Step-by-step explanation:
Jessica went deep sea diving. She make the first stop on her descent at 25 meters below the surface of the water. From that point she dives down further, stopping every 5 meters. If she makes 4 additional stops, which number represents her position, relative to the surface of the water?
*
A 45
B 20
C -20
D -45
Jessica's position relative to the surface of the water after making 4 additional stops is 45 meters below the surface.Option(A) is correct.
What is sea diving?Divers who engage in scuba diving use breathing apparatus that is entirely independent of a surface air source. Christian J. Lambert-sen came up with the moniker "scuba," which stands for "Self-Contained Underwater Breathing Apparatus," in a 1952 trademark application.
According to question:Jessica's position relative to the surface of the water can be represented by the following arithmetic sequence:
[tex]$$25, 30, 35, 40, 45$$[/tex]
where the first term is 25 and the common difference is 5 (the distance between each stop).
To find the fifth term (her position after making 4 additional stops), we can use the formula for the nth term of an arithmetic sequence:
[tex]$$a_n = a_1 + (n-1)d$$[/tex]
where [tex]$a_1$[/tex] is the first term, d is the common difference, and n is the term number.
Plugging in the values we know, we get:
[tex]$$a_5 = 25 + (5-1)5 = 45$$[/tex]
Therefore, Jessica's position relative to the surface of the water after making 4 additional stops is 45 meters below the surface.

A pharmacist mixes 10 grams of a 15% medicine solution with 25 grams of a 10% medicine solution. Suppose we know that after she adds the x grams of pure medicine the pharmacists mixture is 25% medicine solution. Write an equation
The equation that represents the situation is (4 + x) / (10 + 25 + x) = 0.25
Let's start by finding the amount of medicine in the original mixture before adding any pure medicine.
The amount of medicine in the 10 grams of 15% solution is
0.15 × 10 = 1.5 grams
The amount of medicine in the 25 grams of 10% solution is
0.10 × 25 = 2.5 grams
So the total amount of medicine in the original mixture is,
1.5 + 2.5 = 4 grams
Now let x be the amount of pure medicine added.
The total amount of medicine in the final mixture is,
4 + x
The total amount of solution in the final mixture is,
10 + 25 + x
So the concentration of the final mixture is,
(4 + x) / (10 + 25 + x)
We know that this concentration is 25%, so we can write:
(4 + x) / (10 + 25 + x) = 0.25
This is the equation that represents the situation.

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 3 inches. The height of the cone is 18 inches.
Use π = 3.14.
What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them. Show all your work. (10 points)
Answer:
The formula for the volume of a cylinder is V = πr²h, where r is the radius and h is the height.
Given the diameter of both the cylinder and the cone is 8 inches, the radius is 8/2 = 4 inches.
The volume of the cylinder is Vcyl = π(4)²(3) = 48π cubic inches.
The formula for the volume of a cone is V = (1/3)πr²h.
The volume of the cone is Vcone = (1/3)π(4)²(18) = 96π/3 = 32π cubic inches.
Therefore, the relationship between the volume of the cylinder and the cone is that the volume of the cone is exactly two-thirds of the volume of the cylinder.
We can see this by dividing the volume of the cylinder by the volume of the cone:
Vcyl/Vcone = (48π) / (32π) = 3/2
So, the volume of the cylinder is 1.5 times greater than the volume of the cone.

for what mileages will company a charge less than company b? use for the number of miles driven, and solve your inequality for .
Company A will charge less than Company B for any mileage greater than 70 miles. For mileages less than 70 miles, Company B will be cheaper. The inequality solved is m > 70.
To determine for what mileages Company A will charge less than Company B, we can set up an inequality with m representing the number of miles driven.
Let's start by finding the total cost for each company based on the number of miles driven:
Company A: $138 (unlimited mileage)
Company B: $75 + $0.90m (where m is the number of miles driven)
To find the mileage for which Company A will charge less than Company B, we need to set up an inequality by equating the total cost for Company A to the total cost for Company B and then solving for m:
138 < 75 + 0.90m
Subtracting 75 from both sides, we get:
63 < 0.90m

The admission fee at an amusement park is $4.25 for children and $7.00 for adults. on a certain day, 303 people entered the park, and the admission fees collected totaled 1824 dollars. There are 108 children and 195 adults were admitted
Let the number of children admitted = C and the number of adults admitted = A
Total number of people admitted = 303
We can form two equations from the given information.
The first equation is to represent the number of people admitted in terms of children and adults.
So, the equation will be
C + A = 303 ------(1)
The second equation represents the total amount collected from admission fees.
So, the equation will be
4.25C + 7A = 1824 ------(2)
Multiplying equation (1) by 4.25, we get
4.25C + 4.25A = 1289.25 ------(3)
Subtracting equation (3) from equation (2), we get:
7A - 4.25A = 1824 - 1289.25
Simplifying, we get:
2.75A = 534.75
Dividing by 2.75, we get:
A = 195
Putting A = 195 in equation (1), we get:
C + 195 = 303
Simplifying, we get:
C = 108

