Answer:
she watched 5/12 at night
Step-by-step explanation:
2/3 of the movie watched in total - 1/4 of the movie watched in the morning = amount of movie watched at night
X is a variable, while parenthesis suggest multiplication. Y equals the amount of her book left.
(1/5) + 3(1/5) + x = 1
(1/5) + (3/5) + y = 1
Combine like terms
(4/5) + x =1
Subtract four-fifths
x = (1/5)
Lydia has 1/5 of her book left to read.
Using the given exponential function, we have that:
Every minute, the number of bacteria decays by a factor of 0.98.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:
In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
In this problem, the function is, for the amounts each second:
The initial amount is of 6000 bacteria. After 60 seconds = 1 minute, the amount will be of:
The decay factor after 1 minute is:
(6000 - 125)/6000 = 98% = 0.98.

Answer:
Anytime the correlation coefficient, denoted as r, is greater than zero, it's a positive relationship. Conversely, anytime the value is less than zero, it's a negative relationship. A value of zero indicates that there is no relationship between the two variables
