A wedding tent is built in the shape of a right rectangular prism topped with a rectangular pyramid. The dimensions of the prism are 32 ft by 35 ft by 9 ft, and the height of the pyramid is 4 ft. Find the total volume of the tent. Round your answer to the nearest tenth if necessary. (Note: diagram is not drawn to scale.)

Answers

The total volume of the wedding tent is 14560 ft³.

To find the total volume of the wedding tent, we need to calculate the volume of both the rectangular prism and the rectangular pyramid, and then add them together.

The volume of a rectangular prism is given by the formula:

Volume_prism = length * width * height

In this case, the dimensions of the prism are 32 ft by 35 ft by 9 ft, so the volume of the prism is:

Volume_prism = 32 ft * 35 ft * 9 ft = 10080 ft³

The volume of a rectangular pyramid is given by the formula:

Volume_pyramid = (length * width * height) / 3

The dimensions of the top of the pyramid are the same as the base of the prism, so the length and width of the pyramid are both 32 ft. The height of the pyramid is 4 ft. Using these values, we can calculate the volume of the pyramid:

Volume_pyramid = (32 ft * 35 ft * 4 ft) / 3 = 4480 ft³

To find the total volume of the tent, we add the volume of the prism and the volume of the pyramid:

Total_volume = Volume_prism + Volume_pyramid

Total_volume = 10080 ft³ + 4480 ft³ = 14560 ft³

Angie decorates 8 cupcakes after putting 4 sugar flowers on each cupcake.

To find the number of cupcakes c Angie decorates, we can use the equation:4c = 32where 'c' is the number of cupcakes Angie decorates.

4 represents the number of sugar flowers Angie puts on each cupcake, and 32 is the total number of sugar flowers Angie puts on the cupcakes.

To solve this equation for c, we need to isolate c on one side of the equation. We can do this by dividing both sides of the equation by 4. This gives us:c = 8

Therefore, Angie decorates 8 cupcakes.Here's how we get to this answer:4c = 32Divide both sides by 4 to isolate c:c/4 = 32/4c = 8

El valor de un automóvil se deprecia exponencialmente a razón de 8% cada 3 años. Si el automóvil se compró nuevo en $240 000 en 1998, plantea una fórmula para el valor del automóvil (V ) en función del tiempo t y utilízala para calcular el valor que tendrá en 2010.


La ecuación que vas a utilizar es :
El valor inicial es b . El factor de cambio es a =
La ecuación queda como: .
El año 2010 corresponde al valor t :
Al sustituirlo en la ecuación, tenemos que V (t) :

Answers

La ecuación que nos da el valor del auto t años despues de 1998 es:

V(t) = $240,000*(0.92)^t

El valor de el auto en el año 2010 será de $88,239.93

¿Como encontrar la ecuacion exponencial?

La ecuación exponencial general es:

f(x) = A*(b)^x

Donde A es el valor inicial, b es el factor de cambio, y x es la variable.

En este caso, sabemos que el automovil se compra por $240,000 en 1998, entonces definimos 1998 como el tiempo inicial, t = 0, y el valor inicial será:

A = $240,000

El factor de cambio depende de que tanto decae o aumenta el valor del auto por año, en este caso decae un 8% por año, entonces tendremos:

b = 1 - 8%/100% = 1 - 0.08 = 0.92

El factor de cambio es 0.92

Entonces la ecuación que nos da el valor del auto t años despues de 1998 es:

V(t) = $240,000*(0.92)^t

Particularmente, 2010 es 12 años luego de 1998, entonces t = 12.

V(12) = $240,000*(0.92)^12 = $88,239.93

El valor de el auto en el año 2010 será de $88,239.93

Answers

Complete Question

What is the minimum sample size required to estimate a population mean with 90% confidence when the desired margin of error is 1.25? The standard deviation in a pre-selected sample is  7.5

Answer:

The minimum sample size is  \(n =97\)

Step-by-step explanation:

From the question  we are told that

 The margin of error is  \(E = 1.25\)

   The  standard deviation is  \(s = 7.5\)

Given that the confidence level is  90% then the level of significance is mathematically represented as

             \(\alpha = 100 - 90\)  

             \(\alpha =10\%\)  

             \(\alpha =0.10\)

Next we obtain the critical value of \(\frac{\alpha }{2}\) from the normal distribution table  

    The value is  \(Z_{\frac{ \alpha }{2} } = 1.645\)

   The  minimum sample size is mathematically evaluated as

         \(n = \frac{Z_{\frac{\alpha }{2} * s^2 }}{E^2 }\)

=>        \(n = \frac{1.645^2 * 7.5^2 }{1.25^2 }\)

=>        \(n =97\)

The method to find the increasing and decreasing interval is discussed below.

