Answer:
Result is significant ; hence we can conclude that the average age of male is greater than that of females.
Step-by-step explanation:
Given that:
Let :
u1 = mean age of male
u2 = mean age of female
Null hypothesis : H0 : u1 = u2
Alternative hypothesis : H1 : u1 > u2
P value for hypothesis test conducted = 0.0095
Using a significant level α 0.05 or 0.01, :
The P value < α
Since, the P-value is less than α, then the result is significant and we thus we can reject the Null and conclude that the average age of males is greater Than that of females that play on the golf course.
Answer: D
The relation represents _y_ as a function of x, because each value of _x_ is associated with a single value of _y_.

Answer:
2400 coins
Step-by-step explanation:
What we should do is calculate the Least Common Multiple of 80 and 75, since each of us put together a group with this amount of coins, this way we will know the amount of coins when they are equal.
To obtain the L.C.M
you have to factor both numbers and multiply the numbers whose exponent is the highest, it looks like this:
75 = 5 ^ 3
80 = 2 ^ 4 * 5
We multiply those with the highest exponent,
5 ^ 3 = 75
2 ^ 4 = 16
75 * 16 = 1200.
L.C.M. is 1200.
Since they tell us that they have less than 2000 coins, this is the correct answer, because when assembling these groups in this way, they coincide again in 2400, which is over the limit.
So, each one has 1200 coins, in total it would be:
1200 * 2 = 2400
Between them they have a total of 2400 coins
