Y = -4x + 2
3x + 2y = 6 (or in y-intercept form y=-3/2x + 3)
2x - y = 7 equals y = 2x -7 in y-intercept form. This means that the line has a positive slope and therefore goes upwards. This cannot be a potential equation because the line shown is clearly pointing downwards.
y=5 indicates that the line is a horizontal line that neither points upwards or downwards. This cannot be a potential equation because the line is pointing downwards.
The only possible equations left are y= -4x + 2 and 3x + 2y = 6, both of which graph a line pointing downwards because their slopes are negative. Hope this helps!
Answer:
1. The probability that the student will get exactly 6 correct answers is .
2. The probability that the student will get more than 6 correct answers is .
Step-by-step explanation:
From the given information it is clear that
The total number of equations (n) = 10
The probability of selecting the correct answer (p)=
The probability of selecting the incorrect answer (q)=
According to the binomial distribution, the probability of selecting r items from n items is
where, p is probability of success and q is the probability of failure.
The probability that the student will get exactly 6 correct answers is
Therefore the probability that the student will get exactly 6 correct answers is .
The probability that the student will get more than 6 correct answers is
Therefore the probability that the student will get more than 6 correct answers is .
Answer: C peridotite
Step-by-step explanation:
idk lol i just got it right on the quiz
Hey there,
100% = 38.4
1% = 38.4 / 100
= 0.384
32.5% = 0.384 x 32.5
= 12.48
Thus, 12.48 is 32.5% of 38.4
Hope this helps :))
