A company can make 60 computers for $58,200, and can make 90 computers for $85,200. write an equation that represents the cost,
Eddi Din [679]
(60,58200) , (90,85200)
slope = (85200 - 58200) / (90 - 60) = 27,000/30 = 900

y = mx + b
slope(m) = 900
(60,58200)...x = 60 and y = 58200
sub and find b, the y int
58200 = 900(60) + b
58200 = 54000 + b
58200 - 54000 = b
4200 = b

ur equation is : C(x)  = 900x + 4200 <== ur equation

Suppose the chance of winning a game is 1/50. If you play the game 50 times independently, is it certain that you will win? If n
arlik [135]

We are given chance of winning a game is 1/50.

In decimal form 1/50 could be written as 0.02.

So, for each game, the chance of winning is 0.02.

Therefore, chance of loss would be = 1 -(0.02) = 0.98.

Chance of loss of 50 independent games = 0.98*0.98*0.98*0.98...... upto 50 times, that is (0.98)^50.

The chance of winning at least once = 1 - (0.98)^50.

We got (0.98)^50 = 0.36417

Therefore, 1 - (0.98)^50 = 1 - 0.36417.

We get 0.63583.

Therefore, correct option is c. 0.6358.

The average cost for a gallon of gasoline increased from $2.56 one year to $3.18 the next year. What is the percent of increase,
frez [133]
%change=100(final-initial)/initial

In this case:

%change=100(3.18-2.56)/2.56

%change=100(0.62)/2.56

%change=62/2.56

%change=775/32%

%change=24.21875%

%change≈24%  (to nearest whole percent)

The length sides of the two legs are the same, because is a 45\°-90\°-45\° triangle

The third side is the hypotenuse and the hypotenuse is always greater that the legs
