The ordered pairs for :

(a) Y = 9-4x are (-2,17), (5,-11) ,(2/3,19/3) and (0.75,6).

(b) Y = 1/x are (-2.-1/2), (5,1/5), (2/3,3/2) and (0.75,1.33)

We are given two functions for which corresponding y-values need to be found for the given x-values so that ordered pairs of the form (x, y) can be formed.

Consider the function Y = 9-4x.

When x = -2, y = 9-(4 x -2) = 17

When x = 5, y = 9-(4 x 5) = -11

When x = 2/3, y = 9-(4 x 2/3) = 9-(8/3) = 19/3

When x = 0.75, y = 9-(4 x 0.75) = 6

So the ordered pairs are: (-2,17), (5,-11) ,(2/3,19/3) and (0.75,6).

Consider the function Y = 1/x

When x = -2, y = 1/-2 = -1/2

When x = 5, y = 1/5

When x = 2/3, y = 1/(2/3) = 3/2

When x = 0.75, y = 1/0.75 = 1.33

So the ordered pairs are: (-2.-1/2), (5,1/5), (2/3,3/2) and (0.75,1.33)

You watch a roulette wheel spin 270 consecutive times and the ball lands on a red slot each time. what is the probability that t

Rus_ich [418]

18/37 if you're in Europe, 9/19 if you're in America, assuming the wheel isn't rigged. If the roulette wheel is a fair wheel, the odds on any given spin of the wheel is unaffected by any previous spins of the wheel. So no matter how many times the wheel has consecutively come up red, the next spin can still come up red, black, or green based upon the number of each color is present on the wheel. The difference between the odds for Europe vs America has to do with a quirk about roulette. In Europe, the roulette wheel has 37 slots, 18 red, 18 black, and 1 green. In America, the roulette wheel has 38 slots, 18 red, 18 black, and 2 green. Although in this case, I'd be wary about assuming that the wheel isn't rigged. The odds of 270 consecutive red on a fair wheel is only 1 in 3.09663x10^84 in Europe, or 1 in 4.14949x10^87 in America.

On your tenth birthday, you received 500 which you invested at 9.5% interest, compounded annually. your investment is worth $250

igomit [66]

Compounded once a year: A=P(1+r)^t
2500=500(1+0.095)^t
1.095^t=5
because the unknown number is an exponent, use log to find the unknown:
log(1.095^t)=log5
tlog1.095=log5
t=log5/log1.095
use your calculator, t=17.734
so this person is about 28 years old.

For every quarter he spends, Reggie receives 50 food pebbles to feed the fish. Reggie has thrown 350 food pebbles into the fish

deff fn [24]

Answer:

7 quarters are spent for throwing 350 food pebbles in pond.

Step-by-step explanation:

Given:

Reggie receives 50 food pebbles for every quarter he spends.

Number of food pebbles he has = 350

Let the number of quarters spent for 350 pebbles be 'x'.

Now, using proportion and cross multiplication method, we can find 'x'.

1 quarter is equivalent to 50 pebbles thrown in pond.

So, 'x' quarters is equivalent to 350 pebbles thrown in pond.

$\frac{1}{50}=\frac{x}{350}\\\\Cross\ multiplying\\\\50x=350\\\\x=\frac{350}{50}\\\\x=7$

So, 7 quarters are spent for throwing 350 food pebbles in pond.
