Describe a relationship in which it would be reasonable to have a negative number in the domain or
Aliun [14]

Answer:

Relationship between temperature at different times of the day during the Winter period in places like Alaska and Minnesota in the USA.

Step-by-step explanation:

An example of a relationship that would have a negative number in the domain or range would be the relationship between the temperature at different times of the day during the snow period in the winter. It's well known that in places like Alaska and Minnesota in the USA, that during the winter when there's very heavy snow, the average temperature is usually below 0°C. The temperature is the dependent variable and is most likely negative in those 2 states and thus the range would have negative numbers.

I would like to have an answer for this thanks!

The final amount of the compound interest after 6 years would be $ 294, 122, 500

<h3>How to determine the final amount</h3>

The formula for the final amount is given as;

A = P( 1 + \frac{r}{n}) ^n^t

Where

A = final amount

P = principal interest

r = interest rate

n = number of times

t = time of periods

We have,

A = 2500 ( 1 + \frac{6}{1}) ^1^*^6

A = 2500 ( 7)^6

A = 2500 × 117, 649

A =$ 294, 122, 500

Thus, the final amount of the compound interest after 6 years would be $ 294, 122, 500

Worldwide, the proportion of babies who are boys is about 0.51 . Let the random variable X represent the number of boys in five
solmaris [256]

Answer:

mean = 2.55

Standard deviation = 1.118

Step-by-step explanation:

Probability of babies who are boys

P = 0.51

Then we have q = 1-p

= 1-0.51

= 0.49

We have n = 5

We calculate the mean as:

np

= 0.51x5

= 2.55

Therefore mean = 2.55

The standard deviation

= √variance

= √npq

= √0.51x5x0.49

=√1.2495

= 1.118
