Answer:

4x+1

Step-by-step explanation:

The way i got this was because sometimes on shapes there are 4 side and so you would multiply the number of sides then add some more to it.

Answer:

E(x)  = -$0.05263

E(y) = -$0.05263

V(x) = 0.9972

V(y) = 32.23

the expectations are the same, both will lose the same amount of money if they play for 38 times.

Though Variance is different. The girl betting on colors has little chance to gain  and lose but the boy betting on number has huge deviation

Step-by-step explanation:

Given that; you place a 1-dollar bet on the number 17 at Las Vegas and your friend places a 1-dollar bet on black.

Let x represent your winnings and y represent your friends winnings

we know that, There are 18 black slots, 18 red slots and two green slots (0 and 00) on a US roulette wheel.

so, the chances of getting black(red) = 18/38

now, E(y) = (18/38)$1 + (20/38)(-$1)

E(y) = -$0.05263

Now, bets made on the chart of the various numbers 1 to 36 and zero, Just put a chip down in the middle of the square with the number you select. If it comes up, it pays 35-to-1. It is called a straight up bet.

hence, the chance of getting selected number will be 1/38

so E(x) will be;

E(x) = (1/38)$35 + (37/38)(-$1)

E(x)  = -$0.05263

So, V(x) will be;

V(x) = [ 1 - (1/19)² ]

= 1 - 0.00277

V(x) = 0.9972

V(y) = { [ (35)² × (1/38) ] - (1/19)² }

= 32.2368 - 0.00277

V(y) = 32.23

Therefore, the expectations are the same, both will lose the same amount of money if they play for 38 times.

Though Variance is different. The girl betting on colors has little chance to gain  and lose but the boy betting on number has huge deviation.

Answer:

OB) The mode does not change

Answer:

36°, 42°, 72°, 102°, 108°

Step-by-step explanation:

Angles at a point = 360°

Therefore:

(3x - 6) + x + 3x + 2x + (x + 6) = 360°

Open parthenogenesis

3x - 6 + x + 3x + 2x + x + 6 = 360

Add like terms

10x = 360

Divide both sides by 10

x = 36

✔️Value of each angle:

Plug in the value of x in each expression

x = 36°

3x - 6 = 3(36) - 6 = 102°

3x = 3(36) = 108°

x + 6 = 36 + 6 = 42°

2x = 2(36) = 72°

Have a good day

Answer:

The polynomial -8x2 + 54x + 140 can be factored as (x + 2)(-8x + 70).

The factor (x + 2) represents the final price per hot dog after increasing it from the starting price of $2, where x is the number of $1 increases in price.

The factor (-8x + 70) represents the average number of hot dogs sold based on the price increase. For every $1 increase in price, the number of hot dogs sold declines by 8. So, if the price increases by x dollars, the number of hot dogs sold declines by 8x. Since the number of hot dogs sold without the price increase is 70, the number of hot dogs after a price increase is -8x + 70.

Answer:

  7

Step-by-step explanation:

The total length of ribbon is ...

  (10)(2.1 ft) = 21 ft

There are 3 feet in a yard, so the number of yards is ...

  (21 ft)×(1 yd)/(3 ft) = 7 yd

Answer: A(t) = (6.4 ft^2/min)*t

Step-by-step explanation:

We know that Emily paints at a constant rate, and she can paint 32 ft^2 in 5 minutes.

Then if we take the quotient of these two quantities, we will find the amount she can paint in one minute, this is:

32ft^2/5min = (32/5) ft^2/min = 6.4 ft^2/min.

Then if she paints for t minutes, the area that she can cover can be written as:

A(t) = (6.4 ft^2/min)*t

This is the linear equation we wanted to find.

Answer: [tex]0.416655[/tex]

Step-by-step explanation:

If random variable X has the binomial distribution B(n, p), then

[tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex]

, where  n= Total number of trials, x = number of successes , p= probability of success in each trial.

