How much did McCandless weigh when he died?

Answer:

y = -1/5 x + 2

Step-by-step explanation:

y = 5x - 4

m = 5

Slope of perpendicular = -1/5

Equation of perpendicular:

y = mx + b

y = -1/5 x + b

Use point (15, -1) for x and y, and solve for b.

-1 = -1/5(15) + b

-1 = -3 + b

b = 2

Equation of perpendicular:

y = -1/5 x + 2

Answer:

20, 23, 26, 29

Step-by-step explanation:

Step-by-step explanation:

let's multiply the first equation by 2 and the second equation by -3, and then we add them together :

26x - 12y = 4

-9x +12y = 30

-------------------------

17x 0 = 34

x = 2

and now we use one of the original equations to solve for y :

3×2 - 4y = -10

6 - 4y = -10

-4y = -16

y = 4

the solution is (2, 4).

The value of x is 200 for the given two equations x-y=80 and 3/5=y/x using the equating process.

The two equations are given as:

x - y = 80 -------- Equation 1

3/5 = y/x --------- Equation 2

First, we need to solve the equation 2. Here two terms x and y are unknown. But if we can make two equations in the terms of one variable then we can easily find the values of x and y. From equation 2, we get:

y/x = 3/5

y = 3x/5 ------ (equation 3)

Now, we can substitute this equation 3 for y into Equation 1:

x - y = 80

x - (3x/5) = 80

Multiplying both sides by 5:

5x - 3x = 400

2x = 400

x = 200

Therefore, we can conclude that the value of x is 200.

The expected value in a binomial situation with n = 18 and π = 0.60 is E(X) = np = 18 * 0.60 = 10.8.

In a binomial situation, the expected value, denoted as E(X), represents the average or mean outcome of a random variable X. It is calculated by multiplying the number of trials, denoted as n, by the probability of success for each trial, denoted as π.

In this case, we are given n = 18 and π = 0.60. To find the expected value, we multiply the number of trials, 18, by the probability of success, 0.60.

n = 18 (number of trials)

π = 0.60 (probability of success for each trial)

To find the expected value:

E(X) = np

Substitute the given values:

E(X) = 18 * 0.60

The variance of the scores in a sample tends to be less than or equal to the variability of the scores in the population from which the sample was obtained.

When we take a sample from a population, it is expected that the variability within the sample will be somewhat representative of the variability in the population. However, due to the random nature of sampling, there is a chance that extreme scores or outliers in the population may not be fully captured in the sample, resulting in slightly reduced variability. Therefore, the sample variance typically provides an estimate that is close to the population variance but is generally smaller due to the potential sampling variability.

The choice of the type and dimensions of the measuring geometry in TPA (Thermal Performance Analysis) is influenced by several factors such as measurement accuracy, sensitivity to heat transfer variations, sample size, spatial resolution, and practical considerations.

Here are the steps to explain why the dimensions of the measuring geometry are often 25mm and 50mm probe in TPA:

Step 1: Measurement Accuracy and Resolution

The dimensions of the measuring geometry should be chosen to ensure sufficient accuracy and resolution in the measurements. Larger probe dimensions may provide more accurate results due to better averaging of temperature variations, while smaller probe dimensions can provide higher resolution for detecting localized temperature variations. Therefore, a balance needs to be struck between accuracy and resolution.

Step 2: Sensitivity to Heat Transfer Variations

The choice of probe dimensions in TPA is also influenced by the sensitivity of the system to heat transfer variations. Larger probe dimensions can capture a wider area and average out local variations, providing a more representative measurement of the overall heat transfer performance. On the other hand, smaller probe dimensions can detect localized variations and provide more detailed information about specific regions.

Step 3: Sample Size and Spatial Resolution

The dimensions of the measuring geometry should be suitable for the size and scale of the system being analyzed. If the sample size is large or if there are significant spatial variations in the heat transfer, larger probe dimensions may be more appropriate to cover a representative area. However, if the sample size is small or if there are fine-grained spatial variations, smaller probe dimensions can provide higher spatial resolution.

Step 4: Practical Considerations

Practical considerations also play a role in determining the dimensions of the measuring geometry. For instance, the size of the available equipment or probes may limit the choice of dimensions. Standardized probe sizes, such as 25mm and 50mm, are commonly used in TPA, as they are readily available and widely accepted in the industry.

The choice of the type and dimensions of the measuring geometry in TPA, such as 25mm and 50mm probes, is determined by factors such as measurement accuracy, sensitivity to heat transfer variations, sample size, spatial resolution, and practical considerations. The specific dimensions should strike a balance between accuracy and resolution, considering the characteristics of the system being analyzed and the available equipment.

Big O notation focuses on the worst-case scenario analysis, which is 0(n) for a simple search. It’s a reassurance that a simple search will never be slower than O(n) time.

Imagine that you're a teacher with a student named Ram. You want to find his records, so you use a simple search algorithm to go through your school district's database.

You know that a simple search takes O(n) times to run. This means in the worst case, you'll have to search through every single record to find Ram

After a simple search, you find that Ram records are the very first entry in the database. You don't have to look at every entry.

Did this algorithm take O(n) time Or did it take O(1) time because you found Ram records on the first try?

In this case, 0(1) is the best-case scenario – you were lucky that Ram records were at the top. But Big O notation focuses on the worst-case scenario, which is 0(n) for a simple search. It’s a reassurance that a simple search will never be slower than O(n) time.

The variables of interest are grades or study habits, height would not be a factor that affects these variables. Therefore, selecting the four tallest students would not be a random sample.

Suppose you are assigned the number 1, and the other students in your statistics class call out consecutive numbers until each person in the class has his or her own number. To get a random sample of four students from your statistics class, you could use a random number generator to select four numbers between 1 and the total number of students in the class.

Then, you would choose the students with those corresponding numbers as your random sample.(a) The first four students walking into the classroom would not necessarily form a random sample because there could be some sort of ordering or trend to the way students arrive that could bias the sample.

  1b) multiply both sides by -1

  2a) 2x+4

  2b) 2x

  2c) P = 2x+4; A = 2x

Step-by-step explanation:

To solve equations, you take advantage of the properties of equality and of identity elements.

The multiplicative identity element is 1. (Multiplying by 1 does not change the value of a number or expression.) The product of a number and its reciprocal is the multiplicative identity element.

The multiplication property of equality tells you that you can multiply both sides of an equation by the same value, and the value of the variable remains the same. (The equal sign remains true.)

Of course, division by 'a' is the same as multiplication by 1/a.

__

1a) We have 2x on the left. We want 1x on the left. The properties discussed above say we can multiply both sides of the equation by the multiplicative inverse of 2 and the result will be what we're after.

  (1/2)(2x) = (1/2)(17) . . . . multiply both sides by 1/2 (equivalently, divide by 2)

  x = 17/2

1b) The coefficient of x is -1. The reciprocal of that is also -1. So, we can multiply this equation by -1 to get what we're after.

 (-1)(-x) = (-1)(9) . . . . multiply both sides by -1

  x = -9
