Average national teachers salaries can be modeled using the equation y=9.25(1.06)^n , where y is the salary in thousands of doll

kiruha [24]

$y=9.25(1.06)^{n}$
Plug in $n$ to find $y$ .
$n$ would be $50$ because $2020-1970=50$ .

Use order of operations to solve.
$y=9.25(1.06)^{50} \\ y=9.25(18.42) \\ y=170.39$

Since $y$ is the salary in thousands, multiply $170.39$ by $1000$ .
$170.39*1000=17039$

A teacher can expect to have about $17,039 as a salary in the year 2020.

A single die is rolled twice. Find the probability of rolling an

Nady [450]

Answer: 1/6

Step-by-step explanation:

A die has 6 numbers which are 1, 2, 3, 4, 5 and 6.

Odd numbers in a die = 1, 3 and 6

Numbers greater than 4 = 5 and 6

Probability of rolling an odd number = 3/6 = 1/2

Probability of rolling a number greater than 4 = 2/6 = 1/3

We then multiply both values gotten. This will be:
