The first (or the only) critical coordinate is at x₁ = 1 + √2, and the corresponding value of y is (3 + 2√2) e⁻ˣ.
The second critical coordinate is at x₂ = 1 – √2, and the corresponding value of y is (3 – 2√2) e⁻ˣ.
Given function is y = (x² + 1) e⁻ˣ. To determine the critical coordinates (turning points/extreme values) of this function, we need to differentiate it.
So, the first step is to find the derivative of the given function using the product rule.The derivative of the given function is y′ = [(x² + 1) e⁻ˣ]'
= (x² + 1)' e⁻ˣ + (x² + 1) (e⁻ˣ)'
= 2xe⁻ˣ + e⁻ˣ(1 – x²)
= e⁻ˣ(2x + 1 – x²)
To find the critical coordinates, we need to set the derivative equal to zero.
Therefore, e⁻ˣ(2x + 1 – x²) = 0
⇒ 2x + 1 – x² = 0
⇒ x² – 2x – 1 = 0
Solving the above equation using the quadratic formula, we get
x₁ = 1 + √2 ≈ 2.4142 and x₂ = 1 – √2 ≈ -0.4142
So, the critical coordinates are (1 + √2, y(1 + √2)) and (1 – √2, y(1 – √2)).
Now, we need to find the corresponding values of y at these critical coordinates.
So, y(1 + √2) = (1 + √2)² e⁻ˣˡⁿ(1 + √2) = (3 + 2√2) e⁻ˣ.
Similarly, y(1 – √2) = (1 – √2)² e⁻ˣˡⁿ(1 – √2)
= (3 – 2√2) e⁻ˣ.
So, the critical coordinates are (1 + √2, (3 + 2√2) e⁻ˣ) and (1 – √2, (3 – 2√2) e⁻ˣ).
Therefore, the first (or the only) critical coordinate is at x₁ = 1 + √2, and the corresponding value of y is (3 + 2√2) e⁻ˣ.
The second critical coordinate is at x₂ = 1 – √2, and the corresponding value of y is (3 – 2√2) e⁻ˣ.

A. 0.133
B. 0.003
C 0.240
D 0.121
The probability that the archer gets exactly 4 bullseyes is 0.133.
How do we calculate?The probability of an event is described as a number that indicates how likely the event is to occur and is expressed as a number in the range from 0 and 1.
P(X = k) = C(n, k) * [tex]P^k[/tex] * [tex](1 - p)^(^n^ - ^k^)[/tex]
C(n, k) = binomial coefficient
p= probability of success in a single trial
n = number of trials
The archer hits the bullseye 59% of the time,
p = 0.59
k = 4.
n = 8)
P(X = 4) = C(8, 4) *[tex]0.59^4[/tex] *[tex](1 - 0.59)^(^8^ -^ 4^)[/tex]

Question 1 5 pts When adjusting the cutoff threshold for a classification algorithm, it is always possible to simultaneously improve the specificity and sensitivity of the classifier. O True False
The statement as it has been written can be shown as false.
Is it true or false?There is often a trade-off between specificity and sensitivity when changing the cutoff criterion for a classification algorithm. Sensitivity relates to the classifier's capacity to accurately identify the positive cases, while specificity refers to the classifier's capacity to do so.
You can modify the ratio of true positive to false positive rates by setting the cutoff value. By identifying more occurrences as positive, lowering the threshold may boost sensitivity, but it can also result in an increase in false positives, which lowers specificity.

