The distribution of weight is based on a continuous random variable.

What is Continuous Random Variable?

In statistics, a continuous random variable can take on any value within a certain range, as opposed to a discrete variable, which can only take on a finite number of values.

Qualitative variables are categorical variables that do not have a numerical value, but instead represent characteristics or qualities of a population or sample.

Therefore, the weight of an offensive linesman is an example of a continuous random variable.

Step-by-step explanation:

Good ol' Pythagorean Theorem.

To find the short side of the larger triangle, we'll use this equation:

\(a^{2} +b^{2} =c^{2} \\\\9^2+b^2=10^2\\81+b^2=100\\\)

You can solve the rest on your own.

Use the same type of equation for the smaller triangle, except your b would be the hypotenuse, so that equation would look something like this:

\(3^2+x^{2} = b^2\)

Answer:

x ≈ 3.2

Step-by-step explanation:

Using Pythagoras' identity in the right triangle on the left

let third side be h , then

h² + 9² = 10²

h² + 81 = 100 ( subtract 81 from both sides )

h² = 19

Using Pythagoras' identity in the right triangle on the right

x² + 3² = h²

x² + 9 = 19 ( subtract 9 from both sides )

x² = 10 ( take the square root of both sides )

x = \(\sqrt{10}\) ≈ 3.2 ( to the nearest tenth )

Answer:

About 1 hour and 16 minutes

Step-by-step explanation:

From the problem, we can think that the distance between them is narrowing 11 km/hr (8 + 3). Therefore, after one hour the herd and the ranch hand are 3 km apart. We can then use 11 km/hr from earlier, and get the answer of 1 hour and 3/11 of an hour, which is about 1 hour and 16 minutes.

The probability sampling method in which you randomly select one of the first k elements and then select every k element thereafter is known as c. systematic sampling. Therefore, option c. systematic sampling is correct.

Systematic sampling is a probability sampling technique where the sample is chosen by selecting every kth element from the population, where k is a constant. This method is often used when the population is large and the complete list of elements is not easily available.

Stratified random sampling is a technique where the population is divided into strata or subgroups based on certain characteristics and a random sample is chosen from each stratum.

Cluster sampling involves dividing the population into clusters or groups and then selecting a random sample of clusters. The elements within each selected cluster are then included in the sample.

Convenience sampling is a non-probability sampling method where the sample is chosen based on convenience and availability. This method is often used in situations where it is difficult or expensive to obtain a random sample.

There is sufficient evidence to support the claim that the mean hic measurement for the child booster seats is less than 1000 hic, so the results suggest that all of the child booster seats meet the specified requirement.

To test the claim that the sample is from a population with a mean less than 1000 hic, we can perform a one-sample t-test.

Null hypothesis (H0): The population mean is equal to 1000 hic.

Alternative hypothesis (Ha): The population mean is less than 1000 hic.

To find the test statistic, we need to calculate the sample mean, sample standard deviation, and sample size.

Sample mean (x): (775 + 640 + 1159 + 644 + 509 + 533) / 6 = 715

Sample standard deviation (s): √[((775-715)² + (640-715)² + (1159-715)² + (644-715)² + (509-715)² + (533-715)²) / 5] = 275.01

Sample size (n): 6

The test statistic (t) is given by: t = (x - μ) / (s / √n), where μ is the hypothesized population mean.

t = (715 - 1000) / (275.01 / √6) ≈ -2.976

P-value:

Using the t-distribution with (n - 1) degrees of freedom, we can find the p-value associated with the test statistic -2.976.

From the t-distribution table the p-value is approximately 0.0156.

Since the p-value (0.0156) is less than the significance level (0.01), we reject the null hypothesis.

fe=76

def=180

cfd=284

Answer:

a=148.50

b=0.045

c=8

Step-by-step explanation:

i just took the quiz on edgeunity

All the value of variables are,

a = 148.50, b = 0.05, and c = 8

Now, For the values of a, b, and c in the table, we can use the formula for simple interest:

I = Prt

where I is the interest earned in dollars,

P is the principal in dollars,

r is the interest rate per year as a decimal, and t is the time in years.

Hence, By Using this formula, we can solve for the missing values in the table as follows:

For the first row, we have

P = 3300, r = 0.045, and t = 1.

We can plug in these values and the given value of a = into the formula to solve for a:

a = Prt

a = 3300 x 0.045 x 1

a = 148.50

Therefore, a = 148.50 for the first row.

For the second row, we have P = 3300, t = 3, and I = 445.50.

