The probability of the total being equal to 8 is 1/9 or 11.11%.

To calculate this probability, we must first calculate all the possible combinations of two six-sided dice that add up to 8. Since both the dice are showing an even number, the possible combinations are (2, 6), (4, 4), and (6, 2). the total number of possible combinations for two six-sided dice is 36 (6 x 6). Therefore, the probability of the total being equal to 8 is 3/36 or 1/9 or 11.11%.

Since the base of the exponent is less than 1, then we have an exponential decay function, The decay rate can be obtained thus :

Hence, the decay rate is 28%

B.)

The amount of medication left in the body at 11 AM

f(5) = 75(0.72)⁵

f(5) = 14.5 mg

The amount left after 5 hours is 14.5 mg

C.)

15% of original amount = 0.15 * 75 = 11.25

substitute the value into the equation

\(11.25 = 75(0.72)^{t}\)

divide both sides by 75

\(0.15 = 0.72^{t}\)

t = log(0.15)/log(0.72)

t = 5.772

Hence, it will take 5.78 hours to have 15% of the original amount .

Answer:

C

Step-by-step explanation:

y=mx+b m=slope b=y-intercept, y-int: 4 slope: 3/1 but can just be put as 3. y=3x+4 bc it's a positive slope with a positive y-int.

The solution of the system of equations is the values of x and y that make both equations true at the same time. Therefore, the solution of the system of equations is (4, -12) and (-1, 2).

To find the solution, we can set the two equations equal to each other since they both equal y:
x2 - 5x - 8 = -2x - 4
Simplifying, we get:
x2 - 3x - 4 = 0
We can factor this quadratic equation to get:
(x - 4)(x + 1) = 0
This gives us two possible values for x: x = 4 or x = -1. To find the corresponding values of y, we can substitute each value of x back into one of the original equations:
If x = 4:
y = (4)2 - 5(4) - 8 = -12
So one solution is (4, -12).
If x = -1:
y = -2(-1) - 4 = 2
So the other solution is (-1, 2).

To find the solution of the system, we'll need to determine the point(s) where the two equations intersect. Here are the steps to solve the system:
1. Since both equations are equal to y, set them equal to each other:
x^2 - 5x - 8 = -2x - 4
2. Move all terms to one side of the equation to get a quadratic equation:
x^2 - 5x + 2x - 8 + 4 = 0
3. Simplify the equation:
x^2 - 3x - 4 = 0
4. Factor the quadratic equation:
(x - 4)(x + 1) = 0
5. Solve for x:
x - 4 = 0  =>  x = 4
x + 1 = 0  =>  x = -1
6. Substitute the x values back into either original equation to find the corresponding y values. We'll use the second equation, y = -2x - 4:
For x = 4: y = -2(4) - 4 = -8 - 4 = -12
For x = -1: y = -2(-1) - 4 = 2 - 4 = -2
7. Combine the x and y values to get the solutions:
(4, -12) and (-1, -2)
So, the solution of the system of equations is (4, -12) and (-1, -2).

To compute a heaviest Longest Increasing Subsequence (LIS) in a given sequence efficiently with a time complexity of O(n), we can use the concept of dynamic programming.

The algorithm follows these steps: 1. Initialize two arrays, "lis" and "sum," both of size n, where n is the length of the sequence. The "lis" array will store the length of the LIS ending at each element, and the "sum" array will store the maximum sum of the LIS ending at each element.

2. Initialize the "lis" and "sum" arrays with values of 1 and the corresponding element values of the sequence, respectively.

3. Traverse the sequence from left to right. For each element, compare it with all previous elements. If the current element is greater than the previous element and the sum of the LIS ending at the previous element plus the current element is greater than the sum at the current element, update the "lis" and "sum" arrays accordingly.

4. Finally, find the element in the "sum" array with the maximum value and trace back the LIS by following the indices stored in the "lis" array.

By following these steps, we can compute a heaviest LIS in linear time, O(n), where n is the length of the input sequence. The dynamic programming approach allows us to efficiently update and store the necessary information for calculating the maximum sum.

In a vector space V, a basis is a set of linearly independent vectors that span the entire vector space. Let's consider a basis B = {b1, b2, ..., bn} for vector space V.

The b-coordinate vectors of b1, b2, ..., bn represent the coordinates of these basis vectors with respect to the basis B. In other words, they represent how each basis vector can be expressed as a linear combination of the basis vectors in B.

