I NEED HELP ASAP

SVEN [57.7K]

Alright, lets get started.

If the polygon measures 45 degree exterior angle and we are asked to find number of sides, there is a formula for that.

$\frac{360}{n}$ = value of exterior angle

Where n is number of sides of ploygon

$\frac{360}{n} = 45$

Multiplying n into both sides

$\frac{360}{n} * n = 45 n$

$360 = 45 n$

Now divide 45 in both sides

$\frac{360}{45} = \frac{45n}{n} = n = 8$

n = 8

Means number of sides of polygon is 8, hence its Octagon. Answer

Now we have given 45 exterior angle hence interior angle would be

180 - 45 = 135°

So, sum of all interior angles would be = number of sides * interior angle

sum of all interior angles would be = $8 * 135 = 1080$

Hence sum of all interior angles would be 1080°. Answer

Hope it will help :)

Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us.

mestny [16]

For a binomial experiment in which success is defined to be a particular quality or attribute that interests us, with n=36 and p as 0.23, we can approximate p hat by a normal distribution.

Since n=36 , p=0.23 , thus q= 1-p = 1-0.23=0.77

therefore,

n*p= 36*0.23 =8.28>5

n*q = 36*0.77=27.22>5

and therefore, p hat can be approximated by a normal random variable, because n*p>5 and n*q>5.

The question is incomplete, a possible complete question is:

Suppose we have a binomial experiment in which success is defined to be a particular quality or attribute that interests us.

Suppose n = 36 and p = 0.23. Can we approximate p hat by a normal distribution? Why? (Use 2 decimal places.)

n*p = ?

n*q = ?

If the length of the side of a square is 6 cm,then the area will be equal to ________

Feliz [49]

Answer:

36 centimeters squared.

Step-by-step explanation:

Use the formula for the area of a square.

$A=s^2$

$A=(6)^2$

$A=6 \times 6=36$

Solve the equation: 7x = 42. <br> A. x = 6<br> B. x = – 6<br> C. x = 7<br> D. x = – 7

OlgaM077 [116]

If you would like to solve the equation 7 * x = 42, you can calculate this using the following step:

7 * x = 42 /7
x = 42 / 7
x = 6

The correct result would be A. x = 6.
