Hello there!
How do you find the y-intercept?
Answer: To find the y-intercept, substitute in 0 for x and solve for y
y = x² + 3x + 5
y = (0)² + 3(0) + 5
y = 0 + 0 + 5
y = 5
Thus, the correct answer is option D (0,5)
I really hope this answer is clear enough for you to understand. If you have questions about the answer, please let me know.
As always, I'm glad to be your helper this evening~!
Answer:
not sure tbh
Step-by-step explanation:
Answer:
funny I have this question and I thought it was D
It is 44. Can't argue about that
<span>Probability = 0.063
Fourth try = 0.0973
Let X be the number of failed attempts at passing the test before the student passes. This
is a negative binomial or geometric variable with x â {0, 1, 2, 3, . . .}, p = P(success) = 0.7
and the number of successes to to observe r = 1. Thus the pmf is nb(x; 1, p) = (1 â’ p)
xp.
The probability P that the student passes on the third try means that there were x = 2
failed attempts or P = nb(2, ; 1, .7) = (.3)2
(.7) = 0.063 . The probability that the student
passes before the third try is that there were two or fewer failed attmpts, so P = P(X ≤
2) = nb(0, ; 1, .7) + nb(1, ; 1, .7) + nb(2, ; 1, .7) = (.3)0
(.7) + (.3)1
(.7) + (.3)2
(.7) = 0.973 .</span>
