Answer:

The length of  bank side ,s = \sqrt{3} unit.

The length of hypotenuse, h= 2 unit.

Step-by-step explanation:

Given in 30-69-90 triangle

We know that

tan\theta= \frac {perpendicular}{base}

sin\theta=\frac { perpendicular}{ hypotenuse}

When\theta=30^{\circ}

sin\theta= \frac{1}{h}

sin30^{\circ}=\frac {1}{h}

sin30^{\circ}=\frac{1}{2}

Therefore,\frac{1}{h} =\frac{1}{2}

By cross multiply we get

h=2

tan30^{\circ}=\frac{1}{s}

tan30^{\circ}=\frac {1}{\sqrt{3}}

\frac{1}{s} =\frac{1}{\sqrt{3}}

By cross multiply we get

s=\sqrt{3}

Hence, the length of side of bank, s=\sqrt{3} unit

Length of hypotenuse ,h=2 unit.

Does cold salty water sink or rise along the ocean floor as deep as a current​
rewona [7]

Answer:

In cold regions, such as the North Atlantic Ocean, ocean water loses heat to the atmosphere and becomes cold and dense. When ocean water freezes, forming sea ice, salt is left behind causing surrounding seawater to become saltier and denser. Dense-cold-salty water sinks to the ocean bottom.

levacccp [35]

Answer: 34 degrees of freedom should be used to find the p-value of the test .

Step-by-step explanation:

Degrees of Freedom relates to the maximum number of independent values, that have independence to vary in the sample.

Given : When testing the difference between two population means and the population variances are unknown and unequal, the degrees of freedom are calculated as 34.7.

But degree of freedom must be an integer , so we find the greatest integer less than equal to the calculated degree of freedom.

i.e. [df]=[34.7]= 34

Thus , 34 degrees of freedom should be used to find the p-value of the test .
