5x - 5 = 180

5x=185

185/5

x=37

41. 90 + 8x - 1 + 4x+7 =180

8x-1+4x+7=90

12x+6=90

12x=84

84/12

x=7

Step-by-step explanation:

The Laplace transform of the given function f(t) = {0, 0 < t < 1, t², t ≥ 1} is 2s⁻³.

Given the function f(t) = {0, 0 < t < 1, t², t ≥ 1}, we need to find its Laplace transform. The Laplace transform of a function f(t) is denoted by F(s) and is defined as follows:

F(s) = L{f(t)} = ∫[0,∞) f(t)e⁻ᵃˣdt,

where s is a complex variable.

To find the Laplace transform of the given function, we need to split the function into two parts: one for 0 < t < 1 and another for t ≥ 1. For 0 < t < 1, f(t) = 0, so the integral becomes:

L{0} = ∫ 0e⁻ᵃˣdt = 0.

For t ≥ 1, f(t) = t², so the integral becomes:

L{t²} = ∫ t²e⁻ᵃˣdt.

To evaluate this integral, we can use integration by parts. Let u = t² and dv = e⁻ᵃˣdt, then du/dt = 2t and v = (-1/s) e⁻ᵃˣ. Using the integration by parts formula, we get:

L{t²} = ∫ t²e⁻ᵃˣdt = (-t²/s)e⁻ᵃˣ∣∣∣[0,∞) + (2/s)∫[0,∞) te⁻ᵃˣdt.

The first term in the above equation evaluates to zero because e⁻ᵃˣapproaches zero as t approaches infinity. Using integration by parts again for the second term, we get:

L{t²} = (-t²/s)e⁻ᵃˣ∣∣∣[0,∞) + (2/s)(-t/s)e⁻ᵃˣ∣∣∣[0,∞) + (2/s²)∫[0,∞) e⁻ᵃˣdt.

The first two terms in the above equation evaluate to zero for the same reason as before. The integral in the last term evaluates to (1/s²), so we get:

L{t²} = 2/s³.

Therefore, the Laplace transform of the given function f(t) is:

L{f(t)} = L{0} + L{t²} = 0 + 2/s³ = 2s⁻³.

The number of expected double crossover progeny when multiply by the total number of progeny is 47.

When chromosomal pieces are swapped out twice, it is known as a double crossover. In the case of a double crossing, the two ends of the chromosome are still parental, but another sister chromatid sequence has "swapped" into the space between the crossovers;

When homologous chromosomes are combined, crossovers happen.

Chromatids from various chromosomes can be aligned. Exchange chromatids from, for example, segments a collision between two identical chromosomes occurs at an similar spot along their respective lengths. they are After swapping the segments, the chromatids have split between the point of contact and the chromatids' tips.

We have,

number of double crossovers is 0.305 x 0.155 x 1000

so 0.305 x 0.155 x 1000 = 47

So number of expected double crossover progeny is 47.

Test cross:

When P is true, and Q is false, the proposition P ⊃ Q is false. Therefore, the answer is TFTT. The correct answer is option d. TFTT.

The given truth table for the compound proposition P ⊃ Q is: P Q P⊃QT T T T T F FT F T T F

The conditional P ⊃ Q implies that whenever the antecedent P is true, then the consequent Q is true as well.

This implies that the only time the conditional P ⊃ Q is false is when the antecedent is true, but the consequent is false.

Since we see in the truth table that when P is true, and Q is true, the proposition P ⊃ Q is also true.

However, when P is true, and Q is false, the proposition P ⊃ Q is false. Therefore, the answer is TFTT.

Step-by-step explanation:

The number of hours when the prices of the two stocks would be the same is 3 hours.

The first step is to determine the price of stock A at noon.

Price of stock A = price at 9am + (rate x number of hours until noon)

$13.96 + (0.06 x 3)

$13.96 + 0.18

= $14.14

Change in price of stock B = price at noon - (rate x hours)

$14.71 - (0.13 x h)

= $14.71 - 0.13h

Change in price of stock A after noon = $14.14 + 0.06h

When the two stocks would be the same, the two equations would be equal:

$14.71 - 0.13h = $14.14 + 0.06h

Combine similar terms:

$14.71 - 14.14 = 0.13h + 0.06 h

Add similar terms together:

0.57 = 0.19h

Divide both sides of the equation by 0.18

h = 0.57 / 0.19

h = 3 hours

The equation of the line in slope-intercept form is y = 6x + 55.

Equations can involve variables, which are placeholders for unknown values that we wish to find. For example, the equation x + 3 = 7 asserts that the value of x plus 3 is equal to 7. We can solve for x by subtracting 3 from both sides of the equation, obtaining x = 4.

Equations can be linear or nonlinear, and they can involve one or more variables. They can be represented in various forms, such as standard form, slope-intercept form, or quadratic form.

To find the equation of the line in point-slope form, we need to first find the slope of the line. We can use any two points from the table to find the slope using the formula:

slope = (change in y)/(change in x)

Let's use the first and last points in the table:

slope = (295 - 175)/(40 - 20) = 120/20 = 6

Now we can use the point-slope form of the equation of a line:

y - y1 = m(x - x1)

where m is the slope and (x1, y1) is any point on the line. Let's use the first point (20, 175):

y - 175 = 6(x - 20)

To write this equation in slope-intercept form, we need to isolate y:

y - 175 = 6x - 120

y = 6x + 55

So the equation of the line in slope-intercept form is y = 6x + 55.

The more precise estimator ẏ₁ is the most efficient in estimating the average salary. With given values, the confidence interval is calculated to determine whether to accept the claim of a $50,000 mean salary.



In this scenario, we have two estimators for the average salary: ẏ₁, which uses precise data, and ẏ₂, which includes less precise data. The efficiency of the estimators depends on the variance of the data. If we compare the variances, Var(ẏ₁) = 0% and Var(ẏ₂) = o²(1 + 3c). Since Var(ẏ₁) is zero, it implies that ẏ₁ is the most efficient estimator. The answer does not depend on the value of c.

In the second part, with c = 0, we have Var(Y) = o². Given N = 300, s² = 20,000,000, and ẏ₁ = $48,000, we can use these values to construct a confidence interval. Using a 1% significance level, the critical value is 2.57 (from the standard normal distribution). The confidence interval is given by ẏ₁ ± 2.57 * sqrt(s²/N), which results in $48,000 ± 2.57 * sqrt(20,000,000/300). If this interval contains $50,000, we would accept your friend's claim; otherwise, we would reject it.

The given quadratic equation has no real solutions.

Given expression is 3x² + 7x = 10, and the solution to the quadratic equation using the quadratic formula is required.

Let us solve it as follows:

Step 1: Identify the values of a, b, and c. Here, a = 3, b = 7, and c = 10.

Therefore, we have: a = 3, b = 7, c = 10

Step 2: Plug in the values of a, b, and c in the quadratic formula \(X = [-b \pm \sqrt{(b^{2} -4ac)]/2a. }\)

We get X = [-7 ± √(7²-4(3)(10))]/(2×3)

Step 3: Simplify the equation obtained in Step 2.

We get\(X = [-7 \pm \sqrt{(49-120)]/6} = [-7 \pm \sqrt{(-71)]/6}\ ]\)

Now, we cannot have the square root of a negative number since the square of any real number is always positive.

Therefore, the given quadratic equation has no real solution.
