Answer:

1.)A rhombus is a quadrilateral with four equal-length sides and opposite sides parallel to each other. All rhombuses are parallelograms, but not all parallelograms are rhombuses.

2.) When all 4 sides of a rectangle are equal then the rectangle is a square. So, a rectangle can also sometimes be a square

3.)If you have a rhombus with four equal interior angles, you have a square. A square is a special case of a rhombus, because it has four equal-length sides and goes above and beyond that to also have four right angles. Every square you see will be a rhombus, but not every rhombus you meet will be a square.

4.)Yes. Every square is a closed figure, and every square has 4 straight sides, so every square is a quadrilateral.

Answer:

(a) [tex]x = 60[/tex]

(b) [tex]x = 2.64[/tex]

(c) [tex]x=15[/tex]

Step-by-step explanation:

Solving (a):

[tex]\frac{1}{4}x + \frac{2}{5}x = 39[/tex]

[tex]\frac{x}{4} + \frac{2x}{5} = 39[/tex]

Take LCM

[tex]\frac{13x}{20} = 39[/tex]

Multiply through by 20

[tex]20 * \frac{13x}{20} = 39 * 20[/tex]

[tex]13x = 39 * 20[/tex]

[tex]13x = 780[/tex]

Solve for x

[tex]x = 780/13[/tex]

[tex]x = 60[/tex]

Solving (b):

[tex]0.6x + 0.5x = 2.9[/tex]

This gives:

[tex]1.1x = 2.9[/tex]

Solve for x

[tex]x = \frac{2.9}{1.1}[/tex]

[tex]x = \frac{29}{11}[/tex]

[tex]x = 2.64[/tex]

Solving (c):

[tex]\frac{3}{5}x = 9[/tex]

Multiply both sides by [tex]\frac{5}{3}[/tex]

[tex]\frac{5}{3}*\frac{3}{5}x = 9 * \frac{5}{3}[/tex]

[tex]x = 9 * \frac{5}{3}[/tex]

[tex]x = \frac{9 *5}{3}[/tex]

[tex]x = \frac{45}{3}[/tex]

[tex]x=15[/tex]

Answer:

D is located at (-5, 2)

Answer:

point D

Step-by-step explanation:

(-5, 2) can be represented as (x, y)

This mean when x = -5, y is = 2

We need to trace the x-axis to -5 and get the corresponding point at y equals to 2

Tracing the point on the graph, we find the point D is at x = -5 and y = 2

Hence, point D is located at (-5, 2)

Answer:

sigma should be used

Step-by-step explanation:

Given that The mean length of time in jail from the survey was four years with a standard deviation of 1.9 years.

The above given is for sample of 27 size.

For hypothesis test to compare mean of sample with population we can use either population std dev or sample std dev.

But once population std deviation is given, we use only that as that would be more reliable.

So here we can use population std deviation 1.4 only.

If population std deviation is used we can use normality and do Z test

Answer:

  x/50 = 40/100

  x = 20

Step-by-step explanation:

It is useful to remember that the symbol % is a shorthand way to write /100. (Similarly, the symbol ‰ is a shorthand way to write /1000.) This means the number 40% represents the ratio 40/100. In decimal, that is 0.40 (forty hundredths).

When this is the fraction that represents the number of test questions that are correct, you can see that the proportion should be ...

  correct / total questions = x / 50 = 40 / 100 . . . . the desired proportion

Multiplying by 50 gives the value of x:

  x = 50(0.40)

  x = 20 . . . . the value of x

Answer:

a) 0.0002 = 0.02% probability that all are silver.

b) 0.0033 = 0.33% probability that 5 are red and 2 are black

c) 0.0345 = 3.45% probability that 4 are red and the rest are silver

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the order in which the cars were selected is not important, so we use the combinations formula.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

(a) all are silver

Desired outcomes:

7 silver cars, from a set of 9. So

[tex]D = C_{9,7} = \frac{9!}{7!(9-7)!} = 36[/tex]

Total outcomes:

7 cars from a set of 8 + 9 + 5 = 22. So

[tex]T = C_{22,7} = \frac{22!}{7!(22-7)!} = 170544[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{36}{170544} = 0.0002[/tex]

0.0002 = 0.02% probability that all are silver.

(b) 5 are red and 2 are black

Desired outcomes:

5 red, from a set of 8

2 black, from a set of 5

[tex]D = C_{8,5}*C_{5,2} = \frac{8!}{5!(8-5)!}*\frac{5!}{2!(5-2)!} = 56*10 = 560[/tex]

Total outcomes:

7 cars from a set of 8 + 9 + 5 = 22. So

[tex]T = C_{22,7} = \frac{22!}{7!(22-7)!} = 170544[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{560}{170544} = 0.0033[/tex]

0.0033 = 0.33% probability that 5 are red and 2 are black

c) 4 are red and the rest are silver

Desired outcomes:

4 red, from a set of 8

3 silver, from a set of 9

[tex]D = C_{8,4}*C_{9,3} = \frac{8!}{4!(8-4)!}*\frac{9!}{3!(9-3)!} = 70*84 = 5880[/tex]

Total outcomes:

7 cars from a set of 8 + 9 + 5 = 22. So

[tex]T = C_{22,7} = \frac{22!}{7!(22-7)!} = 170544[/tex]

Probability:

[tex]p = \frac{D}{T} = \frac{5880}{170544} = 0.0345[/tex]

0.0345 = 3.45% probability that 4 are red and the rest are silver

Answer:

A

Step-by-step explanation:

Both criteria require that two pairs of angles be congruent, but for congruence, you also need to know that the included sides are congruent, so that the figures are the same size. The AA similarity criterion shows only that the two triangles are the same shape. Thus option A is correct.

According to the Angle-Angle (AA) criterion, two triangle being considered comparable if "two angles from one triangle are equally equivalent to two angles of some other triangle."

According to the ASA congruence rule, two triangles are compatible when their two covered sides and two contained angles are equivalent to each other. However, thus according to AAS, if two triangles have two angles as well as one side that are identical to one another, then perhaps the triangles are congruent.

Because ASA and AAS are identical since it follows that if two images in one triangle are equal with two angles in another, therefore the third angles must likewise be identical. Therefore, option A is the correct option.
