(a) the area to the left of zequals=negative 1.45−1.45 is nothing. (round to four decimal places as needed.)

a)

b)

c)

d)

Step-by-step explanation:

To find : Determine the area under the standard normal curve that lies ?

Solution :

a) In between Z=-1.45 and Z=1.45

i.e.

Now,

Using Z-table,

b) In between Z=-1.63 and Z=1.63

i.e.

Now,

Using Z-table,

c) In between Z=-1.48 and Z=1.48

i.e.

Now,

Using Z-table,

d) In between Z=-1.37 and Z=1.37

i.e.

Now,

Using Z-table,

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
