Answer:
The sample should be as large as 480
Step-by-step explanation:
Probability of having a flu, p = 43/334
p = 0.129
Margin Error, E = 0.03
Confidence Interval, CI= 95%
At a CI of 95%, ![z_{crit} = 1.960](https://tex.z-dn.net/?f=z_%7Bcrit%7D%20%3D%201.960)
The sample size can be given by the relation:
![n = p(1-p)(z/E)^{2}](https://tex.z-dn.net/?f=n%20%3D%20p%281-p%29%28z%2FE%29%5E%7B2%7D)
![n = 0.129(1-0.129)(1.960/0.03)^{2} \\n = 479.59\\n = 480](https://tex.z-dn.net/?f=n%20%3D%200.129%281-0.129%29%281.960%2F0.03%29%5E%7B2%7D%20%5C%5Cn%20%3D%20479.59%5C%5Cn%20%3D%20480)
Diagonals of a rhombus
In any rhombus, the diagonals (lines linking opposite corners) bisect each other at right angles (90°). That is, each diagonal cuts the other into two equal parts, and the angle where they cross is always 90 degrees.
Answer:
14:42
Step-by-step explanation:
As we got 2 to get to 14, that means that we need to times by 7. Then we times the 6 by 7 to get the answer of 42.
We know that
p(x) and f(x) ------------> both are defined by the equation of a straight line
g(x)----------> is a grade 2 or higher function
see the attached figure<span>Part A: What is the solution to the pair of equations represented by p(x) and f(x)?
the solution is the intersection both graphs
the solution is the point (-2,-3)
the answer part A) is the point </span>(-2,-3)
<span>Part B: Write any two solutions for f(x)
for x=-6 f(-6)=5
for x=-3 f(-3)=-1
</span><span>Part C: What is the solution to the equation p(x) = g(x)?
</span>the solution is the intersection both graphs
the solution is the point (0,2)
