Researchers in a certain country investigated how having daughters influences voting on women's issues by members of the federal government. the researchers use voting records of each member of the federal government to compute an index score, where higher scores indicate more favorable voting for women's rights. the researchers modeled the index score (y) as a function of the number of daughters (x) a voting member has. data collected for the 455 members of the federal government last year were used to fit the straight-line model, e(y) = beta_0 + beta_1 x. complete parts a through c below. a. if it is true that having daughters influences voting on women's issues, will the sign of beta_1 be positive or negative? explain. positive, because if the claim is true, then index score would increase as the number of daughters increases. b. the following statistics were reported in the article: beta_1 = 0.24 and s_beta_1 = 0.39. find a 99% confidence interval for beta_1. a 99% confidence interval is (round to three decimal places as needed.) c. use the result, part b, to make an inference about the model. since the interval (1) there is (2) evidence to conclude that having daughters influences voting on women's issues. contains only positive values insufficient contains zero sufficient

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
