Answer:

1/12

Step-by-step explanation:

Total number is 20.

Distribution is:

Art + Biology = 1
Biology = 1
Neither = 7

The rest = 20 - 9 = 11, the Art students

Total number of Art students becomes 12

The probability would be then:

1/12

An isosceles triangle has its vertex at the origin and its base parallel to the x-axis with the vertices above the axis on the c

Virty [35]

We are given with an isosceles triangle having a vertex on the curve given y =27-x^2 .
The area of the triangle, A= xy = x (27-x^2)
A' = 27-x^2-2x^2 = 0
x = 3
Amax = 3(27-9) = 54 units2

Solve the equation by completing the square 5x(x+6)=-50

motikmotik

First lets distribute the 5x
5x^2 + 30x = -50

Lets divide every term by 5
x^2 + 6x = -10

To complete the square we have to half the b value, which in this case is 6. Then square it.
Half of 6 is 3, 3 squared is 9

Add that to both sides of the equation
x^2 + 6x + 9 = -1

Find the binomial squared
(x+3)^2 (If you're wondering how i got that please comment)

(x+3)^2 = -1

Take the square root of the equation of both sides
(x+3) = +/- i
x = -3 +/- i
x = -3 - i
and
x = -3 + i

Brian’s school locker has a three-digit combination lock that can be set using the numbers 5 to 9 (including 5 and 9), without r

andreev551 [17]

The possible digits are: 5, 6, 7, 8 and 9. Let's mark the case when the locker code begins with a prime number as A and the case when the locker code is an odd number as B. We have 5 different digits in total, 2 of which are prime (5 and 7).

First propability:
 $P_A=\frac{2}{5}=40\%$

By knowing that digits don't repeat we can say that code is an odd number in case it ends with 5, 7 or 9 (three of five digits).

Second probability:
 $P_B=\frac{3}{5}=60\%$
