Answer:
A.P+C=O
A(2).P+C=$7.00
B.A (1) that expression doesnt give the amount for both sets of cookiea all together its just shown as a letter.A(2) its shows p+c as $7.00 showing thats how much for both sets of cookies instead of having a letter to represent the amount payed.
PS:hope this helped good luck !
.48 is the answer you have to do .08 times 6
Answer:
Option B is correct
Step-by-step explanation:
Given is a cos funciton.
Period = 3
Max = 20 and minimum =0
Hence centre line is y = 1/2 (max+min)
i.e. y =10 is the central line
Let the funciton be of the form
y = a cos (bx+C)+d
We got d = 10...i
Period =3
Hence b =
... ii
Amplitude = a = distance of max from central line = 20-10 =10...iii
Since reflection over x axis, sign of a =negative
a=-10
Since no horizontal shift, c=0 ... iv
Put to gether the function is

Let X be the weekly incomes of a large group of executives. The weekly incomes of a large group of executives follows Normal distribution with mean $2000 and standard deviation $100.
μ =2000, σ =100
We have to find z score for income $2100 i.e x=2100
Z = 
= 
Z = 100/100
Z = 1
The z score for income $2100 is 1
It’s 9 cause 9x3=27
hhhhhhhhhhhhhhhhh