What is function?A function is a relation between a dependent and independent variable. Mathematically, we can write function as → y = f(x) = ax + b.

Given is to determine the increasing and decreasing interval.

Since the function is not given, we can discuss the ways in which the increasing or decreasing intervals can be found. It is given as follows -

Increasing and decreasing intervals of real numbers are the real-valued functions that tend to increase and decrease with the change in the value of the dependent variable of the function. To find intervals of increase and decrease, you need to determine the first derivative of the function. This is done to find the sign of the function, whether negative or positive. The function interval is said to be positive if the value of the function f (x) increases with an increase in the value of x. In contrast, the function interval is said to be negative if the value of the function f (x) decreases with the increase in the value of x.

Therefore, the method to find the increasing and decreasing interval is discussed above.

For the given probability density function,find the area under the function within one standard deviation of the mean. f(x)=1/4x[1,2]

Answers

The area under the probability density function within one standard deviation of the mean is approximately 0.6826.

What is probability?

Probability is the measure of the likelihood of an event occurring. It is a numerical value between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

The probability density function f(x) is defined as:

f(x) = 1/4x for 1 ≤ x ≤ 2

= 0 otherwise

To find the area under the function within one standard deviation of the mean, we first need to find the mean and standard deviation of the function.

The mean, or expected value, of a continuous probability density function is given by:

μ = ∫xf(x)dx

Substituting f(x) into the above formula, we get:

μ = ∫1² (1/4x) dx = (1/4)ln(2) ≈ 0.1733

Next, the variance of the probability density function is given by:

σ² = ∫(x-μ)²f(x)dx

Substituting f(x) and μ into the above formula, we get:

σ² = ∫1² [(x-0.1733)²/4x] dx ≈ 0.0396

The standard deviation is then given by:

σ = √(σ²) ≈ 0.1990

Within one standard deviation of the mean, the area under the probability density function is given by:

\($P(\mu-\sigma \leq x \leq \mu+\sigma) = \int_{\mu-\sigma}^{\mu+\sigma}f(x)dx$\)

Substituting μ and σ into the above formula, we get:

\($P(\mu-\sigma \leq x \leq \mu+\sigma) =\) \($\int_{0.1733-0.1990}^{0.1733+0.1990} \frac{1}{4x}\ dx$\)

P(μ-σ ≤ x ≤ μ+σ) ≈ 0.6826

Therefore, the area under the probability density function within one standard deviation of the mean is approximately 0.6826.

Sine

The sine of the angle is the ratio ...

  Sin = Opposite/Hypotenuse

We can go to the trouble to figure the hypotenuse, or we can choose the only suitable answer from the list provided. (It is the one marked already.)

The leg lengths of the triangle shown are 8 and 15, with leg 15 being opposite angle A. This is the first clue that the ratio will have 15 in the numerator. Only answer choice B matches.

Check

The value of the sine function is never greater than 1, eliminating answer choices A, C, and E, leaving choices B and D.

Since the side opposite angle A is the longest of the two legs, we know that angle A is more than 45°, and its sine is more than √2/2. That means choice D can be eliminated, since it is less than 1/2.

The sine of angle A is 15/17.

The value x= -2 makes the inequality  true.

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

12 > 2x + 4

Now, if we put x= 8 then

= 2x+ 8

= 2(8)+8

= 16+ 8

= 24 > 12

So, x=8 is not true

Now,  if we put x= 4 then

= 2x+ 8

= 2(4)+8

= 8+ 8

= 16 > 12

So, x=4 is not true

Now,  if we put x= 12 then

= 2x+ 8

= 2(12 )+8

= 24 + 8

= 32 > 12

So, x=12 is not true

and,  if we put x= -2 then

= 2x+ 8

= 2(-2)+8

= -4+ 8

= 4 < 12