what is the probability of getting all tails? express your answer as a simplified fraction or a decimal rounded to four decimal places.
The probability of getting all tails when flipping a coin three times can be calculated using the multiplication rule of probability. For each flip of the coin, there are two possible outcomes: heads or tails.
Assuming the coin is fair, both outcomes are equally likely, so the probability of getting tails on any one flip is 1/2.
To calculate the probability of getting all tails in three flips, we need to multiply the probabilities of getting tails on each individual flip. Since the flips are independent events (i.e. the outcome of one flip does not affect the outcome of another flip), we can simply multiply the probabilities together:P(all tails) = P(tails on first flip) x P(tails on second flip) x P(tails on third flip)
= (1/2) x (1/2) x (1/2)
= 1/8
Therefore, the probability of getting all tails when flipping a coin three times is 1/8 or 0.125 when expressed as a decimal rounded to four decimal places.

The general solution to the differential equation is then y(x) = c1cos(4x) + c2sin(4x).
Using the boundary conditions, we get:
y(0) = c1 = 1
y(L) = c1cos(4L) + c2sin(4L) = 1
Substituting c1 = 1 into the second equation, we get:
cos(4L) + c2*sin(4L) = 1
Solving for c2, we get:
c2 = (1 - cos(4L))/sin(4L)
Thus, the general solution to the differential equation that satisfies the given boundary conditions is:
y(x) = cos(4x) + (1 - cos(4L))/sin(4L)*sin(4x)
Now, we can answer the questions:
(a) To have precisely one nontrivial solution, we need the coefficients c1 and c2 to be uniquely determined. From the above expression for c2, we see that this is only possible if sin(4L) is nonzero. Thus, if sin(4L) ≠ 0, there exists precisely one nontrivial solution.
(b) If sin(4L) = 0, then c2 is undefined and we have a family of solutions that differ by a constant multiple of sin(4x). Hence, there are infinitely many solutions.
(c) There is no solution if the boundary conditions are inconsistent, i.e., if y(0) ≠ y(L) = 1.

you flip a coin 4 times and get 4 heads in a row what is the probability that the 5th coin flipped is a head
The probability of flipping a coin 4 times and getting 4 heads in a row is 0.0625, and the probability of getting a head on the 5th coin flip is 0.5.
The probability of getting a head on the 5th flip is still 50%. This is because each coin flip is an independent event, and each coin flip is not affected by the outcome of the previous coin flips. Thus, the probability of getting a head on the 5th coin flip is 0.5, regardless of the previous 4 coin flips.
To summarize, the probability of flipping a coin 4 times and getting 4 heads in a row is 0.0625, and the probability of getting a head on the 5th coin flip is 0.5.

Prove that the two triangles are congruent. Be sure to include each step in the proof.
Triangle ABC and triangle DEF are congruent, according to the Side-Angle-Side (SAS) postulate.
Congruent Sides Angles: What Are They?If the matching sides and angles of two triangles are the same length, then the triangles are said to be congruent. Congruent sides angles are what these are called.
Triangle ABC must be shown to be congruent with triangle DEF.
By demonstrating that the two triangles have a single pair of congruent sides, we can get started. We can observe that AB and DE are both 6 cm long.
The congruent angle between the two triangles can be demonstrated. As BAC and EDF are both right angles, we can see that they are equivalent.
Thus, according to the Side-Angle-Side (SAS) hypothesis Triangle ABC is consistent with triangle DEF, we can say.

data is gathered on the number of reviews for every app in the play store. the median number of reviews is 1,359 and the mean number of reviews is 453,058. what would explain the difference between these two numbers?
Answer:
The median and mean are two different measures of central tendency that provide different information about a data set. The median is the middle value in a data set, where half of the values are above and half are below. The mean, on the other hand, is the sum of all values divided by the total number of values.
In this case, the median number of reviews is much lower than the mean number of reviews, indicating that there are likely a few very high review counts that are skewing the data towards the higher end. This is because the mean is more affected by extreme values, while the median is not. It is possible that there are a few apps with an extremely large number of reviews, which are driving up the mean.
The mean number of reviews would be significantly higher than the median.
The difference between the median and mean number of reviews can be explained by the fact that some apps have very large numbers of reviews, whereas others have very few. The median is the middle value of the dataset, and does not take into account the outliers, which can have a large effect on the mean. For example, if there is one app with 1 million reviews, the mean number of reviews would be significantly higher than the median.

Find the value of x in a triangle, 142 degrees and 112 degrees
The value of x in the triangle can be found by using the fact that the sum of all angles in a triangle is 180 degrees. Simplifying the equation 142 degrees + 112 degrees + x = 180 degrees, we get x = 26 degrees.
To find the value of x in the triangle, we use the fact that the sum of all angles in a triangle is 180 degrees.
Let's call the third angle of the triangle "x".
Then, we have:
142 degrees + 112 degrees + x = 180 degrees
Simplifying this equation, we get:
x = 180 degrees - 142 degrees - 112 degrees
x = 26 degrees
Therefore, the value of x in the triangle is 26 degrees.
