You flip a coin, and then roll a number cube twice. (a number cube 1-6) Find the probability of the event.
1) Flipping head, rolling a 5, and rolling a 2
2) Flipping tails, rolling an odd number, and rolling a 4
3) Flipping head, not rolling a 2, and rolling an even number
Answer:
1) 1.4%
2) 8.3%
3) 20.8%
Step-by-step explanation:
Alrighty! You are looking at some compound probability problems.
The trick with these is to figure out the probability of each piece of an event, and then multiply those together to get the overall probability.
Quick note about notation: p(event A) is short hand for saying "The probability of event A is....."
1) Flipping head, rolling a 5, and rolling a 2
P(flipping heads) = 1/2
p(rolling a 5) = 1/6
p(rolling a 2) = 1/6
so: (1/2) x (1/6) x (1/6) = 1/72 or about 1.4%
2) Flipping tails, rolling an odd number, and rolling a 4
p(flipping tails) = 1/2
p(rolling an odd number) = 3/6
p(rolling a 4) = 1/6
so: (1/2) x (3/6) x (1/6) = 3/72 or about 8.3%
3) Flipping head, not rolling a 2, and rolling an even number
p(flipping heads) = 1/2
p(not rolling a 2) = 5/6
p(rolling and even number) = 3/6
so: (1/2) x (5/6) x (3/6) = 15/72 or about 20.8%

The distance from the tether ball pole to the edge of the circle is 5 feet what is the circumference of the circle ?
Answer:
31.416
Step-by-step explanation:
2 times Pi (3.14) times the radius (5)
The radius into the formula gives a circumference of 10π feet.
The circumference of a circle can be calculated using the formula:
Circumference = 2 x π x radius
Given that the radius of the circle is 5 feet, we can substitute this value into the formula to find the circumference:
Circumference = 2 x π x 5 = 10π feet
Therefore, the circumference of the circle is 10π feet.

Which matrix represents the system of equations shown below? 3x-5y=12 4x-2y=15
Answer:
[tex]\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right][/tex]
Step-by-step explanation:
When making a matrix of two equations with the variables x and y, the result will be a matrix with three columns:
a column for the values of x in each equationa column for the values of y in each equationa column for the independent values of each equationsince our system of equations is:
[tex]3x-5y=12\\ 4x-2y=15[/tex]
we can see that the value for x in the first equation is 3 and in the second equation is 4, thus the first column will have the numbers 3 and 4:
[tex]\left[\begin{array}{ccc}3&&\\4&&\\\end{array}\right][/tex]
Now for the values of y we hvae -5 in the first equation and -2 in the second equation, we update the matrix with another column with the values of -5 and -2:
[tex]\left[\begin{array}{ccc}3&-5&\\4&-2&\\\end{array}\right][/tex]
Finally, the last column is the independent values of each equation (or the results) in the first equation that number is 12 and in the second equation is 15, thus the matrix is:
[tex]\left[\begin{array}{ccc}3&-5&12\\4&-2&15\\\end{array}\right][/tex]
usually there is a line separating the columns for the values of x and y, and the independent values:
[tex]\left[\begin{array}{ccc}3&-5 &|12\\4&-2 &|15\\\end{array}\right][/tex]
this is the matrix of the system of equations
If 37% of high school students said that the excercise regularly, find the
probability that 5 randomly selected students will say thay they exercise
regularly. Answer as a percent with a % sign and no spaces or a decimal.
Convert your decimal to a % first and then round to the nearest thoudandth. If
leaving it in decimal form, round to the nearest hundred-thousandths.
The required probability is 0.687% or 0.6867.
Given Probability:
The probability that a single student exercises regularly is 37%, or 0.37.
Probability for Independent Events:
Since the events are independent events (each student's response does not influence another's), multiply the individual probabilities together. For 5 students, the calculation is :
[tex]Probability\ that\ 5\ randomly\ selected\ students\ will\ say\ thay\ they\ exercise\ regularly = P(5) = 0.37^5[/tex]
Calculation:
[tex]P(5) = 0.37^5 \approx 0.006867[/tex]
Converting to Percent:
To convert this decimal to a percentage, multiplying by 100:
[tex]0.006867 \times 100 \approx 0.6867 \%[/tex]
Rounding:
Finally, rounding to the nearest thousandth:
Probability = 0.687%
So, the probability that 5 randomly selected students will say they exercise regularly is approximately 0.687%.

