Statistics show on average an adult person receives 425 pieces of mail each year with a standard deviation of 50. What are the m

Kisachek [45]

Answer:

The answer is 60.11

Step-by-step explanation:

An adult person receives 425 pieces of mail each year with a standard deviation of 50.

Now, we have the following details :

Mean of sample = 425

sigma = 50

Standard error = $\frac{425}{\sqrt{50} }$

= $\frac{425}{7.07}$ = 60.11

Answer:

(7.5 , 5.5)

Step-by-step explanation:

The midpoint is halfway between the two end points:

Its x value is halfway between the two x values

Its y value is halfway between the two y values

To calculate it:

Add both "x" coordinates, divide by 2

Add both "y" coordinates, divide by 2

The diagram below shows an Isosceles triangle. Label the base angles and the vertex

Dmitry [639]

The base angles of an isosceles triangle are equal

The base angles are 15 degrees, while the vertex angle is 150 degrees

The base angles are given as:

Base = (6a- 3) and (a + 12)

So, we have:

$\mathbf{6a -3 =a + 12}$

Collect like terms

$\mathbf{6a -a =3 + 12}$

$\mathbf{5a = 15}$

Divide both sides by 5

$\mathbf{a = 3}$

Substitute 3 for a in Base = (6a- 3),

$\mathbf{Base = 6 \times 3 - 3}$

$\mathbf{Base = 18 - 3}\\$

$\mathbf{Base = 15}$

So, the base angle is 15 degrees.

The vertex angle is calculated using:

$\mathbf{Vertex=180 -2 \times Base}$

So, we have:

$\mathbf{Vertex=180 -2 \times 15}$

$\mathbf{Vertex=150 }$

Hence, the vertex angle is 150 degrees

Trigonometry that’s due in one hour :(

expeople1 [14]

Answer:

(a) $\theta=\tan^{-1}(-0.890)$

$\implies \theta=-41.66908262 \pm 180 \textdegree n$

$\implies \theta=138.3309174..., 318.3309174...$

$\implies \theta=138\textdegree, 318\textdegree$

(b) $\theta=\cos^{-1}\left(\dfrac{\sqrt{3} }{2}\right)$

$\implies \theta=30 \textdegree \pm360 \textdegree n, 330 \textdegree \pm360 \textdegree n$

$\implies \theta=30 \textdegree , 330 \textdegree$

$\implies \theta=30 \textdegree \pm360 \textdegree n, 150 \textdegree \pm360 \textdegree n$

$\implies \theta=30 \textdegree , 150 \textdegree$
