The correct answer between all
the choices given is the first choice or letter A. I am hoping that this answer
Answer: Option 'A' is correct
Step-by-step explanation:
Since we have given that
A be the event that Ashley drives faster than the speed limit.
P(A)=0.34
B be the event that he gets a speeding ticket.
P(B)=0.22
Probability that he drives faster than the speed limit, given that he has gotten a speeding ticket i.e.
P(A|B)=1
but for A and B to be independent ,
P(A).P(B)= P(A and B)
0.34×0.22=0.0748
but,
[tex]P(A\mid B)=\dfrac{P(A\cap B)}{P(B)}\\\\1=\dfrac{P(A\cap B)}{0.22}\\\\0.22=P(A\cap B)[/tex]
So, P(A∩B) does not satisfy the condition.
Hence, A and B are not independent events.
Option 'A' is correct as they are dependent events.
II has a radius of 1.47 inches and weighs 11 grams per cubic inch Which of the following
4. A spherical baseball has a radius of 1.47 inches and weighs 11
is closest to the weight of the entire baseball?
(1) 128 grams
(3) 146 grams
(2) 135 grams
(4) 158 grams
2. 135 grams is your answer
The mass of the baseball is 146 grams.
What is mass?Mass refers to the weight of an object. It is measured in grams (g) and kilograms (kg).
How to find the mass of the baseball?According to question we have a spherical ball of radius 1.47 inches and density of ball is 11g/cubic inch.
We know that density = mass/volume ...............(i)
Volume of sphere is given by
Volume = 4π(radius)³/3
volume = 4π(1.47)³/3
volume = 13.3057 inches³ By (i)
mass = density x volume
mass = 11 x 13.3057mass
= 146.36g

Draw a line with a negative slope
Sorry, I didn't fully understand your initial question. I'll answer it now.
A quick and easy equation you can always use is y = -x + 2
Put one point on (0, 2) and put another point on (2, 0) (since a slope of 2/2 would cancel out) Then connect the points, and you're done.
Y=-x+2 is an equation that you can use

Which coordinate pair identifies a point in the third quadrant of the coordinate plane?
A) (0, 6)
B) (−6, 2)
C) (2, −6)
D) (−6, −2)
Answer:
D, (-6,-2)
Step-by-step explanation:
the first quadrant of a coordinate plane has the x coordinate being a negative number, and the y coordinate being a positive number
the second quadrant of a coordinate plane has the x and y coordinates being a positive number
the third quadrant of a coordinate plane has the x and y coordinates being a negative number
the fourth quadrant of a coordinate plane has the x coordinate being a positive number, and the y coordinate being a negative number
i have attached a graph showing the quadrants for a visual point of view
The coordinate pair that identifies a point in the third quadrant of the coordinate plane, where both x and y coordinates are negative, is (-6,-2)
Explanation:The question is asking about identifying which pair of coordinates falls into the third quadrant of the coordinate plane in mathematics. The third quadrant in a coordinate plane is the bottom-left quadrant, where both the x and y coordinates are negative.
Looking at the options: A) (0,6), B) (-6,2), C) (2,-6), and D) (-6,-2); we can clearly see that option D) (-6,-2) is the point in the third quadrant, as both coordinates are negative. The pair (-6,-2) meets this description, with -6 on the x-axis and -2 on the y-axis. So, the correct answer is option D).

Find the slope of the line that passes through the points (-6,-8) and (-6,12)
Answer:
The slope is 0. However, it is a horizontal line where x=-6.
Step-by-step explanation:
Use the equation m= y2-y1/x2-x1 to get 12--8/-6--6. Two negatives means a positive, so you get 20/0. This means there is no slope, because you cannot divide by 0. However, you notice that both x-values are -6, so you can safely assume that there is a horizontal line where x=-6.
The slope is undefined and the line is vertical and parallel to the y-axis.
Given points (-6, -8) and (-6, 12)
First, the slope of line is
Slope= (change in y/ change in x
= (12 - (-8)) / (-6 - (-6))
= (12 +8) / (-6 +6)
= 20 /0
= ∞
Since we have a division by zero in the denominator, the slope is undefined.
This indicates that the line is vertical and parallel to the y-axis.
Thus, the slope is undefined.

Let's analyze each option:
A. [tex]x = \pm\sqrt{\frac{y-k}{a}} -h[/tex].
Rearrange equation: [tex]x+h = \pm\sqrt{\frac{y-k}{a} }[/tex].
Here we can see a term of x+h, but this is not correct as the formula has (x-h). Hence this option is incorrect.