Step-by-step explanation:create the triangle or add angel Q+R=?then Q+S=? then see what has greater vaule1. Find the exact value for area of the triangle with the side lengths 5, 9, and 10.
Answer:
area = 6[tex]\sqrt{14}[/tex] units²
Step-by-step explanation:
Given the 3 sides of a triangle, we can use Hero's formula to calculate the area (A)
A = [tex]\sqrt{s(s-a)(s-b(s-c)}[/tex]
where s s the semi perimeter and a, b , c the sides of the triangle
let a = 5, b = 9 and c = 10
s = [tex]\frac{a+b+c}{2}[/tex] = [tex]\frac{5+9+10}{2}[/tex] = [tex]\frac{24}{2}[/tex] = 12
A = [tex]\sqrt{12(12-5)(12-9)(12-10)}[/tex]
= [tex]\sqrt{12(7)(3)(2)}[/tex]
= [tex]\sqrt{504}[/tex]
= [tex]\sqrt{36(14)}[/tex]
= 6[tex]\sqrt{14}[/tex] units²
Answer:
Step-by-step explanation:
a = 5 units ; b = 9units ; c = 10 units
Semi perimeter = (a+b+c)/2 = (5+9+10)/2 = 24/2 = 12 units
s-a = 12 -5 = 7 units
s -b = 12 - 9 = 3 units
s-c = 12- 10 =2 units
[tex]Area=\sqrt{s*(s-a)(s-b)(s-c)}\\\\=\sqrt{12*7*3*2}\\\\=\sqrt{2*2*3*7*3*2}\\\\=2*3\sqrt{2*7}\\\\=6\sqrt{14}\\[/tex]

101 f12
110 112
202112

Answer:
Area of the regular octagon is approximately 102ft²Step-by-step explanation:
Given the radius and length of a side of regular octagon as shown;
radius = 6ft and length of side = 4.6ft
Area of a regular octagon is expressed as [tex]A = 2(1+\sqrt{2} )a^{2}[/tex] where a is the length of one side. Given a = 4.6ft
Area = [tex]A = 2(1+\sqrt{2} )(4.6)^{2}\\[/tex]
[tex]= 2(1+\sqrt{2} )*21.16\\= (2+2\sqrt{2})*21.16\\ = 4.83*21.16\\= 102.20ft^{2} \\[/tex]
Area of the regular octagon is approximately 102ft²
The approximate area of a regular octagon with a radius of 6 ft and a side length of 4.6 ft is about 110 ft², found using the area formula for regular polygons.
To approximate the area of a regular octagon, one can break it down into triangles or use a formula. In this case, let's use the formula for the area of a regular polygon, which is: A = (1/2) × Perimeter × Apothem. The apothem can be found using trigonometry since we have a regular octagon, or we could calculate the area as eight identical isosceles triangles, where each triangle's area is (1/2) × base × height.
The student has provided that the side length (s) is 4.6 ft. For a regular octagon, we have 8 such sides. Therefore, the perimeter (P) is P = 8s = 8 imes 4.6 ft = 36.8 ft. Assuming the radius given is the apothem, we can directly calculate the area using the formula:
A = (1/2) × P × Apothem = (1/2) × 36.8 ft × 6 ft = 110.4 ft².
The approximate area of the octagon is therefore about 110 ft², after rounding off to the nearest whole number (due to the significant figures rule).
What is the slope of the line given by the equation below? y = - 3x + 5
Answer:
-3
Step-by-step explanation:
As per the given equation, the slope of the line is -3.
In mathematics, the slope of a line is a fundamental concept that describes the steepness or incline of the line. It measures how much the y-coordinate changes relative to the corresponding change in the x-coordinate. The slope is represented by the coefficient of the x-term in the equation of the line, when it is written in slope-intercept form
(y = mx + b).
The given equation is y = -3x + 5. Here, -3 is the coefficient of the x-term, which is the slope of the line. Since the equation is already in slope-intercept form (y = mx + b), we can directly identify the slope as -3.
A slope of -3 means that for every 1 unit increase in the x-coordinate, the y-coordinate decreases by 3 units. Conversely, for every 1 unit decrease in the x-coordinate, the y-coordinate increases by 3 units. The negative sign indicates that the line is decreasing from left to right, sloping downwards.

In a triangle RSM, the measure of angle SRM is twice the measure of angle RSM. A point O is selected on side RS such that SO=SM. The length of the angle bisector of angle RMS equals RO. What is the degree measure of angle RSM. The answer is a positive integer.
Final answer:
The measure of angle RSM is calculated to be 45 degrees.
Explanation:
The problem involves a triangle RSM where angle SRM is twice the measure of angle RSM, and a point O on side RS such that SO=SM.
Given that the length of the angle bisector of angle RMS equals RO, we seek to determine the measure of angle RSM.
Since the problem is based on the properties of triangles and angle bisectors, and it does not provide enough information to use standard geometric methods, we infer that the triangle RSM must be an isosceles triangle.
This is because SO=SM, which implies that angles RSM and RMS are equal.
Since SRM is twice RSM and the sum of angles in a triangle is 180 degrees, we can set up the equation
2x + x + x = 180,
where x is the measure of angle RSM.
Solving, we get 4x = 180, so x = 45 degrees.
Therefore, the measure of angle RSM is 45 degrees.

Answer:
When x is 4, y = 29
Step-by-step explanation:
the equation y = 5 + 6x, states that y equals 5 + 6 TIMES whatever x is.
So if x = 4, then you can substitute x in the equation to get this:
Y = 5 + 6(4) - substitute x with 4
Y = 5 + 24 - multiply 6 by 4 [6 + 6 + 6 + 6 = 6 x 4]
Y = 5 + 24 - add 5 and 24 together
Y = 29 - 5 + 24 = 29
Therefore, Y = 29
