The sum of 8n^2-3n+10 and -3n^2 -6n-7 is

EastWind [94]

8n^2-3n+10 + -3n^2-6n-7

8n^2 + -3n^2 = 5n^2

-3n + -6n = -9n

10 + -7 = 3

Put them all together and you get 5n^2-9n+3

I tried to space them out so that it makes more sense.

Step-by-step explanation:

Q is abt a geometric series given by the eqn: an = a1*r^(n-1)

given a1 = 40000, r = 0.1

an = 40000*(0.1)^(n-1)

a8 = 40000*(0.1)^(8-1)

Gala2k [10]

Answer: c) 0.75

Step-by-step explanation:

Given : The probability of choosing a black marble is P(Black)= 0.36.

The probability of choosing a black and then a white marble is P( Black and white) = 0.27.

Then by conditional probability ,

The probability of the second marble being white if the first marble chosen is black = $P(\text{white }|\text{Black})=\dfrac{\text{P( Black and white)}}{\text{P(Black}}$

$=\dfrac{0.27}{0.36}=\dfrac{27}{36}=0.75$

Therefore , the probability of the second marble being white if the first marble chosen is black = 0.75
