Answer:

increasing the radius makes the circle larger. (Answer B)

Step-by-step explanation:

The formula for the area of a circle is A = πr². Hence, Area of a Circle depends solely on the variable r and the constant of proportionality π.

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]

Answer:

X and Y are stochastically dependent RVs .

Step-by-step explanation:

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

What is 115% of 25? A. 46. B. 27.73. C. 28.75. D. 27.75

gladu [14]

100% = 25 so 25 + 15%
15% = .25 (25 divided by 100= .25) x 15 = 3.75

25 + 3.75 = 28.75 so C
