Answer: D, .1
Step-by-step explanation: 10 marbles and 1 green
50 times she pulled and almost every ten tries she got green meaning there's a high chance of her getting 1 green every 10 tries
Answer:
The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable. In other words, the dependent variable is the one you measure and the independent is the one you change in an experiment.

Answer:
Step-by-step explanation:
If the impedance is related to the voltage and the current by the formula V = IZ where;
V is the voltage
I is the current
Z is the impedance
Given
I = 0.4+3i
V = 0.3-2i
Voltage V = (0.4+3i)(0.3-2i)
V = 0.4(0.3)-0.8i+0.9i-6i²
V = 0.12+0.1i -6i²
Since i² = -1
V = 0.12+0.1i-6(-1)
V = 0.12+0.1i+6
V = 6.12+0.1i.
Hence the impedance is 6.12+0.1i
For a line with equation y= m x + b
the y intercept is
x = 0, y = b
(0, b )
The secant of the angle through a point (-5, 3) is -13/5
<h3>Equation of a circle</h3>
The equation of a circle with center (0,0) is given by
x² + y² = r² where r = radius of circle
Now, comparing this to the equation of the given circle x² + y² = 169,
⇒ r² = 169
r = √169
r = 13
<h3>Secant of angle </h3>
The secant of the angle through a point (x, y) is secФ = r/x where
- r = radius of circle and
- x = x-coordinate of point
Now for the point A(-5,12), x = -5.
Since r = 13
secФ = r/x
= 13/-5
= -13/5
So, The secant of the angle through a point (-5, 3) is -13/5
