For ten school days, the numbers of bikes parked at a school bike rack are 10, 12, 8, 11, 13, 9, 2, 1, 9, and 12.

Lapatulllka [165]

The mean number is 8.7 and the outliers 1 and 2 reduce the mean value

<h3>How to determine the mean number?</h3>

The dataset is given as:

10, 12, 8, 11, 13, 9, 2, 1, 9, and 12.

The mean number is calculated using:

Mean = Sum/Count

So, we have:

Mean = (10+ 12+ 8+ 11+ 13+ 9+ 2+ 1+ 9+12)/10

Evaluate

Mean = 8.7

Hence, the mean number is 8.7

<h3>The outlier and how it affects the mean</h3>

Outliers are relatively far from other data elements of the dataset

In the given dataset, 1 and 2 are far from other data element.

So, the outliers are 1 and 2

Because 1 and 2 smaller than other data elements, they affect the mean by reducing the mean value

An exam consists of two parts, Section X and Section Y. There can be a maximum of 95 questions. There must be at least 20 more q

GuDViN [60]

Answer:

X + Y <= 95.

Y >= 20+ X.

Step-by-step explanation:

It is given that section X and section Y can have hardly 95 questions.

Hence either both have them has total 95 questions or less than 95 questions.

If we take X as the number of questions section X has and Y as the number of questions section Y has then X + Y <= 95.

Also it is given that Y has at least more 20 more questions than Y has. Hence Y can have 20 more question than X has or more than 20 more question than X.

That is Y >= 20+ X.

As shown in the graph the line passing through (95, 0) and (0, 95) the arrows are towards the origin because the origin satisfies the equation.

In the other line the origin that is (0, 0) does not satisfy the equation. Hence the arrows will not be towards the origin.

How do you express sin x + cos x in terms of sine only?

frez [133]

Answer:

$\sin x + \sqrt{1-\sin^2x}$

Step-by-step explanation:

Given: sin x + cos x

To change the given trigonometry expression in term of sine only.

Trigonometry identity:-

$\sin^2x+\cos^2x=1$
$\cos x=\sqrt{1-\sin^2x}$

Expression: $\sin x+\cos x$

We get rid of cos x from expression and write as sine form.

Expression: $\sin x + \sqrt{1-\sin^2x}$ $\because \cos x=\sqrt{1-\sin^2x}$

Hence, The final expression is only sine function.
