The answer is 36. I know this because since one of the lengths of the room is 8, you take 80 and divide it by 8 which gives you 10. So now that you know the two side lengths you add. 10+10+8+8 which is 36.

Answer:

1. (-6, -5) to (-5, -4)

2. (-3, -4) to (-1, -1)

Step-by-step explanation:

Increasing intervals include the x- and y- points increasing.

PS: I don't really know how to present the answer so if you're gonna submit it for a test or smth pls improve on the formatting yourself based on the question (So sorry I didn't really understand the question about writing a list of intervals and separating them with a comma :P)

Find the value or values of p in the quadratic equation p2 + 13p – 30 = 0. A. p = 15, p = 2 B. p = –10, p = –3 C. p = 10, p = 3
DENIUS [597]
I hope this helps you




p^2+13p-30=0


p +15


p -2


(p+15)(p-2)=0


p= -15


p=2

Is either of these a polynomial?<br><br><br><br> 2 + s<br><br><br> X^2−√x+2
levacccp [35]
Hello there,

2 + s is a polynominal because it obeys at the rules.

However x^2 - square root of x + 2 isn't a polynominal because the variable is inside a radical for the square root.

Hope this helps !

Use the following information to answer this question and the next. Suppose that a recent poll of American households about pet
choli [55]

Answer:

28.75% probability that none of the three randomly selected households own a cat

Step-by-step explanation:

For each household, there are only two possible outcomes. Either it owns a cat, or it does not. The probability of a household owning a cat is independent of other households. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

34% owned a cat

This means that p = 0.34

Three households are selected

This means that n = 3

What is the probability that none of the three randomly selected households own a cat?

This is P(X = 0).

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 0) = C_{3,0}.(0.34)^{0}.(0.66)^{3} = 0.2875

28.75% probability that none of the three randomly selected households own a cat
