The speed of an airplane is 275 mi/h relative to the air. The wind is blowing due north with a speed of 25 mi/h. In what direction should the airplane head in order to arrive at a point due west of its location?
Answer:
Step-by-step explanation:
The free-body diagram of the information given in the question is attached in the image below.
Using the property of Vector Right Triangle:
cos θ = adjacent/hypotenuse
cos θ = 25 mi/h / 275 mi/h
cos θ = 0.0909
θ = cos⁻¹ (0.0909)
θ = 84.79°
Therefore, the airplane should head in the direction of S 84.79° W to reach the desired location.

The container will be made from cardboard. How many
square inches of cardboard are needed to make one
container? Assume there are no overlapping areas.
The number of square inches of cardboard that are needed to make one
the container is 18.
We have,
The volume of the triangular prism.
= Area of the triangle x height
Now,
Height = 6 in
And,
To find the area of a triangle, we can use Heron's formula.
A = √(s(s-a)(s-b)(s-c))
where s is the semi-perimeter of the triangle, calculated as:
s = (a + b + c) / 2
In this case, the side lengths of the triangle are 3.2 in, 3.2 in, and 2 in.
Let's calculate the area using Heron's formula:
s = (3.2 + 3.2 + 2) / 2 = 4.2
A = √(4.2(4.2 - 3.2)(4.2 - 3.2)(4.2 - 2))
A = √(4.2 x 1 x 1 x 2.2)
A = √(9.24)
A ≈ 3.04 square inches
Now,
The volume of the triangular prism.
= Area of the triangle x height
= 3.04 x 6
= 18.24 in²
Now,
Area of one cardboard.
= 1² in²
= 1 in²
Now,
The number of square inches of cardboard that are needed to make one
container.
= The volume of the triangular prism / Area of one cardboard
= 18.24 in² / 1 in²
= 18.24
= 18
Therefore,
The number of square inches of cardboard that are needed to make one
the container is 18.

Find the circumference of the circle use 3.14 for
Pi Round to the nearest hundred put the answer in cm
Need ASAP if u don’t know the answer don’t answer
Answer:
47.1 cm
Step-by-step explanation:
The circumference of a circle is denoted by C = 2πr, where r is the radius.
Here, we see that the given radius is 7.5, so r = 7.5 cm. We also are given that we need to use the approximation 3.14 for π, so plug all these into the formula:
C = 2πr
C = 2 * 3.14 * 7.5 = 47.1
To round this to the nearest hundredth... well, there's no hundredth place, so we can leave this as is or just write 47.10 cm.
Thus, the circumference is 47.1 cm.
find the sum of the series 1 12 13 14 16 18 19 112 where the terms are reciprocals of the positive integers whose only prime factors are 2s and 3s.
the sum of the series is 8/3. The series consists of reciprocals of positive integers whose only prime factors are 2s and 3s.
In other words, each term of the series can be expressed as a fraction of the form 1/n, where n is a positive integer that can be factored into only 2s and 3s. For example, the first term of the series is 1/1, the second term is 1/2, and the fourth term is 1/4.
To find the sum of the series, we can first list out the terms and their corresponding values:
1/1 = 1
1/2 = 0.5
1/3 = 0.333...
1/4 = 0.25
1/6 = 0.166...
1/8 = 0.125
1/9 = 0.111...
1/12 = 0.083...
and so on.
We can see that the terms of the series decrease in value as n increases, so we can use this fact to estimate the sum of the series. For example, we can take the sum of the first few terms to get an idea of how large the sum might be:
1 + 0.5 + 0.333... + 0.25 = 2.083...
We can see that the sum is greater than 2, but less than 3. To get a more accurate estimate, we can add a few more terms:
2.083... + 0.166... + 0.125 + 0.111... = 2.486...
We can continue adding terms in this way to get a more and more accurate estimate of the sum. However, it is not easy to find a closed-form expression for the sum of the series.
Alternatively, we can use a formula for the sum of a geometric series to find the sum of the series. A geometric series is a series of the form a + ar + ar^2 + ... + ar^n, where a is the first term and r is the common ratio between terms. In our series, the first term is 1 and the common ratio is 1/2 or 1/3, depending on whether n is even or odd. Therefore, we can split the series into two separate geometric series:
1 + 1/2 + 1/8 + 1/32 + ... = 1/(1 - 1/2) = 2
1/3 + 1/12 + 1/48 + 1/192 + ... = (1/3)/(1 - 1/2) = 2/3
The sum of the two geometric series is the sum of the original series:
2 + 2/3 = 8/3
Therefore, the sum of the series is 8/3.

