Mindy's pay depends on the number of boots she produced. According to the given pay scale, we can break down her pay as follows:

For the first 50 boots, Mindy earns $1.65 per boot. So, for the first 50 boots, her pay is 50 * $1.65 = $82.50.

For the next 100 boots (51-150), Mindy earns $3.30 per boot. So, for these 100 boots, her pay is 100 * $3.30 = $330.

For the next 50 boots (151-200), Mindy earns $4.95 per boot. So, for these 50 boots, her pay is 50 * $4.95 = $247.50.

In total, Mindy has produced 200 boots so far, and her pay for these boots is $82.50 + $330 + $247.50 = $660.

Now, for the remaining 192 - 200 = -8 boots (less than 200), Mindy earns $6.00 per boot. Since she hasn't produced any additional boots beyond 200, we don't need to consider this part.

Therefore, Mindy's pay for producing 192 boots is $660 (according to the breakdown above).

So, the correct answer is E. None of these.

The probability of choosing 3 men and 1 woman at random for a 4 person committee can be calculated using the combination formula.

We want to choose 3 men from a pool of 10 men, which can be done in 10 choose 3 ways. We also want to choose 1 woman from a pool of 6 women, which can be done in 6 choose 1 ways. The total number of ways to choose a 4 person committee from a pool of 16 people is 16 choose 4. Therefore, the probability of choosing 3 men and 1 woman at random for a 4 person committee is:

(10 choose 3) * (6 choose 1) / (16 choose 4) = 120 * 6 / 1820 = 0.3956

So, the probability of choosing 3 men and 1 woman at random for a 4 person committee is approximately 0.3956 or 39.56%. This means that if we randomly choose a 4 person committee from a pool of 10 men and 6 women, there is a 39.56% chance that the committee will consist of 3 men and 1 woman.

Finally, we need to subtract one-half the original number, which is $\frac{x}{2}$. So the final expression is:$$\frac{x+100}{2} - \frac{x}{2} = 50$$

1. Let's call the original number x.
2. Double the number: 2x
3. Add 200: 2x + 200
4. Divide the answer by 4: (2x + 200) / 4
5. Subtract one-half the original number: ((2x + 200) / 4) - (x / 2)

Now let's simplify the expression:

((2x + 200) / 4) - (x / 2)

= (2x/4 + 200/4) - (x / 2)

If a flag pole that is 15 feet tall casts a shadow that is 22 feet long. at the same time of day, the shadow of a nearby tree is 52.3 feet long then the tree is 35.5 feet tall

To determine the height of the tree, we need to use ratios and proportions. We know that the flagpole is 15 feet tall and casts a shadow of 22 feet. Using these values, we can create a proportion:
15/22 = x/52.3
To solve for x, we can cross-multiply:
15 x 52.3 = 22 x
x = (15 x 52.3)/22
x = 35.5
Therefore, the tree is 35.5 feet tall.
In mathematics, proportions are often used to compare two quantities. In this case, we used the ratio of the height of the flagpole to the length of its shadow to create a proportion and find the height of the nearby tree. It's important to note that this calculation assumes that both the flagpole and tree are standing vertically and that the angle of the sun's rays is constant. Understanding and using proportions is a valuable skill in many areas of math and science, including geometry, physics, and engineering. By using ratios and proportions, we can compare different quantities and make calculations that help us better understand the world around us.

the probability of drawing 3 or more white marbles when 5 marbles are drawn from the bag without replacement.

To calculate this probability, we can use the formula for the hypergeometric distribution, which is:

P(X ≥ 3) = [C(10,3) * C(10,2)] / C(30,5) + [C(10,4) * C(10,1)] / C(30,5) + [C(10,5)] / C(30,5)

Where C(n,r) is the number of ways to choose r items from a set of n items.

formula is that we need to consider three different cases: drawing exactly 3 white marbles, drawing exactly 4 white marbles, and drawing all 5 white marbles. For each case, we calculate the probability of drawing the required number of white marbles and the probability of drawing the remaining marbles (non-white marbles), and then multiply them together. Finally, we add up the probabilities for all three cases to get the total probability of drawing 3 or more white marbles.

Using the formula, we get:

P(X ≥ 3) = [(C(10,3) * C(20,2)) + (C(10,4) * C(20,1)) + C(10,5)] / C(30,5)

= [(120 * 190) + (210 * 20) + 252] / 142506

= 0.209

Therefore, the probability of drawing 3 or more white marbles when 5 marbles are drawn from the bag without replacement is 0.209.

using the hypergeometric distribution formula, we can calculate the probability of drawing 3 or more white marbles from a bag containing 5 red marbles, 6 blue marbles, 10 white marbles, and 9 yellow marbles when 5 marbles are drawn without replacement. The probability is 0.209.

