The correct answer is A. Not only does $250 a week equal $1000 a month but the commission is also higher.
first job: $250wk = $1000 Month + .045 commission
= $12000 year + .045 commission
second job = $1800 Month + .03 commission
= $21600 year + .03 commission
commission based on sales of $1,000,000
1,000,000 times .045 = $45000
1,000,000 times .030 = $30000
FIRST JOB: $12,000 + $45,000 = $57,000
SECOND JOB: $21,600 + $30,000 = $51,600
The answer is definitely A.
Answer:
When to lines intersect they create four angles. Each angle is opposite to another and form a pair of what are called opposite angles. Angles a and c are opposite angles. Angles b and d are opposite angles. Opposite angles are equal.
Answer: I. True
II. True
III. True
Step-by-step explanation:
Uniform probability distributions, this are probability distributions which have equally likely outcomes. There are two known types of uniform distributions:
1. discrete
2. continuous.
In the first type of distribution, each outcome is discrete. In a continuous distribution, outcomes are continuous this means they are usually infinite.
Answer: 16590
Step-by-step explanation:
The formula we use to find the sample size is given by :-
, where p = prior estimate of population proportion.
= Critical z-value (Two- tailed)
E= Margin of error .
Let p be the population proportion of cyanobacteria.
Given : E = 0.01
Critical value for 99% confidence interval : ![z^*=2.576](https://tex.z-dn.net/?f=z%5E%2A%3D2.576)
If Ian does not want to rely on previous knowledge , then we assume p=0.5 because the largest standard error is at p=0.5.
Now, the required sample size = ![n=0.5(1-0.5)(\frac{2.576}{0.01})^2](https://tex.z-dn.net/?f=n%3D0.5%281-0.5%29%28%5Cfrac%7B2.576%7D%7B0.01%7D%29%5E2)
![n=0.25(257.6)^2=0.25(66357.76)=16589.44\approx16590](https://tex.z-dn.net/?f=n%3D0.25%28257.6%29%5E2%3D0.25%2866357.76%29%3D16589.44%5Capprox16590)
Required sample size = 16590
-(3/4) (12)+1 = -9+1=. -8
