Use the slope formula to find the missing coordinate: R(0,_), S(-4,2) m=5

Delicious77 [7]

Answer

The missing value is 22

step-by-step explanation

The slope formula is

$m = \frac{y_2 - y_1}{x_2 - x_1}$

From the question,

m=5

$x_2=-4$

$y_2=2$

and

$x_1=0$

We substitute these values to get,

$5= \frac{2 - y_1}{ - 4- 0}$

Simplify

$5= \frac{2 - y_1}{ - 4}$

$5 \times - 4=2 - y_1$

$- 20=2 - y_1$

$- 20 - 2=- y_1$

$22= y_1$

$y_1 = 22$

The missing value is 22

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.
