Answer: The amount of alcohol the woman consumed can be calculated as follows:

Two glasses of wine * 22 grams of alcohol per glass = 44 grams of alcohol

To convert this amount to milliliters, we need to know the concentration of the alcohol, which is typically around 12% for wine. So, 44 grams of alcohol is equivalent to 44 grams / 0.12 g/mL = 367 mL.

Next, we can calculate the woman's blood alcohol content (BAC) using the following formula:

BAC = (Alcohol consumed in mL) / (Blood volume in mL) * 100%

The blood volume for a 103-pound woman with approximately 6 liters of blood can be estimated as follows:

6 liters * 1000 mL/liter = 6000 mL

So, the BAC can be calculated as follows:

BAC = (367 mL) / (6000 mL) * 100% = 0.0612 * 100% = 6.12%

Therefore, the woman's blood alcohol content would be 6.12% if all the alcohol were immediately absorbed into her bloodstream.

Answer: I do not have the capability to create a graph. However, I can tell you how to graph the parabola h(x) = -x^2 + 3.

A parabola is defined by its equation in the form y = ax^2 + bx + c, where a, b, and c are constants. In this case, a = -1, b = 0, and c = 3.

The vertex of the parabola is the highest or lowest point on the graph and is given by the coordinates (-b/2a, c - b^2/4a). For this parabola, the vertex is (0, 3), since b = 0 and a = -1.

To find another point on the parabola, you can plug in any x-value and use the equation of the parabola to find the corresponding y-value. For example, if you plug in x = -2, you get:

h(-2) = -(-2)^2 + 3

h(-2) = 4 + 3

h(-2) = 7

So the point (-2, 7) is also on the parabola.

With the vertex and one other point on the parabola, you can now graph the parabola.

Probability can be defined as the ratio of number of favourable outcomes and total number of outcomes.

The probability of matching four out of six numbers in a single ticket can be calculated as follows:

There are C(23, 6) = 8,145 possible combinations of six numbers from 1 through 23.

There are C(23, 4) = 1,531 possible combinations of four numbers from 1 through 23.

So, the probability of matching four out of six numbers in a single ticket is 1,531/8,145 = 19/102.

If you buy five tickets, the probability of matching four out of six numbers in at least one of them is 1 - (1 - 19/102)⁵ , which can be calculated as:

1 - (1 - 19/102)⁵ = 1 - 0.848⁵ = 1 - 0.640 = 0.360

Therefore, The answer is 0.360, or approximately 36/100.

Answer:

Step-by-step explanation:

A polynomial function has one or more real numbers as roots or zeros. These roots correspond to the values of x for which the function takes on the value of zero.

In this case, y = (x-2)(x+3)², we can factor the equation to find its zeros. The expression (x-2)(x+3)² can be factored into two terms: (x-2) and (x+3)².

The first term, (x-2), is equal to zero when x = 2, meaning that x = 2 is a root of the function.

The second term, (x+3)², is equal to zero when x = -3, meaning that x = -3 is another root of the function.

So, the function y = (x-2)(x+3)² has two roots, or zeros, at x = 2 and x = -3.

Answer: The momentum of the truck before the collision is given by the formula:

p_i = m_i * v_i, where m_i is the mass of the object and v_i is its velocity.

The momentum of the truck before the collision is:

p_i (truck) = 3000 kg * 10 m/s = 30000 kg m/s

The momentum of the car before the collision is:

p_i (car) = 1000 kg * 0 m/s = 0 kg m/s

The total initial momentum of the system is the sum of the initial momenta of the truck and car:

p_i (total) = p_i (truck) + p_i (car) = 30000 kg m/s + 0 kg m/s = 30000 kg m/s

After the collision, the final momentum of the system is the sum of the final momenta of the truck and car:

p_f (total) = p_f (truck) + p_f (car)

Let's call the velocity of the truck after the collision v_f (truck). The final momentum of the truck is:

p_f (truck) = 3000 kg * v_f (truck)

The final momentum of the car is:

p_f (car) = 1000 kg * 15 m/s = 15000 kg m/s

Using the conservation of momentum, we can write an equation:

p_f (total) = p_i (total)

30000 kg m/s = p_f (truck) + p_f (car)

30000 kg m/s = 3000 kg * v_f (truck) + 15000 kg m/s

30000 kg m/s = 3000 kg * v_f (truck) + 15000 kg m/s

v_f (truck) = (30000 kg m/s - 15000 kg m/s) / 3000 kg = 7.5 m/s

So, the velocity of the truck immediately after the collision is 7.5 m/s.

