I don't understand. What are the values given? Are they values of an x,y plot?
If you plot them they are a straight line with y =6x - 2.9 but I don't know what you mean by when x=3 and y = 4?
Using addition
x-y+1/2x+y=1+5
x+1/2x+0y=6
3/2x=6

3x=12
x=4
Using the value of x
x-y=1
4-y=1
y=3
With x as 4 and y as 3, their product is 12
And can be written as (4,3)
1890.56 / 4 = 472.64 / pi = 150.4459846
square root of 150.4459846 = 12.26564245 = radius
12.26564245 x 2= 24.53128489
the answer is number 2
Answer:
Step-by-step explanation:
In general, probably can be found as n(E)/n(S), where n(E) is the number of favorable outcomes, and n(S) is the number of total outcomes.
n(S) is the number of ways any 9 students can by picked from the audience, which is 9/140.
n(E) is the probability of picking four students from our school and five students from another school. This is (4/30)*(5/110) = 9/3300 =3/1100
n(E)/n(S) = (3/1100) / (9/140) = (3/1100) * (140/9) = 14/330
