A persons height in centimeters and that same persons height in inches... When the input is in centimeters you can convert to inches which is actually a function. Also this was the only one that had any relation to each other like at all

The answer is the third choice.

In a function, each input has to be paired with exactly one output.

For example, in the first choice, there could be 40 people with different heights and at the same age. That would not work, because then (12, 52) and (12, 64) and a thousand other combinations could work.

If you eliminate each choice like this, the only thing left is the third choice.

Hope this helped!

Seven customers enter a clothing store and are observed to determine if they will make a purchase. The store owner states that t

blondinia [14]

Answer: Mean = 5.25

Variance = 1.3125

Standard deviation = 1.456

Step-by-step explanation:

The mean and variance of a binomial distribution with parameters n (number of trials) and p ( the probability of getting success in each trial) is given by :-

$\text{Mean}=np\\\\\text{Variance}=np(1-p)$

Given : The total number of enter a clothing store : n=7

The probability of a customer making a purchase= 0.75

Now,

$\text{Mean}=7(0.75)=5.25\\\\\text{Variance}=7(0.75)(0.25)=1.3125\\\\\Rightarrow\ \text{Standard deviation}=\sqrt{1.3125}=1.14564392374\approx1.1456$

Find the equation of the circle that is shifted 5 units to the left and 2 units down from the circle with the equation x^2+y^2=1

marysya [2.9K]

Shifting a circle results to changes in the coordinates of the circle. For instance, if the coordinates of the center of the circle is taken to be (0,0), the new coordinates will be [(0+5),(0+2)] after shifting. The equation of the circle will also change with the same margin.

That is, the new equation will be;
(5+x)^2+(2+y)^2 =19

Notice, only the coordinates changes.
