Answer:
Theoretical probability is based upon what is expected when rolling two dice, as seen in the "sum" table at the right. The theoretical probability of rolling an 8 is 5 times out of 36 rolls. The theoretical probability = 5/36 ≈ 13.9%. 3) The experiment rolled more 8's than would be expected theoretically.
Step-by-step explanation:
The theoretical probability of not rolling a 2 is 5/6.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
Assuming a fair six-sided die, the probability of rolling a 2 is 1/6.
Therefore, the probability of not rolling a 2 on a single roll of the die is:
P(not rolling a 2) = 1 - P(rolling a 2) = 1 - 1/6 = 5/6
Thus,
The theoretical probability of not rolling a 2 is 5/6.

Answer:
60 days
Step-by-step explanation:
The least common multiple of 6, 4, and 10 is the product of the unique factors ...
6 = 2·3
4 = 2²
10 = 2·5
The LCM is 2²·3·5 = 60.
All of them will meet at the swimming pool again in 60 days.

In a certain isosceles triangle, the base is 1 1/2 times as long as each leg and the perimeter is 63. How long is the base?
Answer:
The base is 27 units long.
Step-by-step explanation:
This is a solve the system question. Call the length of the base B and the length of each leg L. We are told:
[tex]B=1.5L[/tex]
and
[tex]B+2L=63[/tex]
Sub the first equation into the second:
[tex]1.5L+2L=63\\3.5L=63\\L=18[/tex]
Now that we have the leg length, sub that into either of the original equations to find the base. I'll use the first equation:
[tex]B=1.5(18)\\B=27[/tex]
Morgan has 5 blue t-shirts , 3 green t-shirts and 2 red t-shirts . She randomly picks a shirt. What is the probability of choosing each color?
Answer:
Confusing question but I think it's 10:10
Step-by-step explanation:
Total outcome = 5:3:2
= 5+3+2
=10.
Probability = number of success
Total outcome
= 10/10
Therefore the probability of Morgan choosing each colour is 10:10.
Your bill at a restaurant is $35.00. There is an 8% meals tax (sales tax). How much is the tax? You want to leave a 20% tip. You should calculate the tip on the $35.00 (not the cost after the tax). How much is the tip? What is the total bill?
Answer:
$44.8
Step-by-step explanation:
The tip:
35*0.2=$7
The total bill:
35*8% = 35*0.08 = 2.8
35 + 2.8 +7 = 44.8
(I added 35 for the price of the actual lunch, and the 7 for the tip)
Alternatively, you can just add the 8% and the 20% and the 100% (for the lunch itself), and then multiply the $35.
8%+20%+100%=0.08+0.2+1= 1.28
1.28*35=$44.8

7/3
Step-by-step explanation:
To get the answer, we add all of the numerator numbers together since the denominators are all the same. 3 + 4 + 7 = 7 + 7 = 14
The answer is 14/6. We can then simplify it and divide both the numerator and the denominator by 2. That gives us 7/3 and that is our final answer.

Angie has a square dog pen with a perimeter of 20 meters. She wants to put a diagonal piece of fencing inside her pen to cut it in half because her 2 dogs have been fighting. How long of a piece of fencing will she need to buy? Hint: The formula for finding the hypotenuse of a right triangle is: a² + b² = c²
Answer: 7.07 miles
Step-by-step explanation:
Hi, to answer this, first, we have to find the length of the square dog pen.
Perimeter of a square = 4 x sides
Replacing with the value given:
20 = 4 s
Solving for s:
20/4=s
Side = 5 meters
Since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (in this case length of the diagonal) and a and b are the other sides.
Replacing with the values given:
c^2 = 5^2 + 5^2
c^2 = 25+25
c^2 = 50
c = √50
c = 7.07 miles

Which functions have the same rate of change?
y=0.3x-6
y=3x-8
y=0.3x+4
y=0.03x+1
1:A and D
2:B and C
3:A and C
4:C and D
Answer:
Option 3
Step-by-step explanation:
All equations are in slope-intercept form. [tex]y=mx+b[/tex]
The 'm' is the slope.
The 'b' is the y-intercept.
The slope is also known as the rate of change. So, we would have to look at what replaces 'm' and select two equations that have the same rate of change.
Let's look over the equations:
Equation A:[tex]y=0.3x-6[/tex]
In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.
Equation B:[tex]y=3x-8[/tex]
In this equation, 3 replaces 'm', so the rate of change for this equation is 3.
Equation C:[tex]y=0.3x+4[/tex]In this equation, 0.3 replaces 'm', so the rate of change for this equation is 0.3.
Equation D:[tex]y=0.03x+1[/tex]In this equation, 0.03 replaces 'm', so the rate of change for this equation is 0.03.
Equation C and equation A have 0.3 as the slope. Since the question asks for two equations that have the same rate of change, the answer would be Equations A and C, or Option 3.

