Answer:
3.
Step-by-step explanation:
Implicit differentiation:
x^2 y + (xy)^3 + 3x = 0
x^2 y + x^3y^3 + 3x = 0
Using the product rule:
2x* y + x^2*dy/dx + 3x^2 y^3 + x^3* (d(y^3)/dx) + 3 = 0
2xy + x^2 dy/dx + 3x^2 y^3 + x^3* 3y^2 dy/dx + 3 = 0
dy/dx(x^2 + 3y^2x^3) = (-2xy - 3x^2y^3 - 3)
dy/dx= (-2xy - 3x^2y^3 - 3) / (x^2 + 3y^2x^3)
At the point (-1, 3).
the derivative = (6 - 81 - 3)/(1 -27)
= -78/-26
= 3.
Answer:
Whole number
Step-by-step explanation:
That's only because it is just 1 number that is gonna be there and i did some research too
Answer:
b. Yes, probability is > 0.05
Step-by-step explanation:
We have to find P(X=3) and if the probability is below 0.05 then the it would be unusual and if it isn't below 0.05 we believe that the data from the blood program.
This probability can be found bu binomial distribution with parameters n=6
and p=0.4.
P(X=x)=nCx(p^x)(q^n-x)
where q=1-p=1-0.4=0.6.
P(X=3)=6C3(0.4^3)(0.6^3)
P(X=3)=20(0.064)(0.216)
P(X=3)=0.27648
As the probability that the three have a blood group is greater than 0.05, so, we believe that the data from the blood program.
Answer:
Step-by-step explanation:
use pemdas to find your answer, first parentheses, exponents, multiplication, division, addition, subtract. in that order you will find your answer.
It's rational because it is a repeating decimal. 20/6=3.33333333333333...
