Answer:
a. False
b. False
Step-by-step explanation:
a. The experimental probability or relative frequency is based on actual results from an experiment and may differ from the theoretical probability of an event occurring.
This statement is false because, both the experimental and theoretical probability must agree for the probability of the event occurring to the true.
If both do not agree, that means we have two different probabilities for a s ingle event, which cannot be true. So, the statement is false.
b. The Experimental Probability will be almost the same as the Theoretical Probability as the number of trials of an experiment is very small
This statement is also false because, the experimental and theoretical probabilities only agree when the number of trials of an experiment become large. For small number of trials, both the experimental and theoretical probabilities might not agree.

What is the solution to the equation?
Answer:
Step-by-step explanation:
[tex]\sqrt[3]{x+4}+\sqrt[3]{2x +8}=0\\\\\sqrt[3]{x+4}= -\sqrt[3]{2x + 8}\\\\(x +4)^{\frac{1}{3}}=-(2x+8)^{\frac{1}{3}}\\\\[/tex]
Take cube,
[tex][(x+4)^{\frac{1}{3}}]^{3} =- [(2x +8)^{\frac{1}{3}}^{3}]\\\\(x+4)^{3*\frac{1}{3}}=-(2x + 8)^{3*\frac{1}{3}}\\\\[/tex]
x + 4 = - (2x + 8)
x +4 = 2x *(-1) + 8 *(-1)
x+ 4 = -2x - 8
x +2x+4 = - 8
3x + 4 = - 8
3x = - 8 -4
3x = -12
x = -12/3
x = -4
4x - 9y = -23
3x - 7y = -17

Use the long division method to find the result when 6x^3+17x^2+19x+28 is divided by 3x+7.
Answer:
2x^2 + x + 4
Step-by-step explanation:
Use Polynomial division.
The value after divide will be;
⇒ 2x² + x + 4
What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The expression is,
⇒ 6x³ + 17x² + 19x + 28 ÷ (3x + 7)
Now,
Since, The expression is,
⇒ 6x³ + 17x² + 19x + 28 ÷ (3x + 7)
Divide the expression as;
⇒ 3x + 7 ) 6x³ + 17x² + 19x + 28 ( 2x² + x + 4
6x³ + 14x²
- -
----------------------
3x² + 19x
3x² + 7x
- -
--------------------
12x + 28
12x + 28
- -
-------------------
0
Thus, The solution is,
⇒ 6x³ + 17x² + 19x + 28 ÷ (3x + 7) = (2x² + x + 4)

A house cast 65-foot shadow. A person standing nearby cast 7.2 foot shadow. Their height is 4.8 feet. What is the height of the house?
Answer:
42.43 feets
Step-by-step explanation:
Given :
(Height of house / shadow of house) = (height of person / shadow of person)
(height of house / 65) = (4.8 / 7.2)
Cross multiply
Height of house * 7.2 = 4.7 * 65
Height of house = 305.5 / 7.2
Height of house = 42.43 feets

find the value of angel 0 to the nearest 10th
Answer: 36.9
Step-by-step explanation:
For this question you have to find out whether you are using Sin, Cos or Tan.
To work out which one you are using you can use SOH CAH TOA to help you.
SOH- The 'S' is for Sin, the 'O' and the 'H' is for Opposite over Hypotenuse.
CAH- The 'C' is for Cos and the 'A' and the 'H' is for Adjacent over Hypotenuse.
TOA- The 'T' is for Tan, the 'O' and the 'A is for Opposite over Adjacent.
As you have the Opposite (the side opposite the angle we're looking for) and the Adjacent (the side next to the angle were looking for) we would be using Tan.
So first you would have to write:
Tanθ=3/4
Then because we want Theta (θ) on it's own we would have to do the inverse to 'undo' the equation. Tan-1 is the inverse of Tan.
θ=Tan-1 3/4
To find the answer you would have to put it in your calculator.
θ=36.9

