Carlos can expect the value of the computer to be $580 in 3 years after purchase.

To find the exponential equation in the form y=a(b)ˣ that models the value of the computer, we need to determine the initial value and the rate of decay.

The initial value of the computer is $1,350, and its value after one year is $810.

We can use this information to find the rate of decay as follows:

810 = 1350 × b¹

b = 0.6

So the exponential equation is:

y = 1350(0.6)ˣ

To find the value of the computer 3 years after purchase, we can substitute x = 3 into the equation:

y = 1350(0.6)³= 583.2

Hence, Carlos can expect the value of the computer to be $580 in 3 years after purchase.

The p-value of the test statistic is 0.0000 (rounded off to four decimal places).

The p-value of the test statistic can be calculated by subtracting the area under the normal curve from the test statistic to infinity in the direction of the alternative hypothesis.

We are given that a political study has been carried out, taking a sample of 800 voters in the town. The sample shows that 59% of the residents favored construction. A political strategist wants to test the claim that the percentage of residents who favor construction is over 54%.

The hypothesis can be defined as follows:

Null hypothesis (H0): p ≤ 0.54, where p is the proportion of residents who favor the construction of the bridge.

Alternative hypothesis (Ha): p > 0.54, where p is the proportion of residents who favor the construction of the bridge.

To calculate the test statistic, we use the formula given below:

z = (p - P) / √[P(1-P) / n]

Here, P = 0.54, n = 800, p = 0.59

Putting these values in the above formula, we get:

z = (0.59 - 0.54) / √[0.54(1-0.54) / 800] = 5.06

To determine the p-value of the test statistic, we need to calculate the area under the normal curve from 5.06 to infinity in the direction of the alternative hypothesis. As the alternative hypothesis is one-tailed, we use the standard normal distribution table to find the corresponding area under the curve. The area can be calculated as:

P(Z > 5.06) = 0.00000035 (using the standard normal distribution table)

Therefore, the p-value of the test statistic is 0.0000 (rounded to four decimal places).

The sides of the piece of cardboard have to be 10 cm long in order for the volume of the box to equal 48 cm³

Let us assume that the dimension of the square piece of cardboard = m × m

If we cut a 3 cm square out of each corner, then each side of the square base will be (m - 6) cm.  

The height of the box, when folded, will be 3 cm.  

The volume of the box is:

V= (height) × (width) × (length)

V = 3 (m - 6) (m - 6)

V = 48 cm³

m² - 12m + 36 = 16

m² - 12m + 36 - 16 = 0

m² - 12m + 20 = 0

m² - 10m - 2m + 20 = 0

The probability that at least one of Blanca's cards has a number greater than at least one of Amira's cards is 0.705 or approximately 70.5%.

The total number of ways in which Blanca can choose two cards out of 23 is given by the combination formula C(23, 2), which is equal to 253.

The value of k can range from 3 (if Amira's cards are 1 and 2) to 25 (if Amira's cards are 24 and 25). Therefore, the total number of ways in which Blanca can pick two cards that are both greater than Amira's cards is:

C(23, 2) - C(2, 2) - C(3, 2) - ... - C(23, 2) = 23C(23, 1) - (C(2, 2) + C(3, 2) + ... + C(23, 2)) = 253 - 276 = -23

Since the result is negative, it means that there are no ways in which Blanca can pick two cards that are both greater than Amira's cards. Therefore, the probability of this case is 0.

P(Case 2) = (number of ways in which Blanca can pick one card greater than Amira's and one card less than Amira's) / (total number of ways in which Blanca can pick two cards out of 23) = 44,550 / C(23, 2) = 0.705

Finally, the probability of at least one of Blanca's cards having a number greater than at least one of Amira's cards is given by the sum of the probabilities of Case 1 and Case 2:

P(at least one of Blanca's cards is greater) = P(Case 1) + P(Case 2) = 0 + 0.705 = 0.705 or 70.5%

In conclusion there is only one solution to the system of equations and that is for x and y that satisfies both equations: x = 19 and y = -83.

How to solve and what does an equation mean?

We have two equations:

x + 5 = 24

5x = 12 - y

For the first equation, we can isolate x by subtracting 5 from both sides:

x = 19

Now we can substitute x = 19 into the second equation:

5(19) = 12 - y

95 = 12 - y

y = -83

So we have found a unique solution for x and y that satisfies both equations: x = 19 and y = -83.

Therefore, there is only one solution to the system of equations.

The height of the triangle is approximately 7.31 units.

What is  Pythagorean theorem ?

The Pythagorean theorem is a fundamental theorem in geometry that relates to the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In mathematical notation, the Pythagorean theorem can be written as:

a^2 + b^2 = c^2

where a and b are the lengths of the legs (the sides adjacent to the right angle) and c is the length of the hypotenuse.

