Answer:
the answer is 2
Step-by-step explanation:
Let the age of Jay be x years, so age of Jay's father is 2x years .
After 20 years,
Jay's age will be
And Jay's father age will be
But at that time, jay's age will be
So we have
Cross multiplication
Therefore Jay's age is 20 years and Jay's Father's age is 40 years .
7 socks were sold
7*8=56
11-7=4
4×11=44
56+44=100
This proves the answer of 7 to be correct
The inequality 2.50x>40.00 represents the number of lunches needed to be purchased for the monthly lunch pass to be a better deal.
Given that:
Cost of each lunch = $2.50
Cost of monthly lunch pass = $40.00
Number of lunches = x
For making the monthly pass a better deal, the cost of lunches should be greater than the cost of monthly lunches, therefore
Cost of lunch * Number of lunches > Cost of monthly lunch pass
2.50x > 40.00
Hence,
The third one....
it fulfill all required characteristics of lines given.
If P(A) times P(B) is equal to P(A n B), then that shows the events are independent. Otherwise, they are dependent. When I write "A n B", I mean "A intersect B". The intersect symbol looks similar to the lowercase letter n.
P(A)*P(B) = (3/4)*(2/5) = (3*2)/(4*5) = 6/20 = 3/10
Since that result is not the same as P(A n B) = 1/3, this means that the events are not independent. They are dependent events. The answer is choice D
