The balance in my bank account went down $85 in 15 days. How much did it change per day. Use a positive number to represent a gain of money and a negative number to represent a loss of money.
The change in balance is a loss of money, so the change is -85.
The change of -85 occurred in 15 days, so the average change per day is
-85/15

Answer:
<h2>R
(19, 4)</h2>
Step-by-step explanation:
Given the midpoint 
to be (19.5, 9.5) with one ens point S as (20, 15), to get the coordinate of the other end point, we need to use the formula for calculating the midpoint of two coordinates.
for x coordinate;
X = 
for y coordinate;
Y = 
where (X, Y) is the midpoint
Given 
= 20, and 
= 15, we are to get the coordinate (
, 
)
(X, Y) = ![[\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%2C%20%5Cfrac%7By_1%2By_2%7D%7B2%7D%5D)
(19.5, 9.5) = ![[\frac{20+x_2}{2}, \frac{15+y_2}{2}]](https://tex.z-dn.net/?f=%5B%5Cfrac%7B20%2Bx_2%7D%7B2%7D%2C%20%5Cfrac%7B15%2By_2%7D%7B2%7D%5D)
comparing the coordinates;
The coordinate R will be (19, 4)
Answer:
Option 2
Step-by-step explanation:
Checking whether P(A) × P(B) = P(A∩B) :
Since this does not obey the Multiplication rule of probability, these events are not independent.
So, the answer is :
<u>No, they are dependent because P(A) ⋅ P(B) ≠ P(A ∩ B)</u>
