The z score for the actor is -2.04, and the z score for the actress is 1.69. The actor had the more extreme age as their z score was further away from the mean compared to the actress.

z score for actor

z = (32 - 43.7) / 8.8 = -2.04

z score for actress

z = (53 - 34.5) / 11.2 = 1.69

Since the z score for the actor is more negative than the z score for the actress, the actor had the more extreme age.

The z score is a measure of how far a specific value is away from the mean, in terms of standard deviations. A negative z score indicates that the value is below the mean, while a positive z score indicates that the value is above the mean.

In this case, both the actor and the actress had ages that were below the mean for their respective genders. However, the actor's age was further below the mean than the actress's age. Therefore, the actor had the more extreme age.

The general solution to the differential equation dy/dx = 1/3(sin x − xy^2), y(0)=5 is: y = ±√[(sin x - e^(x/2)/25)/x], if sin x - xy^2 > 0 and y(0) = 5

To solve this differential equation, we can use separation of variables.

First, we can rearrange the equation to get dy/dx on one side and the rest on the other side:

dy/dx = 1/3(sin x − xy^2)

dy/(sin x - xy^2) = dx/3

Now we can integrate both sides:

∫dy/(sin x - xy^2) = ∫dx/3

To integrate the left side, we can use substitution. Let u = xy^2, then du/dx = y^2 + 2xy(dy/dx). Substituting these expressions into the left side gives:

∫dy/(sin x - xy^2) = ∫du/(sin x - u)

= -1/2∫d(cos x - u/sin x)

= -1/2 ln|sin x - xy^2| + C1

For the right side, we simply integrate with respect to x:

∫dx/3 = x/3 + C2

Putting these together, we get:

-1/2 ln|sin x - xy^2| = x/3 + C

To solve for y, we can exponentiate both sides:

|sin x - xy^2|^-1/2 = e^(2C/3 - x/3)

|sin x - xy^2| = 1/e^(2C/3 - x/3)

Since the absolute value of sin x - xy^2 can be either positive or negative, we need to consider both cases.

Case 1: sin x - xy^2 > 0

In this case, we have:

sin x - xy^2 = 1/e^(2C/3 - x/3)

Solving for y, we get:

y = ±√[(sin x - 1/e^(2C/3 - x/3))/x]

Note that the initial condition y(0) = 5 only applies to the positive square root. We can use this condition to solve for C:

y(0) = √(sin 0 - 1/e^(2C/3)) = √(0 - 1/e^(2C/3)) = 5

Squaring both sides and solving for C, we get:

C = 3/2 ln(1/25)

Putting this value of C back into the expression for y, we get:

y = √[(sin x - e^(x/2)/25)/x]

Case 2: sin x - xy^2 < 0

In this case, we have:

- sin x + xy^2 = 1/e^(2C/3 - x/3)

Solving for y, we get:

y = ±√[(e^(2C/3 - x/3) - sin x)/x]

Again, using the initial condition y(0) = 5 and solving for C, we get:

C = 3/2 ln(1/25) + 2/3 ln(5)

Putting this value of C back into the expression for y, we get:

y = -√[(e^(2/3 ln 5 - x/3) - sin x)/x]

So the general solution to the differential equation dy/dx = 1/3(sin x − xy^2), y(0)=5 is:

y = ±√[(sin x - e^(x/2)/25)/x], if sin x - xy^2 > 0 and y(0) = 5

y = -√[(e^(2/3 ln 5 - x/3) - sin x)/x], if sin x - xy^2 < 0 and y(0) = 5

Note that there is no solution for y when sin x - xy^2 = 0.

The p-value is option (A) 0.0500

Under the null hypothesis, the expected number of defective peaches in the sample of 400 would be:

p = 0.10 (since the null hypothesis assumes a maximum of 10% defective peaches)

n = 400

expected number of defective peaches = np = 0.10 x 400 = 40

We can then use the binomial distribution to calculate the probability of getting 50 or more defective peaches in a sample of 400, assuming that the null hypothesis is true.

P(X ≥ 50) = 1 - P(X < 50)

where X is the number of defective peaches in the sample, assuming the null hypothesis is true.

