Michael invested 5,000 in an account that has a 5.5% annual interest rate. What equation best describes investment after T years

ivolga24 [154]

Answer:

V = 5000 + 275*T for simple annual interest

or: A = 5000 * (1.055)^T for an annual compound interest

Step-by-step explanation:

I assume this is a simple interest rate. If not I will give the one for compound interest.

V = 5000 + 5000* 0.055 * T (Value of account after T years)

V = 5000 + 275*T for simple annual interest

or: A = 5000 * (1.055)^T for an annual compound interest

Th the mean of the data is set 15 what number is missing<br> 18,16_,9,12,23

Wittaler [7]

Answer:

The missing number on the given data set is 12.

Step-by-step explanation:

Here, the set of data = 18,16_,9,12,23

Let us assume the missing number in the data = m

The mean of the data = 15

Total number of observations = 6

Now, Sum of the data = 18 + 16 + m + 9+ 12+ 23 = 78 + m

Also, $\textrm{ Mean of the given Data} = \frac{\textrm{Sum of all observation in the data}}{\textrm{Total number of observations}}$

$\implies 15 = \frac{78+ m}{6} \\or, 15(6) = 78 + m\\\implies m = 90 -78 = 12$

or, m = 12

Hence, the missing number on the given data set is 12.
