The correlation between two observed variables is -0.84. from this, it can be concluded that the relationship between the two variables is strong but inverse (opposite direction).
<h3>What is correlation?</h3>
Correlation is one of the several measures of the linear statistical relationship between two random variables, indicating both the strength and direction of the relationship.
The correlation coefficient denoted by r is used to measure the strength and direction of a linear relationship between two random variables. of two variables.
The r value is between 0 and 1 and the closer to 1 indicates the strength of the relationship Also, when the r is negative, it is an indication that both variables move in the opposite direction.
Therefore, the correlation between two observed variables is -0.84. from this, it can be concluded that the relationship between the two variables is strong but inverse.

Answer:
![f=2887.93Hz](https://tex.z-dn.net/?f=f%3D2887.93Hz)
Explanation:
Given data
Length L=2.9 cm=0.029m
Speed of sound v=335 m/s
to find
Fundamental frequency f
Solution
As we know that frequency is given as:
f=v/λ
![f=\frac{v}{4L}\\ f=\frac{335m/s}{4(0.029m)} \\ f=2887.93Hz](https://tex.z-dn.net/?f=f%3D%5Cfrac%7Bv%7D%7B4L%7D%5C%5C%20f%3D%5Cfrac%7B335m%2Fs%7D%7B4%280.029m%29%7D%20%5C%5C%20f%3D2887.93Hz)
No, if the car were moving sideways, then the forces used would be on the horizontal axis. So the weight equation would be extraneous, unless one is determining the net force through an inclined plane
Answer:
Explanation:
Pulmo - lungs
cutan - skin
artery - heart
Frogs breath through their skin oxygenating blood pumped from the heart.
The pulmonary artery connects heart and lungs in humans.
That would be 110/22, which is 5 hours
