Answer:
Vales of a =3 and b = 6
Step-by-step explanation:
Given that:
.....[1] where a and b are positive integers
we can write 81 and 24 as;


We have [1] as;

Using power rules;

which implies a = b
then;


On comparing both sides we have;
a = 3 and

⇒
Therefore, the value of a and b are, 3 and 6
Answer:
y=2x+1
Step-by-step explanation:
Y intercept is 1 and slope is 2/1
You must know that % is a number out of 100.
Therefore given 91/100 trusted DNA surveying, we know as a percentage this is 91% from the equation below:
(91/100)*100=91
We can conclude that 1%=1 person.
Although the difference is only 1 (91-90=1), the actual proportion of people who trust DNA testing is larger than the 90% by 1%.
