For which of these scenarios could you use the normal approximation to the binomial?

a. the number of free throws an 80% shooter will make in five attempts.
b. flip a coin 100 times and count the number of heads.
c. the number of bats who carry rabies if the frequency in your population is .8 and you select 4 bats.
d. the number of people who have type o blood if the frequency in your population is .7 and you randomly select 6 people.
e. the number of free throws an 80% shooter will make in six attempts.

huh? im pretty sure it is in 199

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

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.
