1 answer:

3 0

You pick only one letter, so the possible outcomes are:
A,C,O,M,D,T, I, N

if you need to probability of each outcome:
A: 2/13 (there are 2 As and a total of 13 letters)
C: 2/13
O: 3/13

ans so on.
use your calculator to change each fraction to a decimal if needed.

A rectangular poster is to contain 722 square inches of print. the margins at the top and bottom of the poster are to be 2 inche

Delvig [45]

Let
x ----------> the height of the whole poster
y ----------> the width of the whole poster

We need to minimize the area A=x*y

we know that
(x-4)*(y-2)=722
(y-2)=722/(x-4)
(y)=[722/(x-4)]+2

so
A(x)=x*y--------->A(x)=x*{[722/(x-4)]+2}
Need to minimize this function over x > 4

find the derivative------> A1 (x)
A1(x)=2*[8x²-8x-1428]/[(x-4)²]

for A1(x)=0
8x²-8x-1428=0
using a graph tool
gives x=13.87 in

(y)=[722/(x-4)]+2

y=[2x+714]/[x-4]-----> y=[2*13.87+714]/[13.87-4]-----> y=75.15 in

the answer is
the dimensions of the poster will be
the height of the whole poster is 13.87 in
the width of the whole poster is 75.15 in

Answer:

y = -5/3x + 4/3z

Step-by-step explanation:

5x + 3y = 4z

3y = -5x + 4z

y = -5/3x + 4/3z
