Answer:
3n + 3
Step-by-step explanation:
Mia is correct
When n= 1 , 3n + 3 = 3*1 + 3 = 3 + 3 = 6
When n =2, 3n + 3 = 3*2 + 3 = 6 + 3 = 9
When n = 3 , 3n +3 = 3*3 + 3 = 9 + 3 = 12
When n = 4, 3n + 3 = 3*4 + 3 = 12 +3 = 15
The general form of the linear equation is:
y = mx + c where:
m is the slope and c is the y intercept
We are given that the slope is equal to -2
Therefore, the equation now becomes:
y = -2x + c
To get the value of the c, we will use the given point (0,0) to substitute in the equation and solve for c as follows:
y = -2x + c
0 = -2(0) + c
c = 0
Based on the above calculations, the equation of the line would be:
y = -2x

Answer: nahh I have a quiz 3
Step-by-step explanation:
Answer:
The probability that exactly 6 transactions will be made at an ATM in the next 20 minutes = 0.06306 = 0.0631 to 4d.p
Step-by-step explanation:
This is a Poisson distribution problem
The Poisson distribution formula is given as
P(X = x) = (e^-λ)(λˣ)/x!
where λ = mean = 10 transactions per 20 minutes
x = variable whose probability is required = 6 transactions in the next 20 minutes
P(X = 6) = (e⁻¹⁰)(10⁶)/6! = 0.06306
