lozanna [386]

Answer:

(n-2)×180=1080

180n -360=1080

180n = 1080+360

180n =1440

dividing by 180

n=8

hence it is a regular polygon with 8 sides .I.e it is an octagon

Step-by-step explanation:

we are given the total interior angles in the polygon and we know that the formula to find the total interior angles of a polygon is (n-2) ×180

where n is the number of sides

The normal body temperature of any human body is considered to be 98.6$^\circ \ F$. But there is a constant debate about the body temperature of a long held standard to the body temperature.

It is given that :

Null hypothesis and alternate hypothesis :

$H_0 : \mu = 98.6$

And $H_A : \mu > 98.6$

n is given as = 180

Test statistics = 3.64

Prove = 0.018 < α = 0.05 (let reject null hypothesis for α = 0.05 )

Therefore, their results are statistically significant and the result is unlikely due to chance alone.

the basketball court in the park is rectangle two of the sides are 84 feet long and the other two sides are 50 ft long what is t
butalik [34]
Hello!

So, we know that the length of the rectangular basketball court is 84 ft, and the width is 50 ft.

The formula for perimeter of a rectangle is:

P = 2l + 2w

This means that we need to multiply the length by two and the width by two as well.

Substitute:

P = 2(84) + 2(50)

P = 168 + 100

P = 268 ft

ANSWER:

The perimeter of the basketball court is 268 feet long.
