Individuals who have a certain gene have a 0.46 probability of contracting a certain disease. suppose that 913 individuals with the gene participate in a lifetime study. what is the standard deviation of the number of people who eventually contract the disea

15.06

Step-by-step explanation:

Given : The number of individuals participated in a lifetime study :

The probability of individuals with certain gene of contracting a certain disease :

Now, the standard deviation of the number of people who eventually contract the disease is given by :_

Hence, the  the standard deviation of the number of people who eventually contract the disease = 15.06

this might get deleted, sorry. it has to be an actual question. if you really wanted to give someone free points, ask a question like "why does the sky look blue, and the sun is yellow to our eyes? "

step-by-step explanation:

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
