Answer:

let the larger and smaller number be x and y respectively

first condition

x + y = 49

second condition

3x = 2y+97

3x-2y =97

Multiplying first condition by two and adding both equations

2x + 2y = 98

3x -2y = 97

5x = 195

x = 195/5 = 39

putting the value of x in

x + y = 49

y = 49 -39 = 10

again

Suppose you pay $1.00 to roll a fair die with the understanding you will get $3.00 back rolling a 4 or a 2, and nothing otherwis

There are 2 chances out of 6 to win $3

Every 6 rolls you are expected to win $6

Every 3 rolls you are expected to win $3.

On average, even though it's impossible, every roll you would make $1.

a) The halfway number is $\frac{-4.5}{10}$ .

b) The ascending order is $\frac{-1}{2}$ , $\frac{-4.5}{10}$ and $\frac{-2}{5}$ .

Step-by-step explanation:

a)Halfway number is otherwise Middle number.

The halfway number of two numbers = $\frac{sum of two numbers}{2}$ .

The halfway for $\frac{-2}{5}$ and $\frac{-2}{5}$ = $\frac{\frac{-2}{5}+ (\frac{-1}{2})}{2}$ .

= $\frac{-2}{5}+ (\frac{-1}{2})$ .

= $\frac{-4-5}{10}$ .

= $\frac{-9}{10}$ .

∴Halfway = $\frac{\frac{-9}{10} }{2}$ .

= $\frac{-4.5}{10}$

The halfway for $\frac{-2}{5}$ and $\frac{-1}{2}$ = $\frac{-4.5}{10}$ .

b) The ascending order is $\frac{-1}{2}$ , $\frac{-4.5}{10}$ and $\frac{-2}{5}$ .
