To calculate the probability of getting two numbers whose product is even when throwing two 4-sided dice simultaneously, we can use the complement rule, which states that the probability of an event happening is equal to 1 minus the probability of the event not happening.

To start, we can determine the probability of getting two numbers whose product is odd. This can only happen if both dice show odd numbers, which occurs with a probability of 1/2 * 1/2 = 1/4. Therefore, the probability of getting two numbers whose product is even is:

Probability of even product = 1 - Probability of odd product

Probability of even product = 1 - 1/4

Probability of even product = 3/4

So, the probability of getting two numbers whose product is even when throwing two 4-sided dice simultaneously is 3/4 or 0.75. This means that in 75% of the cases when two 4-sided dice are thrown, the product of the two numbers will be even.

Triangle AXC is congruent to triangle AYB by the SAS Congruence Criteria.

In geometry, two triangles are said to be congruent if they have the same shape and size. More specifically, two triangles are congruent if all three sides and all three angles of one triangle are equal to the corresponding sides and angles of the other triangle. When two triangles are congruent, they can be superimposed on top of each other, and all corresponding parts of the triangles will match exactly.

There are several ways to prove that two triangles are congruent, including using the side-angle-side (SAS) theorem, the angle-side-angle (ASA) theorem, the side-side-side (SSS) theorem, and the hypotenuse-leg (HL) theorem.

Given that |AB|=|CD| and triangle ABC is isosceles.

We need to prove that triangle AXC = triangle AYB.

To do so, we will use the Side-Angle-Side (SAS) Congruence Criteria.

AC = BC (Given)

∠ACX = ∠BCY (Vertical Angles)

∠CAX = ∠CBY (Base Angles of Isosceles Triangle)

Therefore, triangle AXC is congruent to triangle AYB by the SAS Congruence Criteria.

Hence, proved.

A person bought two old scooters for Rs. 9000. By selling one at a profit of 25% and the other at a loss of 20%, to neither gain nor lose. The cost of each scooter is Rs. 4000 and Rs. 5,000.

Let the cost price of the first scooter be Rs. x and the cost price of the second scooter = Rs. (9000 - x)

Given, the first scooter was sold at a profit of 25%.

Selling price of first scooter = x + 0.25x = 1.25x

Given, the second scooter was sold at a loss of 20%.

Selling price of second scooter = 0.8(9000 - x)

Now, according to the question, there is no profit and no loss.

Therefore, Total Selling Price = Cost Price=> (1.25x) + 0.8(9000 - x) = 9000=> 1.25x + 7200 - 0.8x = 9000=> 0.45x = 1800=> x = Rs. 4000

So, the cost price of the first scooter is Rs. 4000.

The cost price of the second scooter is Rs. (9000 - 4000) = Rs. 5000

Therefore, the cost of each scooter is Rs. 4000 and Rs. 5,000.

Answer:

y = 1/2x - 3/2

General Formulas and Concepts:

Order of Operations: BPEMDAS

Slope Formula: \(m=\frac{y_2-y_1}{x_2-x_1}\)

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define coordinates:

(-3, -3)

(1, -1)

Step 2: Find slope m

\(m=\frac{-1-(-3)}{1-(-3)}\)

\(m=\frac{-1+3}{1+3}\)

\(m=\frac{2}{4}\)

\(m=\frac{1}{2}\)

Step 3: Find y-intercept b

Step 4: Write linear equation:

Plug in the newly found b into the equation.

y = 1/2x - 3/2

rise/run = slope

slope = 2/4 = 1/2

y = 1/2x +b

now, choose a point on the line and substitute y for the y coordinate and x for the x coordinate -----------> i will use (1, -1)

-1 = 1/2(1) + b

-1 = 1/2 +b

subtract 1/2 from both sides

-3/2 = b

y = 1/2x - 3/2

Answer:

1. Y+2/5y

2. y-0.32y

3. Y-2/5y

4. y+0.32y

Step-by-step explanation:

Answer:

y = -x + 30

Step-by-step explanation:

You will want to put the equation in the form y = mx + b where m is the slope and b is the y-intercept (an example is y = 2x - 1).

First, to find the slope you want to find how much x goes up by when y goes up by 1. You know from the table that when y goes up by 5, x goes up by -5 (using the points (10, 20) and (5, 25))

Then, you can divide each value by 5, so it would be when y goes up by 1, x goes up by -1. That means the slope is -1.

