Answer:

X = 32 meters.

Step-by-step explanation:

  • Let the unknown distance be X.

<u>Given the following data;</u>

  • Distance = 8 meters per hour
  • Time = 4 hours

To find how many meters he would cover in four hours;

1 hour = 8 meters

4 hours = X meters

Cross-multiplying, we have;

X = 8 * 4

<em>X = 32 meters.</em>

kirill115 [55]

The question is incomplete. The complete question is :

The National Coffee Association reported that 62% of U.S. adults drink coffee daily. A random sample of 225 U.S. adults is selected. Round your answers to at least four decimal places as needed.

Required:

a. Find the mean μ.

b. Find the standard deviation σ.

c. The standard deviation σ.

Solution :

a). Percentage of the US adults who drinks coffee daily = 62%

Therefore, the mean, μ = 0.62

b). We know, p = μ = 0.62

And n = 225

Therefore, the standard deviation is given by :

$\sigma=\sqrt{\frac{p\times (1-p)}{n}}$

 $=\sqrt{\frac{0.62\times (1-0.62)}{225}}$

 $=\sqrt{\frac{0.62\times 0.38}{225}}$

 $=0.0324$

c). Standard deviation, σ = 0.0324

ANSWER ASAP PLEASE AND SHOW YOUR WORK!!!!
IgorLugansk [536]

Answer:

f(-x)= -f(x) so, the given function f(x)= x^3-2x is Odd

Step-by-step explanation:

We need to determine if the function f(x)= x^3-2x is Even, Odd, or Neither.

Determining if a function f(x) is even or not we put x=-x and check

If f(-x)=f(x) the function is even

if f(-x)= -f(x) the function is odd

So, Putting x =-x and determining if the given function f(x)= x^3-2x is Even, Odd, or Neither.

f(x)= x^3-2x\\Put \ x=-x\\f(-x)=(-x)^3-2(-x)\\f(-x)=-x^3+2x\\f(-x)=-(x^3-2x)\\f(-x)=-f(x)

As f(-x)= -f(x) so, the given function f(x)= x^3-2x is Odd
