The histogram shows the results of a survey asking students how many video games they currently own. A histogram titled Video Game Ownership has the Number of video games on the x-axis and the number of students on the y-axis. 4 students have 0 to 9 games; 9, 10 to 19; 10, 20 to 29; 3, 30 to 39; 1, 40 to 49.

How many observations were used to create the display?

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

income. 10x+1300

expenses 3x+(1800+1500)

expenses 3x+3300

to break even:

income = expense,

10x + 1300 = 3x + 3300,

solve for x.
