Answer:
Relative frequency is defined as the number of "desired" results divided by the total number of possible results. Experimental probability is defined the same way. This means that the first choice is best, the experimental probability and relative frequency are the same.
The theoretical probability, on the other hand, would be 0.5, or 300/600, which is larger than the experimental probability.

(check image)
Answer:
Step-by-step explanation:
sin(0) = 0/2
sin(30) = 1/2
sin(45) = [tex]\sqrt{2}[/tex]/2
sin(60) = [tex]\sqrt{3}[/tex]/2
sin(90) = [tex]\sqrt{4}[/tex]/2
cos(90) = 0/2
cos(60) = 1/2
cos(45) = [tex]\sqrt{2}[/tex]/2
cos(30) = [tex]\sqrt{3}[/tex]/2
cos(0) = [tex]\sqrt{4}[/tex]/2
notice that sin and cos repeat, but in reverse

The diameter of a monster truck tire is 6 feet. If the truck tire makes 12 revolutions, how far did the truck travel?
Answer:
About 207 inches
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = πd . . . . . where d represents the diameter
The circumference of the tire is the distance the truck will move when the tire makes one revolution. That distance is ...
C ≈ 3.1416×(66 in) ≈ 207.35
The truck will travel about 207 inches for each revolution of the tire.
inverse operation needed
Answer:
it is C.

option A.
Step-by-step explanation:
we have
[tex] \frac{4\pi \sqrt{5} - 2\pi \sqrt{5} }{3 \sqrt{5} } [/tex]
taking out 2[tex] \pi\sqrt{5}[/tex] common from the numerator

Dave sold 60 general and reserved tickets for a concert. He sold general tickets for $10 each and reserved tickets for $15 each collecting a total of $725. Write a system of equations to determine the number of tickets he sold at each price and solve your system of equations?
Answer:
The system is of equations is:
[tex]\left\{ \begin{array}{ll} 10g+15r=725 & \quad \\ g+r=60 & \quad \end{array} \right.[/tex]
Where g is the amount of general tickets and r is the amount of reserve tickets.
35 general tickets and 25 reserve tickets were sold.
Step-by-step explanation:
Let general tickets be represented by g and reserved tickets be represented by r.
Each general ticket sells for $10 each and reserved tickets $15 each. Dave collected a total of $725. Thus:
[tex]10g+15r=725[/tex]
And a total of 60 tickets were sold. Hence:
[tex]g+r=60[/tex]
Our system of equations is:
[tex]\left\{ \begin{array}{ll} 10g+15r=725 & \quad \\ g+r=60 & \quad \end{array} \right.[/tex]
We can solve by substitution. First, divide both sides of the first equation by 5:
[tex]2g+3r=145[/tex]
Next, we can subtract a variable (r in this case) from the second equation:
[tex]g=60-r[/tex]
Substitute:
[tex]2(60-r)+3r=145[/tex]
Distribute:
[tex]120-2r+3r=145[/tex]
Simplify:
[tex]120+r=145[/tex]
Subtract:
[tex]r=25[/tex]
Using the previous equation:
[tex]g=60-r[/tex]
Substitute and evaluate:
[tex]g=60-(25)=35[/tex]
So, 35 general tickets and 25 reserve tickets were sold.

victor is selling lemonade to raise money for his school the amount of money he collected from his sales each day is summarized on the box plot below
The interquartile range of Victor's lemonade sale is A = 7
What in Interquartile Range ( IQR )?The distance between the upper and lower quartiles is known as the interquartile range. Half of the interquartile range corresponds to the semi-interquartile range. Finding the values of the quartiles in a small data set is straightforward.
The spread of the data, or statistical dispersion, is measured by the interquartile range. The middle 50%, fourth spread, or H-spread are further names for the IQR. It is described as the spread between the data's 75th and 25th percentiles.
Given data ,
Let the interquartile range of sales of Victor's lemonade be A
Now , the equation will be
Let the 75th percentile data = 29
Let the 25th percentile data be = 22
Now , the IQR is calculated by spread between the data's 75th and 25th percentiles
On simplifying , we get
The IQR = 29 - 22 = 7
Hence , the interquartile range is 7

Answer:
all of the brackets first
Answer:
Step-by-step explanation:
Those consecutive angles must sum to 180 degrees.
7x+9+7y-4=180
7x+7y+5=180
7x+7y=175
x+y=25
x=25-y
We also have
11x-1+2y+5=180
11x+2y+4=180
11x+2y=176, using x=25-y that we found above makes this
11(25-y)+2y=176
275-11y+2y=176
-9y+275=176
-9y=-99
y=11, and since x=25-y
x=25-11
x=14
Finally
z+7x+9=180
z+7x=171
z=171-7x, we found that x=14 earlier so
z=171-7(14)
z=171-98
z=73
So the three values are
x=14, y=11, and z=73 degrees.

The question tells you how to work it: use the relations you studied.
Here, you have the power of an expression with an exponent. The exponents multiply.
[tex]\text{Rule: }(a^b)^c=a^{bc}\\\\\text{Appication: }(b^3)^2=b^{3\cdot2}=\boxed{b^6}[/tex]
_____
Additional comment
A coefficient is used to indicate repeated addition: 3x = x + x + x.
An exponent is used to indicate repeated multiplication: x³ = x·x·x.
This is still true when the exponent is applied to an expression with an exponent:
(b³)² = (b³)(b³) . . . . the factor b³ is repeated 2 times as indicated by the exponent 2
Of course, each of these indicates repeated multiplication, so we really have ...
(b³)(b³) = (b·b·b)·(b·b·b) = b·b·b·b·b·b
And this can be simplified using an exponent to show the repeated multiplication:
= b⁶
Then, by going the long way around, we arrive at ...
(b³)² = b⁶

Using the method of proof by contradiction, prove that if a product of two positive real numbers is greater than 1,000,000, then at least one of the numbers is greater than 1000.
Step-by-step explanation:
To prove - Using the method of proof by contradiction, prove that if
a product of two positive real numbers is greater than
1,000,000, then at least one of the numbers is greater
than 1000.
Proof -
For a proof of contradiction , firstly we have to assume that the statement is not true.
Here given statement is - A product of two positive real numbers is greater than 1,000,000.
Let if possible, there does not exist 2 +ve integer real number such that at least one of the numbers is greater than 1000.
⇒both the number are in between 0 to 1000
Let a and b are 2 +ve real numbers.
⇒ab < 1000×1000
⇒ab < 1000000
As given,
ab > 1000000
Contradiction.
Hence proved.
If a product of two positive real numbers is greater than 1,000,000, then at least one of the numbers is greater than 1000.
Select the graph that correctly represents ƒ(x) = –2(x + 4)2 – 1.Find the equation of the parabola with its focus at (3,4) and its directrix y = 0.
Answer:
Equation of parabola: 8*(y - 2) = (x - 3)^2
or
y = (1/8)*(x - 3)^2 + 2
Step-by-step explanation:
focus at (3,4) and its directrix y = 0.
Focus equation: (h, k + c) = (3, 4)
Directrix equation y = k - c = 0
so h = 3, k + c = 4, k - c = 0
Solve the system : k + c = 4 and k - c = 0
add the equations together: k + c + k - c = 4 + 0
2k = 4
k = 2
so k + c = 4, 2 + c = 4, c = 2
4c (y - k) = (x - h)^2
4*2 *(y - 2) = (x - 3)^2
8*(y - 2) = (x - 3)^2
