Comparison is an effort to compare two or more objects in terms of shape or size, or number  

Proportional Comparisons / Directly proportional are comparisons of two or more numbers where one number increases, the other numbers also increase at the same rate  

 Can be formulated  

[tex]\displaystyle \frac {x1} {y1} = \frac {x2} {y2}[/tex]

 so that if:  

 x = 2  

 then  

[tex]\displaystyle y ={ \frac {y} {x} \times \: 2}[/tex]

 While the reversal value comparison / inversely proportional is the comparison of two or more numbers where one number increases, the other number decreases in value  

or when one value decreases at the same rate that the other increases  

Can be formulated  

[tex]\displaystyle \frac {x1} {y2} = \frac {x2} {y1}[/tex]

so that if:  

 x = 2  

 then  

[tex]\displaystyle y = \frac {x} {y} \times \: 2[/tex]

Michelle wants to save $150

The length of the rectangle with a perimeter of 36 meters and a length that is 2 meters more than three times the width is 14 meters.

The perimeter of a rectangle is twice the sum of its length and width. According to the question, the perimeter of the rectangle is 36 meters, and the length (L) is 2 meters more than three times the width (W). We can express this relationship as follows: L = 3W + 2.

The formula for the perimeter (P) of a rectangle is P = 2L + 2W.

Using the given perimeter of 36 meters, we can set up the equation as 2(3W + 2) + 2W = 36.

Simplifying this equation, we find that 8W + 4 = 36, and thus W = 4 meters.

Substituting the value of W back into the equation for L gives us L = 3(4) + 2, which means the length of the rectangle is 14 meters.

The calories in a 21-oz iced tea that is originally 78 calories in a 13-oz serving, multiply the calories per ounce by the new serving size for a total of 126 calories.

The 13-oz iced tea contains 78 calories. To find the calories in a 21-oz iced tea:

Calculate the calories per ounce: 78 calories ÷ 13 oz = 6 calories/oz

Multiply the calories per ounce by the 21-oz serving size: 6 calories/oz × 21 oz = 126 calories in a 21-oz iced tea

Answer:

5%

Step-by-step explanation:

to work out what percent 17 is out of 340 we can formulate an equation

so 340(x%)=17

when we solve for x we get 5

Answer:

5 people

Step-by-step explanation:

Let

The total cost was $1400, which was to be divided equally among the members going. Then,

y = 1400 / x [1]

Prior to the trip, 3 members decided not to go. The cost per person increased by $105.

y + 105 = 1400 / (x - 3)

(y + 105) . (x - 3) = 1400 [2]

We replace [1] in [2],

(1400/x + 105) . (x - 3) = 1400

1400 - 4200/x + 105x -315 = 1400

- 4200/x + 105x = 315

(- 4200 + 105x²)/x = 315

- 4200 + 105x² = 315 x

105x² - 315x - 4200 = 0

When we solve this quadratic equation using the quadratic formula, we get x₁ = 8 and x₂ = -5. Only the positive x has sense.

The people that went to the expedition was x - 3 = 8 - 3 = 5.

To find the length of the ladder, we can use the property of right triangles. The length of the ladder is 10 feet.

To find the length of the ladder, we can use the property of right triangles. Let's assume the length of the ladder is 'L'.

According to the given information, the distance from the ground to the top of the ladder is 2 feet less than the length of the ladder. So, the height of the triangle formed by the ladder, the building, and the ground is L - 2.

The distance from the bottom of the ladder to the building is given as 6 feet. Using the Pythagorean theorem, we can set up the following equation: (L-2)^2 + 6^2 = L^2

Simplifying the equation, we get L^2 - 4L + 4 + 36 = L^2, which simplifies further to 40 = 4L. Dividing both sides by 4, we get L = 10.

Therefore, the length of the ladder is 10 feet.

Given a Poisson distribution with 0.05 flaws/sq ft and 10 sq ft panels, each car has a 60.65% chance of no flaws.

The probability of at least 1 car with flaws is 99.35%.

Considering only 1 car with flaws, the final probability of at most 1 car with flaws is 90.2%.

Probability of at most 1 car with flaws: 90.2%

Here's how to calculate the probability that at most 1 car out of 10 has any surface flaws, given the Poisson distribution parameters:

1. Define parameters:

Mean flaws per square foot (λ) = 0.05

Area of plastic panel per car (A) = 10 square feet

Number of cars (N) = 10

2. Calculate probability of no flaws:

Probability of no flaws in one car (P(X=0)) = e^(-λA) = e^(-0.0510) ≈ 0.6065

3. Calculate probability of 1 car with flaws (complementary probability):

Probability of at least 1 car with flaws (1 - P(no flaws in all cars))

P(X ≥ 1) = 1 - (P(X=0))^N = 1 - (0.6065)^10 ≈ 0.9935

Probability of exactly 1 car with flaws (P(X=1)) = N * P(X=0) * (1-P(X=0))^N-1

≈ 10 * 0.6065 * (1 - 0.6065)^9 ≈ 0.3869

4. Final probability:

Probability of at most 1 car with flaws (P(X ≤ 1)) = P(X=0) + P(X=1) ≈ 0.6065 + 0.3869 ≈ 0.9934

The probability that at most 1 car out of 10 has any surface flaws is approximately 90.2%.

Therefore, Given a Poisson distribution with 0.05 flaws/sq ft and 10 sq ft panels, each car has a 60.65% chance of no flaws.

The probability of at least 1 car with flaws is 99.35%.

Considering only 1 car with flaws, the final probability of at most 1 car with flaws is 90.2%.

The probable question may be: The number of surface flaws in plastic panels used in the interior of automobile has a Poisson distribution with a man of 0.05 flaws per square foot of plastic panel. Assume an automobile interior contains 10 square feet of plastic panel. If 10 cars are sold to a rental company, what is the probability that at most 1 car has any surface flaws?

a. The probability of no surface flaws in an auto's interior is approximately 0.7408.

b. The probability of none of the 10 cars having any surface flaws is approximately 0.0498.

c. The probability of at most 1 car having any surface flaws is approximately 0.9631.

a. Probability of no surface flaws:

Calculate the lambda parameter: The lambda parameter for the Poisson distribution represents the expected number of flaws, which is calculated as the mean flaws per square foot multiplied by the total area.

In this case, [tex]\lambda[/tex] = 0.03 flaws/sq ft * 10 sq ft = 0.3 flaws.

Use the Poisson probability formula: The probability of no flaws (x = 0) in a Poisson distribution is given by [tex]e^{(-\lambda)[/tex].

Plugging in lambda = 0.3, we get

P(x = 0) = [tex]e^{(-0.3)[/tex] ≈ 0.7408.

b. Probability of none of the 10 cars having flaws:

Treat each car as an independent event: Since the flaws are random and independent for each car, we can treat each car as a separate event with the same probability of no flaws (0.7408) calculated in part (a).

Calculate the combined probability: To get the probability of none of the 10 cars having flaws, we simply multiply the individual probabilities.

P(no flaws in all 10 cars) = [tex](0.7408)^{10[/tex] ≈ 0.0498.

c. Probability of at most 1 car having flaws:

Calculate probabilities for 0 and 1 flaws: We need the probabilities of 0 flaws (already calculated in part (a)) and 1 flaw (x = 1) to determine the probability of at most 1 flaw.

Probability of 1 flaw: Using the Poisson formula again,

P(x = 1) = [tex]\lambda[/tex] * [tex]e^{(-\lambda)[/tex] = 0.3 * [tex]e^{(-0.3)[/tex] ≈ 0.2222.

Probability of at most 1 flaw: This includes both scenarios with 0 and 1 flaws. P(at most 1 flaw) = P(0 flaws) + P(1 flaw) = 0.7408 + 0.2222 ≈ 0.9631.

Final answer:

Ava can capture the chip on square 72 by using the +30 change card once to reach 66, and then the +1 change card six times to reach the final value of 72.

Explanation:

Ava's game piece is on square number 36, and she wants to capture a chip on square number 72. By using the change cards, Ava needs to adjust her position from 36 to 72 with the change cards provided. The change cards are: -10, +30, -1, +1, and -2. To determine if Ava can capture the chip, we need to see if we can use the cards to add up to a net change of +36 (since 72 - 36 = 36).

By analyzing the cards, we can use the +30 card once, which would take Ava's position from 36 to 66. Next, she can use the +1 card six times to go from 66 to 72. Ava does not need to utilize the -10, -1, or -2 cards as they would move her backwards. Therefore, Ava can indeed capture the chip using the change cards provided.

The steps Ava should follow are:

Use the +1 card six times to move from 66 to 72.
