Answer:
given zeroes are 1/2 &-3/7
let a=1/2 & b=-3/7
the formula of forming a quadratic equation when zeros are given is x²-(a+b)x+ab
a+b = 1/2+(-3/7)=7-6/14= 1/14
ab=1/2×(-3/7)=-3/14
=> equation is = x²-(1/14)x-3/14

A whole pizza has 8 slices. 1/4=25%. 25% of 8 is 2.
Y=3x+2
you use y=mx+b and substitute (0,2) for x and y in the equation and also the 3 for the m
The event space of getting exactly one tail is {HT, TH}
The sample space is {HH, HT, TH, TT}
There are two ways to get exactly one tail, out of 4 total possible outcomes.
So 2/4 = 1/2 is the answer
Answer:
Step-by-step explanation:
The population in 1981 is 46 million.
In 2011, the population increased to 53 million.
The increase in population is (53 -46)million =7 million
Now we express 7 million as a percentage of 46 million
=15.22%
