X/2.7 + 3.6=4.8 solve for x

weqwewe [10]

Answer:

3.24

Step-by-step explanation:

1) minus the whole number, 3.6 from both sides:

x/2.7 +3.6 = 4.8 -----> x/2.7 = 1.2

2) multiply both sides by 2.7 to get the x value on its own:

x/2.7 = 1.2 -------> x = 3.24

3) finally x is on its own with a value on the other side... x = 3.24

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.
