If Malcolm selects two coins at random without replacement, what is the probability that he selects a nickel followed by a dime? Penny 8 Nickel 6 Dime 8 Quarter 7

Step-by-step explanation:

When Malcolm selects the 1st coin, the probability for it to be a nickel is 6/29.

When Malcolm selects the 2nd coin, the probability for it to be a dime is 8/28.

Hence the total probability is 6/29 * 8/28 = 14/203.

yes

yes yes yes

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
