A bag contains 4 blue balls, 7 yellow balls and 4 white balls. Event A is defined as drawing a blue ball on the first draw and event B is defined as drawing a white ball on the second draw. If two balls are drawn from the bag, one after the other and not replaced, what is P(B|A) expressed in simplest form? A. B. C. D.
P(B|A) expressed in simplest form is 8/105.
What is the probability?Probability determines the chances that an event would happen. The chance of the event happening lies between 0 and 1.
P(B|A) = (number of blue balls / total number of balls) x (number of white balls / total number of balls - 1 )

Neyha has six number cards. Here are four of Neyha's cards. 8;8;8;8 The mean of all six cards is 8 The range of all six cards is 4 What are the other two cards?
After considering the given data we come to the conclusion that the two other cards are 6 and 10, under the condition that Neyha has six number cards. Here are four of Neyha's cards. 8;8;8;8.
Let us assume that the other two cards x and y.
The given mean of all six cards is 8. Then, the sum of all six cards is 48 (8×6). We have that four of the cards are 8s.
So, the summation of these four cards is 32 (8×4).
The dedicated range of all six cards is 4. Therefore, the difference between the largest and smallest card is 4.
Furthermore, we know that four of the cards are 8s, the other two cards must be different from 8.
Hence, we can consider that x and y are the smallest and largest numbers in the set.
Here we have to apply basic algebraic expression
We can perform the setting up two equations:
x + y = 48 - 32 = 16 (the summation of x and y is equivalent to the summation of all six cards minus the summation of the four 8s)
y - x = 4 (the difference considering y and x is equal to the range of all six cards)
Evaluating these equations simultaneously gives us:
y = 10
x = 6
Therefore, the other two cards are 6 and 10.

If two inches represents three feet, then two inches also represents thirty-six inches. You would then have to set up the proportion [tex]\frac{2}{36} = \frac{6.5}{x}[/tex]. Solving that proportion would get you an answer of 117 inches, equal to 9.75 feet. I hope this helps! :)
The table shows values for a quadratic function.
What is the average rate of change for this function for the interval from x = 1
to x = 3?
The average rate of change for this function for the interval from x = 1
to x = 3 will be 8. Therefore option B is correct.
How to find the average rate of change of something?Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:
[tex]\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
where when
[tex]x = x_1, y = y_1\\and \\x = x_2, y = y_2[/tex]
The average rate of change can be calculated as;
From x=1 to x=3,
y = 2 and y = 18
Therefore, based on the table, when:
[tex]x_1 = 1 y_1 = 2 \\and \\x_2 = 3, y_2 = 18[/tex]
Then:
[tex]\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]\text{Average rate} = \dfrac{18 - 2}{3-1}\\\\\text{Average rate} = \dfrac{16}{2}\\\\\text{Average rate} = 8[/tex]

Which of the following choices is a reference angle to θ = 225º?
30 degrees
45 degrees
60 degrees
90 degrees
Answer:
45 degrees
Step-by-step explanation:
A reference angle can be found by identifying its terminal side and see by what angle the terminal side is close to the x-axis.
To do this, we can subtract this given angle by the nearest 90° angle.
270° is the closest.
[tex]\textsf {Solving :}[/tex]
[tex]\implies \textsf{Reference angle = 270 - 225}[/tex]
[tex]\implies \textsf {45 degrees}[/tex]
The reference angle is the angle from the x-axis thus 45 degrees will be the reference angle to θ = 225°.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
As per the given angle,
θ = 225°
It is going to the third quadrant as shown below,
The reference angle is the angle from x-axis.
The angle from the negative x-axis will be as,
180° + x = 225°
x = 225° - 180° = 45°
Hence "The reference angle is the angle from the x-axis thus 45 degrees will be the reference angle to θ = 225°".

A function assigns the values. The function will be 8cos(2x-π)+4.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the maximum value is 12, while the minimum value is -4, therefore,
A = (Max-Min)/2 = 12-(-4)/2 = 8
D = (Max+Min)/2 = (12-4)/2 = 4

E. 39°37'
F. 38°29'
The principal value of Arccsc (1.607) to the nearest minute is 38°29'
To answer the question, we need to know what arccsc is
What is arccsc?Arccsc is the inverse of the cosec of an angle.
Let x = arccsc(1.607)
So, taking the inverse, we have
csc(x) = 1.607
Since csc(x) = 1/sinx, we have
1/sinx = 1.607
sinx = 1/1.607
sinx = 0.6223
The value of x
Taking inverse, we have
x = arcsin(0.6223)
x = 38.483°
Since 60' = 1°, we have
x = 38 + 0.483° × 60'/1°
x = 38° + 28.98'
x = 38°28.98'
x ≅ 38°29'
