In a certain city, the daily consumption of water (in millions of liters) follows approximately a gamma distribution with α = 2
Ne4ueva [31]

Answer:

The probability that on any given day the water supply is inadequate 0.1991

Step-by-step explanation:

Given

α = 2 and β = 3

As per Gamma distribution Function

P(X>9)= 1-P(X\leq 9)\\

Expanding the function and putting the given values, we get -

[tex]1 - \int\limits^9_0 {f(x;2,3)} \, dx \\1- \int\limits^0_0 {\frac{1}{9}xe^{\frac{-x}{3} } \, dx\\\\= 1- \frac{1}{9} [x(-3e^{\frac{-x}{3}}) -\int\limits {(-3e^{\frac{-x}{3}})} \, dx]^9_0= 1- 1/9 [x(-3e^{\frac{-x}{3}}) -9e^{\frac{-x}{3}})} \, dx]^9_0\\1-((\frac{-1}{3} *9*e^({\frac{-9}{3}})- e^(\frac{-9}{3}))- ((\frac{-1}{3} *0*e^(\frac{-9}{3})-e^{\frac{-0}{3}})\\1-((-3e^{\frac{-9}{3} }-e^{\frac{-9}{3}}-(0-1))\\1-(1-4e^{-3})\\1-(1-0.1991)\\1-0.8009\\0.1991

The probability that on any given day the water supply is inadequate 0.1991

Xavier climbs 9 feet up into an apple tree. What integer represents the direction and how far he will climb to get back down to
natima [27]

Answer:

-9

Step-by-step explanation:

We are told in the question that:

Xavier climbs 9 feet up into an apple tree.

The direction symbol or sign for upwards movement = Positive (+) sign

If Xavier would climb back down , he will climb back down 9 feet as well

The direction symbol or sign for downwards movement = Negative (-) sign

Since we know the distance (or how far) he has to climb by downwards is also 9 feet, therefore, the integer that represents the direction and how far he will climb to get back down to the ground is -9

Factor out the highest common factor.<br><br>​
saw5 [17]

The highest common factor is found by multiplying all the factors which appear in both lists

a.(13-4b)(a+6)

13a-24b

13 and 24

so we have to factor this

13 =13×1

24=12×2=12 is 6×2=6 is 3×2=3 is 3×1=3×1

Therefore 1 and 1 get canceled

13×3=39

(a )39

like this we have to solve........
