The experiment to compare the spreading rates of five different brands of yellow interior latex paint available in a particular area used 4 gallons (J = 4) of each paint.

The value of W for Tukey's procedure is:

W = q(α, 5, 20) * √(MSE/J)

where α = 0.05 is the significance level, 5 is the number of treatments, 20 is the total number of observations (4 observations per treatment), MSE = 450.8 is the mean square error, and q(α, 5, 20) is the critical value from the Studentized range distribution table.

Using the table, we find that q(α, 5, 20) = 3.365.

Substituting the values, we get:

W = 3.365 * √(450.8/4) = 21.63

The value of x would be the weight at which 90% of the athletes weigh more than x kg, which is equal to 0.9 times the total number of athletes.

Given that 90% of the athletes weigh greater than x kg, we may apply a proportion to get the value of x.

Let's assume that the variable n represents the total number of athletes. As 90% of athletes fall into this category, we can then denote the number of athletes who weigh greater than x kg as 0.9n.

We must ascertain the weight at which 90% of the athletes weigh more than x kg in order to estimate the value of x. To create a proportion, we can utilize the overall number of athletes and the proportion of those who weigh more than x kg:

\(\begin{equation}\frac{0.9n}{n} =\) (Weight more than x kg) ÷ (total number of athletes = n)

We can simplify this proportion to:

0.9 = (weight more than x kg) ÷ n

We can then solve for the weight more than x kg by multiplying both sides of the equation by n:

0.9n = weight more than x kg

As a result, the value of x would be equal to 0.9 times the total number of athletes and would be the weight at which 90% of the athletes weigh more than x kg. The distribution of weights among the athletes is assumed to be continuous and normally distributed for the sake of this calculation.

Answer: To determine how much Thomas and Candice charged to mow a lawn, we can compare their total earnings (including tips) to the number of lawns they mowed.

Thomas mowed 35 lawns and received $150 in tips. Let's denote the amount Thomas charged to mow a lawn as "x."

Total earnings for Thomas = Earnings from lawns + Tips

Total earnings for Thomas = (35 * x) + $150

Similarly, Candice mowed 30 lawns and received $275 in tips. Let's denote the amount Candice charged to mow a lawn as "y."

Total earnings for Candice = Earnings from lawns + Tips

Total earnings for Candice = (30 * y) + $275

Since both Thomas and Candice charged the same amount per lawn, we can set their total earnings equations equal to each other:

(35 * x) + $150 = (30 * y) + $275

Now, we can solve this equation to find the amount they charged per lawn.

35x + $150 = 30y + $275

Rearranging the equation:

35x - 30y = $275 - $150

35x - 30y = $125

To simplify the equation, we need to know the specific values of x and y, which are the amounts they charged per lawn. Without additional information, we cannot determine the exact values of x and y or how much they charged to mow a lawn.

smaller x value (x, y)=(-15,-8)

larger x value (x, y)=(+15,-8)

\(\sqrt{x^{2} + y^{2} } = 17\)

\(x^{2} +y^{2} = 289\)

y= -8

\(x^{2} =289-64\)

\(x^{2} =225\)

x= ±15

The points are (15, -8) and (-15, -8)

Coordinates are numerical lengths or angles that uniquely identify locations on two-dimensional (2D) surfaces or in three-dimensional (3D) space ( 3D ). Mathematics, scientists, and engineers frequently employ a variety of coordinate systems. The positions of points in 2D or 3D are defined by two or three straight-line axes known as cartesian coordinates, sometimes known as rectangular coordinates. All scales are linear, which means that they are all graduated in uniform-sized increments. The positions of points in 2D are defined by a different coordinate system called semilog coordinates. The other scale is logarithmic while the first is linear.

989 in^2

Step-by-step explanation:

The surface area of the larger cube is

SA = 5 s^2  because she will stain all the sides but the bottom one

SA = 5 * 11^2 = 5*121 = 605

The surface area of the smaller cube is

SA = 6s^2 since she will stain all sides

SA = 6* 8^2 =6*64 =384

Add both surface areas together

605+384

989

Answer:

989 square inches

Step-by-step explanation:

Let's start by finding the surface area of the bottom cube. It has six sides with side length 11, meaning that each side has area 11^2=121. Multiplying this by 5(since she's not staining the bottom), you get 605. For the second sphere, you can calculate this with the expression 6 * 8^2=384. Adding these together, you get a total surface area of 989 square inches. Hope this helps!

The image of the patient is located approximately 28.9 cm from the convex mirror.

To locate the image of a patient using a convex spherical mirror, we can use the mirror equation.

Equation:

1/f = 1/do + 1/di

where:

f is the focal length of the mirror,

do is the object distance (distance of the patient from the mirror), and

di is the image distance (distance of the image from the mirror).

