Answer: The equation that represents the other equation is 
.
The solution of the system is <u>(3,6).</u>
Step-by-step explanation:
Linear equation: 
, where m= slope
c = y-intercept.
In the first table, the y-intercept = 5 [ y-intercept = value of y at x=0.
Slope for first table = 
The equation that represents the first table:
So, the equation that represents the other equation is .
Also, the solution of the system is the common point (x,y) that satisfy both equations in the system.
Here, x=3 and y=6 is the common value in both tables.
So, the solution of the system is <u>(3,6).</u>
Answer:
πr²
Step-by-step explanation:
(pi times radius of circle)²
Answer:
1) A
2) x = 60
Step-by-step explanation:
1) A cuz complementary these two angles add up to be 90 degrees
2) 2x - 30 = 90
2x = 120
x = 60
Answer:
Probability = 0.12025
Step-by-step explanation:
P (Am) = 1/50 = 0.02 {Magazine ad}
P (At) = 1/8 = 0.125 {Television ad}
P (Am ∩ At ) = 1/100 = 0.01 {Both ads}
P (Am U At) = P (Am) + P (At) - P (Am ∩ At )
= 0.02 + 0.125 - 0.01
P (Am U At) = 0.135 {Person sees either ad}
P (Am' ∩ At') = 1 - P (Am U At)
P (Am' ∩ At') = 1 - 0.135 = 0.865 {Person sees none ad}
Prob (Purchase) = Prob (Purchase with ad) + Prob (purchase without ad)
P (P/ A) = 1/4 = 0.25 , P (P / A') = 1/10 = 0.1
P (P) = (0.25) (0.135) + (0.1) (0.865)
= 0.03375 + 0.0865
0.12025
