The solution of given equation [tex]x = \frac{3}{4}[/tex]

Step-by-step explanation:

Given equation  1+3 x  = -x +4

                 Add 'x' on both sides , we get

                     1 + 3 x + x = - x + x +4

                     1 + 4 x  = 4

       Subtract '1' on both sides , we get

                    1+4 x -1 = 4 -1

                         4 x = 3

      Dividing '4' on both sides, we get

                          [tex]\frac{4x}{4} = \frac{3}{4}[/tex]

                          [tex]x = \frac{3}{4}[/tex]

Answer:

C

Step-by-step explanation:

Since lines a, b, c, d, and XY are all parallel to each other, and are a part of the same triangle, they are all similar. Thus, we can compare rates -- the distance between P to Y is 12, and 2/3 of 12 is 8, so we need to find that length, which is C

The segment of line c shows the correct result of the dilation. Hence, the correct answer is option C.

Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.

Since lines a, b, c, d, and XY are all parallel and part of the same triangle, they are all similar. Thus, we can compare rates the distance between P to Y is 12, and 2/3 of 12 is 8, which is C.

Hence, the correct answer is option C.

There are 41 white marbles in the bag.

Let's assume the number of green marbles is represented by "x". According to the given information, the number of white marbles is 3 less than 4 times the number of green marbles.

Number of white marbles = 4x - 3

The total number of marbles is given as 52, so we can write the equation:

Number of white marbles + Number of green marbles = Total number of marbles

(4x - 3) + x = 52

Combining like terms:

5x - 3 = 52

Adding 3 to both sides:

5x = 55

Dividing both sides by 5:

x = 11

Therefore, the number of green marbles is 11.

To find the number of white marbles:

Number of white marbles = 4x - 3

                       = 4 * 11 - 3

                       = 44 - 3

                       = 41

Hence, there are 41 white marbles.

Answer:  7,500 passengers

Step-by-step explanation: Let's put the numbers from least to greatest...

5,000, 6,000, (7,000, 8,000,) 9,000, 10,000

Since there is an even number of numbers we will have two medians for the time being...

7,000 + 8,000 = 15,000

15,000 ÷ 2 = 7,500

Therefore, the median is 7,500, there are 7,500 passengers in total.

Answer:

(a) The mean and standard deviation of X is 2.6 and 1.2 respectively.

(b) The mean and standard deviation of T are 390 and 180 respectively.

(c) The distribution of T is N (390, 180²). The probability that all students’ requests can be accommodated is 0.7291.

Step-by-step explanation:

(a)

The random variable X is defined as the number of tickets requested by a randomly selected graduating student.

The probability distribution of the number of tickets wanted by the students for the graduation ceremony is as follows:

X      P (X)

0      0.05

1       0.15

2      0.25

3      0.25

4      0.30

The formula to compute the mean is:

[tex]\mu=\sum x\cdot P(X)[/tex]

Compute the mean number of tickets requested by a student as follows:

[tex]\mu=\sum x\cdot P(X)\\=(0\times 0.05)+(1\times 0.15)+(2\times 0.25)+(3\times 0.25)+(4\times 0.30)\\=2.6[/tex]

The formula of standard deviation of the number of tickets requested by a student as follows:

[tex]\sigma=\sqrt{E(X^{2})-\mu^{2}}[/tex]

Compute the standard deviation as follows:

[tex]\sigma=\sqrt{E(X^{2})-\mu^{2}}\\=\sqrt{[(0^{2}\times 0.05)+(1^{2}\times 0.15)+(2^{2}\times 0.25)+(3^{2}\times 0.25)+(4^{2}\times 0.30)]-(2.6)^{2}}\\=\sqrt{1.44}\\=1.2[/tex]

Thus, the mean and standard deviation of X is 2.6 and 1.2 respectively.

(b)

The random variable T is defined as the total number of tickets requested by the 150 students graduating this year.

That is, T = 150 X

Compute the mean of T as follows:

[tex]\mu=E(T)\\=E(150\cdot X)\\=150\times E(X)\\=150\times 2.6\\=390[/tex]

Compute the standard deviation of T as follows:

[tex]\sigma=SD(T)\\=SD(150\cdot X)\\=\sqrt{V(150\cdot X)}\\=\sqrt{150^{2}}\times SD(X)\\=150\times 1.2\\=180[/tex]

Thus, the mean and standard deviation of T are 390 and 180 respectively.

(c)

The maximum number of seats at the gym is, 500.

According to the Central Limit Theorem if we have a population with mean μ and standard deviation σ and we take appropriately huge random samples (n ≥ 30) from the population with replacement, then the distribution of the sum of values of X, i.e ∑X, will be approximately normally distributed.  

