Answer:0.9991
Step-by-step explanation:
The Poisson distribution probability formula is given by :-
, where \lambda is the mean of the distribution and x is the number of success
Given : 
The probability that more than 1 student will have his automobile stolen during the current semester is given by :-
Hence, the probability that more than 1 student will have his automobile stolen during the current semester =0.9991
3/8+5/16
=3/8+5/16
=6/16+5/16
=6+5/16
=11/16
(Decimal: 0.6875)
The exponent of a number says how many times to use the number in a multiplication.
For Example, In 8² , the 2 is the number of times 8 has to be multiplied. In this case It has to multiplied by itself 2 times, 8x8 = 64 so 8² = 64.
Another example is 9³ since the number above is 3 we have to multiply 9 three times, 9x9x9 = 729 which means 9³ = 729.
Hope this helps
So, how much acid is there in 6 gallons? well is 20% acid or (20/100), so the amount of acid in it just (20/100) * 6 or 1.2, the rest is say water.
now, if we want a 90% solution, and say we add "y" gallons, how much acid is in it? well (90/100) * y, or 0.9y.
now let's add "x" gallons of pure acid, now, pure acid is just pure acid, so is 100% acid, how much acid is there in it? (100/100) * x, or 1x or just x.
we know whatever "x" and "y" amounts are, they -> x + 6 = y
and we also know that x + 1.2 = 0.9y
Answer:
They practiced a total of 75 math facts in all!
60 + 15 = 75 :D
