x in simplest radical form with a rational denominator.

Answer:
### Properties of a right angled triangle:

The length of sides x in the simplest radical form is** 2√2**

- One of the angle is equals to
**90 degree.** - The sides can be found using Pythagoras theorem
**Trigonometric ratios**can be used to find the angles.

Let's find x using trigonometric ratios

**sin ∅ = opposite / hypotenuse**

Therefore,

**sin 30° = √2 / x**

x sin 30° = √2

x = √2 / sin 30°

x =

x = × 2

**x = 2√2**

**Answer: Lyrics B**

**Step-by-step explanation:**

**The investigation about the operating time of cordless toothbrushes is in first place associated to two tails experiment since investigation call for evalution of values under and above any given value (mean value). On the other side investigation of two different manufactures implies totally independent samples, unless these two companies have a commercial relationship which is not express in the problem ststement. Therefore the answer is lyrics B**

**The questions does not look complete, we can complete the question thus**

**The following represent matrices and the dimension of each is also stated below. A is a matrix of size 4X2 B is a matrix of size 3X5 C is a matrix of size 7X2 D is a matrix of size 5X4 E is a matrix of size 5X3.**

**Which of the following matrices products are defined?**

**Answer:**

EB is defined

BE is defined

BD is defined

and DA is defined

**Step-by-step explanation:**

To know that the product of two matrices are defined, the column of the first matrix must be the same as the row of the second matrix.

For example; for EB we have 5 columns for E and 5 rows for B. After this product is done it produces a matrix with dimension 3 x 3, which means 3 by 3 (3 rows by 3 columns)

Part C: Factor x2 − 4. Show your work

**Answer:**

A.2b2(x2-x-3)

B.x2+2x+2x+4

=x(x+2)+2(x+2)

=(x+2)(x+2)

C.x2-2^2

=(x+2)(x+2)

**Answer:**

The p value for this case would be:

For this case since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true proportion is not different from 0.39

**Step-by-step explanation:**

**Information given**

n=100 represent the random sample taken

X=36 represent the number of people that take E supplement

estimated proportion of people who take R supplement

is the value that we want to test

represent the significance level

z would represent the statistic

represent the p value

**Hypothesis to test**

We want to test if the true proportion is equatl to 0.39 or not, the system of hypothesis are.:

Null hypothesis:

Alternative hypothesis:

The statistic is given by:

(1)

Replacing the info we got:

The p value for this case would be:

For this case since the p value is higher than the significance level we have enough evidence to FAIL to reject the null hypothesis and we can conclude that the true proportion is not different from 0.39
