Answer:

Step-by-step explanation:
Given
Peter hits
Mary hits
Required
The probability that Mary wins
From the question, we understand that Peter throws the first.
If Mary is to win, then Peter has to lose his throw
Using the complement rule, the probability that Peter misses is:

So, the probability that Mary wins is:

This gives:

None? Idk if that is the correct answer or not because I don’t feel like doing it
#3: 15
#4: 13.2
#5: 5.44 (curious as to how you guessed 7)
#6: 7
#7: 7.3
#8: 15
#9: You'd round 0.9 to 1 and 3.78 to 4. 4/1 = 4
#10: Round 2.5 to 3. 36/3 = 12
#11: If they want you to round 0.25 down to 0, then 7/0 is undefined.
#12: 9.5 rounds to 10 142.5 rounds to 143. 143/10 = 14.3
#14: 24.8 cm divided by 175 = approximately 0.1417 cm per year. Round that up to approximately 0.14 per year.
Answer:
1/9^15
Step-by-step explanation:
Answer:
y=474+2x
y=350+4x
Answer: x=62 y=598
Step-by-step explanation:
Place the two equations equal to each other.
350+4x=474+2x
Then Subtract 350 from 474 which gets you to 124.
4x=124+2x
Then subtract 2x from both sides.
Which make the equation look like this: 2x=124
Now divide 124 by 2.
so x=62.
Then you will need to plug in x in one of the equations to know what y is.
I plugged it into this one: y=474+2(62)
Now solve.
It should get you to the answer of 598.
So, overall x=62 while y=598.
