The distribution of age for players of a certain professional sport is strongly skewed to the right with mean 26.8 years and standard deviation 4.2 years. consider a random sample of 4 players and a different random sample of 50 players from the population. What would be true about the sampling distributions of the sample mean ages for samples of size 4 and samples of size 50?

Answers

Answer 1

Answer:

For a random sample of 4 players, the sampling distribution of the sample mean age would have:

the mean wouldn't be close to 26.8 years, as a sample mean will be an unbiased estimator of the population mean but the sample here is far smaller than a sample of 50.

A larger standard deviation compared to the standard deviation of individual player ages (4.2 years), as the standard deviation of the sample mean decreases with larger sample sizes (i.e., the Central Limit Theorem). The standard deviation of the sample mean for a sample of 4 players can be calculated using the formula:

s_mean = s / sqrt(n)

where s is the population standard deviation (4.2 years) and n is the sample size (4).

For a random sample of 50 players, the sampling distribution of the sample mean age would have:

A mean close to 26.8 years, as the sample mean will be an unbiased sample mean for a sample of 4 players, as the standard deviation of the estimator of the population mean.

A smaller standard deviation compared to the standard deviation of the sample mean decreases with larger sample sizes (i.e., the Central Limit Theorem). The standard deviation of the sample mean for a sample of 50 players can be calculated using the formula:

s_mean = s / sqrt(n)

where s is the population standard deviation (4.2 years) and n is the sample size (50).

The side lengths of the real object will be 175 in, 150 in, and 75 in, respectively.

To determine the side lengths of the real object, we need to use the given scale factor and the side lengths of the scale drawing. The scale factor given is 5:1, which tells us that the scale drawing is 5 times smaller than the real object. Therefore, we can use this ratio to determine the side lengths of the real object. For example, if the side length of the scale drawing is 35 in, then the side length of the real object will be 5 times larger, which is 175 in. We can use this same ratio for the other side lengths of the scale drawing. The side length of the scale drawing is 30 in, so the side length of the real object will be 150 in. The side length of the scale drawing is 15 in, so the side length of the real object will be 75 in. Therefore, the side lengths of the real object will be 175 in, 150 in, and 75 in, respectively.

The wandering albatross can fly at speeds of up to 32 m/s (the speed limit on motorways!). One
albatross was found to have flown 16 250 km in 10 days.
Calculate its average speed in metres per second.

Answers

Answer:

Average speed = Total distance ÷ Total time

Average speed = 16250 km ÷ 10 days = 1625 km/day

1 km = 1000 m

1625 km = 1625 × 1000 m = 1,625,000 m

1 day = 24 hours = 24 × 60 minutes = 1440 minutes

10 days = 10 × 1440 minutes = 14400 minutes

Average speed = 1,625,000 m ÷ 14400 minutes = 113.19 m/min

1 minute = 60 seconds

Average speed = 113.19 m/min ÷ 60 seconds/min = 1.8865 m/s.

A sailor is up a mast so that her eyes are 10 meters above water. A lighthouse is 40 meters tall. From how far away will the sailor first see the lighthouse?

Answers

The sailor is 10 meters above the water and the lighthouse is 40 meters tall, so the total height between the two is 50 meters. Therefore, the sailor will first see the lighthouse from 50 meters away.

Assuming the lighthouse is directly in front of the sailor, the light from the lighthouse will reach the sailor first when the total distance between them is 50 meters. This means the sailor will first see the lighthouse from 50 meters away. In addition, the angle between the sailor and the lighthouse will be equal to the angle of the light when it reaches the sailor's eyes. The angle of the light will depend on the curvature of the earth, the height of the lighthouse, and the height of the sailor.

Assuming the lighthouse is at sea level, the angle of the light when it reaches the sailor's eyes can be calculated using the following equation:

Angle

= arcsin (50 / (2 * 6371))

Where 6371 is the radius of the earth in km.

This calculation gives an angle of 0.0058°. This means the light from the lighthouse will reach the sailor from a distance of 50 meters with an angle of 0.0058°.

Mrs. Adesso wants to take her class on a trip to either the science center or natural history museum. The science center charges $8 per student, plus a flat fee of $5 for a group tour. The natural history museum charges $5 per student, plus a flat fee of $20 for a group tour. For what number of students is the cost of the trip the same at each museum?

Answers

The number of students is the cost of the trip the same at each museum is 25

What number of students is the cost?

When we write expressions for the total cost of each field visit and set them equal, we find the solution to be the ratio of the difference in fixed cost to the difference in variable cost.

 y = 75 +7x . . . . . cost for x students to visit the science center

 y = 50 +8x . . . . cost for x students to visit the natural history museum

Subtracting the first equation from the second, we get

 0 = -25 +x

 25 = x . . . . . add 25; the number of students such that costs are equal

The cost will be the same either place for 25 students.

Here, the fixed cost difference is 75-50=25, and the variable cost difference is 8-7=1. The ratio of these costs is

 $25/($1 /student) = 25 students.

This relationship only holds when the higher fixed cost is associated with the lower variable cost. Charges are such that one place caters to larger numbers of students (science center), and one prefers fewer students (natural history museum).

