Answer:

8P1 = 8

Step-by-step explanation:

Permutation

The number of elements can be selected from a set of elements.

Let r be the number of elements want to select and n be the set of elements.

It can be written as nPr

nPr = n!/(n - r)!

To find 8P1

n= 8 and r = 1

8P1 = 8!/(8-1)! = 8!/7! = (8 x 7!)/7! = 8

Therefore 8P1 = 8

A continuous random variable X has cdf F(x)=x² b (a) Determine the constants a and b. for a < 0, for 0 < x < 1, for x &

Karolina [17]

Any proper CDF $F(x)$ has the properties

• $\displaystyle \lim_{x\to-\infty} F(x) = 0$

• $\displaystyle \lim_{x\to+\infty} F(x) = 1$

so we have to have a = 0 and b = 1.

This follows from the definitions of PDFs and CDFs. The PDF must satisfy

$\displaystyle \int_{-\infty}^\infty f(x) \, dx = 1$

and so

$\displaystyle \lim_{x\to-\infty} F(x) = \int_{-\infty}^{-\infty} f(t) \, dt = 0 \implies a = 0$

$\displaystyle \lim_{x\to+\infty} F(x) = \int_{-\infty}^\infty f(t) \, dt = 1 \implies b = 1$

Zack wanted to build a fenced in area for a dog kennel in his backyard. The fenced in space has a length of 5 1/4 feet and a wid

Radda [10]

Answer:

Zack will need 17 1/2 ft of fence

Step-by-step explanation:

To calculate this we will first pass the numbers to complete fractions

5 1/4 ft = 21/4 ft

3 1/2 ft = 7/2 ft

We have to add 2 times each side

21/4 ft + 21/4 ft + 7/2 ft + 7/2 ft =

Now we have to pass all the fractions to the same denominator

21/4 ft + 21/4 ft + 14/4 ft + 14/4 ft =

70/4 = 17 1/2

Zack will need 17 1/2 ft of fence

Answer:

the big tank can hold 2027.37 m³of water

10 small tanks can be filled

Step-by-step explanation:

r = 11, h = 16

V = (1/3)πr²h

V = (1/3)121π(16)

1936π/3 = 2027.37

2027.37/200 = 10. 136

10 tanks
