hichkok12 [17]3 years ago
4 0

Answer:

The area of a circle can be calculated by using the formula:

A = πr²

Step-by-step explanation:

I'm assuming that you are asking about how to calculate the area of a circle, so this formula would be it, where the symbol 'π' is pi, a number which never ends, but in calculations is typically rounded to 3.14. However, on your calculator you may have a button which you can press to find the area of a circle that way.

Is it easier to graph an equation in y-intercept form or standard form? Explain.​
Dafna1 [17]
Y-intercept form because it is more commonly used and easier to remember. The foundation of the y-intercept is easier to put in a graphing calculator also as it is already set to y=

Suppose you roll n ≥ 1 fair dice. Let X be the random variable for the sum of their values, and let Y be the random variable for
noname [10]

<u>Answer:</u>

X and Y are stochastically dependent RVs .

<u>Step-by-step explanation:</u>

Let ,

X = sum of the values that come up after throwing n (≥ 1) fare dice.

Y = number of times an odd number come up.

Let, n = 3

then, P(X =6) = p (say) clearly 0 < p < 1

and P (Y = 3) = \frac{1}{8}

And,

P( X = 6, Y = 3) = 0  ≠ P(X = 6) \times P(Y= 3)

Hence, X and Y are stochastically  dependent  RVs

The coordinates of A, B,and C in the diagram are A(p,4), B(6,1), C(9,q). What equation correctly relates p and q?
murzikaleks [220]
I don't see any diagram. So, I'll just wing it.

Value of q:
p, 6, 9 ⇒ there is a difference of 3. The sequence increases by 3. So, it can be assumed that the p is equal to 3. A(p,4) ⇒ A(3,4)

Value of q:
4, 1, q ⇒ there is a difference of 3. The sequence decreases by 3. So, it can be assumed that q is equal to -2. C(9,-2)
 
        p        q
A     3        4     ⇒ 3 + 4 = 7
B     6        1     ⇒ 6 + 1 = 7
C     9       -2    ⇒ 9 + (-2) = 7

Notice that the sequence has an equation of p + q = 7.
