Answer:
$512
Step-by-step explanation:
His bank account started at a balance of $124.
He wrote a check, which decreased his balance by $147. His new balance is:
124 - 147 = -$23
Jeremy was then charged an overdraft fee, decreasing his balance by $32. That is:
-23 - 32 = -$55
He deposited a paycheck, which increased his balance by $567. His account balance will become:
-55 + 567 = $512
His account balance after those transactions is $512.

five degrees:)
Step-by-step explanation:
2 hours= -10
1 hour= half of ten
so you could say -5 or that it drops by five degrees every hour.
hope this helps!
Answer:
C.) Number of successful trials / Total number of trials
Step-by-step explanation:
The empirical probability of an event 'E' is defined as :
(Number of successful occurrences of event 'E' / Total number of trials)
The empirical probability requires that an experiment of a chosen number of trials be performed. The ratio of the number of success to the total number of trials is used to estimate the empirical probability of such event.
P(Empirical) = (Number of successful trials / Total number of trials)
This is different from the use of sample space in the evaluation of theoretical probability whereby all possible occurences is used to estimate the probable outcome of an event.
P(theoretical) = (number of required outcomes / total number of possible outcomes)
X^2 + 4x -21
= (x +7)(x - 3)
hope that helps
