Answer:

n+1 or n

Step-by-step explanation:

a whole number contains 0 no integers

and that means n or n+1

Answer:

Step-by-step explanation:

<h2>I am not sure but i think it may be infinite, because a whole number can be an integer so can it just keep reducing the numbers like -20, -21,-23,... and so on. I think i might be wrong though. Let me know if this helps!</h2>

If f(x)=sqrt of (4sinx+2) then f'(0)=

Fantom [35]

We are given the function f(x)=sqrt of (4sinx+2) and is asked to find the first derivative of the function when x is equal to zero.

f(x)=sqrt of (4sinx+2)
f'(x) = 0.5 (4sinx+2) ^ -0.5 * (4cosx)
f'(0) = 0.5 (4sin0+2) ^ -0.5 * (4cos0)
f'(0) = 0.5 (0+2) ^ -0.5 * (4*1)
f'(x) = 0.5 (2) ^ -0.5 * (4)
f'(x) = -.1.65

Given that (x - 2) is a factor of this polynomial, use the Factor Theorem to find the value of a.

IceJOKER [234]

The factor theorem states that if (x-a) is a factor of P(x) the P(a) = 0 so we can write, for this polynomial:

2^(4) - 3(2)^3 + A(2)^2 - 6(2) + 14 = 0

16 - 24 + 4A - 12 + 14 = 0
4A = -16+24 + 12 - 14 = 6
A = 6/4 = 1.5

A major hurricane is a hurricane with wind speeds of 111 miles per hour or greater. During the 20th century the mean number of t

Bas_tet [7]

Answer:

a) 0.3293 = 32.93% probability that the number of major hurricane to strike U.S mainland in any any give year is exactly one.

b) 0.878 = 87.8% probability that the number of major hurricane to strike U.S mainland in any any give year is at most one.

c) 0.122 = 12.2% probability that the number of major hurricane to strike U.S mainland in any any give year is more than one.

Step-by-step explanation:

We have the mean during an interval, which means that the Poisson distribution is used to solve this question.

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

During the 20th century the mean number of the major hurricanes to strike U.S mainland per year was 0.6.

This means that $\mu = 0.6$

Find the probability that the number of major hurricane to strike U.S mainland in any any give year is:

a) Exactly one

This is P(X = 1). So

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 1) = \frac{e^{-0.6}*0.6^{1}}{(1)!} = 0.3293$

0.3293 = 32.93% probability that the number of major hurricane to strike U.S mainland in any any give year is exactly one.

b) At most one

This is:

$P(X \leq 1) = P(X = 0) + P(X = 1)$

Then

$P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}$

$P(X = 0) = \frac{e^{-0.6}*0.6^{0}}{(0)!} = 0.5488$

$P(X = 1) = \frac{e^{-0.6}*0.6^{1}}{(1)!} = 0.3293$

$P(X \leq 1) = P(X = 0) + P(X = 1) = 0.5488 + 0.3292 = 0.878$

0.878 = 87.8% probability that the number of major hurricane to strike U.S mainland in any any give year is at most one.

c) More than one

This is:

$P(X > 1) = 1 - P(X \leq 1) = 1 - 0.878 = 0.122$

0.122 = 12.2% probability that the number of major hurricane to strike U.S mainland in any any give year is more than one.