Using a binomial calculator or a statistical software, we can find:

P(X < 50) = 0.3081

Therefore,

P(X ≥ 50) = 1 - P(X < 50) = 1 - 0.3081 = 0.6919

This is the p-value of the hypothesis test. Since this is a one-tailed test , we can compare the p-value to the significance level, α. If α = 0.05, then the p-value is greater than α, which means we fail to reject the null hypothesis.

The rose gold bracelets sold by Chantel's fine jewelry store are considered price elastic, as an increase in price resulted in an apparent increase in demand and sales.

Based on the information provided, Chantel raised the price of her rose gold bracelets by $75 to cover unexpected expenses. Surprisingly, she observed an increase in sales at the higher price point. This suggests that the rose gold bracelets are price elastic.

Price elasticity of demand refers to the responsiveness of the quantity demanded to changes in price. When a product is price elastic, an increase in price leads to a proportionately larger decrease in quantity demanded, resulting in a decrease in total revenue. Conversely, a decrease in price would lead to a proportionately larger increase in quantity demanded and total revenue.

This suggests that the demand for these bracelets is relatively elastic, meaning that customers are responsive to changes in price and perceive the higher price as an indicator of increased value, exclusivity, or quality.

Several factors may contribute to this phenomenon. The rose gold bracelets may have unique design elements or craftsmanship that customers are willing to pay a higher price for.

The exact value of cscθ is (35 * √(1190)) / 1190.

To find the value of cscθ (cosecant θ) given that cosθ = 1/√35 and sinθ < 0, we can use the reciprocal relationship between sine and cosecant.

Recall that cscθ is the reciprocal of sinθ. Since sinθ is negative, we can determine its value based on the quadrant in which θ lies.

In the unit circle, the cosine is positive in the first and fourth quadrants, while the sine is negative in the third and fourth quadrants.

Given that cosθ = 1/√35 and sinθ < 0, we can conclude that θ lies in the fourth quadrant.

Using the Pythagorean identity, sinθ = √(1 - cos^2θ), we can calculate the value of sinθ:

sinθ = √(1 - (1/√35)^2)

     = √(1 - 1/35)

     = √(34/35)

     = √34 / √35

     = (√34 / √35) * (√35 / √35)     [Multiplying numerator and denominator by √35 to rationalize the denominator]

     = √(34 * 35) / 35

     = √(1190) / 35

Now, since cscθ is the reciprocal of sinθ, we have:

cscθ = 1 / sinθ

     = 1 / (√(1190) / 35)

     = 35 / √(1190)

     = (35 * √(1190)) / 1190.

When testing HA: µ > 45, if the test statistic is t = 2.052, n = 16, and the level of significance is 0.05, the p-value is 0.028.

The following information is given:-

The level of significance is 0.05-

The sample size (n) is 16-

The test statistic is 2.052

The p-value is the probability that the t-value or another statistic would be observed when the null hypothesis is true, given the data.

In this situation, the p-value is the area to the right of the test statistic in the t-distribution with (n - 1) degrees of freedom. The t-distribution is symmetric about the mean (0), so the p-value can also be calculated as the area to the left of the negative test statistic.

The p-value for a one-tailed test with a t-statistic of 2.052 and 15 degrees of freedom can be determined using a t-distribution table. Because this is a right-tailed test, the area in the right-tail with 15 degrees of freedom and a t-value of 2.052 should be looked up, giving the probability of 0.028.

The mathematicians credited with developing the mathematical models that predict population growth in each of two competing species are Rosenzweig and MacArthur(OPTION A).

These two scientists developed a theory known as the "competitive exclusion principle," which states that two species competing for the same resources cannot coexist indefinitely. Instead, one species will eventually outcompete and displace the other species.
Rosenzweig and MacArthur's model is based on the Lotka-Volterra equations, which are a set of differential equations that describe the dynamics of predator-prey relationships. They extended this model to include two competing species and developed the concept of the "ecological niche" – the specific set of environmental conditions under which a species can survive and reproduce.
Their model predicts that the two species will reach a stable equilibrium, where their populations remain relatively constant over time. However, the exact outcome of the competition depends on several factors, including the initial population sizes of the two species, the relative strengths of their ecological niches, and the availability of resources.
Overall, Rosenzweig and MacArthur's mathematical model has been influential in the field of ecology, providing a framework for understanding how competing species interact and how ecosystems evolve over time.
