Acarpet manufacturer is inspecting for flaws in the finished product. if there are too many blemishes, the carpet will have to be destroyed. he finds the number of flaws in each square yard and is interested in the average number of flaws per 10 square yards of material. the sample mean, x, for the 10 square yards will have what type of distribution? a. normal distributionb. neither of thesec. binomial distribution

Neither binomial nor normal distribution

Step-by-step explanation:

In binomial distribution Sumner of trials are fixed and there is only two outcomes either success or failure

But in this question there are no fixed trials and outcomes is not proper so this is not a binomial distribution.

In normal distribution there is information of mean and variance which is also not give in the question so it is also nit a normal distribution

So it is neither binomial nor normal distribution

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.
