<span>Importance should be
given to all the information’s
already given in the question.</span>Number of fossils that Elmer has = 300
Percentage of snail shell fossils = 21%
Then
Number of snail shell fossils that Elmer has = (21/100) * 300
= 21 * 3
= 63
So Elmer has 63 snail shell fossils.I hope the procedure
is absolutely clear to you and the answer is also correct. Following this procedure
it will be possible for you to solve such question with ease in future.<span>

Answer:
C) z = 2.437
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, is the value tested at the null hypothesis, is the standard deviation and n is the size of the sample.
In this problem, we have that:
So
it would be 150 degrees because every angle equals 180 degrees.
1) slope=3 and y-int.=-5
2) slope=2 and y-int.=-6
3) slope=-6 and y-int.=1/2
4) slope=-7 and y-int.=5/2
5) slope=1/2 and y-int.=7
6) slope=3/4 and y-int.=8
7) slope=-2/3 and y-int.=-1/3
8) slope=-1/8 and y-int.=-3/8
9) slope=2/3 and y-int.=5
10) slope=-2/7 and y-int.=-1
11) slope=-3 and y-int.=6
12) slope=4 and y-int.=7
Hope this helps!
