The hypothesis; greater fraction of kinetic energy is lost from the system during the collision when the speed of the first cart is greater is; Correct
What is the Hypothesis of the Collision?In an Inelastic Collision, energy is not conserved . Now, the loss of energy could be in the form of friction, vibrational energy, sound, heat energy, e.tc.
Now, for example frictional energy is proportional to the velocity. The, the greater the velocity, the greater the loss of energy. This is also true about vibrational energy, sound, heat energy, e.tc.
Thus, we can conclude that the hypothesis is correct.

Explanation:
stocks x and y have the following data. assuming the stock market is efficient and the stocks are in equilibrium, which of the following statements is correct?
The correct statement is these two stocks must have the same dividend yield.
What is the dividend yield of the stock?Dividend yield of a stock is the dividend per share divided by the total market price of the stock.
Dividend yield = dividend per share / market price
Dividend per share = market value x (required return - expected growth)
Dividend per share for Stock X = $25 x (10% - 7%) = $0.75
Dividend per share for Stock Y = $40 x (12% - 9%) = $1.20
Dividend yield for Stock X = 0.75 / 25 = 0.03
Dividend yield for Stock Y = 1.20 / 40 = 0.03
Here is the complete question:
Stocks A and B have the following data. Assuming the stock market is efficient and the stocks are in equilibrium, which of the following statements is CORRECT? A B Required return 10% 12%Market price $25 $40Expected growth 7% 9%

Recall that in a 45 – 45 – 90 triangle, if the legs each measure x units, then the hypotenuse measures x units. (72π – 144) mm2 (72π – 72) mm2 (288π – 288) mm2 (288π – 144) mm2
The area of the shaded region is = (72π - 144) mm²
What is the area of a shaded region?The area of a shaded region is that enclosed part of a plane figure that is shaded.
Suppose;
A square is inscribed in a circle with a diameter of 12√2 millimeters. Everything outside of the square is shaded.Let's first find the area of the circle.
Area of circle = [tex]\mathbf{\pi r^2}[/tex]
Area of circle = [tex]\mathbf{\pi \times (\dfrac{12 \sqrt{2}}{2})^2}[/tex]
Area of circle = 72π sq mm
We know that the side of the inscribed square = [tex]\mathbf{\dfrac{12\sqrt{2}}{\sqrt{2}}}[/tex] = 12 mm
Area of the square = side(L)²
Area of the square = 12²
Area of the square = 144 sq mm
Now, the area of the shaded region can be estimated by finding the difference between the area of the square from that of the circle.
i.e.
The area of the shaded region is = (72π - 144) mm²

A quality control engineer is testing the battery life of a new smartphone. the company is advertising that the battery lasts 242424 hours on a full charge, but the engineer suspects that the battery life is actually less than that. they take a random sample of 303030 of these phones to test h_0: \mu=24h 0 :μ=24h, start subscript, 0, end subscript, colon, mu, equals, 24 hours versus h_\text{a}: \mu < 24h a :μ<24h, start subscript, start text, a, end text, end subscript, colon, mu, is less than, 24 hours, where \muμmu is the mean battery life of these phones. the sample data had a mean of 212121 hours and a standard deviation of 161616 hours. these results produced a test statistic of t\approx-1.03t≈−1.03t, approximately equals, minus, 1, point, 03 and a p-value of approximately 0.1560.1560, point, 156. assuming the conditions for inference were met, what is an appropriate conclusion at the \alpha=0.10α=0.10alpha, equals, 0, point, 10 significance level?
The appropriate conclusion of the hypotheses is that; there is insufficient evidence to support the claim that the mean battery life not up to 24 hours.
What is the Conclusion of the Hypothesis?
We are given;
Null Hypothesis; H₀: μ = 24
Alternative Hypothesis; Hₐ: μ < 24
We are aslo given that;
Significance level; α = 0.10
test statistic; t = 1.03
p-value = 0.156
Now, we see that our p-value is greater than the significance value and as such since the alternative hypothesis is the claim we will fail to reject the null hypothesis and conclude that there is insufficient evidence to support the claim that the mean battery life not up to 24 hours.

The value of WACC from the given information is about 7.4%.
What is WACC?WACC is defined as the weighted average cost of capital. It is the rate at which a firm is projected to pay all of its security holders on average to finance its assets.
The firm's cost of capital is frequently referred to as the WACC. It is important to note that the external market, not management, determines this.
The formula of WACC is:
[tex]\text{Weighted Average Cost of Capital (WACC)} = \dfrac{\text{Annual Dividend}}{\text{Sales price of Proffered Stock} - \text{Sales price} \times \text{FC}}[/tex]
According to the given information,
Annual Dividend = $8.50,
Sales price of Proffered Stock =$120.
Flotation Cost(FC) = 4%.
Now, putting the values in the formula of WACC,
[tex]\text{Weighted Average Cost of Capital (WACC)} = \dfrac{\text{Annual Dividend}}{\text{Sales price of Proffered Stock} - \text{Sales price} \times \text{FC}}\\\\\text{Weighted Average Cost of Capital (WACC)} =\dfrac{8.5}{\$120- (\$120 \times 4\%)}\\\\\text{Weighted Average Cost of Capital (WACC)} =0.074(Approx.)[/tex]

A relation that assigns to each element x from a set of inputs or ________ exactly one element in a
The complete sentence is:
"A relation that assigns to each element x from a set of inputs or domain exactly one element in a..."
How to complete the sentence?
First, let's describe what a mathematical relation is.
A relation between two variables maps the element from the set of inputs, also called the domain, into the set of outputs, also called the range.
So we have something like:
y = h(x)
Where the relation h() is mapping the element x into the element y.
Now, the sentence that we need to complete is:
"A relation that assigns to each element x from a set of inputs or ________ exactly one element in a..."
