40 weeks because you divide 500 by 4 which is 125 then you guess and check to make 40 multiplied by 125 is 5,000
Answer:
4x - 12
Step-by-step explanation:
Expand 8 - 4(-x + 5) as follows:
8 + 4x - 20
4x - 12 (First answer is the correct one)
Answer:
95%
Step-by-step explanation:
For a given sample data, the width of the confidence interval would vary directly with the confidence level i.e. more the confidence level, wider will be the confidence interval.
This is because the critical value associated with the confidence level(e.g z value) becomes larger as the confidence level is increased which results in an increased interval.
The confidence interval for a population proportion is given by the formula:
![p \pm z\sqrt{\frac{pq}{n} }](https://tex.z-dn.net/?f=p%20%5Cpm%20z%5Csqrt%7B%5Cfrac%7Bpq%7D%7Bn%7D%20%7D)
So, for a fixed value of p,q and n, the larger the value of z the wider will be the confidence interval.
Hence 95% confidence interval will be wider than 80% confidence interval.
Rational, because it is a repeating decimal. I believe that's the correct answer.
First isolate the x. Always remember that the way you do this is the opposite of the what is happening to the number you want to move.
You want to move the -5 from the left side to the right side by doing the opposite and adding it to both sides.
Like: 27x-5=-5+11
27x-5+5=11+5
So 27x=11 Continue to isolate the variable
