Answer:
p-q= -4
p=q-4
x^2 + px + q=0
=> x^2 + (q-4)x + q = 0
d= b^2-4ac
=(q-4)^2 - 4(1)(q)
= q^2 + 16 -8q - 4q
=q^2 -12q+16
given that D=16
q^2 -12q+16 = 16
=> q^2 -12q = 0
=> q^2 = 12q
=> q = 12q/q
=> q= 12
Therefore the value of q is 12 and the value of p is q-4 = 12-4= 8
Hope you understood............
S = 12a
s is the number of students
a is the number of adults
If so then it is not rational Square root of 2 is irrational and any number formed by multiplying or dividing it by a rational number is also irrational.
Answer:
<u>3/8</u>
Step-by-step explanation:
<u>Values we are given</u> :
- 16 flowers in total
- 6 lilies
<u>We know that</u> :
- Probability of selecting an object from a group of items = Number of objects / Number of items
Therefore,
- Probability of selecting a lily = Number of lilies / Number of flowers
- P = 6/16
- P = <u>3/8</u>
