In the equation f(n) = 2n - 7
f(11) = 15
Answer:
1. So the porpotion should be 25/100 = x/120
You have this because you know that 25% of the dogs who go to ABC veterinarian need a rabies booster. So 100% of the dog should be 120 dogs, and now our job is to find how many dogs make up 25% percent of the total number.
According to our porpotion, we have:
(120 . 25)/100 = 30 (dogs)
Another way of understanding this is that you have to find 25% of the total amount, so just take that total number and multiply it with 25% or 25/100 which is 0.25 as well, that's why we multiply it with 25 first and then divide it to 100 later.
2.
*I guess there is no need of explaining it
0.9 × 550 = 495
2.8 X 10^-8 (........characters space so that I can post this..)
Answer
hello :
note : The equation of a linear function in point-slope form is : y – y1 = m(x – x1)
The point is A (x1 , y1)
Step-by-step explanation:
in this exercice : m = 5 x1 = 0 y1 = -3
the equation of a line in slope-intercept form for a line is :
y - ( -3) = 5 ( x - 0)
y +3 = 5 ( x - 0)
Answer:
0.85 ( lowest value proportion to vaccinate )
Step-by-step explanation:
Using the herd immunity relationship
Vc = E - ( E / Ro )
Vc = critical vaccination level
E = vaccine effective against the transmission = 1
Ro = Basic reproduction number
lets assume the effectiveness of the transmission = 100% = 1
lets assume the
Vc = 1 - ( 1 / 3 ) = 67%
but the lowest value proportion to vaccinate = 85%
