The average winning per bet is the mean or the expected value of winning a bet.

The statistical term that represents $0.94 is (c) the expected value

From the question, we understand that the gambler has an average winning of $0.94, when he places a bet of $1

This means that:

The average winning on a bet of $1 is $0.94

Average, in statistics means the mean or expected value

Hence, the statistical term for $0.94 is (c) the expected value

You earn $21.00 per hour at your job. If you get a 9% raise at the end of each year, what will your hourly rate, h, be after 5 y

NikAS [45]

Plug in the info given and solve:

h = 21(1.09)^5
h = $32.31

Please help!!!!!!<br><br> y=[?]°

coldgirl [10]

Answer:

Since there are already 2 angles shown, which are 48 and 90 (indicated by the square in the bigger triangle, we can set up an equation.

48 + 90 + y = 180

138 + y = 180

-138 + 138 + y = 180 - 138

y = 42°

2,-10,50,-250,.. Geometric sequence

nikklg [1K]

This question is incomplete, here is the complete question

What is the recursive formula for this geometric sequence 2, -10, 50, -250, .... ?

The recursive formula for this geometric sequence is:

$a_{1}$ = 2; $a_{n}$ = (-5) • $a_{n-1}$

Step-by-step explanation:

To find the recursive formula for a geometric sequence:

Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
Find the common ratio. (The number you multiply or divide.)
Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.

The recursive formula is:

$a_{1}$ = first term; $a_{n}$ = r • $a_{n-1}$ , where

$a_{1}$ is the first term in the sequence
$a_{n-1}$ is the term before the nth term
r is the common ratio

∵ The geometric sequence is 2 , -10 , 50 , -250

∴ $a_{1}$ = 2

- To find r divide the 2nd term by the first term

∵ $r=\frac{a_{2}}{a_{1}}$

∴ $r=\frac{-10}{2}=-5$

- Substitute the values of $a_{1}$ and r in the formula above

∴ $a_{1}$ = 2; $a_{n}$ = (-5) • $a_{n-1}$

The recursive formula for this geometric sequence is:

$a_{1}$ = 2; $a_{n}$ = (-5) • $a_{n-1}$
