Construct a box plot from the given data. Scores on a statistics test: 83,72,91,73,74,51,62,52,76,93

Answer: $135

Step-by-step explanation:

    We know that:

         Selling price = [tex](100 - \text{Loss}\%)(\frac{\text{Cost Price}}{100})[/tex]

    Using the given cost price and loss%, we can solve.

         Selling Price = [tex](100 - \text{Loss}\%)(\frac{\text{Cost Price}}{100})[/tex]

         Selling Price = (100 - 10)([tex]\frac{\text{150}}{100}[/tex])

         Selling Price = (90) * (1.5)

         Selling Price = $135

    This means the selling price of the dress is $135.

The object will have a height of 100 feet after 100 seconds.

The equation for the height of the object in feet after T seconds is H(T) = A(T - h)2 + k, where A and h are constants. Given that the object has a height of 0 feet after 10 seconds, and a maximum height of 200 feet at 0 seconds, we can solve for A and h.

We know that H(0) = 200, so k = 200.

We also know that H(10) = 0, so A(10 - h)2 + 200 = 0. Solving for A, we get A = -(h2 + 200) / 102.

Now we have an equation with two unknowns, A and h, so we can use substitution to solve for h. We can substitute -(h2 + 200) / 102 for A in our original equation, and solve for h. This gives us h = 10.

We now know A = -(102 + 200) / 102 = -20.

So, our equation for the height of the object in feet after T seconds is H(T) = -20(T - 10)2 + 200.

To find the height of the object after 100 seconds, substitute 100 for T in the equation. This gives us H(100) = -20(100 - 10)2 + 200 = 100.

Let's call the distance we are looking for "x". We can use the sine function, which relates the opposite side of a right triangle to its hypotenuse:

sin(51°) = opposite/hypotenuse

We know that the hypotenuse is the length of the ladder, which is 3.8m. We can solve for the opposite side (x) by rearranging the equation:

x = sin(51°) * 3.8m

x ≈ 2.98m

So the bottom of the ladder is about 2.98 meters away from the wall. Rounded to the nearest tenth, the answer is 3.0 meters.

(a) (6, H, 7) is not a possible outcome because the sum of the two numbers rolled on the number cube cannot be 7 if the first number rolled is 6.

(b) (T, 3, 4) is a possible outcome because the first outcome is tails, the second outcome is 3, and the third outcome is 4.

(c) (6, H, 6, T) is not a possible outcome because the third outcome cannot be both 6 and T at the same time.

(d) (1, T, 1) is a possible outcome because the first and third outcomes are both 1 and the second outcome is tails.

(e) (H, H, 3) is not a possible outcome because the third outcome cannot be 3 if the first two outcomes are both heads.

What is Probability?

Probability is a branch of mathematics in which the chances of experiments occurring are calculated. It is by means of a probability, for example, that we can know from the chance of getting heads or tails in the launch of a coin to the chance of error in research.

Since each of the three people orders a different flavor, the first person has 6 choices, the second person has 5 choices (since one flavor has already been chosen), and the third person has 4 choices (since two flavors have already been chosen). The total number of outcomes is the product of these numbers:

6 × 5 × 4 = 120

Therefore, there are 120 possible outcomes.

(part 1) There are 10 options for the first digit, 9 options for the second digit (since one digit has already been chosen), and 8 options for the third digit (since two digits have already been chosen). The total number of combinations is the product of these numbers:

10 × 9 × 8 = 720

Therefore, there are 720 possible locker combinations.

(part 2) If you absolutely choose 9 as your first digit, then there are only 9 options for the first digit. The second and third digits can still be any of the remaining 9 digits (since digits cannot repeat). Therefore, the number of possible combinations is:

1 × 9 × 8 = 72

The theoretical probability of getting HH on two coin flips is (1/2) × (1/2) = 1/4 = 0.25. The experimental probability of getting HH after 100 trials is 25/100 = 0.25. Since the experimental probability is equal to the theoretical probability, we can say that the experimental probability of getting HH is equal to the theoretical probability.

The possible outcomes of rolling a standard number cube are 1, 2, 3, 4, 5, and 6. The possible outcomes of flipping a coin are heads (H) or tails (T).