Given:

The magnitude of the mirror's radius of curvature:

0.562 m (since it's a convex mirror, the radius of curvature is positive).

The object distance (distance of the patient from the mirror): do = 10.2 m.

To solve for the image distance, we need to find the focal length.

For a convex mirror, the focal length is half the magnitude of the radius of curvature, so f = 0.562 m / 2

= 0.281 m.

Now we can substitute the values into the mirror equation:

1/f = 1/do + 1/di

1/0.281 = 1/10.2 + 1/di

Simplifying the equation:

3.559 = 0.098 + 1/di

Subtracting 0.098 from both sides:

3.461 = 1/di

To find the image distance, we take the reciprocal:

di = 1/3.461

= 0.289 m

The image of the patient is located at a distance of 0.289 m from the mirror. Since the image distance is positive, it indicates that the image formed by the convex mirror is a virtual image.

Converting the image distance to centimeters, we have:

di = 0.289 m × 100 cm/m

= 28.9 cm

Therefore, the image of the patient is located approximately 28.9 cm from the convex mirror.

The answer is to find the critical value for constructing the standard deviation  80% confidence interval for the population mean magnesium concentration.


To find the critical value for the 80% confidence interval, we need to use the z-distribution since the sample size is greater than 30 and the population standard deviation is unknown.

The formula for finding the critical value is:
Critical value = z(alpha/2) * (standard deviation / sqrt(sample size))
Where alpha is the level of significance (1 - confidence level), z(alpha/2) is the z-score at alpha/2 level of the standard normal distribution, standard deviation is the sample standard deviation, and sample size is the number of samples.
Using a z-table or calculator, we can find that the z-score at the 40th percentile (80% confidence level) is 1.282.
Plugging in the values, we get:
Critical value = 1.282 * (0.0418 / sqrt(17)) ≈ 0.022
Therefore, the critical value for constructing the 80% confidence interval is approximately 0.022 (rounded to three decimal places).

Two planes depart from the Fairview airport, one traveling north at 920 km/h and the other traveling south at 990 km/h. We need to determine the time it takes for the planes to be 750 km apart.

Since the planes are moving in opposite directions, their combined speed is the sum of their individual speeds. The combined speed of the planes is 920 km/h + 990 km/h = 1910 km/h.

To determine the time it takes for the planes to be 750 km apart, we can use the distance formula = speed × time. Rearranging the formula, we have time = distance / speed.

Plugging in the values, we get time = 750 km / 1910 km/h. Calculating this, we find the time to be approximately 0.3921 hours.

To convert hours to minutes, we multiply by 60. Therefore, the planes will be 750 km apart in approximately 23.53 minutes.

The balance in the account 10 years after Jakie stopped her monthly payments, with the interest compounding quarterly at a rate of 6.9% per year, is approximately R373,185.53.

To calculate the balance in the account 10 years after Jakie stopped her monthly payments, we need to consider two periods: the period when she was making monthly payments and the period after she stopped making payments.

During the period when she was making monthly payments, the interest was compounded monthly at a rate of 6.9% per year. We can use the formula for compound interest to calculate the future value of the monthly payments. Using the formula:

Future Value = Payment * [(1 + interest rate/compounding periods)^(compounding periods * number of years) - 1] / (interest rate/compounding periods)

Plugging in the values: Payment = R4,500 , Interest rate = 6.9% = 0.069, Compounding periods = 12 (monthly)

Future Value = R4,500 * [(1 + 0.069/12)^(12 * 4) - 1] / (0.069/12)

Future Value = R280,192.52

Now, we need to calculate the balance after 10 years when the compounding periods change to quarterly. We can use the same formula for compound interest, but with a different compounding period.

Future Value = Previous Balance * (1 + interest rate/compounding periods)^(compounding periods * number of years)

Plugging in the values: Previous Balance = R280,192.52, Interest rate = 6.9% = 0.069, Compounding periods = 4 (quarterly), Number of years = 10

Future Value = R280,192.52 * (1 + 0.069/4)^(4 * 10)

Future Value = R526,618.01. Therefore, the balance in the account 10 years after Jakie stopped her monthly payments is A. R373 185,53.

Step-by-step explanation:

Since K appears to be a point in JL, we need to add the lengths JK and KL and make it equal to the length of JL

2x - 2 + x - 9 = 2x + 8

Then we can solve for x from there

2x - 2 + x - 9 = 2x + 8

3x - 11 = 2x + 8   [Combine like terms]

x - 11 = 8   [Subtract 2x from both sides of the equal sign]

x = 19   [Add 11 to both sides of the equal sign]

So now that we have the value of x, in order to solve the length of KL, we need to put in the value of x into that expression

x - 9 → 19 - 9 = 10

KL = 10
