Explanation:
Assuming a fair coin, the probability of getting tails is 1/2. The probability of getting three tails in a row is (1/2)^3 = (1/2)*(1/2)*(1/2) = 1/8
Put another way, there are 8 possible outcomes when flipping three coins. Those outcomes are:
HHHHHTHTHHTTTHHTHTTTHTTTWe see that only one occurrence of TTT shows up out of the eight possible outcomes; therefore, the probability of getting TTT is 1/8

el punto (4, -3) esta sobre el lado terminal del angulo 0 en posicion normal. hallar el valor de las seis razones trigonometricas de ese angulo
Answer:
Para un punto (x, y), el angulo generado entre el eje x y un rayo que conecta el origen de coordenadas con el punto es tal que:
Tan(θ) = y/x
Cos(θ) = x/(√(x^2 + y^2))
Sin(θ) = y/(√(x^2 + y^2))
Y las otras 3 relaciones trigonometricas son las inversas de las de arriba, entonces:
Ctg(θ) = x/y
Sec(θ) = √(x^2 + y^2)/x
Csc(θ) = √(x^2 + y^2)/y
En este caso tenemos el punto (4, -3), es decir:
x = 4
y = -3
Solo tenemos que reemplazar esos dos valores en las seis ecuaciones de arriba:
Tan(θ) = -3/4
Cos(θ) = 4/(√(4^2 + (-3)^2)) = 4/5
Sin(θ) = -3/(√(4^2 + (-3)^2)) = -3/5
Ctg(θ) = 4/(-3) = -4/3
Sec(θ) = √(4^2 + (-3)^2)/4 = 5/4
Csc(θ) = √(4^2 + (-3)^2)/-3 = 5/-3 = -5/3

Any number exponent 0.5 is a root of itself
find the area. Show formulas, work, and label your answer.
Answer:
34.1
Step-by-step explanation:
8 4/5 is not needed. The other two will given you the answer.
Area = 1/2 * b * h
b = 12 2/5 = 12.4
h = 5 1/2 = 5.5
Area = 1/2 * 12.4 * 5.5
Area = 34.1 square feet.
There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what sea is in simplest radical form
Answer:
C = 18
Step-by-step explanation:
There's a 90° triangle. The other two angles are 30° and 60°. The shortest line is nine the longest line is C. It's asking what is C is in simplest radical form
Solution:
A triangle is a shape with three sides and three angles. Types of triangle are right angled, isosceles, scalene, obtuse, acute.
The length of the side in a triangle is directly proportional to the opposite angle (angle facing the side).
A right angled triangle is a triangle with one angle equals to 90 degrees.
Since the shortest line is 9, the angle facing the shortest line is the smallest angle. The longest line is the hypotenuse which is given as C. Trigonometric identities shows the relationship between the sides of a triangle and its angles, hence:
sin30 = 9 / C
0.5 = 9 / C
C = 9/0.5
C = 18
Out of 60 people surveyed 42 respond yes to the server question what is the relative frequency of yes responses
Answer: 7/10
Step-by-step explanation:
Number of people surveyed = 60
Number of people who responded Yes = 42
The relative frequency will be the fraction of those who responded yes divided by the total people surveyed. This will be:
= 42/60
= 7/10.
The relative frequency is 7/10.
A . Describe a ray that can be found in the picture. Include a description of the difference between a raye and a line segment. Explain your answer using words and /or numbers
The angles formed by the lines that meet at each base are 90 degree angles and the distance between each base is the same.
Answer:
A ray is a a part of a line but a line segment is a line that connects two points
Step-by-step explanation:
A ray has one point at one end and an arrow that goes on forever, Though segments have 2 end points and do not go on forever.
"The angles formed by the lines that meet at each base are 90 degree angles and the distance between each base is the same."
was this your explanation? if so I think that it defines exactly the image shown on the quiz.

The diameter of a circle is 46 yards. What is the circle's circumference? d=46 yd Use 3.14 for n.
Answer:
144.44 yards
Step-by-step explanation:
The formula to find circumference is: C = π · d
Since we already have most of the factors figured out, we just replace them with what we have.
C = 3.14 · 46 yrds
144.44 = 3.14 · 46

Answer:
[tex](x - \frac{\sqrt{209} - 1}{8} )(x - \frac{-1 - \sqrt{209} }{8} )[/tex]
Step-by-step explanation:
FACTS TO KNOW BEFORE SOLVING :-
Quadratic Formula :-
Lets say , there's an equation ax² + bx + c.
[tex]=> x = \frac{-b + \sqrt{b^2 - 4ac} }{2a} \: or \: \frac{-b - \sqrt{b^2 - 4ac} }{2a}[/tex]
SOLUTION :-
According to the question ,
a (Coefficient of x²) = 4b (Coefficient of x) = 1c (constant) = -13By using quadratic formula ,
[tex]x = \frac{-1 + \sqrt{1^2 - 4 \times 4 \times (-13)} }{2 \times 4} \: or \: \frac{-1 - \sqrt{1^2 - 4 \times 4 \times (-13)} }{2 \times 4}[/tex]
[tex]=> x = \frac{-1 + \sqrt{209} }{8} \: or \: \frac{-1 - \sqrt{209} }{8}[/tex]
[tex]=> (x - \frac{\sqrt{209} - 1}{8} ) \: and \: (x - \frac{-1 - \sqrt{209} }{8} )[/tex] are the factors of 4x² + x - 13.
