To assign the sum of extra credit received to the total extra credit, you need to follow these steps:

1. Make a list of all the test grades, and mark the ones that have extra credit with a "+" sign. For example, if the test scores are: 95, 110+, 80, 120+, 100, you would mark the 110+ and the 120+.

2. Add up all the extra credit marks. In this example, that would be 110 + 120 = 230.

3. Count the number of extra credit marks. In this example, there are two.

4. Multiply the number of extra credit marks by the maximum extra credit value. If full credit is 100, then the maximum extra credit value is the amount that a student can exceed the maximum score by. In this case, that would be 20 (since 120 - 100 = 20). So, 2 x 20 = 40.

5. Add the extra credit value to the total score. In this example, the total score is 505 (95 + 110 + 80 + 120 + 100). So, you would add 40 to that to get 545.

Therefore, the answer is: To assign sum extra with the total extra credit received given list test grades, you need to add the extra credit value to the total score by multiplying the number of extra credit marks by the maximum extra credit value, and then adding that value to the total score.

The area of the triangle determined by the points P(1, 1, 1), Q(-4, -3, -6), and R(6, 10, -9) is approximately 51.61 square units.

To find the area of the triangle determined by the points P(1, 1, 1), Q(-4, -3, -6), and R(6, 10, -9), we can follow these steps:

1. Calculate the vectors PQ and PR by subtracting the coordinates of P from Q and R, respectively.

2. Find the cross product of PQ and PR.

3. Calculate the magnitude of the cross product.

4. Divide the magnitude by 2 to find the area of the triangle.

Step 1: Calculate PQ and PR

PQ = Q - P = (-4 - 1, -3 - 1, -6 - 1) = (-5, -4, -7)

PR = R - P = (6 - 1, 10 - 1, -9 - 1) = (5, 9, -10)

Step 2: Find the cross product of PQ and PR

PQ x PR = ( (-4 * -10) - (-7 * 9), (-7 * 5) - (-10 * -5), (-5 * 9) - (-4 * 5) ) = ( 36 + 63, 35 - 50, -45 + 20 ) = (99, -15, -25)

Step 3: Calculate the magnitude of the cross product

|PQ x PR| = √( (99)² + (-15)² + (-25)² ) = √( 9801 + 225 + 625 ) = √(10651)

Step 4: Divide the magnitude by 2 to find the area of the triangle

Area = 0.5 * |PQ x PR| = 0.5 * √(10651) ≈ 51.61

So, the area of the triangle determined by the points P(1, 1, 1), Q(-4, -3, -6), and R(6, 10, -9) is approximately 51.61 square units.

To produce g, function was reflected over the x-axis and | shifted up 3 units . Function g can be defined as g(x)=f(x-1)+4.

What is axis ?

An axis is a straight line around which an object or a geometric shape can rotate or be symmetrical. In a coordinate system, an axis is a line that serves as a reference for the location of points in space.

When a function f(x) is reflected over the x-axis, it changes the sign of the y-coordinate values. By reflecting the graph of f(x) over the x-axis, the new function g(x) will have the same shape as f(x) but with all y-coordinate values inverted.

Additionally, by shifting the function up 3 units, it means that the y-coordinate values of the new function g(x) will be 3 units greater than the y-coordinate values of the original function f(x).

So the transformation can be represented as:

g(x) = f(x-1) + 4

It is the horizontal shift of 1 unit to the right, and a vertical shift of 3 units up

The Intermediate Value Theorem concludes that for a continuous function on a closed interval, if there are two points in the interval such that the function takes on two different values, then there must be at least one point in the interval where the function takes on every value between those two values.

Assuming its assumptions are met, the Intermediate Value Theorem (IVT) concludes that:

If a continuous function, f(x), is defined on a closed interval [a, b], and k is any value between f(a) and f(b), then there exists at least one value c in the interval (a, b) such that f(c) = k.

In other words, if a function is continuous on a closed interval and k is a value between the function's values at the endpoints of the interval, the function must take on the value k at least once within that interval. This theorem is particularly useful in determining the existence of roots or zeroes for a function in a specified interval.

