Answer:
a. He started with $50 in the the account.
b. The account grow by $10 dollars each week
c see graph
Step-by-step explanation:
y = 50 + 10x
We can rewrite this as
y = 10x+50
This is in the form y = mx+b
where m = 10 which is the slope and b =50 which is the y intercept
The y intercept = 50 is the starting value or the value when x = 0
a. He started with $50 in the the account.
The slope is how much it grows by as x grows. As x increase by 1 , y will grow by the slope or 10, so the account will grow by 10 each week.
b. The account grow by $10 dollars each week
c see graph

Answer:
If n = 1000000, then
If n = 10400, then
If N = 102, then
Step-by-step explanation:
Since the coin is fair, then the probability that a filp is heads is 1/2. Given N tries, the amount of heads can be approximated with a Normal distribution with mean μ = N *1/2 = N/2 and standard deviation σ = √(N*1/2 * 1/2) = √N/ 2
The density function of that random variable is given by de following formula
If n = 1000000, then
If n = 10400, then
If N = 102, then
