The choose ( 0.25 )
Relative Frequency = Category Frequency / Total Frequencies
Category Frequency (prefer tennis) = 7
Total Frequencies = 28
Relative Frequency = 7 / 28
Relative Frequency = 0.25
I hope I helped you^_^
Answer:
m= 72/37
Step-by-step explanation:
36 x 2 - m = 6^2m
Multiply the numbers:
72 - m = 6^2m - 72
Subtract 72 from both sides:
-m - 36m = 36m - 72 - 36m
Simplify:
37m= -72
Divide both sides by 37:
-37m/-37 = -72/-37
Simplify:
72/37
So the circle is really easy to graph. All you have to do is put a point at (1,2). Then another four points: 8 to the right of the center, 8 up from center, 8 left from center, and 8 down from center. Then contect the outer points.
The parabola is a little harder. So I can't see the equation very well, but I'm going to assume your vertix is correct. So put a point at (0,0).
The focus is 4 up from the center (0,4). The directrix is the same distance from the vertix as the focus, in the opposite direction. But it'll be horizontal or vertical line. This one I, believe, is y=-4.
So the parabola will open away from the directrix and towards the focus. You need two more points to graph this.
If I remember correctly, the other two points should be 2 x the focus/directrix distance. So 8, but even with the focus. Your other two points would be (0,12) (0, -4)
Then just connect the vertix to these two points. The only thing I need to double check is the distance betwen the focus with the two points.
Option 1: At x = 0,
f(x) = 128(0.5)^0 = 128(1) = 128 (not satisfy the ordered pair which is (0,128))
Option 2: At x = 1,
f(x) = 128(0.5)^1 = 128(0.5) = 256 (not satisfy the ordered pair which is (1,256))
Option 3: At x = 3,
f(x) = 128(0.5)^3 = 128(1/2)^3 = 128(1/8) = 16 (satisfy)
Hence, the answer is Option 3.
Answer:
6
Step-by-step explanation:
3(x+2) = 4x
3x + 6 = 4x <- you times the x and 2 that is inside of the parentheses by the 3 that is on the outside
3x - 3x + 6 = 4x - 3x <- you have to subtract the 3x from the left side and you have to do the same on the right so you can get the numbers alone.
6 = x
