Answer:
Step-by-step explanation:
given,
initial price of buzz stock = $ 20 per share
after 20 days
stock price = $30 per share
after 40 days
the price = $35 per share
let say it is modeled by
y = ax² + b x + c
x = number of days
y = stock price
x = 0 y = 20
20 = a x 0 + b x 0 + c
c = 20
x = 20 y = 30
30 = 20² a + 20 b + 20
400 a + 20 b = 10...........(1)
x = 40 y = 35
35 = 40² a + 40 b + 20
1600 a + 40 b = 15...........(2)
solving equation (1)and (2)
a = - 1/160
b = 5/8
hence , the above equation is multipart function

<u>Answer:</u>
The hand moved 
of a complete turn.
<u>Step-by-step explanation:</u>
The hand moved from 3 to 12, that is, it moved:
12 - 3 = 9 hours
In a clock, 12 hours represent a complete turn.
∴ Using the unitary method:
12 hours ⇒ 1 turn
1 hour ⇒ 
turns
9 hours ⇒ × 9 = 
= turns (simplified)
∴ The hand moved of a complete turn.
Answer:
Probability of a dice rolling a number less than 3 is 2/6 = 1/3
Probability of dice spinning a number less than 6 is 5/6
Step-by-step explanation:
Number less than 3:
Chances of no. Being 1 and 2, not including 3, is 1/6 individually.
Hence, chances of no. Rolled being lesser than 3 is 1/6 + 1/6 = 1/3
Probability of no. Being smaller than 6 (lesser than 6) Aka spinning 1 or 2 or 3 or 4 or 5, not including 6 is (1/6) x 5 = 5/6
