Answer:

$Given:-$ Δ ABC

$AC~is~exteuded ~through ~C~to ~D$

$BC~is ~drawn ~to ~AC$

$Using ~Triangles~Exterior~angle~theorm,$

1) =∠3+∠4 and ∠4=∠5+∠6

∠7=∠3+∠2

So, only D) m∠7=m∠3+m∠2 is correct

rjkz [21]

Answer:

<h2>The standard error of the mean is 7.56</h2>

Step-by-step explanation:

The standard error of the mean is defined as the ratio of standard deviation to the square root of the sample size of a data. The standard error of the mean is mathematically expressed as shown below;

$X = \frac{\sigma}{\sqrt{n} }$

X is the standard error of the mean

$\sigma$ is the standard deviation

n is the sample size.

Given;

$\sigma = 121\\n = 256$

On substitution into the formula we have;

$X = \frac{121}{\sqrt{256} }$

$X = \frac{121}{16} }\\$

X ≈ 7.56

Consider the equation r = 5 sin(theta). Use the drop-down boxes to complete the sentences.

Answer:

circle
y-axis
5 units

Step-by-step explanation:

It can be helpful to actually see the graph. For 0 ≤ θ ≤ π, a circle is developed above the x-axis, symmetrical about the y-axis (θ=π/2). For π ≤ θ ≤ 2π, the same circle is traced again in the same direction (CCW), as values of r are negative for those angles.

The circle has a radius of 2.5, centered at (0, 2.5), so the diameter is 5 units. The length of the diameter is the farthest distance between any two points on a circle.
