∫∫3xy2 dx dy = 1(32) + c(-2) + d = 16
therefore, the double integral is equal to 16.

The correct ordering of the graphs from least value of n to greatest value of n is A, B, C.
The three graphs, A, B, and C, represent the results of three simulations of a sampling distribution of a sample mean. Graph A has a value of n of 200, Graph B has a value of n of 200 and Graph C has a value of n of 0. Thus, the correct ordering of the graphs from least value of n to greatest value of n is A, B, C. To understand this, it is important to note that as the value of n increases, the sample means will be more representative of the population. Therefore, Graph A with the lowest value of n would have the least representative sample means, followed by Graph B and Graph C with the highest value of n having the most representative sample means.
