The experimental probability would be the number of A’s you have out of the number of quizzes you took:
Experimental probability would be 6/18 which reduces to 1/3
The answer is 1/3
Answer:
stop telling people to do your homework on canvas!
Step-by-step explanation:
f(x) = 2x + 1
To find the inverse, f^-1(x), of the function:
Put the function as an equation:
y = 2x + 1
Then move x to the left and y to the right;
x = 2y + 1
Then solve for y;
y = x/2 - 1/2
f^-1(x) = y
f^-1(x) = x/2 - 1/2
Answer:
x= 3.47 or x= -4.47 , y= 0.53 or y= 8.47
Step-by-step explanation:
quadratic equation:
x^2 + y^2 = 16
(-b± √b^2 - 4*a*c) /2
(-1 ± √ 1-4*1*16)/2
(-1 ± 3√7)/2
(-1 ± 7.94)/2
(-1 + 7.94 )/2 or (-1-7.94)/2
x= 3.47 or -4.47
therefore:
x+y = 4
3.47 + y = 4 or -4.47 + y = 4
y = 4-3.47 or y = 4+ 4.47
y= 0.53 or y = 8.47