Slope line formula is used for determining the slope of a line. Based on the given points, the slope of line is 2/3.

To find the slope of the line passing through the given points, we can use the slope formula, which states that the slope of a line passing through two points (x1, y1) and (x2, y2) is given by the expression:

slope = (y2 - y1) / (x2 - x1)

Using this formula, we can calculate the slope of the line passing through the three given points as follows:

slope = (2 - (-2)) / (3 - (-3)) = 4/6 = 2/3

Therefore, the slope of the line passing through the given points is 2/3.

Alternatively, we can observe that the three points are collinear and lie on the same straight line. We can use this fact to find the slope of the line by computing the rise over run between any two of the points. For example, using the points (0,0) and (-3,-2), we have a rise of 2 and a run of 3, so the slope is 2/3. This confirms that the slope of the line passing through the given points is 2/3.

Answer:

Step-by-step explanation:

Yes, the ratios 4:6 and 2:3 are equivalent.

To see why, we can compare the proportions of the two ratios by dividing each term by the smaller term in each ratio.

In the ratio 4:6, if we divide both terms by 4, we get:

4/4 : 6/4 = 1 : 3/2

In the ratio 2:3, if we divide both terms by 2, we get:

2/2 : 3/2 = 1 : 3/2

Since both ratios reduce to the same proportion of 1 : 3/2, we can conclude that the ratios 4:6 and 2:3 are equivalent.

Ratios are mathematical expressions that compare two or more quantities. When two ratios are equivalent, it means that they represent the same proportion, even if the numbers in the ratios are different.

To compare the ratios 4:6 and 2:3, we divided each term in each ratio by the smallest term. This is because dividing each term by the same number will keep the proportion of the ratio the same.

For example, in the ratio 4:6, dividing both terms by 4 gave us the proportion of 1 : 3/2, which is the same as the proportion of 2:3 when divided by 2. This means that, even though the numbers in the two ratios are different, they represent the same proportion, and therefore the ratios are equivalent.

It's important to note that when comparing ratios, it's best to reduce the ratios to their simplest form so that the proportions are more easily compared.

The median of 20 is the most accurate to use, since the data is skewed.

The most accurate measure of center to use in this case is the median of 20. This is because the data is skewed, with a few high-value donations (such as the two donations of 55 dollars) that pull the mean up. However, most of the donations are clustered around 10 to 20 dollars. As a result, the median, which is the middle value when the data is sorted in order, is a better representation of the "typical" donation amount.

In this case, the median is 20, which means that half of the donations were less than 20 dollars and half were more. This is a more accurate representation of the central tendency of the data than the mean of 22.7, which is influenced by the high-value donations. Therefore, the charity should use the median of 20 to accurately represent the typical donations received.

The longest border of the Mann's park is 228.6 meter.

The Triangle Inequality It is a basic principle of geometry that the lengths of any two sides of a triangle must add up to more than the length of the third side. In other words, the longest side of any triangle must be shorter than the total length of the other two sides.

In this case, the shortest side of Mann Park measures 5 inches, and the two longer sides measure 7 inches and 9 inches.

So, the sum of the lengths of the two longer sides is:

' 7 inches + 9 inches = 16 inches.

Since 5 inches is less than 16 inches, we know that the 5-inch side is the shortest side, and the 9-inch side is the longest side.

One inch is approximately equal to 0.0254 meters, so we have:

= 9 inches x 0.0254 meters/inch

= 0.2286 meters

Since the shortest side is 1000 meters long, the longest side is:

= 1000 meters x 0.2286 meters/inch

= 228.6 meters long.

Therefore, the longest border of Mann Park is approximately 228.6 meters long.

Step-by-step explanation:

To evaluate the expression Z₂ * Z3 / Z₁, we first need to find the complex numbers Z₂ * Z3 and Z₁.

Z₂ * Z3 = -2 + 3i * 4 + 2i = (-8 + 14i) + (-6 + 6i) = -8 + 8i

Z₁ = 3 - 2i

So, Z₂ * Z3 / Z₁ = (-8 + 8i) / (3 - 2i)

We can simplify this expression by multiplying the numerator and denominator by the complex conjugate of the denominator, which is (3 + 2i).

Z₂ * Z3 / Z₁ = (-8 + 8i) / (3 - 2i) * (3 + 2i) / (3 + 2i) = (-8 + 8i) * (3 + 2i) / (3 - 2i) * (3 + 2i)

Z₂ * Z3 / Z₁ = ((-8 * 3 + 8 * 2i) + (8 * 3 + 8 * 2i)) / (3^2 + (-2i)^2) = (16 + 16i) / 13