Here T = total number of seats requested.

Then, the mean of the distribution of the sum of values of X is given by,  

[tex]\mu_{T}=n\times \mu_{X}=390[/tex]  

And the standard deviation of the distribution of the sum of values of X is given by,  

[tex]\sigma_{T}=n\times \sigma_{X}=180[/tex]

So, the distribution of T is N (390, 180²).

Compute the probability that all students’ requests can be accommodated, i.e. less than 500 seats were requested as follows:

[tex]P(T<500)=P(\frac{T-\mu_{T}}{\sigma_{T}}<\frac{500-390}{180})\\=P(Z<0.61)\\=0.72907\\\approx 0.7291[/tex]

Thus, the probability that all students’ requests can be accommodated is 0.7291.

Answer: The area of the new parallelogram is multiplied by 18

Step-by-step explanation: Let the base and the height of the original parallelogram be ' x '

Base of the parallelogram = x

Height of the parallelogram = x

Area of parallelogram = l × b = lb

= x × x = x²

∴ Area of the original parallelogram = x²

∴ The base is multiplied by 3 = 3x

The height is multiplied by 6 = 6x

∴ Area of new parallelogram = 3x × 6x = 18x²

∴ The area of the new parallelogram is multiplied by = 18x²/ x²

Answer:

There is no error. This is a correct conclusion.

Step-by-step explanation:

If a sequence of rigid transformations

(translations, reflections, and rotations) and dilations can map △DCE onto △ABE, then the figures are similar.

Notice that both triangles are right triangles (at vertices B and C), with line AB and DC being the longer legs.

Therefore, if the triangles are similar, we should be able to map each pair of corresponding points onto each other with rigid transformations and dilations:

   D should be mapped onto A.

   C should be mapped onto B.

   E should be mapped onto itself.

Lennox used a reflection across line BE and a dilation about E to get △DCE as close as possible to △ABE. But still, point D did not map onto point A.

So we can conclude that it's not possible to map △DCE onto △ABE using a sequence of rigid transformations and dilations.

Lennox concluded:

"It's not possible to map △DCE onto △ABE using a sequence of rigid transformations and dilations, so the triangles are not similar."

There is no error. This is a correct conclusion.

Given the length(l), height(h) and width(w) of a rectangular prism.

Surface Area=2(lw+lh+wh)

For a rectangular prism with a height of h yards, a length of 2.6 yards, and a width of 3.5 yards.

Surface Area[tex]=2(2.6*3.5+2.6h+3.5h)[/tex]

[tex]=2(9.1+2.6h+3.5h)\\=18.2+5.2h+7h\\[/tex]

Surface Area= (18.2+12.2h) square yards

If the height, h=4 yards

Then the surface area of the rectangular prism

=18.2+12.2h

=18.2+12.2(4)

=18.2+48.8

=67 square yards

The statements that are true for this equation are:

- The equation is an exponential growth equation.

- $228.000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.

Step-by-step explanation:

We have the equation

[tex]V= 228,000(1.03)^t[/tex]

Where V: value of the real state and t: time in years.

As t is always positive in this case, and 1.03 is larger than 1, the value V will rise exponentially. The equation is an exponential growth equation.

The difference in value for each year is:

[tex]\dfrac{V_{t+1}}{V_t}=\dfrac{1.03^{t+1}}{1.03^t}=1.03^{t+1-t}=1.03\\\\\\V_{t+1}-V{t}=1.03V_t-V_t=0.03V_t[/tex]

We can conclude that the value increases each year 0.03 (3%) from the previous year value, starting from $228,000 in the year t=0.

$228.000 represents the initial cost of a real estate that appreciates 3% per year over the course of years.

[tex] y= 7(x+5)^2 -4[/tex]

The vertex form for a parabola is given by this expression:

[tex] y = a(x-h)^2 +k[/tex]

By direct comparison we see that for this case:

[tex] a = 7, h = -5 and k=-4[/tex]

And we know from the general expression that the vertex is:

[tex] V= (h,k)[/tex]

So then the vertex for this case is:

[tex] V= (-5,-4)[/tex]

Step-by-step explanation:

For this case we have the following function:

[tex] y= 7(x+5)^2 -4[/tex]

And we need to take in count that the vertex form for a parabola is given by this expression:

[tex] y = a(x-h)^2 +k[/tex]

By direct comparison we see that for this case:

[tex] a = 7, h = -5 and k=-4[/tex]

And we know from the general expression that the vertex is:

[tex] V= (h,k)[/tex]

So then the vertex for this case is:

[tex] V= (-5,-4)[/tex]
