Marcus likes to go for a run each morning before school. He recorded the number of minutes he spends running and the distance he covers. The scatter plot represents the data he collected

Marcus Likes To Go For A Run Each Morning Before School. He Recorded The Number Of Minutes He Spends

Answers

Answer 1

Answer:

D. 0.85

Step-by-step explanation:

The data points in the scatter plot are closer to each other along the line of best fit, this means that there is a strong positive association between minutes and distance and therefore, the correlation coefficient would be relatively closer to 1.

The correlation is positive since both variables tend to increase together in the same direction.

Therefore, the best estimate of the correlation coefficient out of the given options would be 0.85

La temperatura exterior era de 8 grados a la medianoche. La temperatura bajó 5 grados durante cada una de las siguientes 3 horas. ¿Cuál era la temperatura a las 3 a.m.?​

Answers

Answer:

A las 3 AM la temperatura era de -7 grados.

Step-by-step explanation:

Dado que la temperatura exterior era de 8 grados a la medianoche, y la temperatura bajó 5 grados durante cada una de las siguientes 3 horas, para determinar cuál era la temperatura a las 3 a.m. se debe realizar el siguiente cálculo:

8 - (3 x 5) = X

8 - 15 = X

-7 = X

Por lo tanto, a las 3 AM la temperatura era de -7 grados.

A random sample of 10 subjects have weights with a standard deviation of 12.7363 kg. What is the variance of their​ weights?

Answers

Answer:

Variance, V = 162.2133 kg²

Step-by-step explanation:

Given the following data;

Standard deviation = 12.7363 kg.

To find the the variance of their weights?

Mathematically, standard deviation is equal to the square root of variance.

[tex]Sd = \sqrt{V}[/tex]

Where;

Sd is the standard deviation of the sample.

V is the variance of the sample.

Substituting into the formula, we have;

[tex]12.7363 = \sqrt{V}[/tex]

Taking the square of both sides, we have;

[tex]12.7363^{2} = V [/tex]

Answers

i actually dont know this

Yes, they are quite similar. the p-value obtained using the theory-based method (p < 0.0001) agree with that obtained using the randomization/simulation - based method (p < 0.0001)

P- value is the probability of obtaining a value of test statistic more extreme in the direction of alternative hypothesis than the observed one. In easy words if p -value < level of significance we reject H0 in favor of H1.

Here:

p-value < 0.0001 => we reject H0.

If the statistical software renders a p value of 0.000 it means that the value is very low, with many "0" before any other digit.

So the interpretation would be that the results are significant, same as in the case of other values below the selected threshold for significance.

Therefore, yes they are quite similar.

Step-by-step explanation:

Recall: the exterior angle theorem of a triangle states that an exterior angle is equal to the sum of the two opposite interior angles of a triangle.

❌Option 1 CANNOT be true

Rationale:

m<1 is an exterior angle of triangle ∆ABC and ∆EBC, so based on the exterior angle theorem of a triangle, m<1 = m<3 + m<4 or m<1 = m<ABC + m<5

❌Option 2 CANNOT be true.

Rationale:

m<5 ≠ m<3 - m<2

❌Option 3 CANNOT be true.

Rationale:

m<6 ≠ m<3 - m<2

✅Option 4 is CORRECT.

Calculate the number of vertices in a full 5-ary tree with 35 internal vertices.
Also, find out the number of leaves

Answers

Answer:

Step-by-step explanation:

With 35 internal nodes, there are 5*35=175 vertices out of which are 175-35=140 leaves.

The number of vertices in a full 5-ary tree is 175.

The number of leaves is 140.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of full trees = 5

Number of internal vertices = 35

Now,

The number of vertices.

= 5 x 35

= 175

Now,

The number of leaves.

= 175 - 35

= 140

Thus,

Number of vertices is 175.

Number of leaves is 140.

In psychology, aptitude tests are designed to measure the ability to learn. Questions are designed to be age appropriate so as not to be biased toward age due to knowledge acquired. In this study, an aptitude test is given on the skills necessary to use apps on a smart phone. An aptitude test with a maximum score of 150 is given to measure the ability to learn how to use apps on a smartphone.
The regression line for the predicted value of aptitude given age is as follows:
Aptitude = 111.3 - 1.13*Age
Find the expected aptitude test score for a person whose age is 15 years. Your answer should be rounded to the nearest whole number.

Answers

Answer:

The expected aptitude test score for a person whose age is 15 years is 94.

Step-by-step explanation:

Aptitude formula in function of age:

The aptitude A in function of age a is given by:

[tex]A(a) = 111.3 - 1.13a[/tex]

Find the expected aptitude test score for a person whose age is 15 years.

This is A when a = 15. Thus, finding the numeric value of the function:

[tex]A(a) = 111.3 - 1.13a[/tex]

[tex]A(15) = 111.3 - 1.13(15) = 94.35[/tex]

Rounding to the nearest whole number, 94.

In this question, we first explain the expected aptitude test after that we calculate its value.

The test of aptitude allows employers to assess the skills of a candidate via a variety of test formats. Required to test your ability to do things and react to working circumstances is tested. It includes, among others, problem-solving, prioritization as well as numeracy skills.When a score of 100% again for a perfect aptitude test, as well as a score of 80% or greater is considered a good person with the minimum acceptable score is deemed to be between 70% and 80%.

Given:

[tex]\to \bold{Aptitude = 111.3 - 1.13*Age}[/tex]

[tex]\to \bold{Age= 15 \ years}\\\\[/tex]

Putting the age value into the Aptitude equation to calculate its value:

[tex]\bold{= 111.3 - 1.13*(15)}\\\\\bold{= 111.3 - 16.95}\\\\\bold{=94.35 \approx 94} \\\\[/tex]

Therefore, For a person 15 years of age 94, the anticipated test score for aptitude.

The probability distribution for a random variable x is given in the table X: -5,-3,-2,0,2,3 Probability: .17,.13,.33,.16,.11,.10 Find the probability that -2<_x<_2

Answers

Answer:

0.6 probability that [tex]-2 \leq x \leq 2[/tex]

Step-by-step explanation:

The probability distribution is given in the table.

Probability that x is between -2 and 2.

Between -2 and 2, inclusive, we have -2, 0 and 2. So

[tex]P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2)[/tex]

From the table:

[tex]P(X = -2) = 0.33, P(X = 0) = 0.16, P(X = 2) = 0.11[/tex]. So

[tex]P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2) = 0.33 + 0.16 + 0.11 = 0.60[/tex]

Step-by-step explanation:

(b) The sample space is { boy, boy, girl}

So, the probability is 1/3.
