The player has a 0.293 percent probability of getting the subsequent number of hits in the subsequent four at-bats.
What does probability mean in math?Probability is a branch of mathematics that deals with numerical representations of the likelihood of an event occurring or of a proposition being true. The probability of an event is a number between 0 and 1, with 0 approximately denoting impossibility and 1 denoting certainty.
In light of the information provided,
designate X as the random variable indicating the player's hit total during his subsequent four at-bats.
Assume that the player hits or misses on each of the following four at-bats in a random order. Consider it a success if the player gets a hit as well.
The probability of "success" is because of the batting average, which is 0.330.
In this case, x can be thought of as the overall success rate across the four at-bats. Inferring that X has a binomial distribution with p=0.330 as its parameters
n=4 p=0.330
Since p denotes the probability of success, the probability of failure is
q=1-0.330
=670
The probability mass function of x here is
f(x)={(4 0)*(0.330)ˣ (0.670)⁽⁴⁻ˣ⁾
The probability that the player will get exactly 2 hits, that is, is calculated below:
P(2)=F(2)={(4+2)*(0.330)² (0.670)²
=6[0.04888]
=0.29328
Thus, the probability that the player will get exactly 2 hits is 0.239.

Step-by-step explanation:
Kiley and her parents traveled to visit her grandmother. They drove 24.3 miles from their house to the airport in 12 hour. At the airport, they exited the car and walked for 34 hour to the waiting area by the gate to board their plane. Their walk covered 1.2 miles. From the waiting area, they walked another 0.1 mile to board the plane. The plane left the gate 45 minutes after they arrived at the waiting area. The plane flew 346 miles in 214 hours. After the plane landed, Kiley and her parents walked for 30 minutes, covering 1.1 miles, before they found a cab. It was a 15-minute cab ride to get to Kiley’s grandmother’s house, which was 12.3 miles away.Answer the following questions about Kiley’s trip. All questions are written in terms of an average rate. Assume that an average rate includes the time that Kiley is at rest (that is, not moving).In this task, you will write the ratio of miles to hours for each leg of Kiley’s trip. You will then, express the ratio as a decimal number. Next, you will find the unit rate in miles per hour (mph) for each leg of the trip. If your unit rate includes a repeating decimal number, you must indicate which digits repeat (for example, write 0.3¯when the 3 repeats.) A description of each leg is listed below in parts A through F.
Given:
The car ride from Kiley's house to the airport.
Distance =24.3 miles.
Time =1/2 hour.
We know that
[tex]\text{Average rate =}\frac{\text{Distance}}{\text{time}}[/tex]Substitute Distance =24.3 miles and time =1/2 hour to compute the average rate of the car ride from Kiley's house to the airport.
[tex]=\frac{24.3\text{ miles}}{\frac{1}{2}\text{hours}}[/tex][tex]\text{ Use }\frac{\frac{a}{b}}{\frac{c}{d}}=\frac{a}{b}\times\frac{d}{c}\text{.}[/tex][tex]=24.3\times\frac{2}{1}\text{ miles per hour}[/tex][tex]=24.3\times2\text{ miles per hour}[/tex][tex]=48.6\text{ miles per hour}[/tex]Hence the average rate of the car ride from Kiley's house to the airport is 48.6 miles per hour.
2)
Given that they walked 3/4 hours to the waiting area and covered the distance of 1.2 miles.
Distance =1.2 miles.
Time =3/4 hours.
we know that
[tex]\text{Average rate =}\frac{\text{Distance}}{\text{time}}[/tex]Substitute distance =1.2 miles and time =3/4 hours to compute the average rate of the walk from the car to the waiting area by the gate, at the airport.
[tex]=\frac{1.2\text{ miles}}{\frac{3}{4}\text{ hours}}[/tex][tex]=1.2\times\frac{4}{3}\text{ miles per hour.}[/tex][tex]=\frac{1.2\times4}{3}\text{ miles per hour.}[/tex]Multiplying 1.2 and 4, we get 4.8
[tex]=\frac{4.8}{3}\text{ miles per hour.}[/tex]Dividing 4.8 by 3, we get 1.6
[tex]=1.6\text{ miles per hour.}[/tex]Hence at the airport, the average rate of the walk from the car to the waiting area by the gate is 1.6 miles per hour.

