Caterpillar nitrogen assimilation and body mass. we explored the relationship between nitrogen assimilation and body mass (both on log scales) for data on a sample of caterpillars in Caterpillars. The Instar variable in the data codes different stages (1 to 5) of caterpillar development.
a. Fit a model to predict log nitrogen assimilation (LogNassim) using log body mass (LogMass). Report the value of for this model.
b. Fit a model to predict LogNassim using appropriate indicators for the categories of Instar. Report the value of for this model and compare it to the model based on LogMass.
c. Give an interpretation (in context) for the first two coefficients of the fitted model in (b).
d. Fit a model to predict LogNassim using LogMass and appropriate indicators for Instar. Report the value of and compare it to the earlier models.
e. Is the LogMass variable really needed in the model of part (d). Does the linear trend appear to be better when the caterpillars are in a free growth period? (Again, we are not ready to fit more complicated models, but we are looking at the plot for linear trend in the two groups.)

Answers

A. Produce a scatterplot for predicting nitrogen assimilation (Nassim) based on Mass. Comment on any patterns.

b B.Produce a similar plot using the log (base 10) transformed variables, LogNassim versus Log Mass. Again, comment on any patterns.

C. Would you prefer the plot in part (a) or part (b) to predict the nitrogen assimilation of caterpillars with a linear model? Fit a linear regression model for the plot you chose and write down the prediction equation.

What is the equation for g(x)=

Answers

Answer:

g(x) = -(x + 3)^2  - 1

Step-by-step explanation:

g(x) has a peak, and goes down on both sides, it needs a negative sign.  From the vertex, when x increases by 1, y decreases by 1, and when x increases by another 1, y decreases by 3.  a = -1.  The function is 3 units to the left and 1 unit down.  That will make h = -3 and k = -1 to the function g(x) = a(x - h)^2 + k.

Determine the odds of drawing two aces if two cards are removed from
regular deck.

Answers

Answer:

The chance of drawing one of the four aces from a standard deck of 52 cards is 4/52; but the chance of drawing a second ace is only 3/51, because after we drew the first ace, there were only three aces among the remaining 51 cards. Thus, the chance of drawing an ace on each of two draws is 4/52 × 3/51, or 1/221

The income should be more than the cost in order to make a profit and that happens for Leanne when she sells 8 quilts, so the 8 should be on the x-axis (the axis named "Quilts Sold")

The income should be 0 in the beginning bc when she sells 0 quilts she will be earning 0.

after selling 8 quilts her income will be higher than her costs

(Though naming the y-axis as "profit" is not accurate bc when she sells 0 quilts she will lose money since she will be spend money to make the quilts but not earn the money to compensate for the cost).

with all of these reasons combined the correct should be the one on the bottom right

The National Survey on Drug Use and Health also reported that 21% of males in the same age group (12-20) are binge drinkers. Suppose that in addition to the 10 randomly chosen females, a random sample 10 males from the same age group is chosen (to a total of 20). Let the random variable Y be the total number of males and females (out of 20) who are binge drinkers. Which of the following is true regarding the random variable Y?
a. Y has a binomial distribution with n-60 and p.16
b. Y does not have a binomial distribution since p, the probability of being a binge drinker, is not the same for all the trials.
c. Y has a binomial distribution with n-60 and p .31
d. Y does not have a binomial distribution since the number of trials n is not fixed.
e. Y does not have a binomial distribution since the trials are not independent.

Answers

Answer:

Y does not have a binomial distribution since p, the probability of being a binge drinker, is not the same for all the trials.

Step-by-step explanation:

For a binomial distribution, condition required include :

A fixed number of trials ; Here the number of trials is 20 ; hence, this condition is met.

Each trial must be independent : yes, it is independent as a selected individual could either be a binge drinker or not. The outcome of each trial is either a success or a failure ; being a drinker or not.

However, the probability of being a binge drinker (that is probability of success) could vary for male and female. The probability of male being a binge drinker is 0.21 while that if female isn't specified, this probability, p value should be the same for all trials. Hence, with this value not being the same for all trials, the binomial probability condition is violated.

Does the function satisfy the hypotheses of the Mean Value Theorem on the given interval? f(x) = e−4x, [0, 2] Yes, it does not matter if f is continuous or differentiable; every function satisfies the Mean Value Theorem. No, f is not continuous on [0, 2]. There is not enough information to verify if this function satisfies the Mean Value Theorem. No, f is continuous on [0, 2] but not differentiable on (0, 2). Yes, f is continuous and differentiable on , so it is continuous on [0, 2] and differentiable on (0, 2) . If it satisfies the hypotheses, find all numbers c that satisfy the conclusion of the Mean Value Theorem. (Enter your answers as a comma-separated list. If it does not satisfy the hypotheses, enter DNE).

Answers

Answer:

(a) Yes, it does not matter if f is continuous or differentiable; every function satisfies the Mean Value Theorem.

(b) [tex]c =0.51995[/tex]

Step-by-step explanation:

Given

[tex]f(x) = e^{-4x};\ [0,2][/tex]

Solving (a); Does the function satisfy M.V.T on the given interval

We have:

[tex]f(x) = e^{-4x};\ [0,2][/tex]

The above function is an exponential function, and it is differentiable and continuous everywhere

Solving (b): The value of c

To do this, we use:

[tex]f'(c) = \frac{f(b) - f(a)}{b - a}[/tex]

In this case:

[tex][a,b] = [0,2][/tex]

So, we have:

[tex]f'(c) = \frac{f(2) - f(0)}{2 - 0}[/tex]

[tex]f'(c) = \frac{f(2) - f(0)}{2}[/tex]

Calculate f(2) and f(0)

[tex]f(x) = e^{-4x}[/tex]

So:

[tex]f(2) = e^{-4*2} = e^{-8} = 0.00033546262[/tex]

[tex]f(0) = e^{-4*0} = e^{0} = 1[/tex]

This gives:

[tex]f'(c) = \frac{0.00033546262 - 1}{2}[/tex]

[tex]f'(c) = \frac{-0.99966453738}{2}[/tex]

[tex]f'(c) = -0.4998[/tex]

Note that:

[tex]f'(x) = (e^{-4x})'[/tex]

[tex]f'(x) = -4e^{-4x}[/tex]

This implies that:

[tex]f'(c) = -4e^{-4c}[/tex]

So, we have:

[tex]f'(c) = -0.4998[/tex]

[tex]-4e^{-4c} =-0.4998[/tex]

Divide both sides by -4

[tex]e^{-4c} =\frac{-0.4998}{-4}[/tex]

[tex]e^{-4c} =0.12495[/tex]

Take natural logarithm of both sides

[tex]\ln(e^{-4c}) =\ln(0.12495)[/tex]

[tex]\ln(e^{-4c}) =-2.0798[/tex]

Apply law of natural logarithm

[tex]\ln(e^{ax}) =ax[/tex]

So:

[tex]-4c =-2.0798[/tex]

Solve for c

[tex]c =\frac{-2.0798}{-4}[/tex]

[tex]c =0.51995[/tex]

The Next term of sequence is  2n³ - 8.5n²+ 15.5n - 7.

What is Sequence?

A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. Similar to a set, it has members (also called elements, or terms). The length of the series is the number of elements (potentially infinite).

Given:

Sequence:1 2 6 17 47

By looking at the sequence we have the formula

t(n) = 2n³ - 8.5n²+ 15.5n - 7

So, the next term of Sequence would be

t(6)=  2(6)³ - 8.5(6)²+ 15.5(6) - 7

t(6) = 108

Hence, the next term is 108.
