Dependent events: The likelihood of one event happening influences the likelihood of the other event happening.

When the result of one event affects the result of another, two events are said to be dependent events.

The likelihood of two connected events is the sum of the probabilities of the occurrences X and Y that happen after X.

The likelihood of one event does influence the likelihood of the other happening.

For instance, the likelihood of drawing another King decreases if you remove a King from a deck of cards without replacing it.

The x and y values that makes the relation a function are x = -4, y = 0, x = 5, y = -1 and x = 2, y = 8

The ordered pairs are given as

(− 3, 7), (–2, 3), (0, 8), (1, − 1), (x,y)

For a list of ordered pairs to represent a function, the following must be true

The x values must have exactly one y value

Using the above as a guide, we can see that x = -4, y = 0, x = 5, y = -1 and x = 2, y = 8 fits the above description

The (equivalent) compound annual rate at which Anders' salary has grown during the 12 years is 4.9%.

The compound annual rate is the equivalent rate of interest at which the present value of money grows to attain a future value.

At a 4.9% compound annual rate, Anders' salary has been growing by adding the growth amount to the initial salary and compounding both the principal and subsequent interest amounts until 12 years.

N (# of periods) = 12 years

PV (Present Value) = $2,800

PMT (Periodic Payment) = $0

FV = $-4,971.23

Results:

I/Y (Interest per year) = 4.9%

Total Interest = $2,171.23

Thus, using the online finance calculator, we can determine that Anders' salary has been compounded at 4.9% annually.

Explanation:

Total number of students = 28

75% of 28 = 75% × 28

= 0.75 × 28 = 21

This means 21 students have met their reading goal

Fraction of 28 students that met their reading goal = 21/28

Divide numerator and denominator by 7

Attaching the label:

I omitted the first label on both lines: it should be 0 and 0% respectively

The standard equation of a circle is given by:

where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.

Rewrite the equation as:

We can conclude it is a circle with center at (-3,-1) and radius of 4

Equation: h(t) = 96t - 16t²

h(t) = 96t - 16[tex]t^{2}[/tex]

Find the zeros of the given equation:

Factor out the greatest common factor (GCF)

h(t) = 8t (12 - 2t)

The two factors are:

0 = 8t

0 = 12 - 2t

For both factors, solve for t

8t = 0

8t/8 = 0/8

t = 0

12 - 2t = 0

-2t = -12

t = 6

Now we have the x-values (t) of our zeros:

t = 0

(0, 0)

t = 6

(6, 0)

The ball will land on the ground at 6 seconds

Recall that the maximum point of the graph is halfway between the two zeros:

6 + 0 = 6

6 ÷ 2 = 3

The ball will reach its maximum height in 3 seconds

To find this height, substitute t for 3 in the given equation, and solve for h:

t = 3

h(3) = 96(3) - 16(3)²

       = 288 - 16(9)

       = 288 - 144

       = 144

The maximum height the ball will reach is 144 feet

***Refer to the graph below to check your answer:

=======================================================

Explanation:

I'll use x in place of t

And use y in place of h(t)

The equation we have is y = 96x - 16x^2

This rearranges to y = -16x^2 + 96x

Compare this to y = ax^2+bx+c to find that

The x coordinate of the vertex is

h = -b/(2a)

h = -96/(2*(-16))

h = 3

Then plug this into the equation to find the value of y

y = -16x^2 + 96x

y = -16(3)^2 + 96(3)

y = 144

The y coordinate of the vertex is k = 144

The vertex is located at (h,k) = (3, 144) to represent the highest point of the parabola.

The max height of 144 feet occurs when the ball is in the air for 3 seconds.

Given that,

A 22-inch piece of steel is divided into three parts, the second of which is twice as long as the first and the third of which is one inch longer than the first.

We have to find the parts' lengths.

Let us take, the length of the first piece is x inch.

Then the length of the second piece is 2x.

Then the length of the third piece is 4x + 1 inch.

We know total length of the steel is 22 inch.

We can write as,

x + 2x + 4x + 1 = 22

7x = 21

x = 3.

Then, the length of the first piece is 3 inch.

Then the length of the second piece is 2×3=6 inch.

An equation of the quadratic function in standard form is equal to -2x² - 7x - 6 = 0.

A quadratic function can be defined as a mathematical expression (equation) that can be used to define and represent the relationship that exists between two or more variable on a graph.

In Mathematics, the standard form of a quadratic equation is given by;

ax² + bx + c = 0

y = f(x) = ax² + bx + c

Next, we would formulate a system of equations from the data contained in the table above:

-6 = a(-3)² + b(-3) + c  ⇒ -6 = 9a - 3b + c      .......equation 1.

0 = a(-2)² + b(-2) + c  ⇒   0 = 4a - 2b + c      .......equation 2.

-2 = a(-1)² + b(-1) + c  ⇒   -2 = a - b + c          .......equation 3.

From eqn. 2, we have:

c = -4a + 2b   .....equation 4.

Substituting eqn. 4 into eqn. 1 and 3, we have:

-2 = a - b - 4a + 2b          ⇒ -2 = -3a + b

-6 = 9a - 3b - 4a + 2b     ⇒ -6 = 5a - b

By using the elimination method, we have:

-8 = 2a

a = -4

For the value of b, we have:

-2 = -3a + b

b = -2 + 3a

b = -2 + 3(-4)

b = -2 - 12

b = -14

For the value of c, we have:

c = -4a + 2b

c = -4(-4) + 2(-14)

c = 16 - 28

c = -12.

Substituting the values of a, b and c into the standard form of a quadratic equation:

ax² + bx + c = 0

-4x² - 14x - 12 = 0

-2x² - 7x - 6 = 0