Now, let's consider the standard basis for an n-dimensional vector space, which consists of the n column vectors e1, e2, ..., en of the n×n identity matrix. Each column vector ei has a 1 in the ith position and 0s in all other positions.

To show that the b-coordinate vectors of b1, b2, ..., bn are the columns e1, e2, ..., en of the n×n identity matrix, we need to demonstrate two key properties:

Linear Independence: The basis vectors b1, b2, ..., bn are linearly independent, which means no vector in the set can be written as a linear combination of the other vectors. Similarly, the column vectors e1, e2, ..., en of the identity matrix are linearly independent.

Spanning: The basis vectors b1, b2, ..., bn span the entire vector space V, which means any vector in V can be expressed as a linear combination of the basis vectors. Similarly, the column vectors e1, e2, ..., en of the identity matrix span the n-dimensional space.

Since both sets of vectors satisfy these properties, it follows that the b-coordinate vectors of b1, b2, ..., bn are indeed the columns e1, e2, ..., en of the n×n identity matrix.

The probability that either the first or second car is defective can be found by calculating the probability that at least one of the selected cars is defective.

To find the probability that either the first or second car is defective, we can use the principle of complementary probability. The complementary probability is the probability that an event does not occur.

The probability that neither the first nor the second car is defective is equal to the probability that both selected cars are non-defective.

Since the cars are selected without replacement, the probability of selecting a non-defective car first is (13/20) because there are 13 non-defective cars left out of 20 total cars.

After the first non-defective car is selected, there are 19 cars remaining, out of which 6 are defective. Therefore, the probability of selecting a non-defective car second is (13/19).

To find the probability that either the first or second car is defective, we subtract the probability of selecting two non-defective cars from 1 (since the sum of probabilities for all possible outcomes must be 1):

P(either first or second car is defective) = 1 - P(both cars are non-defective)

= 1 - (13/20) * (13/19)

= 1 - (169/380)

= 211/380

Therefore, the probability that either the first or second car is defective is 211/380.

2n^3 + 3n + 10 can be written as a polynomial of the form Q(n^3), where Q(n^3) represents the set of polynomials of the form a(n^3).

To prove that the expression 2n^3 + 3n + 10 is in the set Q(n^3), where Q(n^3) represents the set of polynomials of the form a(n^3), we need to show that the expression can be written in the form a(n^3) for some constant "a".

Let's start by factoring out the common factor of n^3 from each term:

2n^3 + 3n + 10 = n^3(2 + 3/n^2 + 10/n^3)

Now, let's rewrite the expression as a single term multiplied by n^3:

2n^3 + 3n + 10 = (2 + 3/n^2 + 10/n^3)n^3

Simplifying the expression inside the parentheses:

= (2n^3 + 3n^2 + 10n^3)/n^3

= (12n^3 + 3n^2)/n^3

= 12 + 3/n

ow, we can see that the expression can be written in the form a(n^3), where a = 12 and n^3 = 3/n.

Therefore, we have shown that 2n^3 + 3n + 10 can be written as a polynomial of the form Q(n^3), where Q(n^3) represents the set of polynomials of the form a(n^3).

The term is called an identity element. In multiplication, the identity element is one because any number multiplied by one results in the same number. In addition, the identity element is zero because any number added to zero results in the same number.

The term in mathematics for the operation or number that leaves others unchanged when combined with them is called the identity element.

It is also known by the name of neutral element.

In multiplication, the identity element is one (1) because when you multiply a number by one the result remains the same as the original number. For any number a,

a1=1a=a.

While in addition, the identity element is zero (0) because when you add zero to a number, the result remains the same as the original number. For any number a,

a+0=0+a=a.

There is no identity element for subtraction, and division only has an identity element for certain sets.

Step-by-step explanation:

=4(-8x + 5) – (-33x – 26)

=-32x+20+33x+26

=-32x+33x+20+26

=1x+46 is the answer

hope it will help :)

Answer:

x+46

Step-by-step explanation:

4(-8x + 5) – (-33x – 26) ​

The first step is to distribute and simplify.

4 distributed to -8x will be -32x, and same thing goes with 5, which is 20.

-

The first part of the equation is -32x+20

Now, this is where it gets confusing.

If there is a sign before a pair of parentheses, you always put 1. In this case, it's -1 distributed to -33x and -26.

So, the second part of the expression will be +33x+26

The whole expression is

-32x + 20 + 33x + 26

add like terms, -32x+33x= x.

20+26=46.

The answer is x+46.
