A survey study is to be made to estimate the proportion of residents of a certain suburb who favor the construction of a public

lesya [120]

Answer: 601

Step-by-step explanation:

When the prior estimate of population proportion is not given , the formula we apply to find sample size :

$n=0.25(\dfrac{z^*}{E})^2$

, where z* = critical z-value

E=Margin of error

Given : Margin of error = 0.04

Confidence level = 95%

We know that , according to the z-table , the critical value for 95% confidence interval = z*= 1.960

Then, the required sample size : $n=0.25(\dfrac{1.960}{0.04})^2$

$n=0.25(49)^2$

$n=0.25(2401)=600.25\approx601$

Hence, the required minimum sample size = 601

What is the range of g(x) = 3|x − 1| − 1? A. (-∞, 1] B. [-1, ∞) C. [1, ∞) D. (-∞, ∞)

AVprozaik [17]

Answer:

B. [-1, ∞).

Step-by-step explanation:

g(x) = 3|x − 1| − 1

When x = 1 g(x) = 3(0) - 1 = -1.

As all negative vales of x will give positive values of |x - 1| then g(x) = -1 is its minimum value. The graph will be shaped like a letter V with the vertex at (1,-1).

Therefore the range is [-1, ∞).

Find the slope of the line whose equation is 17 + 3y = 7x.-7/317/3

Anastaziya [24]

Slope is 7/3

Step-by-step explanation:

Step 1: The equation of the line is 17 + 3y = 7x. Find the slope.

Slope intercept form is y = mx + b, where m is the slope.

⇒ 17 + 3y = 7x

⇒ 3y = 7x - 17

⇒ y = 7/3 x - 17/3

m = 7/3

⇒ Slope is 7/3
