To determine if the mean weights differ between baby boys and girls, we need to state the appropriate null and alternative hypotheses.

Null hypothesis (H0): The mean weight of baby boys (μ1) is equal to the mean weight of baby girls (μ2)).

Alternative hypothesis (H1): The mean weight of baby boys (μ1) is not equal to the mean weight of baby girls (μ2)

Since we are comparing the means of two independent samples, this is a two-sample t-test. The null hypothesis assumes that there is no difference in the mean weights between baby boys and girls. The alternative hypothesis suggests that there is a difference.

In this case, we will use the P-value method with a significance level of α = 0.10 to determine if there is enough evidence to reject the null hypothesis. The P-value is the probability of obtaining a test statistic as extreme as the observed one, assuming that the null hypothesis is true.

To perform the two-sample t-test and calculate the P-value, we can use statistical software like Excel or a statistical calculator. We will need the sample weights for boys and girls.

The given data are as follows:

Boys: 7.6, 6.4, 8.1, 7.9, 8.3, 7.3, 6.4, 8.4, 8.5, 6.9, 6.3, 7.4, 7.8, 7.5, 6.9, 7.8, 8.6, 7.7, 7.4

By performing the two-sample t-test and calculating the P-value, we can determine if there is enough evidence to conclude that the mean weights differ between baby boys and girls.

Here are the null and alternate hypotheses that would be suitable for this case:

Null Hypothesis, H0: µ1 = µ2

Alternate Hypothesis, H1: µ1 ≠ µ2

A chord is a line segment joining two points on a circumference. If two different chords share one of their extremes then they form an angle known as an inscribed angle. The other extremes of these chords form an arc that is known as the intercepted arc of the inscribed angle. For example, in the picture you'll notice that chords AD and DB form the angle ADB and its intercepted arc is arcAB. The measure of an inscribed angle is half the aperture of its intercepted arc so we get:

Angle ACB also has arcAB as its intercepted arc. This means that we also have:

So angles ACB and ADB are congruent since they have the same measure. So as you can see, if two inscribed angles have the same intercepted arc they are congruent.

Angles CAD and CBD also share the same intercepted arc, arcCD. This means that this angles are also congruent.

ADB and CAD are not congruent because their intercepted arcs (arcAB and arcDC) are not the same. The same happens with BCA and CBA since their intercepted arcs are arcAB and arcBC.

The last pair of angles that we must analyze is the one composed by DEA and CEB. These two angles are formed at the intersection between two line segments. At this type of intersections four angles are formed with consecutive angles being supplementary and opposite angles being congruent. DEA and CEB are opposite angles since they share their vertex but not their sides. Therefore DEA and CEB are congruent.

Then the correct options are A, C and D.

If \(x^{2}\) ≡ n (mod 65) has a solution, then so does \(x^{2}\) ≡ -n (mod 65).

Let \(x^{2}\) ≡ n (mod 65). By definition, there exists an integer k such that\(x^{2}\) = n + 65k. Now, we want to prove that \(x^{2}\)≡ -n (mod 65) has a solution.

We know that 65 is an even number, therefore\(-1^{2}\) ≡ 1 (mod 65).

Therefore, (-1)\(x^{2}\) ≡ -n (mod 65).

Now, multiplying both sides of the equation \(x^{2}\)= n + 65k by (-1) yields (-1)\(x^{2}\) = -n - 65k.Adding 65k to both sides, we have (-1)\(x^{2}\)+ 65k = -n.

Therefore, (-1)\(x^{2}\)≡ -n (mod 65).If \(x^{2}\) ≡ n (mod 65) has a solution, then so does\(x^{2}\) ≡ -n (mod 65).

In summary , Converges, Diverges, Converges and Converges

Let's analyze each series using the comparison test to determine if they converge or diverge.

∑ (1/4^(n-1))
To apply the comparison test, we compare the series to the geometric series ∑ (1/4^n) with a common ratio of 1/4.
Since 1/4^(n-1) = (1/4^n) * (4^1), and the geometric series ∑ (1/4^n) converges (it is a geometric series with a common ratio less than 1), we can conclude that the given series also converges.

∑ (n/(3n+4))
To apply the comparison test, we compare the series to the series ∑ (n/n) = ∑ 1, which is a divergent series.
Since the given series has a term that is greater than or equal to 1/n for all n, we can conclude that the given series also diverges.