In the diagram of EHG below, JF || HG, EJ=3, JH=18, and FG=72. What is the length of EG
Answer:
EG = 84
Step-by-step explanation:
Here, we want to get the length of EG
Mathematically, we will be considering two triangles
these are EFJ and EHG
These two triangles are similar as can be seen
when two triangles are similar, the ratio of their corresponding sides are equal
Thus, we have it that;
EH/EG = EJ/EF
let us represent EF by x
so; EG is (x + 72)
EH = 3 + 18 = 21
Hence, we have it that;
21/x+ 72 = 3/x
21(x) = 3(x + 72)
21x = 3x + 216
21x-3x = 216
18x = 216
x = 216/18
x = 12
EG = 12 + 72 from EG = x + 72
EG = 84
S2 are nonzero subspaces, with Si contained inside S2, and suppose that dim(S2) = 4 .(1) What are the possible dimensions of S1? (2) If S1 ≠S2, then what are the possible dimensions of S1 ?
The possible dimensions of S1, can range from 0 to 4, and if S1 ≠ S2, then the possible dimensions of S1 can range from 1 to 4, where the dimension of S1 is equal to the dimension of S2 plus 1 up to a maximum dimension of 4.
(1) The possible dimensions of S1, when S2 is a nonzero subspace contained inside it and dim(S2) = 4, can be any integer value from 0 to 4.
(2) If S1 ≠ S2, then the possible dimensions of S1 can range from 1 to 4. Since S1 ≠ S2, it means that S1 must have at least one additional vector that is not present in S2. Therefore, the dimension of S1 can be equal to the dimension of S2 plus 1 (dim(S2) + 1), up to the maximum possible dimension of 4.
To elaborate further, when S1 ≠ S2, it implies that there exists a vector in S1 that is not in S2. This additional vector increases the dimension of S1 by one. Hence, the possible dimensions of S1 can be 1, 2, 3, or 4, as long as it is greater than or equal to the dimension of S2 plus 1. However, it is important to note that the specific dimension of S1 depends on the specific vectors and subspaces involved in the given context.

able 29-4 Bank of Cheerton Assets Liabilities Reserves $4,200 Deposits 55,800 $60,000 Loans Refer to Table 29-4. If the Fed's reserve requirement is 5 percent, then what quantity of excess reserves does the Bank of Cheerton now hold? $1,200 $600 $2,090 $3,000
The Bank of Cheerton now holds $1,200 in excess reserves. So, correct option is A.
To determine the quantity of excess reserves that the Bank of Cheerton holds, we first need to calculate the required reserves. The required reserves are the portion of the deposits that the bank is required to hold as reserves based on the reserve requirement set by the Federal Reserve.
The reserve requirement is given as 5 percent, and the Bank of Cheerton has deposits of $60,000. Therefore, the required reserves can be calculated as follows:
Required Reserves = Deposits * Reserve Requirement
= $60,000 * 0.05
= $3,000
Next, we can calculate the excess reserves, which are the reserves held by the bank in excess of the required reserves. Excess reserves can be calculated as the difference between the total reserves (reserves held by the bank) and the required reserves:
Excess Reserves = Reserves - Required Reserves
= $4,200 - $3,000
= $1,200
Therefore, correct option is A.

In a study of the fertility of married women, conducted by Martin O'Connell and Carolyn C. Rogers for the Census Bureau in 1979, two groups of married women between the ages of 25 and 29 were randomly selected and without children, and each was asked if she planned to have a child at some point. A group of women married less than two years and another of women married five years were selected. Suppose that 240 of 290 women married less than two years plan to have a child someday, compared to 292 of 400 women married five years. We can conclude that the proportion of women married less than two years who plan to have a child children is significantly greater than the proportion of women married for five years who also plan to have children? Use a p-value.
The appropriate null hypothesis for this study is that there is no significant difference in the proportion of women married less than two years who plan to have children someday and the proportion of women married five years who plan to have children someday.
The alternative hypothesis states that there is a significant difference in the proportion of women married less than two years who plan to have children someday and the proportion of women married five years who plan to have children someday.
The hypothesis can be expressed in terms of population proportions as follows:H0: p1 = p2 (there is no significant difference in the proportion of women married less than two years who plan to have children someday and the proportion of women married five years who plan to have children someday)p1 - proportion of women married less than two years who plan to have children someday.

Answer:
The diameter is 8.6cm
Step-by-step explanation:
Given
Shape: Sphere
[tex]Volume = 332cm^3[/tex]

Substitute: [tex]Volume = 332cm^3[/tex]
[tex]332= \frac{4}{3} \pi r^3\\[/tex]

there are 24 marbles in a bag: 2/16 of the marbles are red, 1/8 of the marbles are blue, 1/4 of the marbles are yellow, 1/3 of the marbles are black, 1/6 of the marbles are silver. how many of each type of marble is there?
Answer: 3 red marbles, 3 blue marbles, 6 yellow marbles, 8 black marbles, 4 silver marbles
Step-by-step explanation:
I know these are the correct number of marbles because I set up these numbers as fractions and solved for x.
For examples, 2/16 of the marbles are red. 2/16=x/24
You would do this because we are trying to find the number of marbles that are red out of the 24 marbles.
Next, we would do 24 divided by 16= 1.5 Then 1.5 times 2=3
You would follow this rule for each fraction of marbles in order to find the true number of marbles out of 24.
