Answer:
<em>105 pieces of jewlery </em>
Step-by-step explanation:
42%=0.42
then 0.42*250=105
Assuming a Poisson Distribution then probability it receives "k" calls is:
where
<h3>
Answer: a = f/p</h3>
===============================================
Explanation:
We'll solve for 'a' doing these two steps in this exact order
- Multiply both sides by 'a'
- Divide both sides by p
We do this because we're following PEMDAS in reverse to isolate the variable we want.
The steps look like this
p = f/a
pa = f
a = f/p
Note how ultimately the 'a' and p variables swap places when going from p = f/a to a = f/p
Answer:
49
Step-by-step explanation:
Every time you multiply both sides of a rectangle by a number x, its area if multiplied by 
.
In our example:
Area of a rectangle = width . length
width = 4
length = 7
= 4 . 7 = 28
When you multiply both sides by 7:
width = 4 . 7 = 28
length = 7 . 7 = 49
= 28 . 49
= 1372
/ = 1372 / 28 = 49 = 
Both sides multiplied by 7 => Area multiplied by 
Got it?
;-)
She can get 21 portions. Since 2/3 and 42/3 already share the same denominator, all you need to do is divide 42 by 2 to get 21.
