1000x2 = 2000
1000/2 = 500
2000 initial investment
2500 total after all is said and done
equals a $500 total return on the two investments
Answer:
= -
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
here a = 14 and r = = - , hence
= 14 × = 14 × - = -
Answer:
The probability that any 7 randomly chosen parking spots have 2 SUVs and 5 trucks or 3 SUVs and 4 trucks is 49/60
The probability that of any 7 randomly chosen vehicles, exactly 1 is an SUV is = 7/40
Step-by-step explanation:
probability of taking 7 vehicles from 10 vehicles = 10C₇
number of ways taking 2 SUVs and 5 trucks = 3C₂* 7C₅ = 63
number of ways taking 3 SUVs and 4 trucks =3C₁*7C₄ = 35
number of ways taking 2 SUVs and 5 trucks or 3 SUVs and 4 trucks = 63 + 35 = 98
The probability that any 7 randomly chosen parking spots have 2 SUVs and 5 trucks or 3 SUVs and 4 trucks is = 98/120 = 49/60
number of ways taking 7 randomly chosen vehicles, exactly 1 is an SUV = 3C₁*7C₆ = 21
The probability that of any 7 randomly chosen vehicles, exactly 1 is an SUV is 21/120 = 7/40
Answer:
572
Step-by-step explanation:
3(4)*(7)^2-4^2
Answer:
Step-by-step explanation:
20y - 60 = 5x
add 60 to both sides:
20y = 5x + 60
divide through by 20:
y = (1/4)x + 3
slope = 1/4
y-intercept = (0, 3)
