The aggregate annual rainfall at a given location is modeled as a random variable, resulting in a sequence of random variables {

V1, V2, V3, ...} for years 1, 2, 3,.... Assume the V's are independent, lognormally-distributed random variables with a mean value of 32in, and a coefficient of variation of 50%. It is desirable for the annual rainfall to be in the range between 15in and 50in. If this fails to be the case for multiple years, this can have adverse environmental and economic consequences.A) Find the probability a = P(15in < Vi \leq 50in).
B) For an arbitrary ten-year interval, nd the probability that the rainfall will not be in the desired range for at least three of the years in the interval.

Zinaida [17]

Answer:

R = rows

C = columns

The chairs will be arranged in a way such that R * C \geq 70

We know that R \leq 20

70 / 20 = 3.5; however, you can't have half of a chair.

So find all the factors of 70 which don't exceed 20.

1, 70

2, 35

<h2>5, 14</h2><h2>7, 10</h2><h2></h2><h2>There are four ways that Brooke can set up the chairs:</h2><h2>5 rows of 14</h2><h2>7 rows of 10</h2><h2>10 rows of 7</h2><h2>14 rows of 5</h2>

HELP PLEASE WILL GIVE BRAINLIEST WORTH 50 POINTS
Alja [10]

Answer:

y = 8.13 x -16125.713


hope it helps

Step-by-step explanation:

Sum of X = 14004

Sum of Y = 977

Mean X = 2000.5714

Mean Y = 139.5714

Sum of squares (SSX) = 53.7143

Sum of products (SP) = 436.7143

Regression Equation = ŷ = bX + a

b = SP/SSX = 436.71/53.71 = 8.13032

a = MY - bMX = 139.57 - (8.13*2000.57) = -16125.71277

ŷ = 8.13032X - 16125.71277

Please give me the correct answer.Only answer if you're very good at math.​
GaryK [48]

Answer:

-9 = 0.45m

Step-by-step explanation:

0.45m - 9 = 0.9m

  • ^ Subtract 0.45m from BOTH sides. so 0.9m - 0.45m... etc
  • Why? So that we can make the equation less complicated. Our goal is to isolate the variable m to be on one side of the "=" sign by itself
  • That will equal to:

-9 = 0.45m     <-- ANSWER
