If,(2√3)p=78,then find p?​

Answer:

7,7, and 7

Step-by-step explanation:

If she vase is cubical we know that all 3 dimensions are the same. This means that x^3 = 343. So we know the answer is the cube root of 343, which is 7

The dimensions of the cubic vase are 7 by 7 by 7.

A three-dimensional object with six congruent square faces is called a cube. The cube's six square faces all have the same dimensions.

Given that the volume of the cubic vessel is 343 cubic inches.

The formula for the volume of a cube of side length a is:

V =a³

Substitute V= 343:

343 = a³

Or, a = ∛343

a = 7

Hence, the dimensions of the cubic vase are 7 by 7 by 7.

The correct hypotheses to be tested based on the given information are H₀: Pm - Pf = 0 vs. Hₐ: Pm - Pf < 0 (option c).

These hypotheses reflect the conjecture that men are more likely to work than women. In hypothesis testing, the null hypothesis (H₀) typically represents the assumption of no difference or no effect, while the alternative hypothesis (Hₐ) represents the claim or hypothesis we want to support.

In this case, the null hypothesis states that there is no difference between the proportions of male and female college students who worked last summer (Pm - Pf = 0). The alternative hypothesis states that the proportion of male college students who worked last summer is greater than the proportion of female college students who worked (Pm - Pf < 0).

By testing these hypotheses using appropriate statistical methods, we can determine if the observed data supports the claim that men are more likely to work than women or if there is no significant difference between the two proportions. The correct option is c.

The monthly depreciation is \(V(t) = 15200(0.9865)^t\), and the value after 7 years is (d) $4900

The yearly depreciation is given as:

\(V(t) = 15200(0.85)^t\)

There are 12 months in a year, so the monthly depreciation would be

\(V(t) = 15200(0.85)^{\frac{t}{12}}\)

Where t represents the number of months

Rewrite the expression as:

\(V(t) = 15200(0.85^\frac{1}{12})^t\)

Evaluate the exponent of 1/12

\(V(t) = 15200(0.9865)^t\)

After 7 years, we have:

\(t =7 \times 12\)

\(t =84\)

So, the value of the motorcycle after 7 years is

\(V(84) = 15200(0.9865)^{84}\)

\(V(84) = 4852.88\)

Approximate to the nearest hundred dollar

Answer:

\( \frac{x}{4} + \frac{1}{2} = \frac{1}{8} \)

\( \frac{x}{4} = - \frac{3}{8} \)

\(x = - \frac{3}{2} = - 1 \frac{1}{2} \)

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

Consider the equation, we have only one x term, so taking all the terms without x to the other side and terms with x on one side.

x/4 + 1/2 = 1/8

Take the 1/2 term on the other side,

x/4=1/8 - 1/2

Taking the LCM on the Right side,

x/4 = (1-4) / 8

x/4 = -3/8

Now, we have x/4 so what we can do is, shift the 4 to the other side too, we get,

x = ( -3/8) * 4

x = -3/2

The solution to the equation x/4 + 1/2 = 1/8 is x = -3/2.

Multiplying these values, we get 20x3=60. Therefore, it will take 60 unit cubes to completely fill the rectangular prism.

To find the number of unit cubes required to completely fill the rectangular prism, we need to know the total number of unit cubes that can fit inside the prism. We can determine this by counting the number of unit cubes that can fit in one layer of the prism, and then multiplying it by the number of layers in the prism.

Let's assume that the dimensions of the rectangular prism are length (L), width (W) and height (H), and that it is partially filled with unit cubes. We can count the number of unit cubes in one layer of the prism by multiplying L by W. This gives us the area of the base of the prism, which is the number of unit cubes that can fit in one layer.

Next, we need to count the number of layers in the prism. This is simply the height (H) of the prism. Once we have both these values, we can multiply them to find the total number of unit cubes required to fill the prism.

For example, if the dimensions of the rectangular prism are L=4, W=5 and H=3, and it is partially filled with unit cubes, we can count the number of unit cubes in one layer as 4x5=20. The number of layers in the prism is 3. Multiplying these values, we get 20x3=60. Therefore, it will take 60 unit cubes to completely fill the rectangular prism.

We cannot say that the two events are independent since the probability of eating pizza and sushi together is not known. If the probability of eating both together is 0, then the events are mutually exclusive, and if the probability is greater than 0, then the events are dependent.

