write an equation for the graph of the line that passes through the point (3,2) and is perpendicular to the line x-2y=-6
spin [16.1K]

Answer:

The equation of the line would be y = -2x + 8

Step-by-step explanation:

In order to find this, we first need to find the slope of the original equation. We can do this by solving for y.

x - 2y = -6

-2y = -x - 6

y = 1/2x + 3

Now that we have a slope of 1/2, we know the new perpendicular line will have a slope of -2. We know this because perpendicular lines have opposite and reciprocal slopes. This means we flip it and change the sign. Now we can use this slope along with the point to find the equation.

y - y1 = m(x - x1)

y - 2 = -2(x - 3)

y - 2 = -2x + 6

y = -2x + 8

g The probability 0.15. The probability that is 0.085. What is the probability that a undergraduate is a Junior and a Nursing ma
Crazy boy [7]

<em>Question:</em>

<em>The probability that a UCR undergraduate majors in Nursing is 0.15. The  probability that a UCR undergraduate is a Junior is 0.20. The probability that a UCR  undergraduate is a Junior or a Nursing major is 0.085. What is the probability that a UCR  undergraduate is a Junior and a Nursing major?</em>

Answer:

P(J\ and\ N) = 0.265

Step-by-step explanation:

Given

Represent Junior with J and Nursing Major with N.

So, we have:

P(N) = 0.15

P(J) = 0.20

P(J\ or\ N) = 0.085

Required

Determine P(J\ and\ N)

In probability, for events A and B

P(A\ and\ B) = P(A) + P(B) - P(A\ or\ B)

In this case:

P(J\ and\ N) = P(J) + P(N) - P(J\ or\ N)

Substitute values for P(J), P(N) and P(J or N)

P(J\ and\ N) = 0.20 + 0.15 - 0.085

P(J\ and\ N) = 0.265

<em>Hence, the probability that an undergraduate is a Junior and major in Nursing is 0.265</em>
