Answer:
a) True
b) True
c) False
d) True
Step-by-step explanation:
A discrete variable is the one where the values taken by it are possible to count (usually the values are natural numbers)
On the other side, a continuous variable is the one that has an uncountable number of values. (usually the values are real numbers)
Considering these definitions we get:
a)The batting average of Joe’s favorite player is a continuous variable: True, this average can take any number among the real numbers.
b) The number of hot dogs that Joe bought is a discrete variable: True, Joe can only buy 1, 2, 3, 4... hot dogs, this set is countable and therefore is a discrete variable.
c) The number of strikeouts in the game is a continuous variable: False, the strikeouts are natural numbers (1, 2, 3, 4...) and therefore are countable and they are a discrete variable.
d) The Quakes standings in the league is a discrete variable: True. The standing of a team in a league is a discrete variable since it can be 1st place, 2nd place... and therefore it's countable.
1) -10,-2
2) -13,-3
3) 2,2
4) -5,3
Ain't nobody got time fo dat (drawing number lines)
7 and 1/4=7+1/4
7 and 1/4-3 and 3/4=4 and 1/4-3/4 means
7+1/4-3-3/4=4+1/4-3/4 rearange
7-3+1/4-3/4=4+1/4-3/4
4-2/4=4-2/4
4-1/2=4-1/2
3 and 1/2=3 and 1/2

Answer:
= - 3![(6)^{n-1}](https://tex.z-dn.net/?f=%286%29%5E%7Bn-1%7D)
Step-by-step explanation:
Note the common ratio r between consecutive terms, that is
r = - 18 ÷ - 3 = - 108 ÷ - 18 = 6
This indicates the sequence is geometric with n th term ( explicit formula )
= a![(r)^{n-1}](https://tex.z-dn.net/?f=%28r%29%5E%7Bn-1%7D)
where a is the first term and r the common ratio
Here a = - 3 and r = 6, thus
= - 3![(6)^{n-1}](https://tex.z-dn.net/?f=%286%29%5E%7Bn-1%7D)
