X=9.9 I believe (sry if I’m wrong)
Answer:
(a+dd)/10
Step-by-step explanation:
let be a the amount of atlases and dd the amount of dictionaries.
<em>Mrs. Marcus combines her atlases and </em><em>dictionaries</em>
then, total amount of books=a+dd
<em>then divides them among 10 different </em><em>tables</em>
total books/10= (a+dd)/10
45 minutes.(1 hour / 60 minutes)=45/60 hours=3/4 hours.
rate=paints boats/ time (hour)=340 boats / (3/4) hour=
=(340 boasts*4)/3 hour=453.333... boats/hour≈453.33 boat/hour.
Hi,thank you for posting your question here at Brainly.
Probability is a numerical value that represents a fraction of a whole. Since there are 4 samples indicated in row X, then there must be 4 probabilities corresponding to each. The sum of all those probabilities must equal to 1. With this information, we could already find the missing probability.
Summation of P = 1 = 0.40 + 0.20 + 0.20 + x
x = 1 - 0.4 - 0.2 - 0.2
x = 0.2 <-- missing probability
Answer:
c= 7/3
Step-by-step explanation:
To solve for c:
Simplify the equation by moving all numbers to one side and variables to the other
-9c-4=-25
-9c= -25+4
-9c=-21
Now isolate c by dividing both sides by its coefficient (-9)
c= -21/-9
Since the (-) cancel out, this simplifies to:
c= 21/9
Now reduce the fraction by dividing the right hand side by a common value of 3:
c= 7/3
