People of different ages were asked the question "Do you listen to audiobooks?” The bar graph below displays the percentage of "yes” responses for different age groups. A bar graph titled audiobook listeners has age on the x-axis and relative frequency on the y-axis. 13 to 17, 0.08; 18 to 25, 0.15; 26 to 35, 0.23; 36 to 45, 0.45; 46 and over, 0.47.

Is this graph misleading?
No, because the bars are all the same width.
No, because the scale starts at 0.
Yes, because the bars are not the same height.
Yes, because the scale does not start at 0.

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
