since the 3 is outside the radical then $\sqrt{9}$ = 3, hence

x = 9

using the law of radicals

$\sqrt{a}$ × $\sqrt{b}$ = $\sqrt{ab}$

we can separate the factors as

$\sqrt{24}$ × √ $x^{10}$ × √ $y^{5}$

= 2 $\sqrt{6}$ $x^{5}$ $y^{5/2}$

$\sqrt{121}$ + $\sqrt{50}$ = 11 + 5 $\sqrt{2}$

$\sqrt{20}$ × $\sqrt{63}$

= 2 $\sqrt{5}$ × 3 $\sqrt{7}$

= 6 $\sqrt{35}$

Ted wanted to determine if one brand of paper towels (Brand A) was stronger than another brand (Brand B). He performed a study

Mila [183]

Answer:

C) A one-tail test will be performed since the alternative hypothesis contains a "less than".

Step-by-step explanation:

Test may be categorized as being one tailed or two tailed depending on the inequality sign used when defining the hypothesis ` ; Hypothesis whereby the alternative hypothesis takes a not equal to (≠) are categorized as two talked as the direction of does not point to either the left or right. Conversely, alternative hypothesis which takes a less Than sign or takes a greater Than sign are classed as being one tailed as the they point to a specified direction..

For the scenario given : we are to test the claim that one is stronger than the other ;

For this knid if test it has been stated explicitly that one is greater than another ;

prove “if two angles of one triangle are congruent to two angles of a second triangle, the the third angles of the triangles are

arsen [322]

Assume that,

The two angles of one triangle are congruent to two angles of a second triangle.

To prove: The third angles of the triangles are congruent.

Since, two angles of one triangle are congruent to two angles of a second triangle.

Therefore,

$\begin{gathered} \angle C=\angle F \\ \angle A=\angle D \end{gathered}$

Adding these two we get,

$\begin{gathered} \angle C+\angle A=\angle F+\angle D \\ 180-\angle B=180-\angle E\text{ (Using angle sum property of a triangle)} \end{gathered}$

Cancelling 180 on both sides, we get

$\begin{gathered} \angle B=\angle E \\ \therefore\angle B\cong\angle E \end{gathered}$

Hence, if two angles of one triangle are congruent to two angles of a second triangle, the the third angles of the triangles are congruent.
