The theoretical probability and experimental probability of spinning an odd number is equal to 5/9 and 2/3 respectively. The theoretical probability is less than the experimental probability of this event.
What is theoretical probability?Theoretical probability of an event is the ratio of number of favorable outcome to the total expected number of outcome of that event.
Vicky has a spinner divided into 9 equal sections that are labeled 1 though 9. There are total 5 odd terms. Thus, the theoretical probability of getting odd in ten spins is,
P=5/9
P=0.556
The data of spin 10 times is:
{2, 4, 1, 8, 7, 5, 3, 4, 1, 9}
Here, the odd numbers are 6. Thus, experimental probability of spinning an odd number is,
P=6/9
P=2/3
P=0.667
Thus, the theoretical probability and experimental probability of spinning an odd number is equal to 5/9 and 2/3 respectively. The theoretical probability is less than the experimental probability of this event.

Answer:
Perimeter = 90
Step-by-step explanation:
We're going to start with HI and go around the circle (and triangle, clockwise) see image. HI is 11. From H to G, then also has to be 11.
Subtract 26 - 11 to find LG. LG is 15.
If LG is 15, then LK is also 15. Subtract 34 - 15 to find JK.
JK is 19, so JI is also 19.
Two sides of the triangle are 34 and 26. The other side is 19+11=30.
Perimeter = 34+26+30
= 90
The volume of a tree stump can be modeled by considering it as a right cylinder. Justin measures its circumference as 84 in and its volume as 20214 cubic inches. Find the height of the stump in feet. Round your answer to the nearest tenth if necessary.
Given the values of the circumference and volume, the height of the tree trump to the nearest tenth is 36.0in.
What is a cylinder?A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.
The volume of a cylinder is expressed as;
V = π × r² × h
Where r is radius of the circular base, h is height and π is constant pi ( π = 3.14 )
Given the data in the question;
Circumference of the circular base C = 84inVolume of the cylinderical tree stump V = 20214in³First we determine the radius of the circular base.
Since circumference C = 2πr then r = C / 2π.
Hence, the volume of the cylinderical tree stump will be;
V = π × (C / 2π)² × h
V = π × ( C² / 4π² ) × h
V = hC² / 4π
4πV = hC²
h = 4πV / C²
We substitute our given values into the expression
h = ( 4 × 3.14 × 20214in³ ) / (84in)²
h = 253887.84in³ / 7056in²
h = 36.0in
Therefore, given the values of the circumference and volume, the height of the tree trump to the nearest tenth is 36.0in.

A square has a perimeter of 144. what is the length of each side?
[tex]~~~~~~~~\text{Perimeter of square} = 144\\\\\implies 4 \times \text{Side} = 144\\\\\implies \text{Side} = \dfrac{144}4\\\\\implies \text{Side} = 36\\\\\text{Hence the length of each side is 36 units.}[/tex]
Answer:
36
Step-by-step explanation:
In a Square,
perimeter (p) = 144
Length of side (L) = ?
we know,
p=4*L
144 = 4 *L
L = 144/4
L = 36
Since, All side of Square are equal . so,the length of each side is 36.

need help with all of these questions you see on the top. there the red squares. please someone smart. this is one of the problems I need to finish this tonight
Answer:
254.5 ft^3
Step-by-step explanation:
The volume of a cylinder is the area of the base times its height. To find the area of the base, since it is a circle, you would use the area formula of a circle([tex]\pi r^{2}[/tex] where r is the radius). So, the circle would have an area of 81 π. Now, multiplying this by the height, you get the volume. Since the height is just 1, the volume would be 81π which is 254.469004941. This rounded to the nearest tenth is 254.5.

