What is the sign of the product?

2 answers:

8 0

$= (0.3)(-9.2)(-8.1)(4.2)(-0.8) \\ = (-2.76)(-8.1)(4.2)(-0.8) \\ = (22.356)(4.2)(-0.8) \\ = (93.8952)(-0.8) \\ = -75.11616$

So, yeah the product is Nagative.

The simplest way is to count the number of NEGATIVE SIGNS in the problem before doing any multiplying If there are an ODD number of NEGATIVE TERMS the answer is NEGATIVE if an EVEN NUMBER the answer is POSITIVE In this problem there are 3 negative terms, so the answer is NEGATIVE after knowing the sign, just multiply the numbers without worrying about the sign, you already know it

Answer:

Yes, it is reasonable to expect that more than one subject will experience headaches

Explanation:

Notice that where it says "assume that 55 subjects are randomly selected ..." there is a typo. The correct statement is "assume that 5 subjects are randomly selected ..."

You are given the table with the probability distribution, assuming, correctly, the binomial distribution with n = 5 and p = 0.732.

p = 0.732 is the probability of success (an individual experiences headaches).
n = 5 is the number of trials (number of subjects in the sample).

The meaning of the table of the distribution probability is:

The probability that 0 subjects experience headaches is 0.0014; the probability that 1 subject experience headaches is 0.0189, and so on.

To answer whether it is reasonable to expect that more than one subject will experience headaches, you must find the probability that:

X = 2 or X = 3 or X = 4 or X = 5

That is:

P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5).

That is also the complement of P(X = 0) or P(X = 1)

1 - P(X = 0) - P(X = 1)

From the table:

P(X = 0) = 0.0014
P(X = 1) = 0.0189

Hence:

1 - P(X = 0) - P(X = 1) = 1 - 0.0014 - 0.0189 = 0.9797

That is very close to 1; thus, it is highly likely that more than 1 subject will experience headaches.

In conclusion, yes, it is reasonable to expect that more than one subject will experience headaches

A square has a side that measures 5.5 units. What is the area of a circle with a circumference that equals the perimeter of the

jonny [76]

Step-by-step explanation:

here first you have to find the perimeter of square

given that perimeter of circle is equal to perimeter of square,,,,, therefore with the perimeter of square you have to find the radius of the circle.....

now you have the radius of the circle so by applying the formula of area of circle the answer will be finded
