Answer:

0.333.. repeating = \frac{1}{3}

Step-by-step explanation:

The given number is 0.333...

The bar represents 3 continues forever.

Let's find the rational number that represents 0.333...

The rational number is in the form of \frac{p}{q}, where q ≠ 0.

Let x = 0.333...

Let's multiply both sides by 10, we get

10x = 3.33...

Now let's subtract x from 10x

10x - x  = 3.33... - 0.333..

9x = 3

Now let's divide both sides by 9, we get

\frac{9x}{9} = \frac{3}{9}

x = \frac{3}{9}

When we simplify the above, we get

x  = \frac{1}{3}

So the rational number \frac{1}{3} represents 0.333....

The overbar indicates the digit repeats forever. It is worth remembering that

0.\overline{x}=\dfrac{x}{9}\qquad\text{x = any single digit}

Your number is 3/9 = 1/3

Answer:

c. results in either of two directions can lead to rejection of the null hypothesis.

Step-by-step explanation:

A two tailed test is performed when we want to test if there is statistically significant difference from the null state. That means that if the statistic value is significantly higher or significantly lower, we will reject the null hypothesis. Both tails have rejection areas.

Mr. Williams is driving on a highway at an average speed of 50 miles per hour. His destination is 100 miles away. The
svetlana [45]

Answer:

t = -d/50 + 2

0.5 hour

Step-by-step explanation:

Given the equation:

d = 50 - 100t

The inverse function:

A.) solving for t

d = 100 - 50t

d - 100 = - 50t

Divide both sides by - 50

d/-50 - (100/-50) = - 50t/-50

-d/50 - (-2) = t

t = -d/50 + 2

B) using the inverse function:

t = -d/50 + 2

Miles driven (d) = 75, find time (t)

t = - 75/50 + 2

t = - 1.5 + 2

t = 0.5

t is in hours, therefore time left to travel is 0.5 hours or 30 minutes
