Answer:
(5 x 4)= (3^2 - 4)= 4
Step-by-step explanation:
(5 x 4)=20,
(3^2 -4)= (9-4)
(20)=(5)=4
20/5=4
4=4
A study finds that out of every 400 babies born in the world, 28 have some kind of major birth defect. The simplest way to assign random numbers to conduct a simulation based on this statistic is to use 00-06 (7%) to indicate the babies with birth defects.
<h3>What is the rationale for the above?</h3>
Note that the total number of births is: 400
Total number of defective babies = 28
Hence, the fraction or ratio of this is:
28/400
= 7/100
= 7%.
This also means that 07-99 (93%) will represent the babies without birth defects.

Answer:
b
Step-by-step explanation:
Ok so first we find the equation that equals one variable.
2y = -x + 9
3x - 6y = -15
We solve for y.
2y = -x + 9
y = -x/2 + 9/2
Then we plug in this y value into the other equation to keep only one variable so we can solve for it.
3x - 6y = -15
3(-x + 9/2) - 6y = -15
-3x + 27/2 - 6y = -15
-9y + 27/2 = -15
-9y = 3/2
-y = 3/18
y = -3/18
Then we plug in this numerical y-value into the first equation which we found out by solving an equation for y.
y = -x/2 + 9/2
-3/18 = -x/2 + 9/2
-84/18 = -x/2
-x = 9 1/3
x = -28/3
Your answer would be (-28/3, -3/18)
Hope this helps!
