Michelle invests $1000 at a bank offering 3% compounded quarterly.

Answers

Answer:

A = 1000(1 + .03 /4)4t

Explanation:

The money invested is the principal that is $ 1000.

The quarterly interest = 3/4 = 0.75 %

Assuming the number of years the money invested was x, then the interest period (n) will be 4 x (quarters)

Using the formula, A = P (1 + r/100)∧n

Therefore, the growth of the investment will be given by

1000( 1.0075)∧n, where n is the interest period.

Of the last 20 contestants on a game show, 8 won a prize what is the experimental probability that the next contestant will win a prize?

Answers

Answer:

2/5

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Experimental probability is based on the result of an experiment that has been carried out multiples times

probability that the next contestant will win a prize = number of contestants that won in the last games / total number of contestants in the last games

What is the volume of a ball if the radius of the ball is 15 inches? Leave your answer in terms of Pi.
13,500pi in3
20pi in3
3375pi in3
4500pi in3​

Answers

Answer:

[tex]V=4500\pi\ in^3[/tex]

Step-by-step explanation:

Given that,

The radius of a ball, r = 15 inches

We need to find the volume of a ball. The ball is in the shape of a sphere. The formula for the volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Put all the values,

[tex]V=\dfrac{4}{3}\pi \times (15)^3\\\\V=4500\pi\ in^3[/tex]

So, the volume of the ball is equal to [tex]4500\pi\ in^3[/tex].

The solution of this trigonometric identity is [tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex].

Step-by-step explanation:

Let [tex]7\cdot \tan \theta - 8 = 5\cdot \tan \theta -5[/tex], we proceed to simplify the expression and solve afterwards either by algebraic or by trigonometric means:

[tex]7\cdot \tan \theta -8 = 5\cdot \tan \theta -5[/tex]

[tex]2\cdot \tan \theta = 3[/tex]

[tex]\tan \theta = \frac{3}{2}[/tex]

[tex]\theta = \tan^{-1} \frac{3}{2}[/tex]

The tangent is a trigonometric function with a period of 180°. Hence, we find that the family of angles associated with such value is:

[tex]\theta = 56.310^{\circ} \pm 180\cdot i ^{\circ}[/tex], [tex]\forall \,i\in \mathbb{N}_{O}[/tex]

PLEASE HELP The diameter D of a sphere is 19 m. Calculate the sphere's surface area A.
Use the value 3.14 for at, and round your answer to the nearest tenth.

Answers

Answer:

A = 1,133.5 m³

Step-by-step explanation:

Surface area of a sphere, A = 4πr²

π = 3.14

Radius, r = diameter / 2

= 19 m / 2

= 9.5 m

Surface area of a sphere, A = 4πr²

A = 4 * 3.14 * (9.5)²

= 4 * 3.14 * 90.25

= 1,133.54

A = 1,133.54 m³

To the nearest tenth

A = 1,133.5 m³

What is the relationship between the number of sides of the base of a prism and the number of lateral faces? The number of sides of the base of a prism is less than the number of lateral faces. The number of sides of the base of a prism and the number of lateral faces is equal. The number of sides of the base of a prism is greater than the number of lateral faces. There is no consistent relationship between the number of sides of the base of a prism and the number of lateral faces.

Answers

Answer:

Every prism has as many faces, and edges, as its base has sides. Thus, a prism with an octagonal (eight sided) base has eight lateral faces, and eight lateral edges. Each lateral face meets two other lateral faces, as well as the two bases. As a consequence, each lateral face is a four sided polygon.

The number of sides of the base of a prism and the number of lateral faces is equal.

What is a prism?

A prism is a three-dimensional object with two congruent and parallel faces, called the bases and it encloses the space between the bases. Every cross-section parallel to the base of a prism is congruent to its base.

How do we solve the given question?

In the question, we are asked to tell the relationship between the number of sides of the base of a prism and the number of lateral faces.

We let the number of sides of the base of the prism be s, and let the number of lateral faces of the prism be f.

We know that a prism has two parallel and congruent bases and every corresponding side of the base are connected by a pane. These planes are the lateral faces of the prisms. As each corresponding pair of sides is connected by one lateral face, the number of the lateral face is equal to the number of sides of the base.

∴ The number of sides of the base = The number of lateral faces of the prism

or, s = f.

∴ We can say that the number of sides of the base of a prism and the number of lateral faces are equal.

Answer:

Step-by-step explanation:

Quadratic equations follow the formula ax^2+b+c and sometimes c or the third digit in the equation may not be there so C=0.

Exponential equations have exponents that are added to another exponent and supported by the base/coefficient.

Linear Equations have a specific formula which is Ax+By=C such a 2x+4y=8 and solve for both x and y.

There were no linear equations because none were solving for x and y, but most were quadratic equations and one exponential equation.
