Answer:

The value za/2 needed to constrict a confident interval with level 87% is 1.51

Step-by-step explanation:

At 87% confidence level the z is ,

α= 1 - 87%

= 1 - 0.87

= 0.13

α/ 2 = 0.13 / 2

= 0.065

Zα/2 = Z0.065

= 1.51 ( Using z table )

What is the length of a hypotenuse of a triangle if each of its legs is 4 units

azamat

Answer:

$\boxed{c = 5.7 units}$

Step-by-step explanation:

<u><em>Using Pythagorean Theorem:</em></u>

=> $c^2 = a^2+b^2$

Where c is hypotenuse, a is base and b is perpendicular and ( a, b = 4)

=> $c^2 = 4^2+4^2$

=> $c^2 = 16+16$

=> $c^2 = 32$

Taking sqrt on both sides

=> c = 5.7 units
