What is the simplified value of the expression below? a.4.8 b.19.2 c.22.1 d.57.6

Option C i.e. 22.1 is correct

Step-by-step explanation:

The given expression follows pemdas rule

PEMDAS:

P for Paranthesis

E for Exponents

M for Multiplication

D for division

A for Addition

S for Subtraction

Given :24 -12 /2 *3.2

=  24-12/2*3.2     [Multiplication]

= 24- 12/6.4      [Division]

=24-1.875         [Subtraction]

=22.125

So the answer is C. 22.1

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
