Let f(t) be 51000+ (2100)t which represent Chelsea's salary at Company A and g(t) be 45000(1.041)t which Chelsea salary at Company B.
Chelsea's offer from company A includes a raise of $2100 annually and a starting salary of $45,000.
Since the increase is constant, the salary of Chelsea from Company A is a linear function, as can be seen here.
f(t) is salary of chelsea from company A after t years.
f(t) = 45000+ (2100)t
The offer made to Chelsea by company B includes a starting salary of $45,000 and an annual raise of 4.1%.
we can see here that raise is exponential, so raise is:
(1+4.1/100) = (1+0.041) = (1.041) per year.
Consequently, the salary of Chelsea from Company B is a function that is exponential.
g(t) is salary of chelsea from company B after t years.
g(t) = 45000(1.041)t

assume that a wild-type sequence is 5'agcctac3'. which of the following sequences might be produced by a transversion? correct!
Transversion is known as point mutation in DNA.
Transversion is a term used in molecular biology. It refers to a point mutation in DNA in which a single (two ring) purine (A or G) is changed for a (one ring) pyrimidine (T or C), or vice versa. A transversion can be spontaneous, or it can be caused by ionizing radiation or alkylating agents. It can only be reversed by a spontaneous reversion.
So, here 5'AGCCTAC3' we can replace (A or G) with (T or C)

The history of melting point data for a certain product indicates that the long-term average melting point has been 95 degrees. It is desired to test to see if the average is still 95 degrees or whether it has changed. a) Set up the statistical test at a 0.01 significance level and draw the conclusion using the sample data that follows: the average of a sample of 16 randomly chosen melting points is 94.32 degrees. Assume that the distribution of melting points is normal with σ = 1.20 . b) What is the critical region for this test, both in terms of the sample average and the z-score?
As per the desire to test to see if the average is still 95 degrees or whether it has changed. The results will be as follows:
a) The null hypothesis and the alternative hypothesis must be identified before we can set up the statistical test at a 0.01 significance level. The average melting point, which is still 95 degrees, has not altered, according to the null hypothesis. The other theory is that the average melting point, which was 95 degrees, has changed.
Next, we must establish the test's critical value. The critical value will be the amount that corresponds to a p-value of 0.01 because we are choosing a significance level of 0.01. We may use the usual normal distribution to determine the critical value because we are presuming that the melting point distribution is normally distributed with a standard deviation of 1.20.
Using the sample data, we discover that a sample of 16 melting points has an average temperature of 94.32 degrees. A one-sample z-test can be used to examine whether this sample average differs noticeably from the 95 degree long-term average.
where x is the sample average (94.32), is the long-term average (95), σ is the standard deviation of the melting points (1.20), and n is the sample size (16).
Plugging these values into the formula, we get:
z = (94.32 - 95) / (1.20 / √16) = -0.83
We are unable to rule out the null hypothesis because the z-score is smaller than the critical value. As a result, we draw the conclusion that 95 degrees still serve as the average melting point.
b) The range of values that would be deemed statistically significant at the 0.01 significance level constitutes the critical region for this test. The range of values that would be regarded as significantly different from the long-term average of 95 degrees is the critical zone in terms of the sample average. The range of values that would be associated with a p-value of less than 0.01 is known as the critical zone in terms of the z-score.
The required z-score value for a one-sided test with a significance level of 0.01 is 2.326. Therefore, any number more than 2.326 is the critical zone in terms of the z-score. This relates to a range of values that are significantly higher than 95 degrees based on the sample average.
The essential z-score values for a two-sided test with a 0.01 significance level are -2.326 and 2.326. Therefore, any value between -2.326 and 2.326 constitutes the key zone in terms of the z-score. This relates to a range of values that are significantly higher or lower than 95 degrees, based on the sample average.

Please help !
If a+b=1, prove by induction that a^3+b^3 is bigger or equal to ¼.
To prove that a^3+b^3 is bigger or equal to ¼, we can use mathematical induction. This involves two steps:
Show that the statement is true for the base case of a and b (i.e., when a and b are equal to some specific values).Assume that the statement is true for some arbitrary values of a and b (i.e., the "inductive hypothesis"). Then, show that it must also be true for the next values of a and b (i.e., a+1 and b+1).To begin, let's consider the base case where a and b are equal to 0. In this case, a^3+b^3 is equal to 0^3+0^3, which is 0. Since 0 is greater than or equal to ¼, the statement is true for the base case.
Next, we can assume that the statement is true for some arbitrary values of a and b (i.e., the inductive hypothesis). That is, we can assume that a^3+b^3 is bigger or equal to ¼.
To complete the proof, we need to show that a^3+(b+1)^3 is also bigger or equal to ¼. To do this, we can use the fact that (a+1)^3 = a^3+3a^2+3a+1. Since the inductive hypothesis states that a^3+b^3 is bigger or equal to ¼, we can say that a^3+(b+1)^3 = a^3+b^3+3a^2+3a+1 is also bigger or equal to ¼.
Therefore, by mathematical induction, we have shown that a^3+b^3 is bigger or equal to ¼ for all values of a and b.
Hans has a new aquarium. The tank is in the shape of a rectangular prism, 5 ft long, 2 ft wide, and 3 ft deep. He plans to raise fish and sell them to a local pet store. The pet store will inspect the aquarium to make sure that the fish are being kept in a healthful environment. One of the main concerns is that each fish has enough water. Hans looks up the amount of water needed for the species of fish he plans to raise. He finds the answer, but it is given in cubic inches. (a) Find the volume of water that the tank holds in cubic inches. Use the table of conversion facts, as needed. (b) The particular species Hans plans to raise requires at least 690 in. of water per fish. If there is any amount less than this, no matter how much less, the pet store will not accept Hans's fish. What is the largest whole number of fish that he can keep in the aquarium? (c) The pet store will pay $1.79 for each fish. If he fully populates his aquarium and sells all the fish, how much money will he collect?
Answer:
A) 60,480 cubic inches
B) 87 Fish
C) $155.73
Step-by-step explanation:
This will be long.
1) 5ft x 4ft x 3ft can be rewritten as 60in x 28in x 36 in.
This will get you 60,480in^3 or 60,480 cubic inches.
2) We take that 60,480 in^3 and divide it by the 690 needed per fish.
60,480 / 690 = 87.65. Since we need to make sure we can't go over, that gives us 87 fish.
3) We take that 87, and multiply it by 1.79
87 x 1.79 = $155.73

