Answer:
---- Set Builder
(50, ∞) ---- Interval Notation
Step-by-step explanation:
Given
x > 50
Required
Write as a
- Set builder
- Interval notation
As Set Builder:
x > 50 means that x is an integer and x is greater than 50.
In set builder notation, integers are represented with z.
So, the above can be represented as:
This translates to:
x is a member of the set of integers such that x is greater than 50
As Interval Notation:
In interval notation, we make use of brackets to represent the intervals.
In this case > is represented by (a,b)
Where a and b are the intervals of the notation
Since x > 50, then a = 50 and b = ∞ because we only know the starting point and not the end point.
<em>Hence: x > 50 in interval notation is (50, ∞)</em>

Answer:
DA= $800 and DB= $1200
Step-by-step explanation:
Equation I (Interest of Bank A):
IA= 0.06/year*DA *1year (DA= Deposit in Bank A)
IA= 0.06*DA
Equation II (Interest of Bank B):
IB= 0.08/year*DB *1year (DB= Deposit in Bank B)
IB= 0.08*DB
Total interest:
TI=IA+IB=$144
Total deposit:
TD= DA +DB= $2000
Adding equations I and II:
IA+IB = 0.06DA +0.08DB
$144= 0.06DA+0.08DB
(DB= $2000-DA)
When replacing DB:
$144= 0.06DA + 0.08($2000-DA)
Applying distributive property:
$144= 0.06DA + (0.08*$2000) -0.08DA
$144= -0.02DA + $160
0.02DA= $160-$144
0.02DA = $16
DA= $16/0.02
DA= $800
DB= $2000-$800
DB= $1200
Answer:
B) 30min
Step-by-step explanation:
Start with 2 and continue to multiply that by 2 until you get 128
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
Then start with what you think could be the right answer based on how many intervals there are.
You know it can't be 15 because there definitely isn't enough and you know its not 1hr because theres way more than 3.
So you're left with either B) 30min or C) 45min
It has to be B) 30min because there are 6 intervals and 30min goes into an hour twice, meaning that if every 2 intervals is an hour there are 3 hours.
