Answer:

1,2

Step-by-step explanation:

f(x) always equals y. So basically, y = 4. The only factor that goes into 4 is 2, because 2 x 2 equals 4, and always 4 x 1 will equal 4.

The area of a circle is 9π in². What is the circumference, in inches? Express your answer in terms of \piπ
dangina [55]

Answer:

6\pi in

Step-by-step explanation:

The formula to find the area of a circle: \pi r^{2}, where r is the radius.

The formula to find the circumference (perimeter) of a circle: 2\pi r, where r is the radius.

1) To find the circumference of the circle, we need to find the radius (r) first. Since the area of the circle is given to us, we need to equate this to the formula to find the area of a circle.

9\pi =\pi r^2

Cancel the \pi by bringing it to the other side.

9 =\pi r^2 ÷ \pi

9 = r^2\\\sqrt{9} = r\\3 = r

2) Find the circumference of the circle by using the formula, 2\pi r.

=  2*\pi *3

= 6\pi in

Prove that every integer greater than 7 can be written by using 3's and 5's only. that is, for every n > 7 there exist non-ne
Taya2010 [7]
An integer may be a multiple of 3.
An integer may be 1 greater than a multiple of 3.
An integer may be 2 greater than a multiple of 3.

It is redundant to say an integer is 3 greater than a multiple of 3 (that's just a multiple of 3, we've got it covered).  Same for 4, 5, 6, 7...

Let's consider a number which is a multiple of 3.  Clearly, we can write 3+3+3+3+... until we reach the number.  It can be written as only 3's.

Let's consider a number which is 2 greater than a multiple of 3.  If we subtract 5 from that number, it'll be a multiple of 3.  That means we can write the number as 5+3+3+3+3+...  Of course, the number must be at least 8.

Let's consider a number which is 1 greater than a multiple of 3.  If we subtract 5 from that number, it'll be 2 greater than a multiple of 3.  If we subtract another 5, it'll be a multiple of 3.  That means we can write the number as 5+5+3+3+3+3+...  Of course, the number must be at least 13.

That's it.  We considered all the numbers.  We forgot 9, 10, 11, and 12, but these are easy peasy.

Beautiful question.

The probability distribution for a random variable x is given in the table X: -5,-3,-2,0,2,3 Probability: .17,.13,.33,.16,.11,.1
Ivan

Answer:

0.6 probability that -2 \leq x \leq 2

Step-by-step explanation:

The probability distribution is given in the table.

Probability that x is between -2 and 2.

Between -2 and 2, inclusive, we have -2, 0 and 2. So

P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2)

From the table:

P(X = -2) = 0.33, P(X = 0) = 0.16, P(X = 2) = 0.11. So

P(-2 \leq x \leq 2) = P(X = -2) + P(X = 0) + P(X = 2) = 0.33 + 0.16 + 0.11 = 0.60

0.6 probability that -2 \leq x \leq 2
