A fisherman yanks a fish vertically out of the water with an acceleration of 2.5! !! using very light fishing line that has a br

Artyom0805 [142]

Two forces act on the fish, and these are:

1) Its weight mg, downwards and

2) pressure in the string, T, upwards which is 22 N when the string breaks.
In the result of these two forces, the fish had an acceleration of 2.5 m/s^2 in the upward way.

So, T - mg = m*2.5

=> m = T / (2.5 + g)

=> m > 22 / (2.5 + 9.8) ( when the string snaps )

=> m > 1.79 kg.

As a result, the mass of the fish is more than 1.79 kg as the line has been broken.

The correlation between height and weight among men age 18-74 in the U.S. is about 0.40. Say whether each conclusion below follo

zzz [600]

Answer:

Options a, b, c are correct.

Step-by-step explanation:

First let's see the equation that governs the statement, which is the following:

$r = \frac{cov (x, y)}{\sqrt{var(x) var (y)} }$

Therefore, reading options a, b, c are correct.

Since from the formula we have the correlation coefficient of two variables x and y and here it shows us the correlation between x, y and y, x is the same.

This means that the 0.4 correlation implies a moderate but positive relationship between the two variables.

that is, the highest or lowest value of one variable implies a highest or lowest value of the other variable, respectively.
