Answer:
x=-2, y=3. (-2, 3).
Step-by-step explanation:
x-4y=-14
x+5y=13
--------------
-x+4y=14
x+5y=13
----------------
9y=27
y=27/9
y=3
x+5(3)=13
x+15=13
x=13-15
x=-2

Answer:
Jim's error is " He did not multiply Three-fifths by 2 before applying the power "
Step-by-step explanation:
Jim's evaluating expression is
To verify Jim's error :
Jim's steps are
Therefore
Jim's error is " He did not multiply Three-fifths by 2 before applying the power "
That is the corrected steps are
( using the property )
The number is irrational, which means those y values in the table are irrational as well. So there's no way to get exact fractions for any of the decimal values.
The next best thing is to get approximate fractions.
A number like 4.1548 is the same as
Then we can say:
Optionally we can reduce that if you wanted.
So the fraction 41548/10000 turns into the decimal 4.1548
The other decimal values are handled in a similar fashion.
I'm not sure why your teacher wants you to work with fractions. It's better if somehow you can type in the coordinate values as they appear in decimal form.
Answer:
0.4
Step-by-step explanation:
Let X be the random variable that represents the number of consecutive days in which the parking lot is occupied before it is unoccupied. Then the variable X is a geometric random variable with probability of success p = 2/3, with probability function f (x) = [(2/3)^x] (1/3)
Then the probability of finding him unoccupied after the nine days he has been found unoccupied is:
P (X> = 10 | X> = 9) = P (X> = 10) / P (X> = 9). For a geometric aeatory variable:
P (X> = 10) = 1 - P (X <10) = 0.00002
P (X> = 9) = 1 - P (X <9) = 0.00005
Thus, P (X> = 10 | X> = 9) = P (X> = 10) / P (X> = 9) = 0.00002 / 0.00005 = 0.4.