Triangle 1 has vertices at (A,B), (C,D), and (E,F). Triangle 2 has vertices at (A+1,B+3), (C+1,D+3), and (E+1,F+3). What can you conclude about triangle 2?
Given:
Triangle 1 has vertices at (A,B), (C,D), and (E,F).
Triangle 2 has vertices at (A+1,B+3), (C+1,D+3), and (E+1,F+3).
To find:
The conclusion about the triangle 2.
Solution:
From the given information it is clear that the x-coordinates of the vertices of triangle 2 are 1 more than the x-coordinates of the vertices of triangle 1.
Similarly, the y-coordinates of the vertices of triangle 2 are 3 more than the y-coordinates of the vertices of triangle 1.
So, the rule of translation is:
[tex](x,y)\to (x+1,y+3)[/tex]
It means the triangle 1 is shifted 1 unit right and 3 units up to get the triangle 2.
Therefore, triangle 2 is congruent to triangle 1 and triangle 2 is the translation of triangle 1 by 1 unit right and 3 units up.
You buy a car for $25000. It lose 14% of its value every year. Sally wrote a function that represents the value of the car after t years. V(t)=25000(1.14)t Describe and correct the error
Answer:
Correct answer
V(t) = 25000(0.86) t
Step-by-step explanation:
You wont turn 14% into a multiplier (1.14 - multiplier) becuase the value decreases not increases so you do 100% - 14% to get 86% and divide by 100 to get 0.86...that's the value that goes in the brackets

Answer:
72.25
Step-by-step explanation:
12.5 x 8.5 = 106.25
5 x 6.75 = 33.75
106.25- 33.75 = 72.25
Answer: H
Step-by-step explanation:
You're tryna find the area of the wall
Which is the whole surface area minus the door's area
Whole surface area = 8.5 x 12.5 = 106.25
Door area = 5 x 6.75 = 33.75
106.25-33.75 = 72.5 ft^2

tan30° = [tex]\frac{\sqrt{3} }{3}[/tex] , then
tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{7}[/tex] = [tex]\frac{\sqrt{3} }{3}[/tex] ( cross- multiply )

A triangular garden has angles of 80, 50, and 50. If the longest side is 40 feet, what is the length of the remaining sides?
Answer:
the other two sides are 31.11 feet and 31.11 feet
Step-by-step explanation:
since two angles are 50°, the triangle is isosceles with the other two sides being equal in length.
A right triangle is formed by a line from its peak down & perpendicular to
the 40 foot side. It's hypotenuse is the unknown (x) and it's base is 40/2 = 20 feet.
cos 50 = 20/x
0.6428 = 20/x
x = 31.11 feet

what multiple of 9 is a factor of 9
Answer:
9
Step-by-step explanation:
Answer:
( 1 ), ( 3 ), ( 9 )
Step-by-step explanation:
Every time you add one to a digit (which is the same as adding 10, 100, 1000, etc) you get a number that is one more than a multiple of 9, so you have to subtract one from the number, which brings the sum of the digits back to 9.
Can someone check my answers to see if they are correct please? They are on the 2nd page. Thank you!

Yes, all your answers are correct.
They are correctly matched with their reasons.
Write how you would explain the following problem using the order of operations to a 5th grader?
2 + (9-6) x 5 / 3
(PLS make a big paragraph thanks)
Answer:
PEMDAS
Step-by-step explanation:
Use PEMDAS. Parenthesis, Exponents, Multiplication/Division, Addition/Subtraction.
Start with your parenthesis, which is (9-6). This comes out to 3. Your equation should now look like 2+(3)x5/3
Then, go to your exponents. Since we don't have any, we skip this step.
Now, we look from left to right for any multiplication symbols or division symbols. Finding (3)x5, this comes out to 15. Now rewrite your equation, if should look like this: 2+15/3.
Repeat the last step and find your division symbol, and find this 15/3. That comes out to 5.
The last step is finding addition or subtraction symbols, and since there's only two numbers left we can just solve the problem from here.
2+5=7.