So far, the equation is y = -x + b. To find b, you can plug in one of the points you have and solve for b. For example, substitute in x = 10 and y = 20, so:

20 = -10 + b

add 10 to both sides

30 = b

So you know the equation is y = -x + 30

Please let me know if any parts of these explanation are confusing, I definitely think this concept can be confusing at time. Good luck with your work! :)

Answer:

To create an equation, you need to find the slope first. The slope formula is \(\frac{y^2-y^1}{x^2-x^1}\). Let's use two random coordinates: (10,20) and (5,25). Plug in these digits into the formula to get \(\frac{25-20}{5-10}\). Simplify to get \(\frac{5}{-5}\) or -1. The equation would look like y=-x+b. Now we need to find b. Again, let's use a random coordinate: (10,20). Plug in the digits into the variables to get 20=-10+b. Add 10 on both sides to get 30=b. So, the equation would be y=-x+30.

Step-by-step explanation:

Because it is an isosceles triangle, the two base angles are the same (55° and 55°)

All triangles angles must add up to 180°, so 180-55-55 will give us the missing angle (x).

The maximum probability that a photon with the polarization state will be transmitted through the A filter is 1/2

To solve this problem, we need to use Malus' law, which states that the intensity of light transmitted through a polarizer is proportional to the square of the cosine of the angle between the polarization direction of the incoming light and the axis of the polarizer.

To find the overall probability that a photon will be transmitted through all three filters, we need to multiply the probabilities of each filter

P = 1/2 × cos²(θ) × 1

We are not given the angle θ, so we cannot calculate the exact value of P. However, we can calculate the maximum value of P, which occurs when the rotated filter is aligned with the A filter (i.e., θ = 0). In this case, P = 1/2.

The values of the z-statistic that are statistically significant at the alpha=0.005 level are greater than 2.576.

To determine the values of the z-statistic that are statistically significant at the alpha=0.005 level for testing the hypothesis H₀: μ = 0 against Hₐ: μ > 0, we need to find the critical value from the standard normal distribution.

The critical value corresponds to the z-score that marks the boundary of the rejection region. In this case, since the alternative hypothesis is one-sided (μ > 0), we are interested in the right-tail of the distribution.

The alpha level of 0.005 indicates that we want to reject the null hypothesis at a significance level of 0.005, which corresponds to a 0.5% area in the right tail of the standard normal distribution.

Using a standard normal distribution table or a calculator, we can find the z-score that corresponds to an area of 0.005 in the right tail. The z-score that corresponds to an area of 0.005 is approximately 2.576.

Thus, the values of the z-statistic that are statistically significant at the alpha=0.005 level are greater than 2.576.

If the calculated z-statistic for the sample falls in the rejection region (greater than 2.576), we can reject the null hypothesis H₀: μ = 0 in favor of the alternative hypothesis Hₐ: μ > 0 at the alpha=0.005 level of significance.

\(Area = 339.29\ in^2\)

Step-by-step explanation:

Given

See attachment

Required

Determine the total surface area

From the attachment:

\(r = 3\ in\) --- radius

\(h = 15\ in\) --- height

The total surface area:

\(Area = 2\pi r(r + h)\)

Substitute values for r and h

\(Area = 2\pi * 3(3 + 15)\)

\(Area = 2\pi * 3(18)\)

Remove bracket

\(Area = 2\pi * 3 * 18\)

\(Area = 2\pi * 54\)

\(\pi = \frac{22}{7}\)

So, we have:

\(Area = 2 * \frac{22}{7} * 54\)

\(Area = \frac{2 * 22 * 54}{7}\)

\(Area = \frac{2376}{7}\)

\(Area = 339.42\)

Hence, the closest is:

\(Area = 339.29\ in^2\)

The probability that the committee has a majority of women is approximately 0.0044.

To calculate the probability that the committee has a majority of women, we need to determine the number of ways we can select a committee with a majority of women and divide it by the total number of possible committees.

First, let's calculate the total number of possible committees. Since there are 63 senators in total (19 women + 44 men), we have 63 options for the first committee member, 62 options for the second, and so on.

Therefore, there are 63*62*61*60*59 = 65,719,040 possible committees.

Next, let's calculate the number of ways we can select a committee with a majority of women. Since there are 19 women in the NY Senate, we have 19 options for the first committee member, 18 options for the second, and so on.

Therefore, there are 19*18*17*16*15 = 28,7280 ways to select a committee with a majority of women.

Finally, let's calculate the probability by dividing the number of committees with a majority of women by the total number of possible committees:

287280/65719040 ≈ 0.0044.

In conclusion, the probability that the committee has a majority of women is approximately 0.0044.
