Answer:

111

Step-by-step explanation:

360 - 65 - 106 - 78 = 111

Answer:

The correct option is -

Yes, because the Expected value is 1 and not negative which would imply that there is a chance of winning.

Step-by-step explanation:

Given - A bag contains 10 blue marbles, 3 yellow marbles, and 12 orange marbles. If a blue marble is drawn you win $10. If a yellow marble is drawn you win $15. if an orange marble is drawn you lose $10. it cost $1 to play.

To find - Should you play the game?

Formula used -

Expected value , E[x] = ∑x p(x)

where p(x) is the probability.

Proof -

Given that,

Total blue marbles in a bag = 10

Total yellow marbles in a bag = 3

Total orange marbles in a bag = 12

So,

Total number of marbles in a bag = 10 + 3 + 12 = 25

Now,

Probability of getting blue marble = [tex]\frac{10}{25}[/tex]

Probability of getting yellow marble = [tex]\frac{3}{25}[/tex]

Probability of getting orange marble = [tex]\frac{12}{25}[/tex]

So,

Expected value , E[x] = ∑x p(x)

                                   = (10)( [tex]\frac{10}{25}[/tex]) + (15)([tex]\frac{3}{25}[/tex]) + (-10)([tex]\frac{12}{25}[/tex])

                                   = [tex]\frac{100}{25} + \frac{45}{25} - \frac{120}{25}[/tex]

                                   = [tex]\frac{100 + 45 - 120}{25}[/tex]

                                   = [tex]\frac{25}{25}[/tex]

                                   = 1

So,

Expected value = 1

So,

The correct option is -

Yes, because the Expected value is 1 and not negative which would imply that there is a chance of winning.

x²+4x+4=0

(x+2)(x+2)=0

x= -2

f(g(x))=0

f(6x+4)=0

f(0)=0

x=-4/6

i did it in to step because i didnt understand what you mean we you write (f+g)(x)

but probably the first answer is the correct one

Answer:

x = - 2

Step-by-step explanation:

(f + g)(x)

= f(x) + g(x)

= x² - 2x + 6x + 4

= x² + 4x + 4

Then

x² + 4x + 4 = 0 ← in standard form

(x + 2)² = 0 ← in factored form

x + 2 = 0

x = - 2

Answer:

The longest length is 30 cm

Step-by-step explanation:

Mathematically, the perimeter of a triangle is simply the sum of the lengths of its three sides

So, what we have to do here is divide the perimeter in the given ratio to get the side lengths

since 5 is the biggest of the numbers in the ratio, it represents the largest length value

so we have this as;

(3 + 4 + 5) = 12

So that would be;

5/12 * 72

= 5 * 6 = 30

Answer:

He can save $76.8 by buying them at the Fitness Depot.

Step-by-step explanation:

If the coach buys a dozen footballs, it means that he buys 12 and first, you need to determine the cost of purchasing the 12 footballs at each store by multiplying the amount of footballs for the price at each store.

-Sports R' Us: $27.99*12=$335.88

-Fitness Depot: $21.59*12=$259.08

Then, you have to find the difference between the total cost at both places:

$335.88-$259.08=$76.8

According to this, the answer is that he can save $76.8 by buying them at the Fitness Depot.

Answer:

The child has 6 dimes and 5 quarters.

Step-by-step explanation:

Let q and d represent the number of quarters and of dimes respectively.

Then q + d = 11 (Equation A), and ($0.25/quarter)q + ($0.10/dime)d = $1.85 (Equation B).

Multiply the 2nd equation by 100 to remove the decimal fractions:

25q + 10d = 185 (Equation C)

Now multiply the 1st equation by -10 to obtain -10q - 10d = -110 (Equation D), and combine this result with Equation C:

-10q - 10d = -110

25q + 10d = 185  

--------------------------

15q = 75, and so q = 75/15 = 5.

According to Equation A, q + d = 11.  Replacing q with 5, we get:

5 + d = 11, and so d = 6.  

The child has 6 dimes and 5 quarters.

Answer: The amount of money in quarters is $1.75

Step-by-step explanation: There are 7 quarters. 25c+25c+25c+25c+25c+25c+25c=1.75

Is this true or uhhhh id,k tbh

Thanks for the free point.s anyways

Answer:

y=4.47 and x=√10

Step-by-step explanation:

180°-45°-90°=45°

√10/(sin 45°)=y/(sin 90)

y=4.47

√10/(sin 45°)=x/(sin45)

x=√10

Answer:

7

Step-by-step explanation:

Expressing Both equations in the slope intercept format : y = mx + c

Function A :

y = 8x + 3

Where, slope = 8 ; intercept = 3

Function B:

y = x - 4

Note ;

Rate of change = slope

Rate of change or slope of function A = 8

Slope of function B = 1

Difference = 8 - 1 = 7

Answer:

5.25 inches after 5 wks

7 inches after 12 wks

Step-by-step explanation:

after 5 weeks:  y = .25(5) + 4 which is 5.25 inches

after 12 weeks:  y = .25(12) + 4 which is 7 inches

Answer:

6x² + 8x + 2

Step-by-step explanation:

(-x² + 2x - 3) + (7x² + 6x + 5 ) = ?

-x² + 2x - 3 + 7x² + 6x + 5 = ?

-x² + 7x² + 2x + 6x - 3 + 5 = ?

? = 6x² + 8x +2

have a nice day :)

Answer:

5/12 hours

Step-by-step explanation:

Honon = 3 1/4 hours

Sequoia = 2 5/6 hours

How much more time did Honon spend on homework than Sequoia

= number of hours Honon spent - number of hours Sequoia spent

= 3 1/4 hours - 2 5/6 hours

= 13/4 - 17/6

= (39-34) /12

= 5/12 hours

Answer:

[tex]141^{\circ}[/tex]

Step-by-step explanation:

The quadrilateral in the image is a cyclic quadrilateral, because it is circumscribed by a circle. In all cyclic quadrilaterals, each pair of opposite sides are supplementary (add up to 180 degrees). Therefore, we have the following equation:

[tex]m\angle T+39=180,\\m\angle T=\boxed{141^{\circ}}[/tex]

Answer:

The correct selections are A and B.

Step-by-step explanation:

The picture depicted above can be represented as [tex]5w+4=99[/tex], since 5 times something plus 4 is the same as 99. In choice a, Andre babysat 5 times and earned the same amount of money each time, so you could represent that by [tex]5w[/tex]. Since he received an extra $4 and earned a total of 99 dollars, the first choice is correct. In choice B, the family of 5 paid the same amount for each ticket, which can be represented by [tex]5w[/tex]. Since they paid $4 for parking and paid a total of $99, choice B can also be represented by the picture, which means it's correct.
