Answer:

\frac{ae}{be}  =  \frac{ce}{de}  =  \frac{bc - be}{ad - ae}  \\  \\  =  >  \frac{8}{3}  =  \frac{15 - 3}{ad - 8}   \\ \\   <  =  >  \frac{8}{3}  =  \frac{12}{ad - 8}   \\  \\  =  > ad - 8 =  \frac{12 \times 3}{8}  = 4.5 \\  \\  <  =  > ad = 4.5 + 8 = 12.5 \\  \\  =  > r = 12.5 \div 2 = 6.25

Answer:

8×ED=3×15

ED=45/8

the radius is the half of the diameter

so its 45/16

Sherry has a standard deck of cards. The deck has 52 total cards and contains 4 suits: hearts, clubs, diamonds, and spades. Each
tatyana61 [14]

Answer:

c) Events A and B are independent events.

The outcomes of events A and B are dependent on each other.

P(A and B)=P(A)•P(B)

Step-by-step explanation:

Given:

Total number, n = 52

Each suit contains 13 cards: 2 to 10, a jack, a queen, a king, and an ace.

Since there are 4 suits, it means the number of each card is four.

P(A) = event of picking a king

P(B) = event of picking a 3

Therefore the probability of picking a king = P(A) = \frac{4}{52}

Probability of picking a 3 = P(B) = \frac{4}{52}

Since only a card is picked, the probability a king is picked after picking a 3 is 0.

i.e P(A|B) = 0 ≠ P(A) = \frac{4}{52}

option A is wrong

The probability a 3 is picked after picking a king is 0.

i.e P(B | A) = 0 ≠ P(B) = \frac{4}{52}

option B is wrong

Events A and B are independent events.

The outcomes of events A and B are dependent on each other.

P(A and B)=P(A)•P(B)

Option C is correct.

Plutonium-240 decays according to the function Q(t)=Q(subscripto)e^(-kt) where Q represents the quantity remaining after t years
svetoff [14.1K]
<span>The answer is 9,990 years. Using the exponential decay question, we can figure out how long it will take Plutonium-240 to decay from 27 grams to 9 grams. Setting the equation up looks like this, 9 = 27 e^ (-0.00011 t). From this you get, 0.333333 = e ^(-0.00011 t). Next, you simplify by dividing both sides by the natural log, -1.0986 = -0.00011 t. Finally, you solve by dividing both sides by -0.00011, giving 9,987 years for t, rounded up to 9,990 years.</span>
