Answer:

w = 4

Step-by-step explanation:

you would do this by re-arranging the equation

6 = 5w-10-w (move w to the other side)

6 = 4w-10 (because 5w-w = 4w)

6+10=4w (move 10 to the other side)

16 = 4w (add 6 and 10)

4 = w (divide both sides by 4)

Christy draws 3 cards from the deck one at a time without replacement. What is the probability of selecting the cards in the ord

Inga [223]

Start with a deck of 52 cards. Draw 1 card. Probability of drawing a diamond first:

$\dfrac{\binom{13}1}{\binom{52}1}$

Now draw another single card from the deck, which now contains 51 cards. Probability of drawing a spade:

$\dfrac{\binom{13}1}{\binom{51}1}$

Draw 1 last card. The deck has 50 cards left, and 12 of these are diamonds. Probability of drawing a diamond:

$\dfrac{\binom{12}1}{\binom{50}1}$

So the probability of drawing a diamond, then a spade, then another diamond is

$\dfrac{\binom{13}1}{\binom{52}1}\cdot\dfrac{\binom{13}1}{\binom{51}1}\cdot\dfrac{\binom{12}1}{\binom{50}1}=\dfrac{13}{850}$

I thought the answer was 15.48 but I don’t know the answer

Given:

Total tips = $ 77.40

Ratio of tips sharing = 2 : 3 : 4

To find:

How much more does Brian get over Paul

Solution:

Let 2x, 3x and 4x be the cost of tips got by Paul, Colin and Brian.

Total cost of tips =$ 77.40

2x + 3x + 4x = 77.40

9x = 77.40

Divide by 9 on both sides.

$$\frac{9x}{9}=\frac{77.40}{9}$

x = 8.6

Brian gets = 4(8.6) = $34.4

Paul gets = 2(8.6) = $17.2

Difference = 34.4 - 17.2

= 17.2

Therefore Brian gets $17.2 more than Paul.

<h3>✽ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ✽</h3>

➷ Joni should have multiplied by 1000 because 1 dekagram is equal to 1000 centigrams.

How do you know it is positive or negative in exponents.

hammer [34]

When using exponents there will be a negative sign before the exponent. If the exponent is positive it will not have any sign it will just be the number
