Your main choices here are (1) a calculator with statistical functions and (2) a table of z-scores.
(a) On my TI-83 Plus calculator I typed in normcdf(-1000, 0.92). The calculator returned the value 0.821. This is approx. 8/10 of the total area under the std normal curve.
(b) I typed in normcdf(-1000, -1.26) and got 0.104
(c) I typed in normcdf(-1000, -0.64) and got 0.261
(d) I typed in normcdf(-1000, -1.09) and got 0.138

Answer:
The rate of change of a function with respect to a variable.
Step-by-step explanation:
For example: The slope of a constant value (like 3) is always 0. The slope of a line like 2x is 2, or 3x is 3 etc. and so on.
Step-by-step explanation:
Hey, there!!
you number is: 81/625
We know that,
81=9×9
and
625=25×25
and............................................................
9×9 means 9^2
and 25×25 means 25^2
so, the exponential form of the question is,
=
{we simply find exponential form by finding their fraction}
