Answer:

5z^3\sqrt{42}

Step-by-step explanation:

You can multiply and put everything under one square root to get \sqrt{1050z^6}. You can take out (5z^3)^2 from the square root to get \boxed{5z^3\sqrt{42}}

Suppose that the proportions of blood phenotypes in a particular population are as follows: A B AB O 0.48 0.13 0.03 0.36 Assumin
Serggg [28]

Answer:

P(O and O) =0.1296

P=0.3778

Step-by-step explanation:

Given that

blood phenotypes in a particular population

A=0.48

B=0.13

AB=0.03

O=0.36

As we know that when A and B both are independent that

P(A and B)= P(A) X P(B)

The probability that both phenotypes O are in independent:

P(O and O)= P(O) X P(O)

P(O and O)= 0.36 X 0.36 =0.1296

P(O and O) =0.1296

The probability that the phenotypes of two randomly selected individuals match:

Here  four case are possible

So

P=P(A and A)+P(B and B)+P(AB and AB)+P(O and O)

P=0.48 x 0.48 + 0.13 x 0.13 + 0.03 x 0.03 + 0.36 x 0.36

P=0.3778

Which is an extraneous solution of the exponent x+sqrtx=6
zheka24 [161]
First, we can simplify it down. 
x = (-x + 6)^2
Then, you should have x - (x^{2} - 12x + 36).
Factor it to get x = 4 or 9. 4 works in the original equation but 9 does not.

What is the solution to 4+5e^x+2 =11
Nezavi [6.7K]

Answer:

x =0

Step-by-step explanation:

4+5e^x+2 =11

Combine like terms

6 + 5e^x =11

Subtract 6 from each side

6-6 + 5e^x =11-6

5 e^x = 5

Divide by 5 on each side

5 e^x /5 = 5/5

e^x = 1

Take the natural log on each side

ln (e^x) = ln(1)

x = ln(1)

x =0
