What is the solution

ladessa [460]

Answer:

No solutions or ∅

Step-by-step explanation:

Do the algebra:

$-\frac{1}{3}+\frac{2}{3}m=\frac2 3 m - \frac 2 3 \\\\\frac 2 3 m = \frac 2 3 m - \frac 2 3\\\\0=-\frac 2 3$

Since 0 ≠ -2/3, this equation has no solutions.

Hope this helped :)

Given the coordinates S(-3,6) and T(4, -8). Find the equation of the line that passes through the two points and write the equat

baherus [9]

Answer:

m=slope

y= intercept

m=y2-y1 /x2-x1 -8 - 6= -14

4- -3 = 7

-14/7 a 2 is your slope

y=2x=b

Now we find for X

choose a y from one of your points : lets use 6 Plug 6 in for y s(-3,6)

y=2x+b

6=2(-3) +b

now solve for b

6= -6 + b

now add 6 to both sides to get b alone

6+6 =6+-6 +b

12=b

now write you equation out y=2x =12

Step-by-step explanation:

hope that helps

Cameron is playing 9holes of golf. he needs to score a total of at most 15 over par on the last four holes to beat his best golf

adelina 88 [10]

A. 5-1+6-1=9

b. His score is over par by 9 because 5-1+6-1=9.

c. Yes he beat it because he is only 9 over par.

BONUS: In the kite shown below, the perimeter of the kite is 16 units.

8090 [49]

Answer:

6(2) -2(-5) Substitute the values given into the expression and multiply. 12+10 ... 1. 2x-(3-4y), when x = 5 and y=-3. 215)-(3-4(-3)). 10-(3+12). 10-15. 2. ... + (3 - 3 x + 1 +. 6-3x = 4x + 4. Bebetto. 2=7x -. - 4-2=34+12. - ý 2=2y+12. + ... y = 2x-1. Simplify. Subtract 2x from each side. Multiply both sides by -1. 2+3 m.

Step-by-step explanation:

If 2x + y = 7 and x + 2y = 5, then (x + y)/3 = (A) 1 (B) 4/3 (C) 17/5 (D) ... Divide both sides by 3 to get: x + y = 4 ... 2*(x+2y = 5) equals 2x+4y=10 ... or subtracting one from the other and it likely happens 90% times that ...

consider a sequence of independent tosses of a biased coin at times k=0,1,2,…,n. On each toss, the probability of Heads is p, an

omeli [17]

Answer:

1. p*(1-p)

2. n*p*(1-p)

3. p*(1-p)

4. 0

5. p^2*(1-p)^2

6. 57/64

Step-by-step explanation:

1. Let Ik denote the reward (possibly 0) given at time k, for k∈{1,2,…,n}. Find E[Ik].

E[Ik]= p*(1-p)

2. Using the answer to part 1, find E[R].

E[R]= n*p*(1-p)

The variance calculation is more involved because the random variables I1,I2,…,In are not independent. We begin by computing the following values.

3. If k∈{1,2,…,n}, then

E[I2k]= p*(1-p)

4. If k∈{1,2,…,n−1}, then

E[IkIk+1]= 0

5. If k≥1, ℓ≥2, and k+ℓ≤n, then

E[IkIk+ℓ]= p^2*(1-p)^2

6. Using the results above, calculate the numerical value of var(R) assuming that p=3/4, n=10.

var(R)= 57/64
