The system of equations that can be used to determine the number of small tables and the number of large tables the designer will make is:
y -x = 8
$12y - $6x = $236
<h3>Defining the variables </h3>
Let:
x = number of large tables the designer can make.
x = number of small tables the designer can make.
<h3>Simultaneous equations</h3>

Answer:
Step-by-step explanation:
Given that in the general population in the US, identical twins occur at a rate of 30 per 1,000 live births. A survey records 10,000 births during Jan 2018 to Jan 2019 and found 400 twins in total.
From the above we find that population proportion is 0.03 and observed sample proportion is 0.04
So option a) is wrong
b) Correct
c) correct
d) Wrong
e) wrong
f) wrong
g) incomplete sentence
h) wrong
Percent decrease = (original number - new number) / original number....* 100
= (45 - 27.5) / 45.....* 100
= 17.5 / 45....* 100
= 0.3888 * 100
= 38.9 % decrease <== thats rounded
.6 divided by 10 is .06 so .6 is 10 times more than .06. Hope this helps!
