The theoretical probability of landing on tails is P = 0.5, and out of the 250 contestants, around 125 will win the game.
About how many contestants will win?
The coin has two possible outcomes, so if it is a fair coin, the probability for each of the outcomes will be 0.5 (this is the theoretical probability for a fair coin, where all the outcomes have the same probability).
Now, we know that a person wins if the coin lands tails up, and the probability of landing on tails is 0.5
Then, for a sample N, we can expect that about 0.5*N of the participants win.
In this case, the sample is 250, then we can expect that:
0.5*250 = 125
Around 125 of the contestants win the game

The expression that will make the algebraic equation true for all values of x is: A. 3x - 3.
What is a True Algebraic Equation?An algebraic equation is an equation where for a value of x, the right side and the left side of the equation must be balanced.
Given the algebraic equation, 15x - 15 = 5(?)
The missing expression, is 3x - 3, because:
15x - 15 = 5(3x - 3)
Open the bracket
15x - 15 = 15x - 15

Solve the system of equations using the substitution method Show all work,
y = 5x - 7
3x + 2y = 12
Answer: Since −3x does not contain the variable to solve for, move it to the right-hand side of the equation by adding 3x to both sides.
y=5x−7
−2y=3x−12
Divide each term in the equation by −2.

Albert has a rectangular print that is 1 foot in length and 8 inches in width. He wants to reduce the dimensions of the print proportionally so that the new print has a width of 3 inches. What should be the length of the new print?
Answer:
2.6 inches
Step-by-step explanation:
As shown in the title if length is x,
x * 1/x = 8/3 * x
8 * 1 = 3x
x = 8/3 in
= 2.6 in
The new length of the rectangular print will be 2.68 feet.
What is a rectangle?A rectangle is a geometrical figure in which opposite sides are equal.
The angle between any two consecutive sides will be 90 degrees.
Area of rectangle = length × width.
Perimeter of rectangle = 2( length + width).
Given a rectangular print with dimensions,
Length = 1 foot = 12 inches
Width = 8 inches.
Area = 12(8) = 96 square inches
Now,
The area of the new print should be the same
So,
96 = Length × 3
Length = 32 inches = 2.67 feet.
Hence "The new length of the rectangular print will be 2.68 feet".

There is 1/2 of the birds seen were either parrots or sparrows.
What is Rational number?A number which can be written in the form of fraction p / q , where q is non zero, are called Rational numbers.
Given that;
Figure shows the birds seen.
Now, We have;
By figure the half of circle is shown either parrots or sparrows.
Hence, The value of fraction of the birds seen were either parrots or sparrows is,
⇒ 1/2 of 100%
⇒ 1/2 × 100/100

For PQR, which one is equal to sin(P)?
Answer:
The third option.
[tex]cos(Q)=\frac{RQ}{PQ}[/tex]
Step-by-step explanation:
SIN is opposite over hypotenuse.
COS is adjacent over hypotenuse
Therefore
[tex]sin(P)=\frac{RQ}{PQ}[/tex]
Then we have 4 options.
It is not the first option beacause we can't determine which side is adjacent to the angle.
The second option
[tex]sin(Q)=\frac{RP}{QP}[/tex]
The third option
[tex]cos(Q)=\frac{RQ}{PQ}[/tex]
It is not the fourth option beacause we can't determine which side is opposite to the angle.
Finally we see that
[tex]cos(Q)=\frac{RQ}{PQ}[/tex]
and
[tex]sin(P)=\frac{RQ}{PQ}[/tex]
are equivalent.

Members of a softball team raised $1319.25 to go to a tournament. They rented a bus for $776.50 and budgeted $41.75 per player for meals. Write and solve an equation which can be used to determine pp, the number of players the team can bring to the tournament.
Answer:
13 players
Step-by-step explanation:
Money Raised=RentedBus+Meals
1319.25=776.50+41.75p (p is for the number of players)(Now we solve for x)
Subtract 776.50 from both sides: 542.75=41.75x
Divide both sides by 41.75: 13=x
Remember that x is for the number of players so there'll be 13 players going to the tournament.

Answer:
1/5
Step-by-step explanation:
It is easy to see a right triangle on each side of the original square with its hypotenuse on the side of the original square, each with an area of 2⋅A2=A. Thus the total area of the original square is 5A, or the ratio of the area of the shaded square to the original square is 1/5.