There were 3,200 bacteria present.

A colony of bacteria grown under ideal conditions in a laboratory so that the population increases exponentially with time. At the end of 3 hours, there are 10,000 bacteria. At the end of 5 hours, there are 62,500 bacteria.

The exponential growth of a population of bacteria is given by the formula:N = Noert,

where N is the final population size, No is the initial population size, r is the growth rate, and t is the time in hours.

The growth rate : r = (ln N - ln No) / t

Using the given data, we can write two equations in two unknowns (No and r):10,000 = Noer3100 = Noer5

Dividing the second equation by the first equation gives: 100/62.5 = e^(r*2)

Taking the natural logarithm of both sides gives:ln(100/62.5) = r*2r = ln(100/62.5) / 2r = 0.0995

Using the growth rate r, we can solve for the initial population No using either of the two original equations:No = 10,000 / e^(r*3)No = 10,000 / e^(0.0995*3)No = 3,200 bacteria

Let x be the full price of each Mighty Mare toy pony.

During the holiday sale, Pamela purchased each toy at $3 less than its full price. Therefore, the price she paid during the sale was:

x - $3

Since she bought 4 of these toys, her total cost during the sale was:

4(x - $3)

We also know that Pamela paid a total of $52 during the sale. Therefore, we can set up an equation:

4(x - $3) = $52

Simplifying this equation, we get:

4x - $12 = $52

Adding $12 to both sides, we get:

4x = $64

Dividing both sides by 4, we get:

x = $16

Therefore, each Mighty Mare toy pony costs $16 at full price.

Let's assume that the full price of each Mighty Mare toy pony is x dollars. Since Pamela purchased 4 Mighty Mare toy ponies, each at $3 less than its full price, the cost of each toy pony during the sale would be (x - 3) dollars.

To find the equation that represents this situation, we can set up the equation based on the given information:

4 * (x - 3) = 52

In this equation, 4 represents the number of Mighty Mare toy ponies purchased, (x - 3) represents the cost of each toy pony during the sale, and 52 represents the total amount paid by Pamela.

By solving this equation, we can determine the value of x, which represents the full price of each Mighty Mare toy pony.

Step-by-step explanation:

Answer:

Step-by-step explanation:

We can use FOIL (front outer inner last)

First terms 4x * x = 4x^2

Outer terms 4x * 5 = 20x

Inner terms -3 * x = -3x

Last terms -3 * 5 = -15

we put all of these together

4x^2 + 20x - 3x - 15, which simplifies to

4x^2 + 17x - 15

The simplified expression is 4x^2 + 17x - 15

To simplify the expression:  (4x-3)(x+5)

we can use the distributive property.

Multiplying each term in the first binomial (4x-3) by each term in the second binomial (x+5), we get

4x^2 + 20x - 3x - 15.

Combining like terms, we simplify further to obtain

4x^2 + 17x - 15.

Thus, the simplified expression is 4x^2 + 17x - 15,

which is the result of multiplying (4x-3) and (x+5) together using the distributive property.

One of the following statements that is true is the probability that an event does not occur is equal to 1 minus the probability the event does occur (Option B)

Probability is a mathematical concept that attempts to quantify randomness.

A probability is a number between 0 and 1 that quantifies the likelihood of a certain event or set of events occurring.

The probability of an event happening is determined by dividing the number of ways the event can happen by the total number of outcomes possible.

The probability that an event does not occur is equal to 1 minus the probability the event does occur.

Step-by-step explanation:

first you cross multiply then you pay attention in class.

The square root of 25/16 = 1.20, and the set of numbers that contain the square root of 25/16 are 1 < x < 2.

Any integer's square root equals that same number, which, when squared, yields the original number.

Let's assume that m is a positive integer, and that √m.m = m.

A square root function is a one-to-one function in mathematics that receives a positive integer as an input and outputs the square root of that number.

Given that the number is 25/16.

Taking the square root of the individual values, that is numerator and denominator we have:

√25 / √16 = 5/4 = 1.20

Hence, the square root of 25/16 = 1.20, and the set of numbers that contain the square root of 25/16 are 1 < x < 2.
