Given,

HCF of two numbers = 40

Product of two numbers = 52800

LCM of two numbers =?

Formula required,

HCF × LCM = product of two numbers

Calculation,

Using formula

→ HCF × LCM = product of two numbers

Color-blindness is any abnormality of the color vision system that causes a person to see colors differently than most people, o
creativ13 [48]

Answer: c) All of the above

Step-by-step explanation:

a) X=the number of color-blind males of the randomly chosen 20 individuals

Thus, X is binomial with n = 20 and p = 0.08.

Y represents the number of color-blind females of the randomly chosen 40 individuals

Thus, Y is also binomial with n = 40 and p = 0.01.

b) However, Z represents the total number of color-blind  which is 60. The probability of being color-blind is not equal among all individuals as it is for X (0.08) and Y (0.09). Thus, Z is not binomial.

In conclusion both a and b are correct, which gives the correct answer number c) all of the above.

3(2x+14)divided by w-y if w=8,x=5,y=1 how do i solve this
Viktor [21]
\frac{3 (2x + 14)}{w - y}
w = 8, x = 5, y = 1

You have to first substitute every variable into its spot in the equation.

<span>\frac{3 (2x + 14)}{w-y}
</span><span>\frac{3 (2*5 + 14)}{8 - 1}
</span>
Then solve.

\frac{3 (28)}{7} = \frac{84}{7} = 12