We can plug in these values and solve for r:

I = Prt

445.50 = 3300 x r x 3

r = 0.05

Therefore, b = 0.05 for the second row.

For the third row, we have P = 3300, t = 7, and I = 1039.50. We can plug in these values and solve for r:

I = Prt

1039.50 = 3300 x r x 7

r = 0.045

Therefore, c = 7 for the third row.

For the fourth row, we have P = 3300, t = c, and I = 1188.00. We can plug in these values and solve for c:

I = Prt

1188.00 = 3300 x 0.045 x c

c = 8

Therefore, c = 8 for the fourth row.

Thus, we have a = 148.50, b = 0.05, and c = 8 to complete the table.

On solving the provided inequality equation we cans ay that therefore, 60x + 45 <250 is the necessary inequality for the given situation.

An inequality in mathematics shows how two values are related in an imbalanced algebraic expression. According to inequality signals, one of the two variables on either side of the inequality may be larger than, greater than or equal to, less than, or less than or equal to another value.

If the daily cost for each crew member is $60, the daily wage for crew members is $60, and the daily cost of operations is $45; the amount paid equals the total of the wages for each crew member plus the cost of operations. In this case, let x indicate the size of the crew.

The maximum money supply with a 5% reserve requirement and a $400 initial deposit is $8,000.

To calculate the maximum total amount of money that will be in the money supply, we need to consider the money multiplier effect based on the reserve requirement.

The money multiplier is given by the formula: MM = 1 / reserve requirement.

Given that the reserve requirement is 5% (rr = 0.05), the money multiplier is MM = 1 / 0.05 = 20.

The initial deposit is $400.

To calculate the maximum total amount of money in the money supply, we multiply the initial deposit by the money multiplier:

Maximum Money Supply = Initial Deposit * Money Multiplier

= $400 * 20

= $8,000.

Therefore, the maximum total amount of money that will be in the money supply is $8,000 when the reserve requirement is 5% and all currency is deposited in banks with no excess reserves.

To make a 1 litter solution of 0.45 M K₂SO₄ using K₂SO₄ powder and water, you'll need to follow these steps:

Determine the number of moles of K₂SO₄ needed:

The molarity (M) of a solution is defined as the number of moles of solute per liter of solution. In this case, the desired molarity is 0.45 M, and the volume of the solution is 1 liter.

Moles of K₂SO₄= Molarity × Volume

= 0.45 mol/L × 1 L

= 0.45 mol

Calculate the mass of K₂SO₄ needed:

To determine the mass of K₂SO₄ required, you need to know the molar mass of K₂SO₄. The molar mass of K₂SO₄ is the sum of the atomic masses of its constituent elements: 2 potassium (K) atoms, 1 sulphur (S) atom, and 4 oxygen (O) atoms.

Molar mass of K₂SO₄ = 2 × atomic mass of K + atomic mass of S + 4 × atomic mass of O

= 2 × 39.10 g/mol + 32.07 g/mol + 4 × 16.00 g/mol

= 174.27 g/mol

Mass of K₂SO₄ = Moles × Molar mass

= 0.45 mol × 174.27 g/mol

= 78.42 g

You will need approximately 78.42 grams of K₂SO₄ powder.

Dissolve K₂SO₄ in water:

Measure out the calculated mass of K₂SO₄(approximately 78.42 grams) using a balance. Add the K₂SO₄ powder to a clean, dry container. Then, gradually add water while stirring to dissolve the powder completely. Use a graduated cylinder to measure 1 litterof water, and make sure the K₂SO₄ is fully dissolved in the water.

Adjust the final volume:

After dissolving the K₂SO₄, check the final volume. If the solution is slightly below 1 litter, you can add additional water to reach the desired volume of 1 litter. Stir the solution to ensure uniformity.

By following these steps, you will have prepared 1 litterof a 0.45 M solution of K₂SO₄ using K₂SO₄ powder and water.

No, Billy will not be able to reach the border before the cops arrive in 9 minutes.

To determine whether Billy can reach the border before the cops arrive, we need to calculate the time it would take him to cover the distance of 1.9 km.

Using the formula speed = distance / time, we can rearrange the formula to solve for time. Rearranging, we have time = distance / speed.

Given that Billy's speed is 13 km/h, we can calculate the time it would take him to cover 1.9 km.

time = 1.9 km / 13 km/h = 0.146 hours

To convert hours to minutes, we multiply by 60:

0.146 hours * 60 minutes/hour = 8.76 minutes