The temperature in a hotel is 21 °C.
The temperature in the hotel is 26,7°C warmer than at the top of the mountain.
The temperature at the top of the mountain is 3.2°C colder than at the bottom of the mountain.
Work out the temperature at the bottom of the mountain.
The temperature at the bottom of the mountain is 50.9 °C.
Let's work through the given information step by step to find the temperature at the bottom of the mountain.
The temperature in the hotel is 21 °C.
The temperature in the hotel is 26.7 °C warmer than at the top of the mountain.
Let's denote the temperature at the top of the mountain as T_top.
So, the temperature in the hotel can be expressed as T_top + 26.7 °C.
The temperature at the top of the mountain is 3.2 °C colder than at the bottom of the mountain.
Let's denote the temperature at the bottom of the mountain as T_bottom.
So, the temperature at the top of the mountain can be expressed as T_bottom - 3.2 °C.
Now, let's combine the information we have:
T_top + 26.7 °C = T_bottom - 3.2 °C
To find the temperature at the bottom of the mountain (T_bottom), we need to isolate it on one side of the equation. Let's do the calculations:
T_bottom = T_top + 26.7 °C + 3.2 °C
T_bottom = T_top + 29.9 °C
Since we know that the temperature in the hotel is 21 °C, we can substitute T_top with 21 °C:
T_bottom = 21 °C + 29.9 °C
T_bottom = 50.9 °C
Therefore, the temperature at the bottom of the mountain is 50.9 °C.

You have also set up a card game in which a player picks a card from a standard deck of 52 cards. The player wins if these two events occur together: E1, in which the card drawn is a black card, and E2, in which the card drawn is a numbered card, 2 through 10.
Question 1
What is the probability of getting a black card and a numbered card? Calculate the probabilities P(E1) and P(E2) as fractions.
The probability of getting a black card and a numbered card is 9/26.
To calculate the probability of getting a black card (E1), we need to determine the number of black cards in a standard deck of 52 cards.
There are 26 black cards in total, which consist of 13 spades (black) and 13 clubs (black).
Therefore, the probability of drawing a black card (P(E1)) is:
P(E1) = Number of favorable outcomes / Total number of possible outcomes
P(E1) = 26 / 52
Simplifying this fraction, we get:
P(E1) = 1/2
So the probability of drawing a black card is 1/2.
To calculate the probability of drawing a numbered card (E2), we need to determine the number of numbered cards (2 through 10) in a standard deck.
Each suit (spades, hearts, diamonds, clubs) contains one card for each numbered value from 2 to 10, totaling 9 numbered cards per suit.
Therefore, the probability of drawing a numbered card (P(E2)) is:
P(E2) = Number of favorable outcomes / Total number of possible outcomes
P(E2) = 36 / 52
Simplifying this fraction, we get:
P(E2) = 9/13
So the probability of drawing a numbered card is 9/13.
To calculate the probability of both events occurring together (getting a black card and a numbered card), we multiply the individual probabilities:
P(E1 ∩ E2) = P(E1) × P(E2)
P(E1 ∩ E2) = (1/2) × (9/13)
Simplifying this fraction, we get:
P(E1 ∩ E2) = 9/26
Therefore, the probability of getting a black card and a numbered card is 9/26.

Answer: If in a prior study, a sample of 200 people showed that 40 traveled overseas last year, then n= 385
If no estimate of the sample proportion is available , then n= 601
Step-by-step explanation:
Let p be the prior population proportion of people who traveled overseas last year.
If p is known, then required sample size = \(n=p(1-p)(\dfrac{z^*}{E})^2\)
z-value for 95% confidence = 1.96
E = 0.04 (given)
\(p=\dfrac{40}{200}=0.2\)
\(n=0.2(1-0.2)(\dfrac{1.96}{0.04})^2=384.16\approx385\)
Required sample size = 385
If p is unknown, then required sample size = \(n=0.25(\dfrac{z^*}{E})^2\)
, where E = Margin of error , z* =critical z-value.
z-value for 95% confidence = 1.96
E = 0.04 (given)

cm
88cm88, start text, c, m, end text, not
33
cm
33cm33, start text, c, m, end text.
How will this length increasing affect the mean and median?
Using their concepts, we have that the mean will be increased and the median will remain constant.
What is the mean of a data-set?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.
The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile, which is the middle value of the distribution.
The largest value is the 7th observation, therefore it will be included in the calculation of the mean.
Since this observation have an increased value, the sum of all observations will be increased while the number of observations remains constant,
So the mean will be increased.
Hence, for a distribution of 7 observations, we have that:
The first three observations are the first half.
The 4th observation is the median.
The last three observations are the second half.
Here only the last observation changes, not the fourth, hence the median remains constant.