We cannot say that the events of Marco eating sushi and pizza are independent. Two events are independent if the occurrence of one does not affect the probability of the other. However, in this case, if Marco eats sushi for dinner, it reduces the probability that he will eat pizza for dinner since he never eats both together.

The first step is to find the mean number of incorrect answers. Since there are 11 questions, and each question has a 50/50 chance of being answered incorrectly, we can expect the student to get 5.5 questions wrong on average.

Next, we need to calculate the variance. To do this, we can use the formula:

Variance = p(1-p)n

Where p is the probability of getting a question wrong (0.5), and n is the number of questions (11).

Variance = 0.5(1-0.5)11 = 1.375

Finally, we can find the standard deviation by taking the square root of the variance:

Standard deviation = sqrt(1.375) = 1.17 (rounded to two decimal places)

Therefore, the standard deviation of the number of incorrect answers on the exam is 1.17.

Answer:

Area = \(561.2485\) square centimeter

If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.

Step-by-step explanation:

As we know the circumference of a circle is \(2\pi r\)

The radius of the hub cap needs to be devised to determine the area

\(83.96\) \(= 2* 3.14*r\)

\(r = \frac{83.96}{2*3.14}\)

\(r = 13.37\) centimeters

Area of the hub cap = \(\pi r^{2}\)

Substituting the devised value of r in the above equation, we get -

\(3.14 * 13.37^2\\\)

\(561.2485\) square centimeter

If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.

Since we have a direct variation, we can use the following equation:

where k is the constant of variation.

If we use the point (6,18), then, we have:

now that we have that the constant of variation is k = 3, we can use this information to find n:

therefore, n = -1

The radius of the circle is approximately 12.183ft.

When finding the radius of a circle in which the central angle, intercepts an arc of the given length, we use the formula:

s=rα where s is the length of the arc, r is the radius of the circle and α is the angle in radians, so we need to convert the given central angle to radians.

Here is a step-by-step solution:

Given that α = 126° and s = 4ft,

we first need to convert α to radians by using the formula:

π radians = 180°or1 radian = 180°/πα = 126°= 126π/180 radians= 7π/10 radians Using the formula s = rα,

we can solve for the radius:r = s/α= 4/ (7π/10)= (40/7)π≈ 12.183ft

Answer:

2.0 x \(10^{1}\)

Step-by-step explanation:

1. length = 3.2 x \(10^{5}\) m

width = 1.6 x \(10^{4}\) m

Area of a rectangle = length x width

                                = (3.2 x \(10^{5}\)) x (1.6 x \(10^{4}\))

                                = 5.12 x \(10^{9}\) \(m^{2}\)

2. length = 1.28 x \(10^{7}\) m

   width = 8 x \(10^{3}\) m

Area of a rectangle = length x width

                                 = (1.28 x \(10^{7}\)) x (8 x \(10^{3}\))

                                 = 1.024 x \(10^{11}\) \(m^{2}\)

\(\frac{Area of rectangle 2}{Area of rectangle 1}\) = \(\frac{1.024*10^{11} }{5.12*10^{9} }\)

                       = 20

                       = 2.0 x \(10^{1}\)

Thus,

The area of rectangle 2 is 2.0 x \(10^{1}\) times greater than the area of rectangle 1.

Answer:  (x, y) = (-12, 3)

This means x = -12 and y = 3 pair up together to form the solution.

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

Work Shown

1/2 = 0.5

0.5x + 6y = 12

0.5x + 6(x+15) = 12 .... plug in y = x+15

0.5x+6x+90 = 12

6.5x + 90 = 12

6.5x = 12-90

6.5x = -78

x = -78/(6.5)

x = -12

Then,

y = x+15

y = -12+15

y = 3

The solution as an ordered pair is (x, y) = (-12, 3)

That is the shorthand way to indicate x = -12 and y = 3 pair up together to form the full solution.

-----------------

Check:

Plug x = -12 and y = 3 into the first equation. Simplify both sides.

0.5x + 6y = 12

0.5*(-12) + 6*3 = 12

-6 + 18 = 12

12 = 12

We reached a true statement, which confirms the first equation is true when x = -12 and y = 3.

Repeat for the second equation.

y = x+15

-3 = -12+15

-3 = -3

This equation is true as well. Both equations are confirmed.

A visual way to confirm the answer is to graph the original equations on the same xy grid. The two lines intersect at (-12, 3). See the diagram below. I used GeoGebra to make the graph. Desmos is another option.