The GCF (greatest common factor) of the first two terms of the polynomial 3p^(3)+9p^(2)+5p+15 is 3p^(2). This is because both terms have a common factor of 3p^(2) that can be factored out.

The GCF of the last two terms of the polynomial is 5. This is because both terms have a common factor of 5 that can be factored out.

Therefore, the polynomial can be factored as follows:

3p^(2)(p+3) + 5(p+3)

Now, we can factor out the common factor of (p+3) to get the final factored form of the polynomial:

The distribution is  X ~ N(46, 19), the probability that a randomly selected student's time will be between 42 and 44 minutes is 0.04147. the probability that the average time studying for the 50 students is between 42 and 44 minutes is 0.1601.

a. X ~ N(46, 19)

b. e is not defined in the problem, so it does not have a distribution.

c. z ~ N(0, 1) (standard normal distribution)

d. To find the probability that one randomly selected student's time will be between 42 and 44 minutes, we first standardize the values:

z = (44 - 46) / 19 = -0.1053

z = (42 - 46) / 19 = -0.2105

Using a standard normal table or calculator, we can find the area under the standard normal curve between these two z-scores:

P(-0.2105 < z < -0.1053) = 0.04147

Therefore, the probability that a randomly selected student's time will be between 42 and 44 minutes is 0.04147.

e. To find the probability that the average time studying is between 42 and 44 minutes, we need to use the central limit theorem. Since we have a large enough sample size (n = 50) and the population standard deviation is known, we can use the following formula to standardize the sample mean:

z = (x - μ) / (σ / √n)

Substituting the given values:

z = (44 - 46) / (19 / √50) = -0.7443

z = (42 - 46) / (19 / √50) = -1.4886

Using a standard normal table or calculator, we can find the area under the standard normal curve between these two z-scores:

P(-1.4886 < z < -0.7443) = 0.1601

Therefore, the probability that the average time studying for the 50 students is between 42 and 44 minutes is 0.1601.

f. The total study time for the 50 students follows a normal distribution with mean 5046 = 2300 minutes and standard deviation √5019 ≈ 39.70 minutes. To find the probability that the total study time is more than 2200 minutes, we standardize the value:

z = (2200 - 2300) / 39.70 = -2.5189

Using a standard normal table or calculator, we can find the area under the standard normal curve to the right of this z-score:

P(z > -2.5189) = 0.99411

Therefore, the probability that the randomly selected 50 students will have a total study time more than 2200 minutes is 0.99411.

g. The assumption of normality is necessary for parts e) and f) because we are using the normal distribution and the central limit theorem to approximate the probabilities. Without the normal assumption, we would need to use different methods for probability calculations.

h. We need to find the least total time that corresponds to the top 15% of the distribution. Using a standard normal table or calculator, we can find the z-score that corresponds to the 85th percentile:

z = 1.0364

We can then use the formula for the total study time:

x = μ + z(σ / √n)

Substituting the given values:

x = 4650 + 1.0364(19*√50) ≈ 4652.78

Therefore, the least total time that a group can study and still receive a sticker is approximately 4652.78 minutes.

The area of the shaded shape WXZY s equal to 381.4 cm².

Mathematically, the area of a sector can be calculated by using this formula:

Area of sector = θπr²/360

Where:

In order to determine the area of the shaded shape WXZY, we would have to subtract the area of sector OYZ from the area of the sector OWX.

Area of sector OWX = 75 × 3.14 × 32²/360 = 669.87 cm²

Area of sector OYZ = 75 × 3.14 × 21²/360 = 288.49 cm²

Area of shaded shape WXZY = Area of sector OWX - Area of sector OYZ

Area of shaded shape WXZY = 669.87 cm² - 288.49 cm²

The value of x is 18 and y is 16. The solution has been obtained by using concept of similar triangles.

If two triangles have the same number of corresponding sides and corresponding angles, they are said to be similar. Similar figures are objects that have the same shape but various sizes, like two or more figures.

We are given that in ΔABC and ΔBDC,

∠ABC ≅ ∠BDC  (right angles)

BC ≅ BC  (common side)

∠ACB ≅ ∠BCD (common angle)

So,  ΔABC ≅ ΔBDC.

We know that in similar triangles, the ratio of the corresponding sides is same.

So,

AC / BC = BC / CD

Now, by substituting the given values in the relation, we get,

⇒18/a = a/16
