An injured monkey sits perched on a tree branch 3.0 m above the ground, while a wildlife veterinarian is kneeling down in the bu
Irina18 [472]

here in the given situation if monkey starts free fall at the same instant when veterinarian shoots towards it then we know that vertical component of motion of monkey and the dart will be same as under gravity

so here the dart will always hit the monkey because they both moves under same acceleration

so here for the angle we can use

tan\theta = \frac{H}{L}

now we have

H = 3 m

L = 87.5 m

now we will have

tan\theta = \frac{3}{87.5}

tan\theta = 0.034

\theta = 1.96 degree

so angle will be 1.96 degree above the ground

The deviation of a value (x) from the mean of the sample divided by the standard deviation (s)of the sample is known as the "z"
Ugo [173]

Answer:

true.

Explanation:

z-score gives an idea of how far the value of data is from the mean point. Basically is the measure of a standard deviation below or above the mean.

More the deviation of the data from the mean more is the standard deviation.

Z-score or value is calculated by the expression given below:

     z = \dfrac{x-\mu}{\sigma}

  x is the value

 μ is the mean

 σ is the standard deviation

Hence, the statement given is true.
