The probability of getting either 1 or 6 more than two times is P(T)=121/1296
To find the probability we use the binomial distribution.
Here we have 4 independent experiments. Each time, the sample space is (1,2,3,4,5,6) so the prob of getting a 6 is 1/6.
so p=1/6
prob of coming 6 and q= 1-p = 1-(1/6)=5/6
prob of not coming 6 is 5/6
p= prob of success. here our success event is getting 6
q= prob of failure. here our failure event is not getting 6
no of trials n=4
now using the binomial distribution formula:
ncr(p)^n(1-p)^r
here we want at least two 6, desirable outcomes are two 6 or three 6, or four 6 because at least two 6 doesn't mean that we can't get more than two 6 .
so r in these cases take the value of 2,3,4 respectively.
so for r=2
c(4,2)*(1/6)^2*(5/6)^2
P(A)= 150/1296
for r=3
c(4,3)*(1/6)^3*(5/6)^1
P(B)= 20/1296
for r = 4
c(4,4)*(1/6)^4*(5/6)^0
P(C)= 1/1296
here we will add these prob ..Getting two 6 fulfills our condition so we will stop and calculate the prob and keep it aside
now adding these we get P(T)=P(A)+P(B)+P(C).
(150/216) +(20/216) + (1/216)
P(T)= 171/1296

question 3 please answer
True: On the graph above, f(1) = 4.
How to calculate an equation of this line?Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:
y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
Where:
m represents the slope.x and y are the points.Next, we would determine the linear equation representing the line and passes through the points (-1, -2) and (1, 4) by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)
y - (-2) = (4 - (-2))/(1 - (-1))(x - (-1))
y + 2 = 6/2(x + 1)
y = 3(x + 1) - 2
y = 3x + 3 - 2
y = 3x + 1
When x = 1, the value of y is given by;

Nicholas works two part-time jobs in order to earn enough money to meet her obligations of $500 a week. His job in a restaurant pays him $10 an hour and his job in a hospital pays $25 an hour. He wants to work no more than 20 hours. Write the system of inequalities.
The system of inequality is 0 ≤ y ≤ 20.
Inequality in math is when two expressions, equations, or values are not equal to each other. Inequalities are represented by symbols such as "<" (less than), ">" (greater than), and "≠" (not equal to). Inequalities can be used to represent real-world situations where values or expressions can be greater than, less than, or not equal to each other. For example, the inequality “x > 5” means that x is greater than 5.
The system of inequalities that Nicholas needs to solve is:
10x + 25y ≤ 500
0 ≤ x ≤ 20
0 ≤ y ≤ 20
The first equation states that the total pay from both of his jobs must be less than or equal to $500. The second and third equations state that the number of hours he works at each job must be between 0 and 20.
Solving this system of inequalities will tell Nicholas how many hours he needs to work at each job in order to meet his obligations of $500 per week.

How many solutions does − 6y 13 9y 8y − 3 have?
The equation -6y + 13 + 9y + 8y - 3 has one solution when all the terms are combined.
This equation has one solution when all the terms are combined. To solve this equation, the first step is to combine like terms, which are terms that have the same variable and exponent. In this equation, there are two like terms, -6y and 9y, which can be combined to give us 3y. The next like terms are 13 and -3, which can be combined to give us 10. The final step is to group the coefficients and variable terms together and move the variable terms to one side of the equation and the coefficients to the other side. This gives us the equation 3y = 10, which can be solved by dividing both sides of the equation by 3. This gives us the solution y = 10/3.

