The ratio 9:7 gives you following statement:
-  Carl will win in 9 cases from 9+7=16;
 -  Carl will lose in 7 cases from 16.
 
Then the probability that Carl will lose is

Answer:
2.47 
Step-by-step explanation:
convert it to a decimal = 2.47058823.... 
then round that to a nearest hundredth = 2.47

Answer: Statement p is false.
Step-by-step explanation:
In both cases, we need to isolate the variables:
p: -3*x + 8*x - 5*x = x
    (-3*x - 5*x) + 8*x = x
     -8x + 8*x = x
         0 = x
This will be true only for one value of x, so this is not always true, which means that the statement is false.
q: (3*x)*(5*y) = 15*x*y
let's solve the left side:
   3*x*5*y = 15*x*y
   (3*5)*(x*y) = 15*x*y
    15*x*y = 15*x*y
This is true for every value of x and y, then this statement is true.
 
        
             
        
        
        
Answer:
x = 2
Step-by-step explanation:
y = - 5 is a horizontal line parallel to the x- axis.
A line perpendicular to it will be a vertical line parallel to the y- axis with equation
x = c
Where c is the value of the x- coordinates the line passes through.
The line passes through (2, 7) with an x- coordinate of 2, thus
x = 2 ← is the equation of the perpendicular line
