if Y is uniformly distributed over (0,5), what is the probability 4x2+4Yx+Y+2=0 has real roots?

The function f(t) = Bt / (1 + At^2) to have a critical point at (4, 1), the values of A and B must be A = 1/8 and B = 2. For the function y(t) = at^tln(t) to find the t-intercept in terms of a, we set y(t) = 0 and solve for t. The critical point of y(t) is at t = 1, and it is neither a local maximum nor minimum.

To find the values of A and B for f(t) = Bt / (1 + At^2) to have a critical point at (4, 1), we differentiate f(t) with respect to t and set it equal to zero. Taking the derivative, we have (1 + At^2) * B - Bt * 2At = 0. Simplifying and substituting the values (4, 1), we obtain the equations 16A - 32B = 0 and 1 + 16A = B. Solving these equations simultaneously, we find A = 1/8 and     B = 2.

For y(t) = at^tln(t), to find the t-intercept, we set y(t) equal to zero and solve for t. Setting at^tln(t) = 0, we know that either a = 0 or t = 1. However, for t > 0, we exclude t = 0. Thus, the t-intercept is t = 1.

To determine the critical point of y(t) = at^tln(t), we take the derivative and set it equal to zero. Differentiating y(t), we get y'(t) = at^tln(t) + at^(t-1)(1 + ln(t)). Setting y'(t) equal to zero, we find that at^tln(t) + at^(t-1)(1 + ln(t)) = 0. The critical point occurs at t = 1. To determine if it is a local maximum or minimum, we examine the second derivative.

The second derivative y''(t) = at^(t-1)(ln(t))^2 + 2a(t^(t-1)ln(t) - t^(t-1) + t^(t-1)/t). At t = 1, y''(1) = a(0)^2 + 2a(0 - 1 + 1) = 0. Since the second derivative is zero, the nature of the critical point cannot be determined from this information, so it is neither a local maximum nor minimum.

The p-value can be found with the F-distribution table or statistical software. If the p-value is less than or equal to α, then answer is option (a),If the p-value is greater than α, then answer is option (b).

To determine the correct statistical decision based on the given F-statistic, F (3, 12) = 2.72, we need additional information such as the significance level (α) of the hypothesis test. The significance level is a predetermined threshold that is used to assess the statistical significance of the results.

The correct decision depends on whether the calculated p-value, which quantifies the strength of evidence against the null hypothesis, is less than or equal to the significance level (α).

To find the p-value, you would need the F-distribution table or statistical software.

Once you have the p-value, you can compare it to the significance level (α) to make a decision:

If the p-value is less than or equal to α, you would reject the null hypothesis, indicating a statistically significant mean difference.

If the p-value is greater than α, you would fail to reject the null hypothesis, suggesting that there is not a statistically significant mean difference.

Therefore, without the significance level or the p-value, it is not possible to determine the correct statistical decision.

Explanation:

Find the diagram attached

First you need to get the missing side of the triangular pool using the pythagoras theorem;

Let the missing side be x

x² = 15² - 13²

x² = 225 - 169

x² = 56

x = √56

x = 7.48m

Amount of meter of fence needed is the perimeter of the triangular pool

perimeter of the triangular pool = 15 + 13 + 7.48

perimeter of the triangular pool = 35.48m

perimeter of the triangular pool = 35.5m

Hence the amount of meters of fence needed is 35.5m

Answer:

The factory should produce 166 pairs of high-grade shoes and 364 pairs of low-grade shoes for maximum profit

Step-by-step explanation:

The given parameters for the shoe production are;

The number of low grade shoes the factory produces ≥ 2 × The number of high-grade shoes produced by the factory

The maximum number of shoes the factory can produce = 500 pairs of shoes

The number of high-grade shoes the dealer calls for daily ≥ 100 pairs

The profit made per pair of high-grade shoed = Birr 2.00

The profit made per of low-grade shoes = Birr 1.00

Let 'H', represent the number of high grade shoes the factory produces and let 'L' represent he number of low-grade shoes the factory produces, we have;

L ≥ 2·H...(1)

L + H ≤ 500...(2)

H ≥ 100...(3)

Total profit, P = 2·H + L

From inequalities (1) and (2), we have;

3·H ≤ 500

H ≤ 500/3 ≈ 166

The maximum number of high-grade shoes that can be produced, H ≤ 166

Therefore, for maximum profit, the factory should produce the maximum number of high-grade shoe pairs, H = 166 pairs

The number of pairs of low grade shoes the factory should produce, L = 500 - 166 = 334 pairs

The maximum profit, P = 2 × 166 + 1 × 364 = 696

The population of a bacteria culture increases at the rate of 3 times the square root of the present population.

