 <span>x - 8y = 46.5 
x - 13y = 39.0 

subtract the equations to solve for y 

5 y = 46.5 - 39 
y = 1.5 so he saves 1.5 seconds per step he runs. 

sub in y to solve for x 
x - 8 (1.5) = 46.5 
x - 12 = 46.5

Which solution to the equation 3/2g+8 g+2/g^2-16 is extraneous? A. g = –4 B. g = –4 and g = 16
ollegr [7]

im assuming the equation is:-

3 / (2g + 8) = (g + 2) / (g^2 - 16)

3(g^2 - 16) = (2g + 8)(g + 2)

3g^2 - 48 = 2g^2 + 4g + 8g + 16

Answer is A  x = -4

3g^2 - 2g^2 - 12g - 64 = 0

g^2 - 12g - 64 = 0

( g + 4)(g - 16) = 0

g = - 4, 16.

Test these solutions:-

g = -4  

left side = 3/0    which is indeterminate

right side = -2/0  indeterminate

So x = -4 is extraneous.

x = 16:- LHS = 0.075  RHS =  0.075  so x = 16 is a root.

The probability that the San Jose Sharks will win any given game is 0.3694 based on a 13-year win history of 382 wins out of 1,0
kobusy [5.1K]

Answer:

4.43

Step-by-step explanation:

Given :The probability that the San Jose Sharks will win any given game is 0.3694 based on a 13-year win history of 382 wins out of 1,034 games played

To Find : What is the expected number of wins for the that upcoming month?

Solution :

The probability that the San Jose Sharks will win is 0.3694

Let X = number of games won

Total no. of games = 12

We are supposed to find the expected number of wins for the that upcoming month

So, expected number of wins = E(X)=XP(X)=12 \times 0.3694 =4.43

Hence the expected number of wins for the that upcoming month is 4.43
