Answer:

Step-by-step explanation:
-Given the boundaries as 0.412 and 0.878
-
is the point estimate for the population proportion and is calculated as follows:

#The margin of error, ME can be calculated for the confidence intervals using the formula:

#The number of individuals in the sample is the product of the point estimate and population size:

Hence, there are 645 individuals in the sample.
The perpendicular bisector theorem gives the statements that ensures
that
and
are perpendicular.
The two statements if true that guarantee
is perpendicular to line
are;
Reasons:
The given diagram is the construction of the line
perpendicular to line
.
Required:
The two statements that guarantee that
is perpendicular to line
.
Solution:
From the point <em>C</em> arcs <em>E</em> and <em>D</em> are drawn to cross line
, therefore;
arcs drawn from the same radius.
is perpendicular to line
, given.
Therefore;
by perpendicular bisector theorem.

Answer:
1) 9:14
2)4:1
Step-by-step explanation:
You have to have all of the teachers compared to all of the adults (teachers included)
You have to simplify 12:3 and you get 4:1.
<span>To solve this, use the point - slope form formula
</span>Point D (-4, 2) and Point E (-1, 5)
<span>y - y1 = [(y2 - y1)/(x2 - x1)](x - x1)
y - 2 = [(5 - 2/-1 -(-4))](x + 4)
y - 2 = x + 4
y = x + 6
To answer this, input the values of points D or E into the equation and make sure that they answer the equation in part A.
</span>y = x + 6
2 = -4 + 6 = -2 so it satisfies the solution
Since the total degree of a triangle is 180, subtract 44 from 180 = 136. Divide it by two, and you get 68. I believe this is correct but don't take my word for it. Good luck!