Answer:

x = -2 and y = 2.5

Step-by-step explanation:

using elimination method:

y = 0.25x + 3                 call this equation '1'

x = -4y + 8

bring 4y on its own

4y = -x + 8                       call this equation '2'

multiply '1' by 4:

4y = x + 12                      call this equation '3'

add '2' and '3'

8y = (-x + x) + 20

8y = 20

y = 20/8 = 2.5.

go back to '1'

we have y = 0.25x + 3

              2.5 = 0.25x + 3

 subtract 3 from both sides

2.5 - 3 = 0.25x

-0.5 = 0.25x

multiply both sides by 4

-2 = x

x = -2

now put both y =2.5 and x = -2 into '2' to see if all is fine

4y = -x + 8

4(2.5) = -(-2) + 8

10 = +2 + 8

10 = 10

so x = -2 and y = 2.5

To find the equation of the tangent line, we need to find the derivative of both x and y with respect to t and evaluate them at t = 1 to get the slope of the tangent line. The equation of the line tangent to the curve at the point determined by t = 1 is y = (5/4)(x - 3) + 2.

dx/dt = 2t + 2

dy/dt = 3t^2 + 2t

At t = 1, dx/dt = 4 and dy/dt = 5

So the slope of the tangent line is m = dy/dx = (dy/dt)/(dx/dt) = 5/4

Now we need to find the point on the curve where t = 1.

x = t^2 + 2t = 1^2 + 2(1) = 3

y = t^3 + t^2 = 1^3 + 1^2 = 2

Therefore, the point on the curve where t = 1 is (3, 2)

Using the point-slope form of a line, we can write the equation of the tangent line as:

y - 2 = (5/4)(x - 3)

Simplifying:

y = (5/4)x - (7/2)

So the equation of the line tangent to the curve at the point determined by t = 1 is y = (5/4)x - (7/2).

A curve is described by the parametric equations x = t^2 + 2t and y = t^3 + t^2. An equation of the line tangent to the curve at the point determined by t = 1 is given by the formula y = m(x - x1) + y1, where m is the slope, and (x1, y1) is the point of tangency.

First, find the point of tangency (x1, y1) by plugging t = 1 into the parametric equations:
x1 = (1)^2 + 2(1) = 3
y1 = (1)^3 + (1)^2 = 2

Next, find the derivatives of x and y with respect to t:
dx/dt = 2t + 2
dy/dt = 3t^2 + 2t

Now, find the slope m by dividing dy/dt by dx/dt at t = 1:
m = (dy/dt) / (dx/dt) = (3(1)^2 + 2(1)) / (2(1) + 2) = (5/4)

Finally, plug the slope m and point (x1, y1) into the equation of the tangent line:
y = (5/4)(x - 3) + 2

So, the equation of the line tangent to the curve at the point determined by t = 1 is y = (5/4)(x - 3) + 2.

Let's visualize the parallelogram-shaped land with sides of 240m and 160m. We know that the distance between the 240m sides is 40m. Let's denote this distance as "d".

To find the distance between the 160m sides, we can use the concept of similar triangles. The triangles formed by the sides of the parallelogram are similar. In the smaller triangle, the base is 160m, and the corresponding side in the larger triangle is 240m. Similarly, the height of the smaller triangle is "d", and the corresponding side in the larger triangle is 40m. Using the property of similar triangles, we can set up the following proportion:

160m / 240m = d / 40m

Simplifying the proportion, we get:

2/3 = d / 40m

Cross-multiplying, we have:

d = (2/3) * 40m

Calculating the value, we find:

d = 26.67m

Therefore, the distance between the 160m sides of the parallelogram-shaped land is approximately 26.67m.

8 cups = 64cm

From the catalog, we know that a stack of 2 cups is 16 cm tall, and a stack of 4 cups is 20 cm tall.

To find the height of a stack of 8 cups, we can use proportionality.

Let x be the height, in cm, of a stack of 8 cups. Then, we can set up the following proportion:

2 cups / 16 cm = 8 cups / x cm

Cross-multiplying, we get:

2 cups * x cm = 16 cm * 8 cups

Simplifying, we get:

2x = 128

x = 64 cm

Therefore, the height of a stack of 8 cups is 64 cm.

It takes 7 hours to travel 385 miles at a constant speed.

To solve this problem, we need to use the direct variation formula, which states that distance traveled is directly proportional to time spent driving. This means that if we double the time spent driving, the distance traveled will also double.

Using this formula, we can set up a proportion to find the answer. We know that the car travels 330 miles in 6 hours, so we can write:

330/6 = 385/x

Where x is the time it takes to travel 385 miles.

To solve for x, we can cross-multiply and simplify:

330x = 2310

x = 7


It's important to note that this problem assumes that the car maintains a constant speed throughout the entire trip. If the car speeds up or slows down at any point, the distance traveled and time spent driving will not follow a direct variation relationship.

We have to given that;

In triangle ,

Perpendicular side = 9 mm

Base = 2 mm

Since, We know that;

The Pythagorean theorem states that the square of the hypotenuse of a right triangle equals the sum of the squares of its two opposite sides.

Hence, By Pythagoras theorem we get;

⇒ Hypotenuse² = Perpendicular² + Base²

⇒ c² = 9² + 2²

⇒ c² = 81 + 4

⇒ c = √85

Thus, The length of the hypotenuse is,

⇒ c = √85

The coordinates of the point B of vector is B ( -5 , -3 )

Given data ,

To find the coordinates of the terminal point B, we can start with the initial point of vector AB and add its components.

Initial point of AB: (-9, 8)

x-component of AB: 4

y-component of AB: -11

To find the coordinates of the terminal point B, we add the x-component and y-component to the corresponding coordinates of the initial point.

x-coordinate of B = x-coordinate of initial point + x-component of AB

x = -9 + 4

x = -5

y-coordinate of B = y-coordinate of initial point + y-component of AB

y = 8 + (-11)

y = -3

Hence , the coordinates of the terminal point B are (-5, -3)
