Answer:
Step-by-step explanation:
There are 4 terms
Coefficient of y term = 1
Constant = 8
The term without variable is the constant term.
Answer:
42+30=72
7+5=12
72-12=60
Blank=60
Step-by-step explanation:
<em><u>Answer:</u></em>
<em><u>y = 5, 3; x = 171, 155</u></em>
<em><u>Step-by-step explanation:</u></em>
8y - 15 = y^2
y^2-8y+15=0
y^2-3y-5y+15=0
y(y-3)-5(y-3)=0
(y-5)(y-3)=0
y can be 5 or 3.
x = 180 - (8y - 15)
x = 180 - (8(3)-15)
x = 180 - 9
x = 171
OR
x = 180 - (8(5) - 15)
x = 180 - 25
x = 155
The answer to this is 25 hope it helps
Answer:
1/24
Step-by-step explanation:
To start, we can calculate the probability of each individual event:
<u>Getting the person right:</u>
1/2
<u>Getting the weapon right:</u>
1/3
<u>Getting the room right:</u>
1/4
Here, you're trying to find the probability of the intersection of the three events. This means we must multiply the probabilities of the independent events together.
1/2*1/3*1/4=1/24
or
0.0417
Note that we multiply the probabilities together when the previous event doesn't affect the probability of the next event. In general, questions that ask for the probability of a happening and b happening mean you multiply the probability of a and b (events that satisfy your demands are decreasing because you need BOTH events to occur).
On the other hand, questions that ask for the probability of a or b happening, meaning the events that satisfy your demands will increase (2 options versus 1), so you'd add the probabilities of a and b happening.
Hope that makes sense, let me know if you have any questions!
