Elena-2011 [213]

Answer: Firstly in this question, we need to solve for

which is the part of the distribution of which we not looking for.

we can do this with the sum:

−

0.76

0.24

0.76

we also know that our Standard Normal Distribution is symmetric, so we must divide that

to be split on either side of our distribution. so we solve for:

0.24

0.12

then we find a correlating

-score for the value

0.12

and we get that

−

1.175

and

1.175

This becomes easier to understand when visualized, so observe how we do this sum.

Solomon needs to justify the formula for the arc length of a sector. Which expression best completes this argument?The circumfer

Archy [21]

Answer:

$\frac{360}{n}$

Step-by-step explanation:

Given:

The above statements

Required

Complete the above statements

Considering the third statement in the question;

First, it should be noted that a circle is a full sector that measures 360 degrees

Assuming the circle is divided by a central angle of 180, the number of sectors formed will be;

$\frac{360}{180} = 2\ sectors$

Further assume the circle is divided by a central angle of 90, the number of sectors formed will be;

$\frac{360}{90} = 4\ sectors$

Similarly, if the circle is divided by a central angle of n, the number of sectors formed will be;

$\frac{360}{n}$

Hence, from the list of given options; $\frac{360}{n}$ fills the gap correctly
