1. The functions are the same because each of the function has equations that are modeled after the horse diving into the water.

2. Given t = 20s, so using the equation modeled for Seb, we have

h(20) = -16(20^2) + 16(20) +18

After evaluating it we get -6062ft which is not possible since we cannot get a height in negative and jumping off at a height of 6062ft if it was in positive it wouldn't be done by a sane person.

3. Putting the value of t as 0 in the equation we get,

h(0) = -16(0^2) + 16(0) + 18

After evaluating it, we get 18ft and in this situation, we can say that in 0 seconds that is when the horse had not yet dived, the horse was at a height of 18ft.

4 a. Taking the value of h as 18 in Sabri's equation, we get

18 = -16(t - 0.5)^2 + 22

18 = 16t^2 - 4 + 22            (After solving {t - 0.5}^2)

t^2= 18 + 4 - 22/ 16

t^2= 0

t = 0seconds

b. The maximum height of Sabrina's height was 18ft, since this is the initial height of the horse diving booth.

What are functions?
In mathematics, a function is an expression, rule, or law that establishes a relationship between an independent variable and a dependent variable. To put it simply, a function is a type of rule that produces one output for every input it receives. Here, y=x2 serves as an illustration. A single output for y results from any input for x. Since x is the input value, we would state that y is a function of x.

Upper Control Limit for R Chart: UCL = D4 * R-Bar , UCL = 2.114 * 1.000, UCL ≈ 2.115 cm. Therefore, the correct answer is 2.115 cm(d).

To calculate the upper control limit for the R Chart, we need to use the following formula:

Upper Control Limit (UCL) = D4 * R-Bar

Where:

- D4 is a constant value based on the sample size (n=5 in this case).

- R-Bar is the average range of the samples, which is given as 1.000 cm.

The value of D4 for a sample size of 5 is 2.114. (You can find this value in statistical reference tables.)

Now, we can calculate the UCL:

UCL = D4 * R-Bar

   = 2.114 * 1.000

   = 2.114 cm

Rounding to 3 decimal places, the upper control limit for the R Chart is 2.114 cm.

The following statement "If a regression model has high bias, it is unlikely that collecting more data to train/build the model will increase its performance on a validation or test set" is absolutely true.

If a regression model has high bias, it means that it is oversimplified and unable to capture the complexity of the data. Collecting more data may not necessarily improve the model's performance on a validation or test set because the model is already too simple to effectively model the data. In fact, increasing the amount of data may actually make the bias worse by further emphasizing the oversimplified nature of the model. To improve the performance of a model with high bias, it is usually necessary to use a more complex model or introduce additional features to the model.

If a regression model has high bias, it means the model is oversimplified and does not capture the underlying patterns in the data. Collecting more data to train/build the model is unlikely to increase its performance on a validation or test set in terms of SSE (Sum of Squared Errors), MSE (Mean Squared Error), or R2 (R-squared) because the model's simplicity prevents it from learning the necessary complexity to accurately represent the data. To improve the model's performance, it's important to consider reducing the bias by using more complex models or incorporating additional features.

The metric system of measurement is based on the number 10.

This system is also known as the International System of Units (SI) and is used in most countries around the world. In the metric system, various units of measurement are defined as multiples or fractions of a base unit, which is defined for each quantity being measured. For example, the base unit for length is the meter, and the base unit for mass is the kilogram. Prefixes such as kilo-, centi-, and milli- are used to indicate multiples or fractions of the base unit, based on factors of 10. For example, a kilometer is 1000 meters, a centimeter is 1/100 of a meter, and a milligram is 1/1000 of a gram. This makes the metric system easy to use and convert between units, as well as consistent and universally recognized.

Step-by-step explanation:

The sample of size 36 provides the strongest evidence to reject H0 in favor of Ha

B) = 27, S = 4.

An testing whether the population mean (μ) is less than 30 based on a sample of size 36. The test statistic commonly used in this scenario is the t-statistic which follows a t-distribution.

The formula for the t-statistic is

t = (X - μ) / (S / √(n))

where:

X is the sample mean

μ is the hypothesized population mean under H0

S is the sample standard deviation

n is the sample size

A smaller t-statistic value indicates stronger evidence against H0 and in favor of Ha.

calculate the t-statistic for each sample result

A) X= 28, S = 6, n = 36

t = (28 - 30) / (6 / √(36)) = -2 / (6/6) = -2

B) X= 27, S = 4, n = 36

t = (27 - 30) / (4 / √(36)) = -3 / (4/6) = -4.5

C) X = 32, S = 2, n = 36

t = (32 - 30) / (2 / √(36)) = 2 / (2/6) = 6

D) X = 26, S = 9, n = 36

t = (26 - 30) / (9 / √(36)) = -4 / (9/6) = -8/3 ≈ -2.67

Comparing the t-statistics,  that option B) with t = -4.5 gives the strongest evidence against H0. A more negative t-value indicates a larger deviation from the hypothesized mean of 30, which supports the alternative hypothesis that the true mean is less than 30.

False.

In random assignment of cases to experimental groups, there is no guarantee that the groups would have identical dependent variable measures in a pretest.

Random assignment aims to minimize systematic differences between the groups by randomly assigning participants to different conditions. However, it does not ensure that the groups will be exactly identical in their pretest measures of the dependent variable.

The purpose of random assignment is to create comparable groups, reducing the likelihood that any preexisting differences between participants would systematically bias the results. By randomly assigning participants, researchers increase the probability that any differences between groups after the intervention is due to the manipulation of the independent variable rather than preexisting differences.

To address potential pretest differences, researchers often employ techniques like randomization and blocking. Randomization involves randomly assigning participants to different conditions, while blocking involves dividing participants into subgroups based on certain characteristics (e.g., age, gender) and then randomly assigning participants within each subgroup to different conditions. These techniques aim to create groups that are as similar as possible at the outset of the experiment.

Answer:

17.97 units

Step-by-step explanation:

We are given that KL is parallel to NM and that LM = 45 units and m∠M = 50 degrees. We are also given that KN is perpendicular to NM and that NL is perpendicular to LM.

Using trigonometry, we can find the lengths of NL and KN:

sin(50) = NL/LM

NL = LMsin(50) = 45sin(50) ≈ 34.47

cos(50) = KN/NM

KN = NMcos(50) = 45cos(50) ≈ 34.47

To find KL, we can use the fact that NL is parallel to KL, so we have similar triangles KLN and LMN:

KL/NL = LM/LN

KL/34.47 = 45/cos(50)

KL ≈ 17.97

Therefore, KL is approximately 17.97 units.
