Answer:D
Step-by-step explanation:
Probability of rolling a 5 on the first roll is 1/6 because there is only 1 number to roll out of 6. Then, roll a number larger than 4 is 5 and 6. That is 2 numbers. 2 numbers out of 6. Multiply those 2. 1/6 * 2/6=2/36. Simplified is 1/18
4+3x = (k+2)x + 8
4+2+3x = (k+2)x + 8 - 2
6+3x = (k+2)x + 6
then 3x = k+2
so k = 3X-2
Answer:
(x−4)²+(y)²=1
Step-by-step explanation:
If you translate this into English, you get something like this:
The y value lies between -1 and 1, if the x value is between 3 and 5, This could very well be a circle with the center point M and a radius of 1.
The x-coordinate of the middle lies between 5 and 3, which is 4
The y-coordinate of the middle lies between -1 and 1, which is 0.
So the middle is (4 , 0) and radius is 1
The circle equation (xa) 2 + (yb) 2 = r 2
The circle with center M( a b ) and radius r has as a comparison:
(x - a)² + (y - b)² = r²
with a = 4 and b = 0 and r = 1
(x − 4)² + (y - 0)² = 1²
(x−4)²+(y)²=1
