Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{5}}}}}

Step-by-step explanation:

Given data : 6 , 3 , 2 , 1 , 9 , 9

Σfx = 6 + 3 + 2 + 1 + 9 + 9 = 30

N ( total number of observation ) = 6

<u>Finding </u><u>the</u><u> </u><u>mean</u><u> </u>

\boxed{ \sf{mean =  \frac{Σfx}{N} }}

\dashrightarrow{ \sf{mean =  \frac{30}{6} }}

\dashrightarrow{ \sf{mean = 5}}

Hope I helped!

Best regards! :D

An editor has a stack of k documents to review. The order in which the documents are reviewed is random with each ordering being
ladessa [460]

Using the probability concept, it is found that there is a \mathbf{\frac{1}{k}} probability that “Relaxation Through Mathematics” is first to review.

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

In this problem:

  • There is a total of k documents to be reviewed, hence T = k.
  • Of those documents, 1 is named “Relaxation Through Mathematics”, hence D = 1

The <em>probability </em>is:

p = \frac{D}{T} = \frac{1}{k}

Which number line represents the solution of 4 - 3x &gt; 13?
Oksanka [162]

Answer:

x

Step-by-step explanation:

Given inequality:

4-3x>13

In order to represent the solution on the number line, we will first solve the given inequality.

We have

4-3x>13

Subtracting both sides by 4.

4-3x-4>13-4

-3x>9

Dividing both sides by -3.

\frac{-3x}{-3} [On dividing both sides by a negative number the sign of the inequality reverses.]

x

So, solution of this inequality will range from -3 to -∞

The number line is represented below.

Find the equation of the line through the point (7,-6) with the slope -15/13
gayaneshka [121]

Answer:

y + 6 = -15/13(x-7)

Step-by-step explanation:

Substitute m= -15/13 and the point (7,-6) into the point slope form.

y --6 = -15/13 (x - 7)

y + 6 = -15/13(x-7)

A factory that manufactures bolts is performing a quality control experiment. Each object should have a length of no more than 1
xeze [42]

The test statistic z  is 2.33, the p-value corresponding to the test statistic z value is 0.0099.

<h3>What is Probability?</h3>

Probability is the measure of the likeliness of happening of an event.

The mean of the data is 15.07 centimeters

The standard deviation of the data is 0.26 centimeters.

n = 75

Significance Level ∝ = 0.01

According to the null and alternative hypothesis

Hₐ : \rm \mu ≤15  vs H₁ : \rm \mu >15

The test statistic z  is given by

\rm Z = \dfrac{(X-\mu)}{\sigma/\sqrt{n}}

Z = ( 15.07 -15)/(0.26/√75)

Z = 2.33

The p-value corresponding to z value is 0.0099

as p-value < significance level, therefore the H₁ : \rm \mu >15 is acceptable.

No, significant evidence is not present to tell that the length of bolts is actually greater than the mean value at a significance level of 0.01.
