Rohen decided to collect data to determine if the size of a student's home and the student's age are correlated. He determined t

he data to have a correlation coefficient of 0.02. What does this r value indicate? No correlation A strong, positive correlation A weak, positive correlation A negative correlation

Answer:

A correlation coefficient of 0.02 indicates that the data are not correlated.

Step-by-step explanation:

0.02 is very close to zero and tells you that there is no linear relationship between the two variables.

The constant-pressure specific heat of air at 25°C is 1.005 kJ/kg. °C. Express this value in kJ/kg.K, J/g.°C, kcal/ kg. °C, and
Mice21 [21]

Answer:

In kJ/kg.K - 1.005  kJ/kg degrees Kalvin.

In  J/g.°C  -  1.005 J/g °C

In kcal/ kg °C  0.240 kcal/kg °C

In Btu/lbm-°F   0.240 Btu/lbm degree F

Step-by-step explanation:

given data:

specific heat of air = 1.005 kJ/kg °C

In kJ/kg.K

1.005 kJ./kg °C = 1.005 kJ/kg degrees Kelvin.

In  J/g.°C

1.005 kJ./kg °C \times 1000/1kJ \times (1kg/1000 g) = 1.005J/g °C

In kcal/ kg °C

1.005 kJ./kg °C \times \frac{1 kcal}{4.190 kJ} = 0.240 kcal/kg °C

For   kJ/kg. °C to Btu/lbm-°F  

Need to convert by taking following conversion ,From kJ to Btu, from kg to lbm and from degrees C to F.

1.005 kJ./kg °C \times \frac{1 Btu}{1.055 kJ} \times \frac{0.453 kg}{1 lbm} \times \frac{5/9 degree C}{1 degree F} = 0.240 Btu/ lbm / degree F

1.005 kJ/kg C =  0.240 Btu/lbm degree F

Lines K and L are parallel,and the measure of angle ABC is 19 degrees
Scorpion4ik [409]

Answer:

A. Because the measure of the angle BCD is 19 \° and the angles BCD  and ECF are Vertical angles. Therefore, they are congruent ( m\angle BCD=m\angle ECF =19\°)

B.  m\angle BCD=19\°

Step-by-step explanation:

<h3> <em><u>The missing figure is attached.</u></em></h3><h3 />

You can observe in the figure that the parallel lines k and l are intersected by a another line m (this is a transversal).

Let's begin with PART B:

Observe that the angles ABC and BCD are located inside the parallel lines and they alternate sides of the transversal. Therefore, we can determine that these angles are "Alternate Interior Angles".

Since the lines k and l are parallel, we know that the Alternate Interior Angles are congruent. Then:

m\angle ABC=m\angle BCD=19\°

Now we can solve the PART A.

Observe the figure.

Since the angle BCD  and the angle ECF share the same vertex, they are "Vertical angles" and, therefore, they are congruent:

m\angle BCD=m\angle ECF =19\°

Suppose you were exploring the hypothesis that there is a relationship between parents’ and children’s party identification. Wou
alukav5142 [94]

Answer:

No

It could be purely due to chance.

Step-by-step explanation:

A population is defined as the whole group which has the same characteristics. For example a population of the college belongs to the same college . But a sample may be an element of a population.

So it is not necessary for a population to have the same characteristics as the sample.

But it is essential for the sample to have at least one same characteristics as the population.

So we would not be correct in inferring that such a relationship also exists in the population.

It is a hypothesis which can be true or false due to certain conditions or limitations as the case maybe.

For example in a population of smokers some may be in the habit of taking cocaine. But a sample of cocaine users does not mean the whole population uses it.

It could be purely due to chance if we find out that there is a relationship between parents’ and children’s party identification in the population.
