Answer:
-7 1/6
Step-by-step explanation:
Subtract the whole numbers first.
-5-2 = -7
Now the fractions:
1/2 and 1/3
We need to find a common denominator. It's 6.
So,
for 1/2 multiply the numerator and denominator both by 3. You get 3/6.
Now 1/3:
Multiply 1 and 3 with 2. you get 2/6.
Subtract:
3/6-2/6=
1/6
Putting whole number and fraction togethr: -7 1/6
Answer:
Yes
Step-by-step explanation:
If you use the Pythagorean theorem you will see that it is indeed a right triangle.
This is fairly complex, but looks like fun.
So first lets count how many bids are made till the bidding goes up to 160.
That is 100*160=16000
How much will be your random bid. Each bid has equal chance so it is the avarge of all bids. (1cent + 160dollars)/2 = 80dollars (rounded)
What is your chance of winning: 1 bid wins out of 16000 so 1/16000.
When you win your profit is 2000-80dollars=1920
1920/16000= 0.12 dollars
You entering the bidding costs 1 dollar and your average win is 0.12
This the outcome is 0.12-1=-0.88 dollars

Answer:
Correct answer: Third answer aₙ = -5 · 2⁽ⁿ ⁻ ¹⁾
Step-by-step explanation:
Given:
-5, -10, -20, -40,.....
First term a₁ = -5
Second term a₂ = -10
Third term a₃ = -20
Common ratio or quotient
q = a₂ / a₁ = a₃ / a₂ = -10 / -5 = -20 / -10 = 2
q = 2
First term a₁
Second term a₂ = a₁ · q = a₂ · q²
Third term a₃ = a₂ · q = a₁ · q³
.....................................................
n-th term aₙ = a₁ · q⁽ⁿ ⁻ ¹⁾
aₙ = -5 · 2⁽ⁿ ⁻ ¹⁾
God is with you!!!
