Answer:

The expected value can be calculated as:

Es = x₁*p₁ + x₂*p2 + .....

where xₙ is the event (the amount of money that you win or lose, and pₙ is the probability for the event)

for example, in a 10 side dice, the probability of obtaining a specific number is 1/10.

we have a d10 i guess (a dice with 10 sides, 1 to 10)

if you roll from 1 to 7, nothing happens.

If you roll an 8, you lose $1500

if you roll a 9, you lose $75

if you roll a 10, you lose $2000 (and the game)

the expected value is,

Es = 1/10*(7*0 - 1*$1500 - 1*$75 - 1*$2000) = -$357

in the second case, you start paying $500.

if you roll a 7, you must pay $1000, if else, nothing happens.

Then the expected value is

Es = -$500 - 1/10*(-1*$1000 + 9*$0) = -$600

So the expected value is smaller in this case, so the deal is not fair

Answer:

<CAB and <DAE are vertical angles

<EAB and <CAD are vertical angles

Step-by-step explanation:

this is because they are formed by the prolongation of the sides of the other angles and are opposite to them on the other side of the vertex.

Options B and D are correct. The vertical angles are ∠CAD and ∠BAE AND ∠EAB and ∠CAD.

Vertical angles are angles that are opposite to each other in line geometry. The size of the angles must be the same.

According to the diagram shown, we can see that ∠CAD and ∠BAE are opposite to each other with similar measures.

Hence the vertical angles are ∠CAD and ∠BAE AND ∠EAB and ∠CAD.

Step-by-step explanation:

find out what the new given denominator (bottom number)/ numerator (top number) and divide the missing denominator/numerator by the number founded for the given numerator. in example: 3 people/9 pizzas. we are given the denominator of 3 pizzas and 9 divided by 3 is 3. so if the denominator is is dived by 3 the numerator must be divided by 3 as well. vice versa (same thing) if it was the numerator was given.

Answer:

Step-by-step explanation:

From the diagram, it can be seen that TR is parallel to RV. This means that TR = RV. Given TR = 17 and RV = 3x+2

3x+2 = 17

3x = 17-2

3x = 15

x = 5

RV = 3(5)+2 = 17

QV = 4x+1 = 4(5)+1

QV = 21

Using Pythagoras theorem on ΔQRV to get RQ

QV² = QR²+RV²

21² = QR²+17²

QR² = 21²-17²

QR = 12.33

Using Pythagoras theorem on ΔQRT to get QT

From ΔQRT,

QT² = QR²+TR²

QT² = 12.33²+17²

QR² = 152.0289+289

QT² = 441.0289

QT =21

Since TS = 9(5)-4 = 41

Using Pythagoras theorem on ΔTRS

From ΔTRS,

TS² = RS²+TR²

41² = RS²+17²

RS² = 41²-17²

RS² = 1392

RS = 37.31

Similarly Using Pythagoras theorem on ΔRSV

From ΔRSV,

SV² = RV²+RS²

SV² = 17²+37.31²

SV² = 1681.0361

SV = 41

Answer:

SV=41

QT=21

Hi!

The negative signs cancel out iin the equation to make a positive 7.

The 4 is already positive.

So that makes it 4 + 7!

Or 7 +4!

Answer:

343

Step-by-step explanation:

There are quarters(25¢), loonies ($1), and toonies ($2)

And total number of coins is 9

If loonies ($1), and toonies ($2) are one, then quarters(25¢) is 7

If quarters(25¢), and toonies ($2) are one, then loonies ($1)is 7

If loonies ($1), and quarters(25¢) are one, then toonies ($2) is 7

So possible number number of combination for an item that cost between $10 and $12 is

= 1^3 * 1^3 * 7^3

= 343

hope this helps, stay safe :)

The number of different combinations of coins could Teo use to pay for an item that costs between $10 and $12 is 17.

Combinations are defined as the arrangement of objects or numbers in a way such that the order of the arrangement does not matter.

Given that,

Teo has a combination of quarters, loonies, and toonies in his pocket.

Total number of coins = 9

1 quarter = $0.75

1 loonie = $1

1 toonie = $2

If he uses fewer toonies than loonies,

Total number of combinations of 9 coins = 1³ × 1³ × 7³ = 343

We need the number of combinations in between $10 and $12.

We can form the following combinations.

(2 × $1) + $2 gives $4. Remaining can be 8, 9 and 10 quarter coins.

(3 × $1) + (2 × $2) gives $7. Remaining can be 4, 5 and 6 quarter coins.

(3 × $1) + (1 × $2) gives $5. Remaining can be 7, 8 and 9 quarter coins.

(4 × $1) + (3 × $2) gives $10. Remaining can be 1 or 2 quarter coins.

(4 × $1) + (2 × $2) gives $8. Remaining can be 3, 4 and 5 quarter coins.

(4 × $1) + (1 × $2) gives $6. Remaining can be 6, 7 and 8 quarter coins.

Total number of combinations = 3 + 3 + 3 + 2 + 3 + 3 = 17

Hence the total number of combinations are 17.

Answer:

t can equal 7 or -7

Step-by-step explanation:

Answer:

t=7 or t=-7

Step-by-step explanation:

To solve for t, we need to get t alone. To do this, perform the opposite of what is being done to the equation. Keep in mind, everything must be performed to both sides.

t^2=49

t is being squared. The opposite of squared is the square root. Take the square root of both sides.

√t^2=√49

t=√49

t=±7

So, t is equal to 7 or -7
