<h3><u>given</u><u>:</u></h3>
each interior angle= 168°
<h3><u>to</u><u> </u><u>find</u><u>:</u></h3>
the number of sides the polygon has.
<h3><u>solution</u><u>:</u></h3>
180- 360/n= 168
12= 360/n
n= 360/12
n= 30
<u>therefore</u><u>,</u><u> </u><u>the</u><u> </u><u>polygon</u><u> </u><u>has</u><u> </u><u>30</u><u> </u><u>sides</u><u>.</u>
Answer:
Step-by-step explanation:
Given that the mean incubation time for a type of fertilized egg kept at a certain temperature is 25 days.
Let X be the incubation time for a type of fertilized egg kept at a certain temperature is 25 days.
X is N(25, 1)
a) Normal curve is in the attached file
b) the probability that a randomly selected fertilized egg hatches in less than 23 days
=
we convert x into Z score and use std normal distn table to find probability

i.e. we can say only 2.5% proportion will hatch in less than 23 days.
Step-by-step explanation:
do 590 divided by 90 if that doesn't work multiply it
a/c = d/a
you would cross multiply to get aa = cd
aa = a^2
so you would have a^2 = cd
The answer is 24 now goodluck with your homework