Total pens = 22
Total clips = 30
Probability of red pen = 0
Because there are no red pens
Probability of white clip = 16/30 = 8/15
Define dot product, inner product, cross product.
Answer:
Dot product. ... In Euclidean geometry, the dot product of the Cartesian coordinates of two vectors is widely used and often called "the" inner product (or rarely projection product) of Euclidean space even though it is not the only inner product that can be defined on Euclidean space; see also inner product space.
Step-by-step explanation:
Answer:
- A dot product is the product of the magnitude of the vectors and the cos of the angle between them.
- A cross product is the product of the magnitude of the vectors and the sine of the angle that they subtend on each other.
- An inner product is a generalization of the dot product.
Step-by-step explanation:
Dot product - the sum of the products of the corresponding entries of the two sequences of numbers. Geometrically, it is the product of the Euclidean magnitudes of the two vectors and the cosine of the angle between them. These definitions are equivalent when using Cartesian coordinates.
Cross Product - The cross product is a mathematical operation which can be done between two three-dimensional vectors. It is often represented by the symbol. After performing the cross product, a new vector is formed. The cross product of two vectors is always perpendicular to both of the vectors which were "crossed".
Inner product - In a vector space, it is a way to multiply vectors together, with the result of this multiplication being a scalar.

Tom has to take three medicines each day. One is to be taken
every 3 hours, one every 4 hours and one just four times a day.
He takes his first dose on Monday at 9am, what is the next time he
takes all three medicines together?
Please help
Answer:
9pm Monday
Step-by-step explanation:
It would take 12 hours, that would be when all of the medicines would be taken at the same time, because 3/4/6 are factors of 12
Answer:
Monday at 9pm
Step-by-step explanation:
The first drug is by every 9,12,3,and 6.The second drug is by every 9,1,and 5.While the third drug is by every 9 and 3.Therefore, 9 is common so the next time the drugs will be taken at the same time is by 9pm.

Step-by-step explanation:
I did it on paper.
Answer:
A.) 8x^2 + 18x + 36
Step-by-step explanation:
Use these steps to see how exactly I arrived at my answer!
[tex]=8x^3+2x^2-72\\=2\cdot \:4x^3+2x^2-2\cdot \:36\\=2\left(4x^3+x^2-36\right)\\[/tex]
[tex]=4x^3+x^2-36\\=\left(x-2\right)\frac{4x^3+x^2-36}{x-2}\\=4x^2+\frac{9x^2-36}{x-2}\\=4x^2+9x+\frac{18x-36}{x-2}\\=4x^2+9x+18[/tex]
[tex]=2\left(x-2\right)\left(4x^2+9x+18\right)\\=\frac{2\left(x-2\right)\left(4x^2+9x+18\right)}{x-2}[/tex]
Between these steps, I canceled out a common factor!
[tex]=2\left(4x^2+9x+18\right)\\= 8x^2+18x+36[/tex]
Explain how to find the median.
Answer:
The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
Step-by-step explanation:
have a great day
There are two ways to find the median, depending on what situation it is.
The first, is to simply arrange the number set into proper numerical format (least to greatest), then count from both sides towards the middle to find the median or middle number.
The latter, is when we have a number set that has an equal amount of numbers. For this, we would again, arrange it into proper numerical format, and the count from both sides up. However, there will be two numbers at the middle. So, what we do, is that we have to add them up and then divide by 2 since there are only those two numbers at the middle. Once, the numbers are added up and divided by 2, you will get the resulting median.
Example: Find the median of the data set below.
1,2,3,4,5,6,7,8,9,9
There are 10 numbers in this data set.
It's already been arranged into proper numerical format.
So, all we have to do is, find the two middle numbers and then add them up and divide.
The two numbers at the middle are: 5 and 6.
Add them up.
5 + 6 = 11
Divide by 2.
11/2 = 5.5
Thus, the median of the data set is 5.5
