Find the z
scores for 25000 and 28000.
z1=( x –
average)/ standard deviation =( 25000-30000)/ 2000 = -2.5
z2=( x –
average)/ standard deviation =( 31000-30000)/ 2000 = 0.5
Find the
corresponding P(z).
P (z1) = 0.00621
P (z2) = 0.15866
Subtract the
probabilities to find the probability for the range,
(25000<= x
<=28000)
<span>P(x) = 0.15866-0.00621
= 0.1524</span>



keeping that template in mind, the g(x) function is just a translated version of f(x), it is translated upwards by 2 units, namely D = 2.

T-Shirts=$15
Gift Card=100
So you can solve it this way:
it says that the gc had $100, and at the end of the day it only has 10.
So it means she spend $90 in T-Shirts.
And each T-Shirt is $15.
15x=90
15(60)=90
She bought 6 T-Shirts
