There are three students in Mrs. Johansen's class who like sightseeing. We cannot estimate the total number of students in the class based solely on this information.

It is not possible to accurately predict the total number of students in Mrs. Johansen's class based on the information provided. However, we can make an estimate based on the assumption that the three students who responded to the survey are representative of the entire class.

It is impossible to create an accurate projection of the total number of pupils in Mrs. Johansen's class without knowing more about the survey or the class.

However, assuming that the survey was distributed to all students in the class, we may create an approximation based on the proportion of students who stated that their favourite holiday was sightseeing. For example, if we believe that the three students who stated that their favourite holiday was touring reflect 25% of the whole class (i.e., one-fourth of the class), we may estimate that the class has about 12 students.

The pattern of the sequence is "add increasing multiples of 9 starting with 1."

To find the pattern in the sequence 10, 11, 21, 32, follow these steps:
1. Identify the differences between consecutive terms:
  11 - 10 = 1
  21 - 11 = 10
  32 - 21 = 11
2. Notice that the differences are increasing by 9 (10 - 1 = 9 and 11 - 10 = 1).
3. Based on this observation, the pattern can be described as adding a value that increases by 9 each time:

The 95% confidence interval for μ is (80.52, 82.68).

To find the 95% confidence interval for the population mean (μ), we can use the following formula

CI = X ± z* (σ / √n)

where X is the sample mean, σ is the population standard deviation (unknown), n is the sample size, and z* is the critical value from the standard normal distribution corresponding to the desired confidence level (in this case, 95%).

The critical value z* can be found using a standard normal distribution table or calculator, or using a statistical software. For a 95% confidence level, the z* value is 1.96.

Plugging in the values given, we get

CI = 81.6 ± 1.96 × (5.4 / √100)

Simplifying this expression, we get

CI = 81.6 ± 1.08

66 ways in the triple rooms, 28 ways in the double rooms

Step-by-step explanation:

In total: 8 people;

There are 2 triple rooms, so 3 people can live in one triple room:

In the first triple room:

8×7×6 = 336 / 3×2×1 = 56 ways (we have to divide the number of ways by the factorial, because the order of people doesn't matter)

In the second triple room:

5×4×3 = 60 / 3×2×1 = 10 ways (since we can't choose the same people from the first triple room)

In total: 56+10 = 66 ways

Now, double rooms:

Ir the first double room:

8×7 = 56 / 2×1 = 28 ways

In the second double room:

6×5 = 30 / 2×1 = 15 ways

The probability that both the first and second student studied = p²

To find the probability that both the first and second students studied when two different students are randomly selected, we can use the multiplication rule of probability.

The multiplication rule of probability states that if the probability of event A is p(A), and the probability of event B, given that event A has occurred, is p(B|A), then the probability of the joint occurrence of A and B is given by p(A and B) = p(A) × p(B|A).

So, if we let A be the event that the first student studied, and B be the event that the second student studied, then we need to find the probability of the joint occurrence of A and B.

We can assume that the probability that any student studied is equal to some value p, and the probability that any student didn't study is equal to q = 1 - p. Since there are only two possibilities for each student (studied or not studied), then p + q = 1. So, we can use the complement rule of probability to write:

p(A) = probability that the first student studied = p, and

p(not A) = probability that the first student didn't study = q = 1 - p,

p(B|A) = probability that the second student studied, given that the first student studied = p, and

p(B|not A) = probability that the second student studied, given that the first student didn't study = p.To find the probability that both the first and second student studied, we need to find the probability of the joint occurrence of A and B. Using the multiplication rule, we get:

p(A and B) = p(A) × p(B|A) = p × p = p².

The sale price of the computer after a single reduction of 30% is $455.

The double reduction (25% off and then 5% off) and the single reduction of 30% are different.

The sale price after the double reduction is $463.13, while the sale price after a single reduction of 30% is $455.

What is a percentage?

The percentage is a way of expressing a fraction or proportion out of 100. It is commonly used in many different areas such as finance, math, science, and everyday life.

First, we need to find the sale price of the computer after the double reduction.

When the price of all computers in the store is reduced by 25%, the sale price of the computer that originally cost $650 becomes:

Sale price after first reduction ,

=> 650 - 25% 0f 650

=> 650 - [tex]\frac{25}{100}\times[/tex]650 = $ 487.5

Then, when the sale price is reduced by an additional 5%, the sale price of the computer becomes:

Sale price after double reduction

=> 487.5 - 5% of 487.5

=>  487.5 - [tex]\frac{5}{100}\times[/tex]487.5 = $463.13

Therefore, the sale price of the computer after the double reduction is $463.13.

Next, we need to find the sale price of the computer after a single reduction of 30%.

When the original cost of the computer is reduced by 30%, the sale price becomes:

Sale price after single reduction ,

=> 650- 30% of 650

=>  650 - [tex]\frac{30}{100}\times[/tex] = $455

Therefore, the sale price of the computer after a single reduction of 30% is $455.

The double reduction (25% off and then 5% off) and the single reduction of 30% are different.

The sale price after the double reduction is $463.13, while the sale price after a single reduction of 30% is $455.

Area of yard

Therefore, Mya needs to plant 150 square feet of grass to cover the entire yard

A rectangular yard is a type of outdoor space that is often used for gardening, outdoor activities, or as a place for relaxation. To calculate the area of a rectangular yard, you need to know its dimensions, which are typically expressed in feet or meters. The area of a rectangular yard can be found by multiplying its length by its width. The formula for the area of a rectangle is A = L x W, where A represents the area, L represents the length, and W represents the width.

70, degree, since the helicopter ascended at an angle of 20°

20 and the two angles add up to 90°

90.Now we can use the tangent function to find x. Tangent is defined as the opposite side (x) divided by the adjacent side (d), so we have:

Solving for x, we get:

x = d * tan(70°)

We know that d = 3.43.43, point, 4 kilometers, so we can plug that in and calculate:

x = 3.43.43, point, 4 * tan(70°)

x ≈ 11.211.2 kilometers (rounded to one decimal place)

To conclude that quadrilateral LMNO is a parallelogram, we need either ML ∥ NO, LO ≅ MN, or ML ⊥ LO.

Since LO ∥ MN, we know that ∠LON = ∠OMN and ∠NOM = ∠LMO. To conclude that LMNO is a parallelogram, we need to show that opposite sides are parallel and equal in length.

The following statements would be sufficient to conclude that LMNO is a parallelogram:

ML ∥ NO: If ML is parallel to NO, then ∠LMO = ∠NOM, and since ∠NOM = ∠LMO, we have ∠LMO = ∠NOM = ∠NLO = ∠OML. Therefore, opposite angles are equal, and LMNO is a parallelogram.

LO ≅ MN: If LO is equal in length to MN, then we have LO = MN and ∠LON = ∠OMN. Therefore, triangle LON is congruent to triangle MON by the side-angle-side (SAS) congruence criterion. This implies that ∠LNO = ∠MNO and ∠LON = ∠MON. Since ∠LNO + ∠LON = 180° and ∠MNO + ∠MON = 180°, we have ∠LNO = ∠MON and ∠LON = ∠MNO. Therefore, opposite angles are equal, and LMNO is a parallelogram.

ML ⊥ LO: If ML is perpendicular to LO, then ∠LMO = 90° and ∠NOM = 90°. Therefore, opposite angles are equal, and LMNO is a parallelogram.
