Answer:
B. (-7 +/-√33) / 4
Step-by-step explanation:
2x2 + 7x + 2 = 0
x = [-7 +/- √(7^2 - 4*2*2)] / 2*2
x = -7/4 +/- √(33) / 4
= (-7 +/-√33) / 4
Answer:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of 
.
The margin of error is of:
In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.
This means that 
95% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
Margin of error:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
Answer:
1/5
Step-by-step explanation:
5 baseballs to 25 softballs
=
1 baseballs to 5 softballs in simplest form
First we need a point (x,y) : (A, 7)
<span>Now slope (from f'(A)) = 15 </span>
<span>Next, the equation (using point slope formula) </span>
<span>y - 7 = 15 (x -A) </span>
<span>y = 15 (x - A) + 7 </span>
<span>Now in the x spot we put 'A-.01' </span>
<span>y = 15 ( A - .01 - A) +7= 15(-.01) +7 = -.15+ 7 = 6.85
hope this helps</span>
