Estimated probability=number of outcomes in question/divided by total number of trials
ep=102/300
ep=51/150 (34%)
Answer:
- Calculus texts: 600
- History texts: 0
- Marketing texts: 0
Step-by-step explanation:
Each Calculus text returns $10/2 = $5 per unit of shelf space. For History and Marketing texts, the respective numbers are $4/1 = $4 per unit, and $8/4 = $2 per unit. Using 1200 units of shelf space for 600 Calculus texts returns ...
$5/unit × 1200 units = $6000 . . . profit
Any other use of units of shelf space will reduce profit.
You find a common denominator (the bottom one) and then add the numerator (the top) but you don't add the denominator, you just make it the same
14 boxes per hour
60/5=12
12*3=36
60/6=10
10*5=50
50-36=14
Hello There!
Dividing a fraction is the same thing as multiplying by its reciprocal.
This means that
÷
is the same as multiplying
by
.
So basically when you divide you leave the first fraction alone but the second fraction in this case, 5/12 you would flip the number on top and the number on bottom to 12/5.
HAVE A GREAT DAY!
