ility that you will make a net gain of $4. ​(If you​ win, the casino gives you $ 4and you get to keep your $ 4​bet, so the net gain is $4.)

Answer:

a) - $0.169

b) - $0.04242

Step-by-step explanation:

Data provided in the question:

Bet amount = $4

Probability of losing $4 = \frac{258}{495}

Probability of gaining $4 = \frac{237}{495}

a) The expected value

= Winning amount × winning probability - Losing amount × Losing probability

= $4 × \frac{237}{495} - $4 × \frac{258}{495}

= $4 × \frac{237-258}{495}

= - $0.169 (Negative sign means loss)

b) The amount lost for each dollar = \frac{\textup{Expected Value}}{\textup{Bet amount}}

= \frac{\textup{-0.169}}{\$\textup{4}}

= - $0.04242

To take an Uber, it costs $4.00 plus an additional $1.50 per mile traveled.
slava [35]
You traveled 11 miles because if you did use 28.00 and $1.50 then you take that answer and then add the $4.00 and $3.00 you will get $7 so you just subtract that for the other number and you get 11 miles because it is $1.50 per mile

Assuming a linear relationship between x and y, if the coefficient of correlation (r) equals -0.75, this means that:
Gelneren [198K]

Since we are given that the relationship between x and y is linear. Therefore this means that the given equation takes the form of:

y = m x + b

where,

b is the y intercept of the equation

m is the slope of the equation

 

However we should take note that the slope m is directly proportional to the coefficient of correlation. Since our coefficient of correlation is negative, this only means that the value of y is decreasing with increasing x, hence plot of y and x is descending with increasing x. Furthermore, this also tells that for every 1 unit increase of x, there is a 0.75 units decrease of y.

Aleksandr-060686 [28]

Answer:

(b) 27

Step-by-step explanation:

every day, kojo write 3 pages

number of days he has written his story= d days

therefore number of pages he has written= 3d

from the final sentence,

3d= 81

<h3>(a) the equation to describe the situation: </h3><h3>3d= 81</h3>

(b) number of days kojo has been writing his story

3d= 81

dividing through by d

3d/3= 81/3

d = 27

<h3>therefore number of days = 27</h3>
