There is only one answer, x=7
The straight lines are asking to find the modulus or the size of the complex number.
For a complex number z = x + iy, [z] = √(x^2 +y^2)
Where x = Real Number, y = Imaginary number.
For 3 +i, x = 3, y = 1 (Note y is what number that is attached to i)
[3 + i] = √(3^2 +1^2) = √10 = 3.162
Answer:
y=2/3x+6
Step-by-step explanation:
The compound interest is applied to the remaining balance in the account
each subsequent year.
- The amount that must be deposited is approximately <u>$620.07</u>
Reasons:
The given compound interest rate, r = 6.25% = 0.0625
The balance in the account after 2 years, A = $700
Required:
The required deposit, <em>P</em>, that gives the given account balance after 2 years.
Solution:
The following is the compound interest formula to use;
Where;
t = 2 years
We get;
Which gives;
- The amount that must be deposited to give $700 after 2 years is P ≈ <u>$620.07</u>

Answer:
0.184
Step-by-step explanation:
As the statistician consultant, I would have to calculate the chance of having 2 ambulances on the freeway at this hours and relay the message to the dispatcher.
Probability of having the need for 2 ambulances.
We will have a poisson distribution:
Lambda = 1
P(x=2) = e^-2*1/2!
= 2.71828^-1/2
= 0.368/2
= 0.184
I would tell the dispatch rider that the possibility that 2 ambulances would be required is 0.184.
Thank you