Rearrange equation: [tex](\frac{y-k}{a})^2 = x-h[/tex]
we can see that degree of y term is 2 and that of x term is 1 which not correct as in the formula x has degree =2 and y has degree. = 1.
C. [tex]k = y+(x-h)^2[/tex]
This is incorrect as the equation doesn't include 'a' whereas the formula includes 'a'.
D. [tex]a = \frac{y-k}{(x-h)^2}[/tex]

Write the equation of the line that passes through the points (3, 6) and (5, 18) using function notation.
Answer:
[tex]f(x) = 6x -12[/tex]
Step-by-step explanation:
We must write the function of the line in the form [tex]f (x) = mx + b[/tex]
First calculate the slope m
[tex]m =\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]y_2 = 18\\y_1 =6\\x_2=5\\x_1=3[/tex]
[tex]m= \frac{18-6}{5-3} = 6[/tex]
Then
[tex]f(x) = 6x +b[/tex]
To have b replaced a point in the function
[tex]f(3)=6 = 6(3) +b\\\\6-18= b\\\\b=-12[/tex]
Finally the function is
[tex]f(x) = 6x -12[/tex]
ANSWER
[tex]f(x) = 6x - 12[/tex]
EXPLANATION
The given line passes through the points (3, 6) and (5, 18).
The slope of this line given by:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
We plug in the points to get,
[tex]m = \frac{18 - 6}{5 - 3} = \frac{12}{2} = 6[/tex]
The equation is given by
[tex]y-y_1=m(x-x_1)[/tex]
We plug in the point and the slope to get,
[tex]y - 6 = 6(x - 3)[/tex]
[tex]y - 6 = 6x - 18[/tex]
[tex] y = 6x - 18 + 6[/tex]
[tex]y = 6x - 12[/tex]
Using function notation, we have
[tex]f(x) = 6x - 12[/tex]
A raised garden bed contains 32 cubic feet of dirt the bed is 6 feet wide and 8 feet long. how deep is the dirt?
Answer:

The angular velocity of a point with radius 8 feet is 10 pi radians per second. Find the speed of the point.
0.8pi ft/sec
1.25pi ft/sec
80pi ft/sec
Answer:
80π feet/ second.
Step-by-step explanation:
Angular velocity of a point = 10π radians per second
Radius of the circle is 8 feet.
We know the formula of angular velocity is
Angular velocity = [tex]\frac{speed}{radius}[/tex]
10π = [tex]\frac{speed}{8}[/tex]
Speed = 80π feet/ second.
Option C is the answer.
Answer: [tex]80\pi\text{ ft/sec}[/tex]
Step-by-step explanation:
Formula : [tex]\text{Speed= Angular velocity x Radius}[/tex] (1)
We are given that , The angular velocity of a point with radius 8 feet is 10 pi radians per second.
i.e. Radius = 8 feet
Angular velocity = [tex]10\pi[/tex] radians per second.
Then, the speed of the point will be :-
[tex]\text{Speed= }10\pi \times 8[/tex] [using (1)]
[tex]=80\pi\text{ ft/sec}[/tex]
Hence, the speed of the point [tex]=80\pi\text{ ft/sec}[/tex]

Answer:
x + 1
Step-by-step explanation:
Is that a lone x on the left hand side? I will assume so.
Let y be the value of the side marked with a ?.
x + 3x + 1 + x + y = 6x + 2 collect the like terms on the left.
5x + 1 + y= 6x + 2 Subtract 1 from both sides.
5x + 1-1 +y = 6x + 2-1 Combine
5x + y = 6x + 1 Subtract 5x from both sides.
5x-5x + y = 6x -5x +1 Combine
y =x + 1

How do I solve a system of equations using substitution?
Answer:
A way to solve a linear system algebraically is to use the substitution method. The substitution method functions by substituting the one y-value with the other. We're going to explain this by using an example. We can substitute y in the second equation with the first equation since y = y.

Select the expression below that is equal to 6(9 - m).
Answer:
The answer would be m= -9
Step-by-step explanation:

You will multiply the 6 with the 9 and -m inside of the parenthesis
54-6m
Divide by -6 on both sides and you will get m= -9
I hope this helps you with this question and have a nice weekend
The equivalent expression to 6(9 - m) is 54 - 6m, determined by applying the distributive property of multiplication over addition and subtraction.
The expression given is 6(9 - m). To identify an expression equal to this, we should look for expressions that maintain the same relationship between the numbers and the variable m. When we distribute the 6 across the parentheses, we multiply 6 by 9, and 6 by -m, resulting in 54 - 6m.
Distributing a number across a subtraction in a parenthesis follows the distributive property of multiplication over addition and subtraction, which allows us to multiply each term inside the parentheses by the number outside.
