Alenkinab [10]

Answer:

It is impossible to draw two different triangles with these criteria.

Step-by-step explanation:

The 3,4,5 triangle is a Pythagorean triplet, but if it was said to be 6,8,10, then yes two different triangles can be made, same with any other multiple of a 3,4,5 right triangle. The 3,4,5 triangle is in its reduced form causing there to be no other triangles that can be made that still function as a triangle through the theorem of triangles where the hypotenuse has to be bigger than either side length.

Find the value of z such that 0.76980.7698 of the area lies between −z−z and z. round your answer to two decimal places.
babunello [35]
P(-z<Z<z)=0.7698
P(0<Z<z)=0.7698/2=0.3849
P(Z<0)=0.5
P(Z<z)=P(Z<0)+P(0<Z<z)=0.5+0.3849=0.8849
Using the z-table, the z-score that corresponds to probability of 0.8849 is z=1.20
