Answer:
x = -3, y = -3.5. As an ordered pair it is (-3, -3.5).
Step-by-step explanation:
9x − 4y = −13
9x − 2y = -20
Subtract:-
-2y = 7
y = -3.5.
Substitute for y in the first equation:
9x - 4(-3.5) = -13
9x = -27
x = -3.
Answer:
Step-by-step explanation:
1. What is the theoretical probability that a coin toss results in two heads showing?
25%
2. What is the experimental probability that a coin toss results in two heads showing?
50%
3. What is the theoretical probability that a coin toss results in two tails showing
0.5%
4. What is the experimental probability that a coin toss results in two tails showing?
25%
5. What is the theoretical probability that a coin toss results in one head and one tail showing?
0.5
6. What is the experimental probability that a coin toss results in one head and one tail showing?
0.5
7. Compare the theoretical probabilities to your experimental probabilities. Why might there be a difference?
0.5
There you go. Remember you can figure these answers out by yourself if you really try. From now on ill be answering questions and trying to help other people. Please read from your lessons as they can help you a lot, Thank you.
Answer:
y = -3x - .25 or y = -3x + -.25
Step-by-step explanation:
y = slope (x) + y-intercept
-4 = -3(1.25)+b
-4 = -3 .75 + -.25
-4 = -4
multiples of 4: 4,8,12,16,20,24,28,32,36,40,44,48,52,56,60
12 24 36 and 48 are the only common factors
so 4 days
X-y=30
y=15
x-15=30
X=30+15
= 45
Hope this helps u !!
