Answer:

y = 6/7

Step-by-step explanation:

The equation given is:

-3 = 7(y - 9/7)

To solve this, we will expand the bracket and afterwards, collect like terms:

-3 = (7*y) - (9/7 * 7)

-3 = 7y - 9

Collecting numeric terms to the left hand side:

-3 + 9 = 7y

=> 6 = 7y

=> y = 6/7

That is the solution.

Answer:

D. AP

Step-by-step explanation:

A hypotenuse is a side of a triangle, so you can get rid of answers A and B as those are angles.

A hypotenuse is the longest side in a right triangle. You can see just by looking at the picture that AP is much longer than ZP

Answer:

Variance Σ i=1 (1 - Pi) /Pi^2

Expected value= π(1/1 + 1/2 .......... 1/n) = π.Hn

Step-by-step explanation:

From the information given, we can get

E(T) = E(t1) + E(t2) ......... +E(tn)

1/P1 + 1/P2.......... 1/Pn

-π/r + π/ r-1 +........... π/1

π(1/1 + 1/2 .......... 1/n)

To find the variance,

Variance= var (x1 + x2......... +xr)

E i=1 var (Xi)

Where,

x1, x2, x3 ........... are all independent of each other.

In case of xi : var (xi) = E(xi^2) - E(xi^2)

Probability of the ith term of coupon that would be observed

Pi = (n - i - 1)/n

Therefore,

i-1 coupons out of a total of n coupons.

To calculate Exi, probability Pi

The expected number of coupons required should be = 1

In probability, 1 - Pi expected number of coupons required E (Xi +1)

E(Xi) = Pi + (1- Pi) E(xi + 1)

E(Xi) = 1/Pi

Due to the above,

E(Xi)^2= Pi + (1- Pi) E(xi + 1)^2

E(Xi)^2= Pi + (1- Pi) E(xi^2 + 1 + 2xi)

E(Xi)^2= 2/Pi^2 - 1/Pi

Var (Xi) = 2/Pi^2 - 1/Pi - 1/Pi^2

= (1 - Pi) /Pi^2

Variance Σ i=1 (1 - Pi) /Pi^2

Sara Blake's grandmother gave her $3000.00 to save for college. She put it in a savings account that earns 6% interest per year.
zubka84 [21]
I assume you are looking for the total. The total amount in the account will be $4,781.54 if the interest is compounded annually.

If she is earning 6% interest, the balance in her account will be multiplied by 1.06 each year.

You can evaluate the following expression to find the total.
3000(1.06)^8 = 4781.54

What is the equation in slope-intercept form for the line that passes
igomit [66]

Answer:

y = 6x + 9

Step-by-step explanation:

Δy =-3-3 = -6

Δx =-2-(-1) = -1

Slope = Δy/Δx = 6

Point-slope equation for line of slope 6 that passes through (-1,3):

y-3 = 6(x+1)

Rearrange to solve for y:

y = 6x + 9
