A two-way frequency table is shown below that displays the relationship between the region of the country in which people live and the type of music preferred. We took a sample of 193 people and recorded the following results: Country Music Rock Total
West 26 15 41
East 24 22 46
South 7 33 40
North 41 25 66
Total 98 95 193

What is the probability (rounded to the nearest whole percent) that a randomly selected person is from the southern region of the country if he or she prefers rock music? (4 points)

35%
33%
83%
17%

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

i think is g(1)=-1.

hope that i can

the answer is ! ?
