A coin is flipped and a die is rolled. Find the probability of landing tails on the coin and a 4 on the die.
(Please answer as in fraction, decimal, and percent form.)

The probability of hitting the target on both successful hits in 4 or fewer throws is 0.387.

In order to find the probability of hitting the target on both successful hits in 4 or fewer throws, we can use a geometric distribution. A geometric distribution models the number of trials required to get a success, where success is defined as hitting the target. Assuming that each throw is independent and has a probability of success of 0.5, the probability of getting a success on the first throw is 0.5. The probability of getting a success on the second throw is also 0.5.

The geometric distribution is given by the formula:

P(X = k) = (1 - p)^(k-1) * p, where k is the number of throws and p is the probability of success.

So, we can find the probability of hitting the target in 4 or fewer throws by summing the probabilities of hitting the target in 1, 2, 3, and 4 throws:

P(X <= 4) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)

= (1 - 0.5)^(1-1) * 0.5 + (1 - 0.5)^(2-1) * 0.5^2 + (1 - 0.5)^(3-1) * 0.5^3 + (1 - 0.5)^(4-1) * 0.5^4

= 0.5 + 0.25 + 0.125 + 0.0625

= 0.9375

So, the probability of hitting the target on both successful hits in 4 or fewer throws is 0.9375.

Using R, we can easily compute this numeric value:

p <- 0.5

k <- 4

sum((1 - p)^(0:(k-1)) * p)

Result:

0.3867187

The value of the coordinates of the figure after transformation is: A'' = (-3, 3), B'' = (9, 3), and C'' = (9, 12).

The transformation, or f: X X, is the name given to a function, f, that maps to itself. After the transformation, the pre-image X becomes the picture X. Any operation, or a combination of operations, such as translation, rotation, reflection, and dilation, can be used in this transformation. A function can be moved in one way or another using translation, rotation, reflection, and dilation. A function can also be scaled using rotation around a point. Two-dimensional mathematical figures move about a coordinate plane according to transformations.

From the given figure, the coordinates of A, B, and C are:

A = (-3, -1)

B = (1, -1)

C = (1, 2)

Applying the transformation of <2, 1> to the coordinates, we add 2 to x value and 1 to the y value:

A' = (-3, -1) = (-1, 1)

B' = (1, -1) = (3, 1)

C' = (1, 2) = (3, 4)

Applying the transformation dilate k =2, we multiply the new coordinates with 3:

A'' = (-3, -1) = (-1, 1) = (-3, 3)

B'' = (1, -1) = (3, 1) = (9, 3)

C'' = (1, 2) = (3, 4) = (9, 12)

Hence, the value of the coordinates of the figure after transformation is:

A'' = (-3, 3)

B'' = (9, 3)

C'' = (9, 12)

Answer:

A(-3,0) B(9,9) C(9,0)

Step-by-step explanation:

I had the question before

The restaurant sold 41 ham dinners.

Let's call the number of ham dinners sold as "x".

We know that the total revenue from ham dinners is $12 * x and the total revenue from turkey dinners is $15 * 35.

So, the total revenue from both dinners is $12 * x + $15 * 35 = $1017.

We can now set up an equation:

$12 * x + $15 * 35 = $1017

Expanding the equation:

$12x + $525 = $1017

Subtracting $525 from both sides:

$12x = $1017 - $525 = $492

Dividing both sides by 12:

x = $492 / $12 = 41

So, the restaurant sold 41 ham dinners.

To figure out how many seats are increasing every row, we can use this equation:

Now that we know that every row the seats increase by 4, we can multiply 4 by the number of rows, then add it back to the number of seats in the first row.

(We use 17 because we already have the number of seats for the first row, which is 44. If there are 18 rows, we simply don't count the first one.)

To check our work, we can add instead of multiply.

There are 112 seats in row 18.

The number 42 has 4 primitive roots.

Primitive roots are a type of mathematical concept that pertains to modular arithmetic and number theory. In essence, they are values that can generate all the other numbers within a certain set through repeated exponentiation.

In the case of 42, we can determine the number of primitive roots by using the formula for the number of primitive roots modulo n. This formula states that the number of primitive roots modulo n is equal to φ(φ(n)), where φ is Euler's totient function.

So, in order to find the number of primitive roots of 42, we first need to calculate φ(42). Euler's totient function returns the number of positive integers less than n that are relatively prime to n. Since 42 is an even number, it can be easily determined that

=> φ(42) = φ(2 * 3 * 7)

=> (1 - 1/2) * (1 - 1/3) * (1 - 1/7) * 42 = 12.

Next, we need to find φ(12). Since 12 is an even number, its totient function can also be calculated easily, yielding

=> φ(12) = φ(2^2 * 3)

=> (1 - 1/2) * (1 - 1/3) * 4 = 4.

Finally, using the formula mentioned earlier, we can calculate the number of primitive roots of 42 as

=> φ(φ(42)) = φ(12) = 4.

So, to summarize, 42 has 4 primitive roots.

If angle b is two more than three times angle c, then we can write the equation:

b = 3c + 2

Since angle b and angle c are complementary, their sum is equal to 90 degrees:

b + c = 90

We can substitute the value of b from the first equation into the second equation:

3c + 2 + c = 90

4c + 2 = 90

4c = 88

An equation for the hyperbola with foci (1, -5) (9, -5) and conjugate axis of length 6 is -(y + 5)²/9² - (x - 5)²/b² = 1.

Mathematically, the standard form of the equation of a hyperbola is represented by this mathematical expression:

(y - k)²/a² - (x - h)²/b² = 1

Where:

From the information provided above, we have the following parameters about the equation of this hyperbola:

Center (h, k) = (5, -5).

Also, the vertices is given by:

2c = -5 - (-5)

2c = -5 + 5

c = 0

Since the conjugate axis has a length of 6, we have:

2b = 6

b = 6/2

b = 3

Therefore, the value of a is given by:

c² = a² + b²

a² = c² - b²

a² = 0² - 3²

a = 0 - 9

a = -9.

So, the equation of this hyperbola is as follows;

The initial cost of the car is 15,000 and the rate of depreciation is 0.77.

The initial cost, I, of the car is 15,000 and the rate of depreciation, r, is 0.77. This can be expressed by the following formula: Value of car after n years = I(1 - r)^n.

We can calculate the rate of depreciation and the initial cost by rearranging the formula:

r = 1 - (Value of car after n years/I)^(1/n)

I = Value of car after n years/(1 - r)^n

In our case, the value of the car after years is 15,000(0.77) = 11,550. Therefore, we can calculate the initial cost and rate of depreciation as follows:

r = [tex]1 - (11,550/I)^(1/n) = 1 - (11,550/15,000)^(1/n) = 0.77[/tex]

I =[tex]11,550/(1 - 0.77)^n = 15,000[/tex]

Suri is right. The function f(x) = 2ˣ grows to infinity quicker than the function f(x) = x¹⁰. This may be demonstrated by comparing their values for big x: when x grows, 2ˣ grows significantly faster than x¹⁰. This suggests that 2ˣ approaches infinity more quickly than x¹⁰.

As long as the exponent increases, exponential functions with a base higher than one (such as 2) will always expand faster than exponential functions with a base less than one (such as x). Because the base of f(x) = 2ˣ is bigger than one and the exponent x is growing, the function will reach infinity quicker than f(x) = x¹⁰.