well, the tell-tale part in the points will be the coordinates, hmmm now, the x-coordinate for both points is the same, well, that simply means is a vertical line. Check the picture below.
Find the equation of the line.
a line that is perpendicular to the graph of y=-3x +2 and
contains the point (3,-3)
Answer: y = -3x + 6
Step-by-step explanation:
If it is perpendicular to the line -3x + 2, then it's slope should also be -3.
The standard form of a line is y = mx + b. As our slope is -3, we have that our line is y = -3x+b. Now, let's put the given point into the line. x = 3 and y = -3, so -3 = -3*3 + b. Hence, b = -3+9 = 6. The equation of the line is y = -3x + 6.
What is the measure of angle 1, angle 5, angle 2, angle 8, and angle 7? Angle 4 = 72 degrees.
The unknow angles are as follows:
m∠1 = 108 degreesm∠2 = 72 degreesm∠5 = 108 degrees.m∠7 = 108 degreesm∠8 = 72 degreesHow to find angles in parallel lines?When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, vertically opposite angles etc.
Therefore,
m∠4 = 72 degrees
Hence,
m∠1 + m∠4 = 180 (angle on a straight line)
m∠1 = 180 - 72
m∠1 = 108 degrees
m∠2 = m∠4 (vertically opposite angles)
Vertical angles are the angles formed when two lines intersect each other. Vertical angles are congruent.
Therefore,
m∠2 = 72 degrees
m∠5 = m∠1 (corresponding angles)
Corresponding angles are angles that occur on the same side of the transversal line and are equal in size.
m∠5 = 108 degrees.
m∠7 = m∠5(vertically opposite angles)
m∠7 = 108 degrees
m∠8 = m∠2 (alternate exterior angles)
Alternate exterior angles are congruent.

In the following exercise, two sides and an angle are given. First determine whether the information results in no triangle, one triangle, or two triangles. Solve the resulting triangle.
a=229,b=244, and A = 37.8°
By the Law of Sines,
[tex]\frac{\sin B}{b}=\frac{\sin A}{a} \\ \\ \sin B=\frac{b \sin A}{a} \\ \\ =\frac{244\sin 37.8^{\circ}}{229} \\ \\ B \approx 37.42^{\circ}, 142.58^{\circ}[/tex]
Of these, only 37.42° is a possible value of B (sum of angles of a triangle is 180°).
So, we have that:
[tex] a=229, b=244, A=37.8^{\circ}, B=\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)[/tex]
Angles of a triangle add to 180°, so:
[tex]C=180^{\circ}-A-B=142.2^{\circ}-\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)
[/tex]
Using the Law of Sines again,
[tex]\frac{c}{\sin C}=\frac{a}{\sin A} \\ \\ c=\frac{a \sin C}{\sin A} \\ \\ =\frac{244\sin \left(142^{\circ}-\arcsin \left(\frac{244 \sin 37.8^{\circ}}{229} \right) \right)}{\sin 37.8^{\circ}}[/tex]
So, there is one possible triangle, where:
[tex]a=229 \\ \\ b=244 \\ \\ c=\frac{244\sin \left(142^{\circ}-\arcsin \left(\frac{244 \sin 37.8^{\circ}}{229} \right) \right)}{\sin 37.8^{\circ}} \\ \\ A=37.8^{\circ} \\ \\ B=\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right) \\ \\ C=142.2^{\circ}-\arcsin \left(\frac{244\sin 37.8^{\circ}}{229} \right)[/tex]

