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

can you put the picture up?

step-by-step explanation:

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

b if for most of the graph

d if y intercept

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
