3 1/3(2 1/5x-4 2/3)-5 5/6=0
Since you can't subtract 2 1/5x and 4 2/3 together you would use the next step in the order of operations which is multiplication.
(3 1/3)(2 1/5x)=(10/3)(11/5x)=110/15x
(3 1/3)(4 2/3)=(10/3)(14/3)=140/9
7 5/15x - 15 5/9
Then you would subtract 7 5/15x - 15 5/9 with 5 5/6.
7 5/15x -15 5/9 - 5 5/6=
15 5/9=15 10/18
5 5/6=5 15/18
7 5/15x - 15 10/18 - 5 15/18=
7 5/15x - 21 7/18=0
Then you would try to solve for x by isolating it on one side.
7 5/15x=21 7/18
110/15x=385/18
x=(385/18)(15/110)
x=5775/1980
x= 2 1815/1980
x= 2 363/396
x= 2 121/132
x= 2 11/12
I hope you understood!!!!

Suppose that on the average, 7 students enrolled in a small liberal arts college have their automobiles stolen during the semest

strojnjashka [21]

Answer:0.9991

Step-by-step explanation:

The Poisson distribution probability formula is given by :-

$P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}$ , where \lambda is the mean of the distribution and x is the number of success

Given : $\lambda=7$

The probability that more than 1 student will have his automobile stolen during the current semester is given by :-

$P(x\geq1)=1-P(x=0)=1-(\dfrac{e^{-7}7^0}{0!})\\\\=1-e^{-7}=0.99908811\approx0.9991$

Hence, the probability that more than 1 student will have his automobile stolen during the current semester =0.9991

Answer:

102

Step-by-step explanation:

The total of ratio units is ...

6 + 3 + 8 = 17

The difference between the Charlie's ratio units and Adrian's ratio units is ...

8 - 6 = 2

That is, the total number of ratio units is 17/2 = 8.5 times that difference.

The actual difference is 12 sweets, so the total number of sweets is ...

8.5 × 12 = 102 . . . . total sweets
