Plsss help Use the following information, to answer the following question.
Blair wants to know how long students spend on the bus each morning. She surveyed 100 random students who ride the bus to school. She found
that 60 students spend under 20 minutes on the bus. If her data is representative of the afternoon bus riders too, how many students would spend
less than 20 minutes on the bus on the way home if 450 students ride the bus in the afternoon

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.

answer is c

step-by-step explanation:

81/12=324/x

x=48

let's first notice, the center of the hyperbola is at the origin, since the focus points are equidistantly 3 units away from the origin, that also means that the distance "c" from the center to either focus is 3.

it should also be notable that, the traverse axis for this hyperbola is vertical, or namely over the y-axis and therefore, the positive fraction will be the one with y-variable.

the traverse "a" component or distance from the center to either vertex is not 2, is more than 2, so we can safely put it at √5 ≈ 2.24.

what are the answer choices given for this problem?