The water of the cylinder cannot fill the container, since the cylinder has less volume. Lastly, there is no apparent mistakes.
How to determine if two volumes are equivalent?The rectangular container ([tex]V_{R}[/tex]), in cubic inches, is full whether its volume is equal to the volume of the cylinder ([tex]V_{C}[/tex]), in cubic inches. The volume formulae for both containers are described below:
Rectangular container[tex]V_{R} = w\cdot l \cdot h[/tex] (1)
Where:
[tex]w[/tex] - Width, in inches[tex]l[/tex] - Length, in inches[tex]h[/tex] - Height, in inchesCylinder[tex]V_{C} = \pi\cdot r^{2}\cdot h[/tex] (2)
Where:
[tex]r[/tex] - Radius, in inches[tex]h[/tex] - Height, in inchesNow we proceed to determine the volume of each figure:
Rectangular container (w = 3.6 in, l = 3.6 in, h = 5.3 in)[tex]V_{R} = (3.6\,in)\cdot (3.6\,in)\cdot (5.3\,in)[/tex]
[tex]V_{R} = 68.688\,in^{3}[/tex]
Cylinder (r = 1.8 in, h = 5.3 in)[tex]V_{C} = \pi\cdot (1.8\,in)^{2}\cdot (5.3\,in)[/tex]
[tex]V_{C} \approx 53.947\,in^{3}[/tex]
The volume of the water in the cylinder is approximately 53.947 cubic inches. The water of the cylinder cannot fill the container, since the cylinder has less volume. Lastly, there is no apparent mistakes. [tex]\blacksquare[/tex]

Find the missing measurement using the given scale factor. B А scale factor from A to B = 1:7
Answer:
? = 49
Step-by-step explanation:
To solve this we just need to understand that when A=1, B=7. So when the side for a is 7 that is basically multiplying A by 7 so we have to do the same to the B side. So when the B side is multiplied by 7 it would be 7*7 =49 so the ? is equal to 49 when that similar side is equal to 7.
This is all based on the fact that the two triangles must be similar triangles.
Work out the size of one of the exterior angles
Given Information :-
⠀
A polygon with 10 sides ( Decagon )⠀
To Find :-
⠀
The value of one of the exterior angles⠀
Formula Used :-
⠀
[tex] \qquad \diamond \: \underline{ \boxed{ \pink{ \sf Exterior ~angle = \dfrac {360^\circ}{no. ~of~sides}}}} \: \star[/tex]
⠀
Solution :-
⠀
Putting the given values, we get,
⠀
[tex]\sf \dashrightarrow Exterior ~angle = \dfrac{360 ^\circ}{10} \: \: \\ \\ \\ \sf \dashrightarrow Exterior ~angle = \frac{36 \cancel{0}^\circ}{ \cancel{10}} \: \: \\ \\ \\ \sf \dashrightarrow Exterior ~angle = \underline{ \boxed{ \frak{ \red{36^\circ}}}} \: \star \\ \\ [/tex]
Thus, the value of the exterior angles of a Decagon is 36°.
⠀
[tex] \underline{ \rule{227pt}{2pt}} \\ \\ [/tex]
Answer:
36° .⠀
Explanation :
⠀
For a regular polygon of n sides, we have
[tex]{ \longrightarrow \qquad \pmb{ \it{Each \: exterior \: angle = { \bigg( {\dfrac{360}{n} } \bigg)^{ \circ} }}}}[/tex]
⠀
Here, We are to find the measure of each exterior angle of a regular decagon.
⠀
So, we know a regular decagon has 10 sides, so n = 10 .⠀
Now, substituting the value :
⠀
[tex]\sf \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = { \bigg( {\dfrac{360}{10} } \bigg)}^{ \circ} [/tex]
⠀
[tex]\sf \longrightarrow \qquad Each \: exterior \: angle _{(Decagon)}= { \bigg( {\dfrac{36 \cancel0}{1 \cancel0} } \bigg)}^{ \circ} [/tex]
⠀
[tex]\sf \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = { \bigg( {\dfrac{36}{1} } \bigg)}^{ \circ} [/tex]
⠀
[tex]{\pmb{ \frak{ \longrightarrow \qquad Each \: exterior \: angle_{(Decagon)} = 36^{ \circ} }}}[/tex]
⠀
Therefore,
The measure of each exterior angle of a regular decagon is 36° .A triangle has angle measures of 41 cm, and 24 cm. Find the measurement of the missing angle in the triangle.
