Answer:
The number of vials of type A insulin sold were _<u>21</u>__ and the number of vials of type B insulin sold were __<u>29</u>__.
Step-by-step explanation:
Let a = number of type A vials.
Let b = number of type B vials.
38.85a + 30.34b = 1695.71
a + b = 50
38.85a + 30.34b = 1695.71
(+) -38.85a - 38.85b = -1942.50
---------------------------------------------------
-8.51b = -246.79
b = 29
a + b = 50
a + 29 = 50
a = 21
Answer: The number of vials of type A insulin sold were _<u>21</u>__ and the number of vials of type B insulin sold were __<u>29</u>__.

</h2><h3>The confidence interval for population proportion is given by :_</h3>
Where : 
is the margin of error , n is the sample size , p is the sample proportion of success and 
is the significance level.
Given : Confidence level : 
Then , Significance level : 
Sample size : 
Sample proportion of respondents chose chocolate pie: 
Margin of error : 
Ax+by=c is the standard form
you are given the slope and a point, so first write the equation in point-slope form:
y-(-3)=2/3(x-6)
expand the equation: y+3=(2/3)x-4
(2/3)x-y=7 is the standard form
Using finite difference, the answer is cubic. Apologies if I’m wrong
I say go with -(1/2) ^ 750
