What is the length of AB?

Answer:

No, the events are not independent.

Step-by-step explanation:

Suppose that there are two events, A and B.

Such that first happens the event A and then the event B.

If the outcome of event A affects the probabilities for the different outcomes of event B, then the events are dependent.

In this case, if we have only the event "selecting a student who has brown eyes"  (at random)

The probability is equal to the quotient between the total number of students with brown eyes, and the total number of students, then this probability is:

P = 91/200 = 0.455...

Now, if we first impose the "selecting a female", now when we want to select a student with brown eyes we will look only at the female students.

In this case, there are 32 with brown eyes and a total of 90 female students, then the probability of selecting a female with brown eyes at random is:

P = 32/90 = 0.355...

So the probability is different, which means that the events "selecting a female" and "selecting a student who has brown eyes" are not independent.

Answer:

D

Step-by-step explanation:

-8x + y = -3..... (equ 1)

9x - y = 3.....(equ2)

y = 8x - 3

-y = -9x + 3(divide both sides by -1*)

hence ..y = 9x - 3

then write y = y in terms of x

which will give you 8x - 3 = 9x - 3

and solve for x which will be N/A

Answer:

What angle should a ramp be?

Maximum slope for hand-propelled wheelchair ramps should be 1" of rise to every 12" of length (4.8 degree angle; 8.3% grade). Maximum slope for power chairs should be 1.5" rise to 12" length (7.1 degree angle; 12.5% grade). Minimum width should be 36" (inside rails) - (48" is ideal)

Answer:

22 (4th option)

Step-by-step explanation:

The side lengths are useless.

Pay attention to the angles.

<QRP=68 degrees.

Vertical angles make it so <SRT=68

180-90(right angle)-68=22 degrees

785·20%=157

785-157=628

Answer:

You will pay $628 for a item with original price of $785 when discounted 20%. In this example, if you buy an item at $785 with 20% discount, you will pay 785 - 157 = 628 dollars.

Answer:

  y = 3/4x -7/4  or  y = 0.75x -1.75

Step-by-step explanation:

The two point form of the equation of a line is useful when you are given 2 points and asked for the equation.

  y = (y2 -y1)/(x2 -x1)·(x -x1) +y1

  y = (35 -14)/(49 -21)·(x -21) +14 . . . . . . fill in given points

  y = 21/28(x -21) +14 . . . . . . . . . . . . . . . simplify a bit

  y = 3/4(x -21) +14 . . . . . . . . . . . reduce the fraction

  y = 3/4x -15 3/4 +14 . . . . . . . .eliminate parentheses

  y = 3/4x -7/4  or  y = 0.75x -1.75

Answer:

Is the dilation an enlargement or reduction?

Reduction

The point of dilation is about what coordinate?

0,0

What is the scale factor?

1/3

Step-by-step explanation:

The dilation is a reduction. The point of dilation is about coordinate (0,0).  The scale factor is 1/3.

A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.

On a coordinate plane, the pre-image rectangle has points (0, 0), (6, 0), (6, -3), and (0, -3).

The image has points (0, 0), (2, 0), (2, -1), and (0, -1).

The required figure has been attached below which represents the dilation.

As we can see that the dilation is a reduction.

The point of dilation is about coordinate (0,0).

This result of dilating a given triangle with a scale factor is 1/3.

Answer:

[tex]y=-2\\[/tex]

Step-by-step explanation:

Use the values of the unit circle to get the (x,y) when Θ=[tex]\frac{11\pi}{6}[/tex], which is [tex](\frac{\sqrt{3}}{2}, -\frac{1}{2})[/tex].

The cosecant (csc) function is the reciprocal of the sine function, so we take the y value and take the reciprocal of it, which is -2.

Answer:

If two triangles are similar it means that all corresponding angle pairs are congruent and all corresponding sides are proportional. However, in order to be sure that two triangles are similar, you do not necessarily need to have information about all sides and all angles.