∑ (9/(6^n * 5^(3n)))
To apply the comparison test, we compare the series to the series ∑ (1/(5^n)), which is a geometric series with a common ratio of 1/5.
Since (9/(6^n * 5^(3n))) ≤ (1/(5^n)) for all n, and the geometric series ∑ (1/(5^n)) converges, we can conclude that the given series also converges.

∑ (sin(n) * cos(n))/(7^n)
To apply the comparison test, we compare the series to the series ∑ (1/7^n), which is a geometric series with a common ratio of 1/7.

After the stock-split Vilma will hold 1125 shares at $54.96 per share.

A stock split happens when a company increases the number of its shares to boost the stock's liquidity. Although the number of shares outstanding increases by a specific multiple, the total dollar value of all shares outstanding remains the same because a split does not fundamentally change the company's value.

The most common split ratios are 2-for-1 or 3-for-1 (sometimes denoted as 2:1 or 3:1). This means for every share held before the split, each stockholder will have two or three shares, respectively, after the split.

The stock split ratio for Torchmark is given as 3 for 2.

Therefore the number of shares Vilma will hold is given by:

750 × (3/2) = 1125 shares

The cost of each share :

$82.44 × (2/3) = $ 54.96

The mathematical expression y(x,t) = Asin(kx)sin(wt) provides a way to describe the behavior of a standing wave in terms of its amplitude, frequency, and location along the string.

At time t=0,

the standing wave can be mathematically expressed as

y(x,0) = Asin(kx)sin(w*0) = Asin(kx)sin(0) = 0.

This means that the displacement of the string is zero at time t=0.

However, it is important to note that this does not mean that the string is not moving at all. Rather, it means that the string is in a state of equilibrium at time t=0, with the maximum transverse displacement being A.

As time progresses, the standing wave will oscillate between the maximum positive and negative transverse displacement values, creating a pattern of nodes (points of zero displacements) and antinodes (points of maximum displacement).

The wave number k and angular frequency w are both constants that are dependent on the physical properties of the string and the conditions under which the wave is being produced.

Based on the differential equation a) Solving the DE subject to P(0) = P0 will yield P = ((kP0 - h)e^(kt) + h)/k. b) For the three cases given (P0 > h/k, P0 = h/k, P0 = 0), the behavior of the population P(t) is will be population will grow without bound, the population will remain constant, and the population will decrease and approach zero as t approaches infinity respectively. c) The fish population will go extinct in finite time if there exists a time T > 0 such that P(T) = 0. At T = (1/k)ln(-h/(kP0 - h)) the fish population will go extinct.

(a) To solve the differential equation (dP/dt) = kP - h subject to P(0) = P0, we need to separate the variables and integrate both sides:

(dP/dt) = kP - h

dP/(kP - h) = dt

∫dP/(kP - h) = ∫dt

ln|kP - h| = kt + C

kP - h = e^(kt + C)

P = (e^(kt + C) + h)/k

Using the initial condition P(0) = P0, we can solve for C:

P0 = (e^(k*0 + C) + h)/k

P0 = (e^C + h)/k

e^C = kP0 - h

C = ln(kP0 - h)

Substituting back into the equation for P, we get:

P = (e^(kt + ln(kP0 - h)) + h)/k

P = ((kP0 - h)e^(kt) + h)/k

This is the solution to the differential equation subject to the initial condition P(0) = P0.

(b) The behavior of the population P(t) for increasing time depends on the initial condition P0:

- If P0 > h/k, then the term (kP0 - h)e^(kt) will be positive and will increase exponentially as t increases, so the population will grow without bound.

- If P0 = h/k, then the term (kP0 - h)e^(kt) will be zero and the population will remain constant at P = h/k for all time.

- If P0 < h/k, then the term (kP0 - h)e^(kt) will be negative and will decrease exponentially as t increases, so the population will decrease and approach zero as t approaches infinity.

(c) The fish population will go extinct in finite time if there exists a time T > 0 such that P(T) = 0. From the equation for P, we can see that this will happen if and only if P0 < h/k:

P(T) = ((kP0 - h)e^(kT) + h)/k = 0

(kP0 - h)e^(kT) = -h

e^(kT) = -h/(kP0 - h)

Since the exponential function is always positive, this equation has no solution for P0 > h/k or P0 = h/k. However, if P0 < h/k, then the term (kP0 - h) is negative and the equation has a solution:

kT = ln(-h/(kP0 - h))

T = (1/k)ln(-h/(kP0 - h))

This is the time at which the fish population will go extinct.
