The best centre of measure for this data is the mean which is equal to 10.90 seconds.
Mean, median and mode are use to measure for central tendency. Therefore, let's arrange the values in ascending order.
10.72, 10.75, 10.78, 10.80, 10.80, 10.88, 10.96, 10.99, 11.02, 11.10, 11.10,
According to the data, the values are very close to catch. Therefore, the mean will be used. Therefore,
mean = sum of data / number of data
mean = 10.72 + 10.75 + 10.78 + 10.80 + 10.80 + 10.88 + 10.96 + 10.99, 11.02 + 11.10 + 11.10 / 11
mean = 119.9 / 11
mean = 10.90

There are 58 students in a classroom with 7
tables. If 8 students can sit at a table, how
many students cannot sit down at tables?
8x7=56, so 56 students can sit at a table, 58-56=2 students without a table.
Your answer would be 2.
Answer:
2 students cannot sit down at tables.
Step-by-step explanation:
Since there are a total of 58 students and only 7 tables and each table can only fit 8 students, you'll need to calculate how many students can sit at 7 tables first:
7(8) = 56 So, with 8 students sitting at all 7 tables, there are 56 students that can sit at a table.
To find how many students can't sit at a table you'll have to subtract 56 from 58,
58-56 = 2 So, 2 students will not be able to sit down at tables.

what are the lengths of sides a and b?
Answer:
[tex]a =\frac{\sqrt 3}{2}[/tex] mi
[tex]b =\frac{1}{2}[/tex] mi
Step-by-step explanation:
Given
The attached triangle
Required
Find a and b
To do this, we make use of the following trigonometry ratio
[tex]\sin(\theta) = \frac{Opposite}{Hypotenuse}[/tex]
So, we have:
[tex]\sin(60) = \frac{a}{c}[/tex]
[tex]\sin(30) = \frac{b}{c}[/tex]
Where
[tex]c = 1[/tex]
So, we have:
[tex]\sin(60) = \frac{a}{c} =\frac{a}{1}[/tex]
[tex]\sin(60) = a[/tex]
[tex]a = \sin(60)[/tex]
In radical form:
[tex]\sin(60) = \frac{\sqrt 3}{2}[/tex]
Hence:
[tex]a =\frac{\sqrt 3}{2}[/tex]
[tex]\sin(30) = \frac{b}{c}[/tex]
[tex]\sin(30) = \frac{b}{1}[/tex]
[tex]\sin(30) = b[/tex]
Rewrite as:
[tex]b =\sin(30)[/tex]
In radical form:
[tex]\sin(30) = \frac{1}{2}[/tex]
Hence:
[tex]b =\frac{1}{2}[/tex]
A class has five students. What is the probability that exactly two of the students were born on a weekend?
Answer:
This is binomial.
Here n = 5
p = 2/7
mean = np = 5*2/7 = 10/7 = 1.42857
standard deviation = sqrt(npq) = sqrt(5*2/7*5/7) = 1.01015
Step-by-step explanation:
Work Shown.
The probability that exactly two of the five students of the class were born on weekend is 0.2975
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
n = 5
The probability that any student was born on weekend, P(W) = (2 / 7)
and, the probability that any student was not born on weekend
P(W') = {1 - P(W)}
= {1 - (2 / 7)}
= (5 / 7).
Thus, the probability that exactly two of the five students of the class were born on weekend
= ([tex]^5C_2[/tex]) x {P(W)}² x {P(W')}³
= 10 x {(2 / 7)²} * {(5 / 7)³}
= 10 x (4 / 49) x (125 / 343)
= (5000 / 16807)
≈ 0.2975

Step-by-step explanation:
Just follow the rule: add each area of the net. Ignore the 22 mm because that does not represent the area. Got this question right in an assignment.
Mark Brainliest pls!
You can find the surface area by Adding 1,105.28 + 200.96 + 200.96.
What is surface area?
The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
The surface area will be calculated as:-
SA = 1,105.28 + 200.96 + 200.96.
SA = 1507.2
Therefore the surface area by Adding 1,105.28 + 200.96 + 200.96.

