Answer:

Step-by-step explanation:

(2 spreadsheets, 3 databases and 4 presentations,


As not mentioned other wise equal chances of all the outcomes is assumed so, by the classical definition of probability,
P(The chosen item is a odd numbered database)
=
This is a problem for 2 equations and 2 unknown.
so let x be the number of adults in the breakfast
y be the number of children present in the breakfast
so the total people attended is 500, in equation form
x + y = 500
and the total sales made by disney is $ 7355, in equation
17.95x + 12.95y = 7355
so we can solve the equation simultaneously so solve for the values of x and y
so the number of adults at the breakfast x = 176 adults and y = 324 children
First, you need to distribute the right side of the equation : 8n - 2
Now the equation is : 20 - 7n = 8n - 2
Add 2 to both sides : 22 - 7n = 8n
Add 7n to both sides : 22 = 15n
Divide both sides by 15 : ( I had to round this one) 1.5 = n
−5 < a − 4 < 2
+4 +4
-1 < a < 6
Answer is B. The second one
