Help please !!! At a local Brownsville play production, 420 tickets were sold. The ticket prices varied on the seating

Radda [10]

Answer:

n = 12$ x = 8$ y = 10$ where n, x, and y are number of tickets

12 n + 8 x + 10 y = 3920 and n + x + y = 420

12n + 8 (x + y) + 2 y = 3920

12 n + 8 (5 n) + 2 y = 3920 since 5 (x + y) = n

52 n + 2 y = 3920 or y = 1960 - 26 n

Also, n + x + y = 420 or n + 5 n = 420 since x + y = 5 n

n = 70 so 70 of the $12 were sold

And since y = 1960 - 26 n we have y = 140 tickets

Now 12 * 70 + 8 x + 140 * 10 = 3920

This gives x = 210 tickets

Check: 210 + 140 + 70 = 420 tickets

Also, 12 * 70 + 210 * 8 + 140 * 10 = 3920

Answer:

Step-by-step explanation:

a) If events A and B are independent we have

P(A/B) =P(A)

But here P(A/B) = 0.8 and P(A)=0.2

Hence A and B are not independent.

b) If events A and B are independent we have

P(A/B) =P(A)

But here P(A/B) = 0.6 and P(A)=0.3

Hence A and B are not independent.

c) If events A and B are independent we have

P(A/B) =P(A)

Jere P(A/B) = 0.5 and P(A)=0.5

Hence A and B are independent.

Answer:

19.63

Step-by-step explanation:

If the radius is 5 centimeters, then the area is just 3.14*5^2 / 4, which is 78.5/4. This is equal to 19.625. Rounding this give us 19.63 as the final answer

In the xy coordinate plane the slope of line p is 1 2 and its x-intercept is -3. Find the equation of a line that is perpendicul

Novosadov [1.4K]

Answer:

Option C) y = -2x - 6

Step-by-step explanation:

The correct question is

In the xy coordinate plane the slope of line p is 1/2 and its x-intercept is -3. Find the equation of a line that is perpendicular to p and intersects p at is x-intercept.

step 1

Find the slope of a line that is perpendicular to p

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)

$m_1*m_2=-1$
