So first of all you have to change 20% into 0.20 then do 0.20 x 96 and get 19.2 or 19.20
Answer:
x = -4/9
Step-by-step explanation:
-3(4x − 2) = 6x + 14
Distribute
-12x+6 = 6x+14
Add 12x to each side
-12x+6+12x = 6x+14+12x
6 = 18x+14
Subtract 14 from each side
6-14 = 18x
-8 =14x
Divide each side by 14
-8/14 = 14x/14
-4/9 = x
Answer:
Step-by-step explanation:
In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.
Using the formula above,
Substitute the value of m into the equation:
To find the value of b, substitute a pair of coordinates into the equation.
When x= 2, y= 5,
5= 3 +b
b= 5 -3
b= 2
Thus, the equation of the line is .
If about 20% of British children are deficient in vitamin and doctors test a group of elementary school children, the probability that the first vitamin d-deficient child is the 8th one tested is 4.19% determined using geometric distribution formula.
In probability and statistics, geometric distribution refers to the probability that first success would occurs after n number of trials and is given by:
P(X)=q^(x-1)p
Where p is the probability of success and q is (1-p)
In this case,
p=probability of children deficient in vitamin= 0.2
q= probability of children not deficient in vitamin= 0.8
Hence,
P(8)=0.8^(8-1)*0.2= 0.0419
Hence, the probability that 8th child is deficient is 4.19%