Given: The random variable R has the binomial distribution B (12,0.35).

n= 12, = 0.35

[tex]P(R>4)=1-P(R\leq4)\\\\=1-[P(R=0)+P(R=1)+P(R=3)+P(R=4)]\\\\\\=1-[^{12}C_0(0.35)^{0}(1-0.35)^{12}+^{12}C_1(0.35)^{1}(1-0.35)^{11}+^{12}C_2(0.35)^{2}(1-0.35)^{10}+^{12}C_3(0.35)^{3}(1-0.35)^{9}+^{12}C_4(0.35)^{4}(1-0.35)^{8}]\\\\= 1-[(1)(0.65)^{12}+(12)(0.35)(0.65)^{11}+\dfrac{12!}{2!10!}(0.35)^2(0.65)^{10}+\dfrac{12!}{9!3!}(0.35)^3(0.65)^{9}+\dfrac{12!}{8!4!}(0.35)^4(0.65)^{8}]\\\\=1-0.583345\\\\\approx0.416655[/tex]

Hence, P(R>4)=0.416655

Answer:

x = 2213

Step-by-step explanation:

We need to find the value of x, which is multiplied by 10. We know that 10x = 22130, so all we need to do is divide both sides by ten.

10x ÷ 10 = x

22130 ÷ 10 = 2213

Therefore, x = 2213

NOTE:

I'm not sure if you meant to type x10, because if so, that's an entirely new equation. If you just meant 10x, you can ignore this.

To solve this, you have to take the root of both sides and solve.

Exact Form:

x  =  10 √ 22130 ,  − 10 √ 22130  

Decimal Form:  x = 2.71955684 … ,  − 2.71955684 …

Answer:

x = 2213

Step-by-step explanation:

22130/10 = 2213

Answer:

The length of the rectangle (l) = 10 cm

The width of the rectangle (w) = 7 cm

Step-by-step explanation:

Step(i):-

Let 'x' be the length of the rectangle

Given that the width is 3 feet shorter than the length

The width of the rectangle = x -3

Area of the rectangle = length × width

Step(ii):-

Area of the rectangle = length × width

                                  = x ( x-3)

Given that the area of the rectangle = 70 square feet

                       x ( x-3) = 70

              ⇒   x² - 3x - 70 =0

              ⇒  x² - 10 x + 7 x - 70 =0

             ⇒  x (x -10) +7( x-10) =0

            ⇒ ( x+7) ( x-10) = 0

           ⇒  x =-7 and x=10

Final answer:-

we choose x=10

The length of the rectangle (l) = 10 cm

The width of the rectangle (w) = 7 cm

Answer:

10(5x - 6).

8(2m + 5).

9(3 - 5c)

Step-by-step explanation:

Given that

50x-60

16m+40

27-45c

The greatest common factor is a measure of the highest number present inside, or common to all the numbers that were listed. To take this one at a time, we have....

50x - 60. The highest number common to both of them is 10, and thus, we have

50x - 60 = 10(5x - 6), and this is the solved part.

16m + 40. The greatest number that's present inside both numbers is 8, and thus we have

16m + 40 = 8(2m + 5) and this is the solved part.

27 - 45c. The greatest common number is 9, and as a result, we have

27 - 45c = 9(3 - 5c), and this is the solution we were searching for

Answer:21660

Step-by-step explanation:

95*22800/100

Answer:

1st volume = 160

2nd volume = 160 + 54 = 214

3rd volume = 160 + 54 + 32 = 246

4th volume = x + 54 + 32 = 246

Step-by-step explanation:

Given that:

Number of volumes = 4

1st volume = x pages

2nd volume = 54 more = x + 54

3rd volume = 32 more = x + 54 + 32

4th volume = 32 more = x + 54 + 32

Total number of pages = 866

Hence,

1st + 2nd + 3rd + 4th = 866

x + x + 54 + x + 54 + 32 + x + 54 + 32 = 866

4x + 226 = 866

4x = 640

x = 160

1st volume = 160

2nd volume = 160 + 54 = 214

3rd volume = 160 + 54 + 32 = 246

4th volume = x + 54 + 32 = 246