When the government imposes a specific tariff of $1, the prevailing price in the market increases to p^ = 5.5. We can use the demand and supply equations to find the quantity demanded and the quantity supplied at this price.

Quantity demanded: D(p) = 1100 - 50p = 1100 - 50(5.5) = 1100 - 275 = 825

Quantity supplied: S(p) = 200 + 100p = 200 + 100(5.5) = 200 + 550 = 750

At the price of p^ = 5.5, the quantity demanded is 825 cars and the quantity supplied is 750 cars. Since the quantity demanded is greater than the quantity supplied, there will be imports of cars. The quantity of imports will be the difference between the quantity demanded and the quantity supplied:

Imports = Quantity demanded - Quantity supplied = 825 - 750 = 75

Therefore, at the price of p^ = 5.5, there will be imports of 75 cars. There will be no exports of cars because the quantity demanded is greater than the quantity supplied.

The first incorrect step is step 2 because this step did not take the two signs positive and negative.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

To start, the equation has to be converted to slope-intercept form, or \(y=mx+b\). Start by subtracting x from both sides; \(x-x+2y=4\), \(2y=4-x\). Switch 4 and -x around to conform to the formula; \(2y=-x+4\). Then divide by 2 to isolate y; \(y=-\frac{1}{2}x+2 \). This is the final equation. Because the slope of a line perpendicular is always the opposite reciprocal (i.e. The opposite reciprocal of 4 is \(-\frac{1}{4} \), the opposite reciprocal of \(-\frac{1}{5} \) is 5) the opposite reciprocal of \(-\frac{1}{2} \)  is 2. So the equation of the line is \(y=2x\), and the answer is A.

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + 2y = 4 ( subtract x from both sides )

2y = - x + 4 ( divide terms by 2 )

y = - \(\frac{1}{2} \) x + 2 ← in slope- intercept form

with slope m = - \(\frac{1}{2} \)

Given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular} \) = - \(\frac{1}{m} \) = - \(\frac{1}{-\frac{1}{2} } \) = 2

Algebraic representations can take many forms, including equations, inequalities, functions, and matrices. These representations provide a powerful tool for analysing complex systems and deriving meaningful insights from them.

The algebraic representation \((x,y) (3x,3y)\) describes a dilation transformation, specifically an enlargement or stretch by a scale factor of 3 in both the x and y directions.

Step-by-step explanation:

Given that 12 people can comfortably fit in a 5 × 5 foot square

Area of square = 5²= 25 ft²

The dimension Given by : 8 feets depth on both sides along a 2 mile section signifies a rectangular area.

Area of rectangle = (length × width)

Recall :

1 mile = 5280 feets

2 miles = 5280 × 2 = 10,560 feets

Area = 8 × 10560 = 84480 sq feets

84480 / 25 = 3379.2

Estimated number of people will be :

3379.2 × 12 = 40,550.4

Hence, estimated number of people = 40,550

The number of minutes a scented candle lasts if it burns out sooner than 80% of all scented candles is 244 minutes.

When the distribution is normal, we use the z-score formula.

In a set with mean µ and standard deviation σ , the z-score of a measure X is given by:

Z = (X – µ) / σ

The Z-score shows how many standard deviations the measure is from the mean. After finding the Z-score, need to look at the z-score table and discover the p-value associated with the z-score. This p-value is the probability that the value of the measure is smaller than X, means, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

So, in this case, given that:

µ = 249, σ = 20

The number of minutes a scented candle lasts if it burns out sooner than 80% of all scented candles:

100 – 80 = 20th percentile, which is X when Z has a p-value of 0.2. So, X when Z = –0.253.

Now, put all the values into the formula:

Z = (X – µ) / σ

–0.253 = (X – 249) / 20

X – 249 = –0.253 * 20

X = 244

Hence, the candle burns for 244 minutes.