If a1 = 4 and an = -2an-1 then find the value of a6.
The value of a₆ is -128, which matches the result we obtained using the recursive definition of the sequence.
What is meant by geometric?
A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value. Its general term is. aₙ= a₁ r⁽ⁿ⁻¹⁾. The value r is called the common ratio. It is found by taking any term in the sequence and dividing it by its preceding term.
The nth term of a geometric sequence is given as:
aₙ= a₁ r⁽ⁿ⁻¹⁾.
In which a1 is the first term.
For this problem, we have :
The first term is a1 = 4 and aₙ = -2aₙ₋₁.
Therefore, the common ratio is q = -2.
To solve the sequence using the geometric sequence formula, we need to first recognize that the sequence is a geometric sequence with a common ratio of -2.
a₁ = 4
a₂ = -2a₁ = -8 = 4 * (-2)
a₃ = -2a₂ = 16 = 4 * (-2)²
a₄ = -2a₃ = -32 = 4 * (-2)³
a₅ = -2a₄ = 64 = 4 * (-2)⁴
a₆ = -2a₅ = -128 = 4 * (-2)⁵
The formula for a geometric sequence is aₙ= a₁ r⁽ⁿ⁻¹⁾., where a is the first term, r is the common ratio, and n is the index of the term.
In this case, a=4 and r = -2, so the formula for the nth term is aₙ=4*(-2)⁽ⁿ⁻¹⁾.
To find a6, we substitute n = 6 into the formula:
a₆ = 4 * (-2)⁽⁶⁻¹⁾
= 4 * (-2)⁵
= -128
Therefore, the value of a₆ is -128, which matches the result we obtained using the recursive definition of the sequence.

Step-by-step explanation:
The blue line (or, more accurately, ray) r makes up the hypotenuse of a right triangle with legs (or sides) of lengths a and b. The relationship among the three values is given by the Pythagorean theorem, which states that for any right triangle, the sum of the squares of the lengths of the legs is always equal to the square of the length of the hypotenuse.
Thus, with a and b being the lengths of this right triangle and r being the hypotenuse, the length of the blue line r expressed in terms of a and b can be written as

What is the derivative of sin0?
The derivative of sin0 is cos0. We take the derivative of the inner function, which is 0, and then multiply it by the derivative of the outer function, which is the sine function. The derivative of the sine function is the cosine function.
The derivative of sinθ is cosθ.
When θ is 0, the derivative of sin0 is cos0.
The derivative of the sine function is the cosine function. This can be expressed mathematically as the derivative of sinθ equals cosθ. This means that the rate of change of the sine of an angle is equal to the cosine of that same angle. In other words, the derivative of sin0 is equal to cos0. To calculate the derivative of sin0, we can use the chain rule and the basic derivative rules. First, we identify the base function, which is sin0. Then, we differentiate the base function by applying the chain rule. We take the derivative of the inner function, which is 0, and then multiply it by the derivative of the outer function, which is the sine function.

Joe rides a bicycle in a straight line for 15 minutes with an average velocity of 9.0 m/s south, how far have they ridden.(convert 15 min into units of seconds)
Answer:We can use the formula:
Distance = Velocity x Time
To find out how far Joe has ridden on the bicycle.
First, we need to convert 15 minutes into seconds. 1 minute is equal to 60 seconds. So 15 minutes is equal to 15*60 = 900 seconds.
So the distance Joe has ridden is:
Distance = Velocity x Time
Distance = 9.0 m/s x 900 sec
Distance = 8100 meters.
Joe has ridden 8100 meters in a straight line for 15 minutes with an average velocity of 9.0 m/s south.

A shipping container will be used to transport several 50-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 27500 kilograms. Other shipments weighing 9500 kilograms have already been loaded into the container. Write and solve an inequality which can be used to determine xx, the number of 50-kilogram crates that can be loaded into the shipping container.
Answer: the maximum number of 50-kilogram crates that can be loaded into the shipping container is 360 crates.
Step-by-step explanation:
Let x be the number of 50-kilogram crates that can be loaded into the shipping container.
We can write an inequality to represent the maximum weight that can be loaded into the container:
x * 50 + 9500 <= 27500
To solve for x, we can first subtract 9500 from both sides:
x * 50 <= 18000
Then, we can divide both sides by 50 to find the number of crates that can be loaded:
x <= 360
So, the maximum number of 50-kilogram crates that can be loaded into the shipping container is 360 crates.

Now for the triangle! 12 x 10 is 120. Remember, if a question ever puts a number near that diagonal side (that does remain without a number near it now), it's trying to trick you. Only multiply the straight sides together.
For a triangle though, you would always divide the area by 2. A triangle is usually half of a square or rectangle. 120/2 = 60.
Now add 60 and 72 together to find the area of the full shape. That's 132. :)
Have a good night!