Define end behavior.The behavior of the function graph at the "ends" of the x-axis is known as the end behavior of a function, or f. In other words, if we look at the right end of the x-axis (as x approaches +∅) and the left end of the x-axis (as x approaches ∅), the end behavior of a function represents the trend of the graph. Look at the polynomial function's leading term to identify its end behavior. The leading term will dominate the graph since it has the largest power and will thus increase much more quickly than the other terms as x gets very large or very small.

10% acid content. How much of each does he need?
The quantity of 30% acid content and 10% acid content used is 0.15 liters and 1.35 liters respectively
How much of each acid content is needed?Let
30% acid content = x10% acid content = yx + y = 1.5
0.3x + 0.1y = 1.5 × 0.12
0.3x + 0.1y = 0.18
x + y = 1.5
0.3x + 0.1y = 0.18
From (1)
x = 1.5 - y
Substitute into (2)
0.3x + 0.1y = 0.18
0.3(1.5 - y) + 0.1y = 0.18
0.45 - 0.3y + 0.1y = 0.18
- 0.3y + 0.1y = 0.18 - 0.45
-0.2y = -0.27
divide both sides by -0.2
y = -0.27 / -0.2
y = 1.35
Substitute into (1)
x + y = 1.5
x + 1.35 = 1.5
x = 1.5 - 1.35
x = 0.15
Therefore, 0.15 30% acid content and 1.35 10% acid content is needed.

What is the inverse of this function f(x)=-1/2sqrtx+3, x>_-3
The inverse of the function f(x) = -1/2√x + 3, x ≥ -3 is y = (6 - 2x)²
How to determine the inverse of the functionFrom the question, we have the following parameters that can be used in our computation:
f(x)=-1/2sqrtx+3, x>_-3
Express properly
So, we have
f(x) = -1/2√x + 3, x ≥ -3
Write out the function
f(x) = -1/2√x + 3
Express as an equation
y = -1/2√x + 3
Swap x and y
This gives
x = -1/2√y + 3
Subtract 3 from both sides
-1/2√y = x - 3
So, we have
√y = 6 - 2x

If Ellie has 3 more quarters than nickels and they have a combined value of 195 cents, how many of each coin does she have?
Using system of linear equation, the number of quarter is 7 and nickel is 4
System of Linear EquationSystem of linear equations is the set of two or more linear equations involving the same variables. Here, linear equations can be defined as the equations of the first order, i.e., the highest power of the variable is 1. Linear equations can have one variable, two variables, or three variables. Thus, we can write linear equations with n number of variables.
To solve this problem, we need to write a system of linear equation.
let;
x = quartersy = nickels1 nickel = 5 cent
1 quarter = 25 cent
25x + 5y = 195 ... eq(i)
x = 3 + y ...eq(ii)
Put eq(ii) into eq(i)
25(3 + y) + 5y = 195
75 + 25y + 5y = 195
75 + 30y = 195
30y = 195 - 75
30y = 120

It is known that the probability p of tossing heads on an unbalanced coin is either 1/4 or 3/4. The coin is tossed twice and a value for Y , the number of heads, is observed. For each possible value of Y , which of the two values for p (1/4 or 3/4) maximizes the probability that Y = y? Depending on the value of y actually observed, what is the MLE of p?
On solving the provided question we can say that NILE is not unique for this case
What is Probability?Probability is the possibility or chance that something will happen. Probability = how many different paths there are to success/the total number of events that might occur. A coin flip, for instance, has a 50% chance of coming up heads since there is only one method to acquire a head and there are a total of two possible outcomes (a head or tail). P(heads) = 1/2 is the formula.
Note: the probability is equal to the mass function for Y :2
since, ML criteria, we choose p which maximizes the probability.
If Y 0, L (p) is maximized at p 0.25.
If Y 2, L (p) is maximized at p 0.75.
[tex]But if Y 1, L (p) has the same value at both as shown above; that is,[/tex]
L (0.25) L (0.75) for y — 1.

Find the solution of y = log(x + 3) and y = 1.
Answer:
x=7
Step-by-step explanation:
y = log(x + 3) and y = 1.
Substitute y =1 into the equation
1 = log(x + 3)
Raise each side to base 10 since log (x+3) has a base 10 implied
10^1 = 10^ log(x+3)
10 = x+3
Subtract 3 from each side
10-3 = x+3-3
7 =x

The equation that correctly represents the given problem is;
¹/₂p - 2 = 18
How to solve algebra word problems?We are told that p is the time it takes Tomás to bike to the park.
Now, we are given that;
Time taken by Tomás to bike to the community center = 2 minutes less than half the time it takes him to bike to the city park.
Time taken by Tomás to bike to the community center = 18 minutes
Thus, correct equation can be expressed as;
¹/₂p - 2 = 18
And if we need to solve p, we can just make p the subject of the equation and solve accordingly.
