Gizmo is investing in TikTok stock. He plans on adding an additional $250 at the end of every year and the expected monthly rate of return is 8.3% of the amount invested, calculated at the end of the month. If he starts with $425 in the account, write an equation that models the amount of money in the account each month for the first year.

15/2

Step-by-step explanation:

The equation would be 425 x .83(12) + 250 because 425 is what he has at first, then times .83 which is what returns back to him each month, which .83 is multiplied by 12 which is how many months that are in a year plus 250 which is what he adds on after each year

ANSWER:

We have to write an equation of that models the amount of money in the account each month for the first year.

We need the Exponential Equation Formula:–

Y is the amount of money in the account.

a is the initial amount he starts with

b is the amount being added each month

x is the rate of return

So, y = 425 * 2501.083

- 70

this is the answer for you hope it

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
