Area for square = s² = 196x¹²y¹⁰z⁶

s = √(196x¹²y¹⁰z⁶)

s = 14x⁶y⁵z³

Perimeter = 4*s = 4*(14x⁶y⁵z³) = 56x⁶y⁵z³

In a certain lottery game, 34 numbers are randomly mixed and 7 are selected. A person must pick all 7 numbers to win. Order is n

777dan777 [17]

Answer:

p(win)=0.00094

Step-by-step explanation:

-This is a factorial/combination question.

-The probability is calculated using the formula:

$p=\frac{x!}{_nC_x}\\\\$

Where:

$x$ is the number of successful picks

$n$ is the total number of picks

Therefore, we calculate the probability as follows;

$Pp=\frac{x!}{_nC_x}\\\\=\frac{7!}{_{34}C_7}\\\\=0.00094$

Hence, the probability of winning is 0.00094

Annuity A pays 1 at the beginning of each year for three years. Annuity B pays 1 at the end of each year for four years. The Mac

kiruha [24]

Answer:

Calculate the Macaulay duration of Annuity B at the time of purchase is 1.369.

Step-by-step explanation:

First, we use 0.93 to calculate the v which equals 1/(1+i).

$\frac{0+1*v+2v^{2} }{1+v+v^{2} }$ = 0.93

After rearranging the equation, we get 1.07 $v^{2}$ + 0.07v - 0.93=0

So, v=0.9

Mac D: $\frac{0+1*v+2*v^{2}+ 3*v^{2} }{1+v+v^{2}+ v^{3} }$

After substituting the value of v, we get Mac D = 1.369.

Solve for x Please help

adoni [48]

Step-by-step explanation:

$\frac{x}{x + x + 6} = \frac{9}{30}$

$\frac{x}{2x + 6} = \frac{9}{30}$

30x = 9(2x+6)

30x = 18x+54

30x-18x = 54

12x = 54

x = 54/12

= 27/6
