1. Slope = 7

2. x-intercept = 6/7 = 0.85714

3. y-intercept = 6/ - 1 = -6.00000

Rearrange:

Rearrange the equation by subtracting what is to the right if the equal sign from both sides of the equation:

7x-y- (6) = 0

scoray [572]

Answer:

a. n=4148

b. n=3909

c. The sample size is smaller if a known proportion from prior study is used. The difference in sample sizes is 239

Step-by-step explanation:

a. For sample where no preliminary estimate is given, the minimum sample size is calculated using the formula:

n=p(1-p)(\frac{z}{ME})^2

Where:

  • ME=Margin of error
  • p= is the assumed proportion

#Let p=0.5, substitute in the formula to solve for n:

n=0.5(1-0.5)\times (2.576/0.02)^2\\\\=4147.36\approx 4148

Hence, the minimum sample size is 4148

b. If given a preliminary estimate p=0.38, we use the same formula but substitute p with the given value:

n=p(1-p)(z/ME)^2\\\\=0.38(1-0.38)(2.576/0.02)^2\\\\=3908.47\approx3909

Hence, the minimum sample size is 3909

c. Comparing the sample sizes from a and b:

n_{0.5}>n_{0.38}\\\\n_{0.5}-n_{0.38}=4148-3909=239

Hence, the actual sample size is smaller for a known proportion from prior a prior study.

A man travelled 3/5 of his journey by rail, 1/4 by a taxi, 1/8 by a bus and the remaining 2 km on foot.What is the length of his
docker41 [41]
Hello friend,here is the solution

<span>Let x be the total distance </span>

<span>Distance travelled by rail = 3/5 x </span>

Distance travelled by taxi = 1/4 x

<span>Distance travelled by bus = 1/8 x </span>

<span>The equation we obtain is </span>
========================

<span>x = 3/5 x + 1/4 x + 1/8 x +2 </span>