Write the vertex form of the following function. (fill in each blank with the correct numerical
value: include the sign where needed)
An absolute value function with a vertex of (-12,10) and passes through the points (4, 6) and
(-8, 9).
Answer:
-1/4 Abs(x+12) + 10
Step-by-step explanation:
The vertex form of an absolute function is of the form
y = a|x -h| + k here |x-h| is the absolute value
where (h, k) are the coordinates (x, y) of the vertex
The vertex is given as (-12, 10)
So h = -12, k = 10
Plugging these in we get the vertex form as
y = a|x - (-12)| + 10
y = a|x + 12| + 10
All it remains is to find a
Given point (4, 6) as a point on the graph, plug these values
y = 6 = a|4 + 12| + 10
6 = a|16| + 10
6 = 16a + 10 since absolute value of a positive number is the number
Switch sides
16a + 10 = 6
Subtract 10 from both sides:
16a + 10 - 10 = 6 - 10
16a = -4
a = -1/4
So the equation of the function is
y = -1/4|x + 12| + 10
The second point is not needed to derive the function equation but let's use it to verify our calculated equation
Point (-8, 9)
Plug x = -8, into y = -1/4|x + 12| + 10
=> y = -1/4|-8+12| + 10
=> y = -(1/4)·4 + 10
=> y = -1 + 10
= y = 9 which matches with the y -coordinate of the second point
So everything looks cool
Final Solution
-1/4 Abs(x+12) + 10

Explanation:A circle's arc can be formed by any two points on its circumference.
A circle's arc length (S) = r(θ), where r is the radius and theta is the central angle in radians.
Given WY = XZ = 6,
So YZ = TZ = 3radius
and m∠XY = 140°.
so, m∠YZ = 180° - 140°. (As a semicircle with a central angle of 180°.)
m∠YZ = 40°.

He had determined that the outside temperature (in Fahrenheit) shared a linear relationship with the number of times the snowy tree cricket would chirp per . If you count the number of cricket chirps per (while sitting inside your warm house), then you can find the temperature outside. In his research, Dolbear concluded that for every extra cricket chirp per second, the temperature was 1/4*F higher. Furthermore, he found that when the number of cricket chirps per minute was 120, the temperature outside was 70*F.

The equation y = 2x² - 12x + 23 describes the function graph that includes a vertex at (3, 5) and passes through the point (5, 13).
What does a parabolic equation look like in vertex form?The vertex of a parabolic equation is at the point and the vertex form is y = a(x - h)2 + k, where a, h, and k are constants (h, k).
How do you answer this dilemma?Find the function whose graph has the vertex at (3, 5) and passes through the point in the question (5, 13).
Assuming it to be a parabolic function, we know that a parabolic equation's vertex form is y = a(x - h)2 + k, where a, h, and k are constants, and the vertex is located at the position (h, k).
As the vertex of the necessary function is at the position (3, 5), we may substitute h = 3 and k = 5 to obtain the following equation in the above equation:
y = a(x - 3)² + 5
Now that we know that the graph passes through the point (5, 13), we can change the original equation to read:
13 = a(5 - 3)² + 5,
or, 13 = 4a + 5,
or, 4a = 13 - 5 = 8,
or, a = 2.
We obtain the following from the equation y = a(x - h)2 + k by inserting a = 2, h = 3, and k = 5:
y = 2(x - 3)² + 5,
alternatively, y = 2(x² - 6x + 9) + 5,
alternatively, y = 2x² - 12x + 18 + 5,
Alternatively, y = 2x² - 12x + 23.
As a result, the function graph with the vertex at (3, 5) and the point of intersection (5, 13) yields the equation y = 2x² - 12x + 23.

You bike 11 1/4 miles from your house to a. State park. You travel 1/6 of that distance in the woods. You bike along the bank of a stream for the last 2/5 of the woods. On how many miles of your trip do you bike along the bank of the stream?
Answer:
9/10 mile
Step-by-step explanation:
Distance from house to state park = 11 1/4 miles = 45/4 miles
Distance through woods
[tex]\dfrac{1}{6}\cdot \dfrac{45}{4}\\\\=\dfrac{9}{4} \text { miles}\\[/tex]
Since the distance along the stream is 2/5 of the distance in the woods,
the distance biked along the stream
= 9/4 x 2/5 = 18/20 = 9/10 mile
