Use technology or a z-score table to answer the question. the expression p(z< 1.87) represents the area under the standard normal curve below the given value of z. what is p(z< 1.87)?

The expression represents the area under the standard normal curve below the given value of .

Now,

.

Where represents the cumulative density function.

The value of represents the area under the standard normal distribution curve between and .

Using normal tables or technology,

.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
