A= 1/2 h (a+b), solve for b

fenix001 [56]

Answer:

b=2A/h-a

Step-by-step explanation:

A=1/2h(a+b)

Multiplying by 2

2A=h(a+b)

Dividing by h

2A/h=a+b

Subtracting a

2A/h-a =b

b=2A/h-a

Let x be a random variable with pmf pk = c/k2 for k = 1, 2, …a. estimate the value of c numerically. note that the series conver

kaheart [24]

$f_X(x)=\begin{cases}\dfrac c{k^2}&\text{for }k\in\{1,2,\ldots\}\\0&\text{otherwise}\end{cases}$

Because this is a valid PMF, you must have

$\displaystyle\sum_{k\ge1}f_X(x)=\sum_{k\ge1}\frac c{k^2}=1$

Recall that

$\displaystyle\sum_{k\ge1}\frac1{k^2}=\dfrac{\pi^2}6$

so the above sum is

$\displaystyle\sum_{k\ge1}\frac c{k^2}=\frac{c\pi^2}6=1$

which means that you must have

$c=\dfrac6{\pi^2}\approx0.6079$

What 2 numbers divide to get 375 while multiplying to equal 38.4?

Rus_ich [418]

Answer:

Well, 375 is a composite number.

Prime factorization: 375 = 3 x 5 x 5 x 5, which can be written 375 = 3 x (5^3)

The exponents in the prime factorization are 1 and 3.

Factors of 375: 1, 3, 5, 15, 25, 75, 125, 375.

Factor pairs: 375 = 1 x 375, 3 x 125, 5 x 75, or 15 x 25. Good Luck!