what is the perimeter of the triangle?
what is the area or the triangle?
Answer:
Step-by-step explanation:
Answer:
Area = 7
Perimeter = 21 m
Step-by-step explanation:
Remark
The perimeter is just the sum of the three sides of the triangle.
The Area is the base * height /2
Givens
Perimeter: Three sides: 5 + 7 + 9
height: 2 meters
Formula
Area = 1/2 Base * Height
Area = 1/2 7 * 2
Note:
Just so you know the height should be almost 5. 2 is an impossible amount for the height.
Area = 1/2 * 7 * 2
Area = 7 m^2
Perimeter = 5 + 7 + 9
Perimeter = 21
How do I solve this using the Pythagorean theorem
Answer:
x=8
Step-by-step explanation:
Remember that the variables a and b in the formula are the legs and c is the hypotenuse. So that means that 15 and x are the legs and 17 is the hypotenuse. Plug those numbers where they go in the formula like below:
15^2+x^2=17^2
Go ahead and square the 15 and 17 to simplify it a little.
225+x^2=289
Now, get the x by itself by subtracting 225 from each side
x^2=64
Take the square root of each side to remove the squared on x and solve.
x=8

A kitchen table is being sold at a furniture store. These are the cost and revenue functions associated with the tables, where x
represents the selling price of a single table:
R(X) = -0.68x2 + 310x
C(x) = 43.6x + 36,176
Which two points represent breakeven for table sales?
(0, 36,176)
(140, 30,072)
(227, 35,330)
(260, 9,792)
(380, 19,608)
Answer:
(140, 30,072) and (380, 19608).
Step-by-step explanation:
We are given that the revenue function for selling the kitchen table given its price is:
[tex]R(x)=-0.68x^2+310x[/tex]
And the cost function is:
[tex]C(x)=-43.6x+36176[/tex]
At the breakeven point, the revenue equals the cost. Therefore:
[tex]R(x)=C(x)[/tex]
Substitute:
[tex]-0.68x^2+310x=-43.6x+36176[/tex]
We can solve for x.
Adding 0.68x² to both sides and subtracting 310x from both sides yields:
[tex]0.68x^2-353.6x+36176=0[/tex]
We can use the quadratic formula:
[tex]\displaystyle x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
In this case, a = 0.68, b = -353.6, and c = 36176. Substitute:
[tex]\displaystyle x=\frac{-(-353.6)\pm\sqrt{(-353.6)^2-4(0.68)(36176)}}{2(0.68)}[/tex]
Simplify:
[tex]\displaystyle x=\frac{353.6\pm\sqrt{26684.24}}{1.36}[/tex]
So, our two solutions are:
[tex]\displaystyle x=\frac{353.6+\sqrt{26684.24}}{1.36}\text{ or } x=\frac{353.6-\sqrt{26684.24}}{1.36}[/tex]
Use a calculator:
[tex]x\approx 380\text{ or } x\approx 140[/tex]
Our answers are:
(140, 30,072) and (380, 19608).

Find the mean,median ,and mode of the following set of data Weight of the 7 fish that were caught (lbs) are: 12,3,7,8,9,12,10
Given:
The data values are:
12, 3, 7, 8, 9, 12, 10
To find:
The mean,median ,and mode for the given set of date.
Solution:
We have,
12, 3, 7, 8, 9, 12, 10
Arrange the values in ascending order.
3, 7, 8, 9, 10, 12, 12
Mean of the data set is:
[tex]\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Number of observations}}[/tex]
[tex]\text{Mean}=\dfrac{3+7+8+9+10+12+12}{7}[/tex]
[tex]\text{Mean}=\dfrac{61}{7}[/tex]
[tex]\text{Mean}\approx 8.7143[/tex]
Number of observations is 7 which is an odd number. So, the median is:
[tex]Median=\dfrac{n+1}{2}\text{th term}[/tex]
[tex]Median=\dfrac{7+1}{2}\text{th term}[/tex]
[tex]Median=\dfrac{8}{2}\text{th term}[/tex]
[tex]Median=4\text{th term}[/tex]
The 4th term from the arranged data set is 9.
[tex]Median=9[/tex]
Here, the most frequent number is 12 because it occurs 2 times. So, the mode of the data set is 12.
Therefore, the mean of the data set is 8.7143, median is 9 and mode is 12.
Amelia went shopping for a new camera because of a sale. The store was offering a 30% discount. What number should she multiply the prices on the tags by to find the price she would have to pay, before tax, in one step?
Amelia would have to multiply the number 7/10 on the price on the tags that she has to pay.
What is percentage?Percentage is a part of the whole number. It is denoted by % sign.
1 %= 1/100.
Given that,
The discount on new camera bought by Amelia = 30%.
To find the number that Amelia should multiply to pay,
Let The required number be x,
and total price of the camera is 100%
So after discount the price of camera = 100 - 30 = 70%
Implies that,
100 × x = 70
x = 70 / 100
x = 7 / 10
So the required number is 7/10 that Amelia should multiply the price she would have to pay.