According to the question:

Since triangle ABC is a right triangle with angle B = 90 degrees, we can use the Pythagorean theorem to find the length of side BC:

[tex]BC^2 = AC^2 - AB^2[/tex]

[tex]BC^2 = 30^2 - h^2[/tex]

[tex]BC = \sqrt{30^2 - h^2}[/tex]

Now, let's consider triangle ABD. We know that AD = 25 and DC = 11, so BD = BC - DC:

BD = BC - DC

[tex]BD = \sqrt{30^2 - h^2} - 11[/tex]

Since the line passing through vertex A is perpendicular to BC, we know that triangles ABD and ABC are similar. Therefore, we can use the ratio of corresponding sides to find the value of h:

h/AB = AB/AC

h/AB = AB/30

[tex]AB^2 = h*30[/tex]

[tex]AB =\ sqrt{h*30}[/tex]

Now, using the fact that AD + DC = BC, we can write:

AD + DC = BD + AB

[tex]25 + 11 = \sqrt{30^2 - h^2} - 11 +\sqrt{h*30}[/tex]

[tex]36 = \sqrt{30^2 - h^2} + \sqrt{h*30}[/tex]

Squaring both sides, we get:

[tex]1296 = 30^2 - h^2 + 2\sqrt{h*30}\sqrt{30^2 - h^2} + h*30[/tex]

[tex]1296 = 900 - h^2 + 2\sqrt{30h - h^3} + 30*h[/tex]

[tex]396 = 32\sqrt{30*h - h^3}[/tex]

Squaring again, we get:

[tex]156816 = 960h^2 - 96h^4[/tex]

[tex]h^4 - 10h^2 + 1639/12 = 0[/tex]

Using the quadratic formula, we get:

[tex]h^2 = (10 \± \sqrt{10^2 - 4(1)(1639/12))}/2[/tex]

[tex]h^2 = (10 \± \sqrt{1561})/2[/tex]

Since h must be positive, we take the positive square root:

[tex]h = \sqrt{(10 + sqrt(1561)}/2) \approx 7.31[/tex]

Therefore, the height of the triangle is approximately 7.31 units.

The measure of angles JKL, KJM and KRL are -51°, 105° and 51° respectively and the length of diagonal JL is 81 units.

An isosceles trapezoid is a four-sided polygon with two opposite sides parallel and two other sides of equal length.

In Quadrilateral JKLM,

KR = 42 and JR = 39,

R being the midpoint of diagonal.

Also, angle KMJ = 27° and KML = 78°.

The measure of angle JKL is equal to the difference of given angles KMJ and KML.

Therefore,

Angle JKL = KML-KMJ

       = 78°- 27°

       = 51°

The measure of angle KJM is equal to the sum of given angles KMJ and KML.

Therefore,

Angle KJM = KMJ + KML

       = 27° + 78°

       = 105°

The measure of angle KRL is equal to the difference of given angles KML and KMJ.

Therefore,

Angle KRL = KML - KMJ

       = 78° - 27°

       = 51°

The length of Diagonal JL is equal to the sum of lengths of given sides KR and JR.

Therefore,

Length of JL = KR + JR

Based on the information provided, the relationship between velocity and time taken is V = 4 + 0.5t.

We can start by using the formula for velocity with constant acceleration:

V = Vo + at

where V is the final velocity, Vo is the initial velocity, a is the constant acceleration, and t is the time taken.

We know that the velocity is partly constant and partly varies with time, so we can write:

V = Vc + Vv

where Vc is the constant part of the velocity and Vv is the part that varies with time.

Using the given information, we can set up a system of equations:

9 = Vc + Vv (when t = 8s)

11 = Vc + Vv (when t = 12s)

Subtracting the first equation from the second, we get:

11 - 9 = (Vc + Vv) - (Vc + Vv)

2 = Vv (when t = 12s) - Vv (when t = 8s)

2 = Vv (12) - Vv (8)

2 = 4Vv

Vv = 0.5 m/s

Now we can use either of the two original equations to find Vc:

9 = Vc + 0.5(8)

Vc = 4 m/s

Given sin∠X = cos∠Y and m∠X = 72°, we can find the measure of angle Y to be 18° since angles X and Y are complementary.

The problem states that sin∠X = cos∠Y and m∠X = 72°, and we are asked to find the measure of angle Y.

The first thing to notice is that sin∠X = cos∠Y means that the sine of angle X is equal to the cosine of angle Y. By the definition of sine and cosine, we know that:

sin∠X = opposite/hypotenuse

cos∠Y = adjacent/hypotenuse

where "opposite" and "adjacent" are the lengths of the sides of a right triangle that correspond to angles X and Y, respectively, and "hypotenuse" is the length of the hypotenuse of the triangle.

Since sin∠X = cos∠Y, we can set the two expressions equal to each other:

sin∠X = cos∠Y

opposite/hypotenuse = adjacent/hypotenuse

opposite = adjacent

This tells us that the lengths of the opposite and adjacent sides of the right triangle are equal. Since these sides are opposite and adjacent to angles X and Y, respectively, this means that angles X and Y are complementary angles (i.e., the sum of their measures is 90°).

We know that angle X has a measure of 72°, so we can use the fact that angles X and Y are complementary to find the measure of angle Y:

m∠Y = 90° - m∠X

m∠Y = 90° - 72°

m∠Y = 18°
