Jessie sorted the coins in her bank. She made 7 stacks of 6 dimes and 8 stacks of 5 nickels. She then found 1 dime and 1 nickel.

ANEK [815]

Hello!

So, Jessie made 7 stacks of dimes and 8 stacks of nickels.

Each stack of dimes has 6 dimes.

Each stack of nickels has 5 nickels. Multiply:

6 × 7 = 42

8 × 5 = 40

Then she finds another dime and another nickel.

42 + 1 = 43

40 + 1 = 41

43 + 41 = 84

ANSWER:

Jessie has 43 dimes, 41 nickels, and 84 coins in all.

A pair of fair dice is cast. what is the probabiliy that the sum of the numbers falling uppermost is 9, given that at least one

WITCHER [35]

If a pair of fair dice is cast, the probability that the sum of the numbers falling uppermost is 9, given that at least one of the numbers falling uppermost is a 3 is given by:

$\frac{P(sum\, of\, 9\, \cup\,3)}{P(3)}$

The number of outcomes of sum of 9 where at last one is 3 is (3, 6) and (6, 3) = 2.

The number of outcomes of last one of the numbers falling uppermost is a 3 is (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6), (1, 3), (2, 3), (4, 3), (5, 3) and (6, 3) = 11.

Therefore, the probabiliy that the sum of the numbers falling uppermost is 9, given that at least one of the numbers falling uppermost is a 3 is 2 / 11.

Find the area of the region enclosed by x(t)=t^2-2t, y(t)=sqrt(t), and the y-axis. ...?

zaharov [31]

First find the the value of t where the curve intersects the Y-axis. This is when x = 0.

x = t^2 - 2t = 0 = t(t - 2)

So t= 0 and t = 2

dA = (0 - x)*dy .... Since the curve has negative x in this region

y = SQRT(t) and dy = [(1/2)/SQRT(t)]dt

dA = [2t - t^2][(1/2)/SQRT(t)]dt

dA = [t^(1/2) - (1/2)t^(3/2)]dt

Integrate to get: A = (2/3)t^(3/2) - (1/5)t^(5/2)

Now evaluate from t= 0 to t = 2.

Area = [(2/3)2^(3/2) - (1/5)2^(5/2)] - [0]

Area = SQRT(2)[4/3 - 4/5]

Area = SQRT(2)[8/15) = 0.754
