10 cards would have 5 even cards.

First pick would be 5/10 = 1/2 probability of getting an even card.

Without replacing there are 9 cards left with 4 even ones. The probability of picking an even card would be 4/9

The probability of both happening would be Found by multiplying the two probability’s together:

1/2 x 4/9 = 4/18 = 2/9

DiKsa [7]

Answer:

Net Proceeds = Selling Price - Total Cost Price

a. Samantha

Total Cost Price;

Bought shares for d dollars and paid 2% commission = d + (d * 2%) = 1.02d

Selling Price;

Sold stock for s dollars and paid flat fee of $11 = s - 11

Net Proceeds = (s - 11) - 1.02d

b. Alex

Total Cost Price;

Bought x dollars worth and paid 1% commission = x + (x * 1%) = 1.01 * x = 1.01x

Selling Price;

Value falls to y and Alex pays 1.25% when he sells = y - (y * 1.25%) = y - 0.0125y = 0.9875y

Net Proceeds = 0.9875y - 1.01x

The cost of renting a car for a day is $0.70 per mile plus a $20 flat fee
Andreyy89

Answer:

a) y = .70x + 20

-To find this, use the rate as x since it will change based on the number of miles. Since 20 is a flat fee, it can be added at the end as a constant.

b) This graph forms a straight line.

-This is because the answer in a is a linear equation.

c) The slope is .70 and the y-intercept is 20.

-For this one, the y-intercept is always the constant at the end of the equation and the slope is the coefficient of x.
