Events A and B are dependent, because P(A)≠P(B|A). The correct option is A.

From the information, the experiment consists of rolling a standard six-sided die once. Event A is "rolling a 5 and event B is "rolling an odd number."

Events A and B are dependent because the outcome of event A (rolling a 5) affects the probability of event B (rolling an odd number). The probability of rolling a 5 is 1/6, while the probability of rolling an odd number given that you have already rolled a 5 is 0. The probability of rolling an odd number is 1/2, and thus P(A) ≠ P(B|A)

In simple terms, Events A and B are dependent because outcome of event A affects the probability of event B happening.

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant.

The correct expression to represent this situation through inequality is "p + n ≥ 17"

In mathematics, inequalities are mathematical expressions that compare two values without using the symbol = (equal). Instead, in inequalities, one value is greater than, less than, etc. Due to this, the most common symbols used to write an inequality are:

< = This means less than

> = This means greater than

≥ = This means equal or greater than

≤ = This means equal or less than

Considering, the amoung of pennies and nickels is minimum 17, the correct symbol to use is ≥, which means the amoung of coins is either 17 or more than 70. Moreover, the letters p and n can be used to represent the pennies and nickels. Based on this, the correct expression is:

Sure, here is a more casual and friendly way to explain how to calculate the weighted dollar amount of the savings account:

"Hey there! To find out the weighted dollar amount of the savings account, you just need to do a little math. First, multiply the amount invested in the savings account by the return on investment (ROR). Then, divide that number by the total ROR for all investments.

So, if you have $2,700 invested in the savings account and it has an ROR of 3.6%, the weighted dollar amount of the savings account would be:

($2,700 * 3.6%) / (3.6% + 1.8% + 13.6% - 1.2%) = $104.04

98,329.16 is the Growing Ordinary Annuity's Future Value (FV). Given a predetermined rate of return or discount rate, the present value of an annuity is the entire cash worth of all of your future annuity payments.

A sequence of equal-spaced payments constitutes an annuity. There are a lot of real-world examples of financial transactions involving annuities, including. • an automobile loan with a set repayment schedule of equal monthly payments.

Calculating the present value of an annuity is done by multiplying the dollar amount of each payment by the following formula:[tex]P = PMT \times [1- [ (1 / 1+r)^n] / r][/tex]  where P is the present value of your annuity stream. PMT is short for payment method type.

A set of periodic payments that will be received in the future at the start of each period or at its conclusion is referred to as a "annuity." The formula used to determine annuity payments and annuities due is based on the PV of annuities due, the effective interest rate, and the number of periods.

The relationship between the slopes of the parallel sides is m₁ = m₂.

The relationship between the lengths of the non-parallel sides is perpendicular or intersecting.

The slope of a line can be calculated by taking the tangent ratio of the angle formed by it with the x axis.

The angle between two parallel lines is zero.

This implies that they form same angle with the x-axis.

The slopes of two parallel lines are always equal to each other.

Since, the slope of a line is the tangent of the angle made by it with x axis.

Then, it can be written as m₁ = m₂.

The paper company shipped 10 small boxes and 8 large boxes.

An equation is an expression that shows the relationship between two or more numbers and variables.

Let x represent the number of small boxes shipped and y represent the number of large boxes shipped.

Each small box of paper weighs 30 pounds and each large box of paper weighs 75 pounds.

A total of 18 boxes of paper were shipped, hence:

x + y = 18

y = 18 - x    (1)

Also, they weighed 900 pounds, hence:

30x + 75y = 900

but y = 18 - x, hence:

30x + 75(18 - x) = 900

30x - 75x + 1350 = 900

x = 10

y = 18 - x = 18 - 10 = 8

There are approximately 13.38 ounces of chips in the bag.

What is division?

Division is one of the four basic mathematical operations of arithmetic, along with addition, subtraction, and multiplication. It is the inverse operation of multiplication, and it is used to find out how many times one number is contained within another number.

To find out how many ounces of chips are in the bag, you can use the formula:

cost of bag / cost per ounce = number of ounces

In this case, you know that the cost of the bag is $3.91 and the cost per ounce of chips is 29.5 cents per ounce.

First, you need to convert the cost per ounce from cents to dollars. 29.5 cents is equal to 0.295 dollars (29.5 cents / 100 cents = 0.295 dollars)

So, you can substitute these values into the formula:

3.91 / 0.295 = 13.38

Hence, there are approximately 13.38 ounces of chips in the bag.

The integral of f(x) on the interval [0, 6] is equal to 8.

Here we have the graph of f(x), and we want to find the integral:

[tex]\int\limits^6_0 {f(x)} \, dx[/tex]

Remember that the integral is the area under the curve, so we only need to find the areas of the "blocks" on the image.

Betwen 0 and 2 we can see that f(x) = 2, there the area is:

A = 2*(2 - 0) = 4

Between 2 and 4 we have f(x) = -3, then:

A' = -3*(4 - 2) = -3*2 = -6

And between 4 and 6 we have f(x) = 5, then:

A'' = 5*(6 -4) = 5*2 = 10

According to this postulate, two triangles are congruent if their two angles and included sides are congruent with each other.

If the sides and angles of one triangle are the same as the sides and angles of another triangle, then two or more triangles are said to be congruent. Three postulates—ASA (angle-side-angle), SAS (side-angle-side), and SSS—that are demonstrated in the lesson can also be used to assess for congruency.

If, for example, triangle ABC has a hypotenuse of 5 cm and a leg of 4 cm and triangle PQR has a hypotenuse of 5 cm and a leg of 4 cm, then these two triangles have the same dimensions and, according to the HL theorem, are congruent to one another.

Triangle congruence can be implied in some situations by SSA, but not always. It differs from the other triangle congruence postulates/criteria because of this.

By function composition, f(x) and g(x) are inverse functions

A function is a relationship between inputs where each input is related to exactly one output.

f(x)= ∛(x-1) and g(x)=x³+1

To confirm the inverse relationship using composition.

If f(g(x)) = g(f(x)) then they are inverse functions

Let's confirm:

f(g(x)) = f(∛(x³+1))

         = ( ∛((x³+1)-1 )

        = ∛(x³)

       = x

g(x)=x³+1

g(f(x)) = g(∛(x-1) )

        = (∛(x-1))³ + 1

        = x-1+1

        = x

Since  f(g(x)) = g(f(x)) then they are inverse functions
