Treatment providers for problem gamblers report that men who approached them for intervention had lost a mean of $2,849 in the preceding four weeks, according to a 2002 report. Assume that the distribution of gambling losses is normally distributed with a mean of $2,849 and a standard deviation of $900. What proportion of males lost between $3000 and $4000? A.
pnorm(3999,2849,900)-pnorm(2999,284 9,900) = 0.3332

B.
pnorm(3999,2849,900)-pnorm(3000,284 9,900) = 0.3327

C.
pnorm(4000,2849,900)-pnorm(3000,284 9,900) = 0.3329

D.
pnorm(4000,2849,900)-pnorm(2999,284 9,900) =0.3333

Triangle xyz has vertices x(1,3), y(0,0)

Write the equation of a line that is perpendicular to the given line and that passes through the given point. –3x – 6y = 17; (6, 3) y = x – 9 y = 2x – 9 y = –2x – 9 y = x + 0 3. is the relationship shown by the data linear? if so, model the data with an equation. x y 1 5 5 10 9 15 13 20 the relationship is linear; y – 5 = (x – 1). the relationship is not linear. the relationship is linear; y – 5 = (x – 1). the relationship is linear; y – 1 = (x – 5). write an equation in point-slope form for the line through the given point with the given slope. (–10, –1); m = y + 10 = (x + 1) y – 1 = (x – 10) y – 1 = (x + 10) y + 1 = (x + 10) 5. write an equation for each translation of . 6.5 units up y + 6.5 = | x | y = | 6.5 x | y = | x | + 6.5 y = | x | – 6.5 6. write an equation for each translation of . 5.5 units right y = | x | + 5.5 y = | x – 5.5 | y = | x | – 5.5 y = | x + 5.5 | 7. which equation translates y = | x | by 8 units to the left? y = | x | – 8 y = | x | + 8 y = | x – 8| y = | x + 8|
