For day after tomorrow - (1)/(10)

According to question :

Probability of win tomorrow, then win the day after tomorrow is given by multiple of probability of tomorrow and day after tomorrow.

i.e,

\text{P(win tomorrow, then win the day after tomorrow)}=\text{P(tomorrow)}* \text{P(day after tomorrow)}

\text{P(win tomorrow, then win the day after tomorrow)}=(1)/(8)* (1)/(10)

\text{P(win tomorrow, then win the day after tomorrow)}=(1)/(80)
1/80 because 1/8 times 1/10 equals 1/89

a path across a park is represented by the equation y=-2x+5. A new path will be built perpendicular to this path. the two paths cross at (-2,9). I identify the equation that represents the new path. ​

Answers

Answer:

y = ½x + 10

Step-by-step explanation:

Perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE RateofChanges[Slopes], so you need to have a slope of ½, like in the work shown below:

9 = ½[-2] + b

-1

10 = b

Which of the following represents 645?A. 6 hundreds + 5 ones
B. 3 hundreds + 34 tens + 5 ones
C. 5 hundreds + 4 tens + 5 ones
D. 6 hundreds + 2 tens + 15 ones

Answers

The answer would be D because you have 6 hundreds and the 2 tens and 15 ones because if you took out ten from the ones then you would get 3 tens and 5 ones. The hope I didn't confuse you
its D. because 6 = 600 so 2 tens + 600 = 620 so 15 plus all of the above is 645 :D hope this helped

The Quadratic Formula, x equals negative b plus or minus the square root of b squared minus 4 times a times c, all over 2 times a, was used to solve the equation 3x2 + 4x − 2 = 0. Fill in the missing denominator of the solution. negative 2 plus or minus the square root of 10, all over blank A.−4
B.2
C.3
D.6

Answers

By using a quadratic equation the missing denominator of the solution is 4 plus or minus the square root of 2, all over is (B).2

What is a Quadratic Equation?

For a Quadratic Equation $a x^(2)+b x+c=0$

By Formula Method we get

$x=\frac{-b \pm \sqrt{b^(2)-4 a c}}{2 a}$

So we have a Quadratic Equation that is $2 x^(2)-8 x+7=0$

On Comparing we get,

a = 2

b = -8

c = 7

By substituting a, b, and c values we get

&x=\frac{-(-8) \pm \sqrt{(-8)^(2)-4(2)(7)}}{2(2)} \n

&x=(8 \pm √(64-56))/(4) \n

&x=(8 \pm √(8))/(4) \n

&x=(8 \pm 2 √(2))/(4) \n

&x=2\left((4 \pm √(2))/(4)\right) \n

&x=(4 \pm √(2))/(2)

Therefore, by using a quadratic equation the missing denominator of the solution 4 plus or minus the square root of 2, all over is (B).2

Hence the correct answer is option B.2

Answer:

C. 3

Step-by-step explanation:

3x² + 4x - 2 = 0

[-4 +- sqrt(4² - 4(3)(-2))]/(2×3)

[-4 +- sqrt(40)]/6

[-4 +- 2sqrt(10)]/6

Simplifying, we get:

[-2 +- sqrt(10)]/3
