1.If y varies directly with x
Introduce the constant term k
2.y=kx
where k is the constant term
substitute the value of x and y to form the law
-1=3k
k=-1\3
:y=-1\3x....is the law
To find the value of y when x is 9
Reinstate the law which is y=-1\3x and substitute the value of x to find y
y=-1\3*9
y=-3
199 is greater than 190, and less than 200.
Rolling a die has a 1/6 chance for each side.
If a 6 is rolled 4 times in 24 rolls, this is what the probability should be, so the answer is A. 16.7%
The answer will be x=-3 y=-4
No because the 2 in 3.28 isnt higher than 5 and the 1 in 4.1 isnt higher than 5 it has to be high than 5 to be rouned up