HELP ME PLEASE !!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
C
Step-by-step explanation:
she wants to get information about the behavior of registered voters, but she surveys newspaper subscribers.
we have no clue, if they are registered voters.
if they are not, then the information does not apply.
if they are a mixture, then the survey mixed apples and oranges and does not provide usable information.
only if they all are also registered voters (which we don't know), this would provide some useful information.
but even in that last case I have to say she would have gotten information only about voters reading a specific newspaper. this particular newspaper might be one with especially short or long political commentaries. for better results the demographic sample population should cover multiple newspapers, or be newspaper independent (by picking the sample from voters registration lists instead of newspaper subscription lists).

Solve for x. Round to the nearest tenth, if necessary.
Answer:
x = 14
Step-by-step explanation.
First I would use sine to find x's value. So ----> sin(30) = 7/x ----> x sin(30) = 7 ----> x = 7/sin(30) = 14.
You Can also find that x is equal to 14 by applying the 30, 60, 90, triangle rule. Becuase '7' opposes the 30 degree angle it is 1/2 the hypotenuse, if thats the case just multiply the 7 by 2 and you have the hypotenuse length.

Cost price= $350 and selling price= $400. find the profit percent.
[tex]\large\boxed {Formula:Profit\% = \frac{(SP - CP)}{CP} \times 100}[/tex]
First, we'll have to deduct the cost price (350) from the selling price (400).
[tex]400 - 350[/tex]
[tex] = 50[/tex]
Now, we'll have to divide the deducted amount (50) by the cost price (350) and multiply by 100.
[tex] \frac{50}{350} \times 100[/tex]
[tex] = 14.28571429 \: \%[/tex]

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
At the local fair, the admission fee is $8.00 for an adult and $4.50 for a youth.
Let's suppose the number of admission of adults is x and for youth is y, then,
x + y = 209 ...(1)
8x + 4.50y = 1304.5 ...(2)
After solving the above two linear equation, we get:
x = 104
y = 105
Thus, the 104 adults and 105 youth admissions were purchased if the admission fee is $8.00 for an adult and $4.50 for a youth.

Part A
Answer: School BReason:
The range, IQR, and the standard deviation are all measures of spread.
IQR stands for Interquartile Range. Unfortunately your teacher made a typo and wrote IRQ by mistake.
The symbol [tex]\sigma[/tex] is the greek letter sigma used to represent the population standard deviation.
The smaller these measures are, the more less spread out the values will be. This leads to the most consistent data set. Think of it like being on an archery range. The more consistent shots are closely clustered around the same point (not necessarily the center), while the less consistent shots are more randomly scattered about.
School B has the smallest range, IQR, and standard deviation of the three schools. Therefore, this school has the most consistent attendance.
=============================================================
Part B
Answer: School CReason:
This school has the highest mean, and also the largest median, of all three schools. Both of these are measures of center or average. Compared to school B, this data set is a bit more spread out and not as consistent.
Select two ratios that are equivalent to 4:18.
Answer: The two ratios that are equivalent to 4:18 include 2:9 and 8:36
Step-by-step explanation:
To be able to solve this question, we've to simplify the given ratio. Therefore, 4:18 will be reduced to the lowest term and this will be:
= 4/18 = 2/9
Also, when 4/18 is multiplied by 2 for both the numerator and denominator, the value will be:
= 4×2/18×2
= 8/36
Therefore, the correct options will be B(2:9) and E(8:36).
it is easy.....
first, convert this ratio into a fraction
4 : 18 = 4/18
now , equivalent fractions
= 4 = 4 × 2 , 4 × 3
18 = 18 × 2 ,18 × 3
now answer
= 4/18 , 8/36 , 12/54
again covert into ratio
= 4:18 , 8:36 , 12:54

Answer:
a + (-c), b, c - (-b)
Step-by-step explanation:
First, identify the values of each point.
a = -1
b = 2
c = 3
Now, we can solve for the problems listed below the number line. We already know b = 2, so we don't need to solve for that one.
c - (-b) = 3 - (-2)
3 - (-2) = 3 + 2
= 5
--------------------------
a + (-c) = -1 + (-3)
-1 + (-3) = -1 -3
= -4
Now we can list the choices in order from least to greatest.
-4, 2, 5