Answers

Let's call the radius of the cone r. Then the slant height is 4r.

The area of the circular base is given by:
A = πr^2 = 167 cm²
So, r^2 = 167/π and r ≈ 4.55 cm.

The lateral area of the cone can be found using the formula:
A = πr * s
Where s is the slant height. Substituting in the values:
A ≈ π * 4.55 * 4 * 4.55 = 94 cm² (rounded to the nearest whole number).

The lateral area of the cone is approximately 94 cm²

Answers

The value of the definite integral of f(x) over the interval [−1, 5] is estimated to be between 36 and 42.

What do you mean by function?

A function is a mathematical concept that assigns a unique output value for each input value. It is a rule that takes in an input or set of inputs and maps it to a specific output. Functions are represented by symbols, usually denoted by a letter, such as "f".

In mathematical notation, a function is usually expressed as "f(x)" where "x" is the input and "f(x)" is the corresponding output. For example, a function could be defined as f(x) = x^2, which means that for any value of x, the function will calculate and return the square of that value.

Functions play a central role in mathematics and are used to model real-world phenomena and to study the relationships between variables. They are also used in computer programming to perform specific tasks, such as converting temperatures from Celsius to Fahrenheit or calculating the square root of a number.

Since 6≤f(x)≤7 for −1≤x≤5, we have a lower bound of 6 and an upper bound of 7 for the function over this interval. This means that, for any possible value of f(x) in the interval, we can use 6 as a lower estimate and 7 as an upper estimate for the definite integral. Hence, we have:

Lower estimate: ∫5−1 6 dx = 6(5 - (-1)) = 6(6) = 36

Upper estimate: ∫5−1 7 dx = 7(5 - (-1)) = 7(6) = 42

So, the value of the definite integral of f(x) over the interval [−1, 5] is estimated to be between 36 and 42.

In this case, the rectangle is the right triangle, and the lengths of the two shorter sides are 9 and 40 units. So we can write the equation:

-It is lost as heat.
-It is destroyed.
-We cannot tell without knowing the time frame in which the force of the brakes was applied.

Answers

Thus, the response is: B) The pavement becomes the new surface (and Earth).

How is this determined?

The law of conservation of momentum states that an object's momentum may only be transferred, not created or destroyed, and is equal to its mass times its velocity.

The momentum the car (and its contents) had before braking must go somewhere when it skids to a halt. The friction force between the tyres and the road in this instance causes it to be transferred to the pavement (and Earth). The friction force slows the car down until it comes to a stop by acting in the opposite direction of the car's speed.

may be presented in three formats that provide the set-up for solving proportions.

a. 3 : 4 (three nurses to four medical assistants)

b. 3

4

(three nurses to four medical assistants)

c. 3 is to 4 (three nurses to four medical assistants)

The relationship can represent something as simple as the 1 : 3 ratio commonly used

to mix frozen juices. We use one can of frozen juice concentrate to three cans of

water. Ratios are fractions that represent a part-to-whole relationship. Often when

we work with ratios, we use the fraction format to reduce the ratio to its simplest

form.

Ratios are always reduced to their lowest form

The ratio between the number of tablespoons of salt used and the liters of beans made is:

[tex]\frac{1/3}{3 / 4}[/tex]

=1/3 *4/ 3

=4 / 9

Fraction of a tablespoon might Tamar use =  4 / 9

express the confidence interval 33.2 % ± 5.8 % in the form of an interval: (lower bound, upper bound).

Answers

The confidence interval can be expressed as (27.4%, 38.0%).

This confidence interval can be calculated using the formula (X ± z*σ/√n), where X is the sample mean, z is the z-score that corresponds to the desired confidence level (in this case, 95%), σ is the population standard deviation, and n is the sample size.

This is calculated using the formula:

lower bound = point estimate - margin of error and

upper bound = point estimate + margin of error.

In this case, the point estimate is 33.2% and the margin of error is 5.8%.

Therefore, lower bound = 33.2% - 5.8% = 27.4% and

upper bound = 33.2% + 5.8% = 38.0%.

This means that we are 95% confidence interval that the true population proportion lies between 27.4% and 38.0%.

Answers

The mean of the given data be 0.17.

What is the difference between mean and variance?

Variance is a measure of dispersion that considers the spread of all data points in a data collection, in contrast to range and interquartile range. The standard deviation, which is just the square root of the variance, is the other often used measure of dispersion.

A measure of variability is the variance. It is determined by averaging the squared deviations from the mean. Your data set's variability is shown by its variance. The variance is greater in respect to the mean when the data are more dispersed.

Since the data are stated in the question to be evenly distributed, the mean will be determined using the formula.

Mean = a + b /2

Where, a be the minimum value and b be the maximum value

for the data: 0.15,0.16,0.17,0.18, and 0.19

The value of a = 0.15 and b = 0.19

Substitute the values in the above equation, we get

Mean = (0.15 + 0.19) /2

simplifying the above equation, we get

Mean = 0.34/2

Mean = 0.17

Therefore, the mean of the given data be 0.17.

The equation for the number of bouquets is 12B = 75 - 3 and the number of bouquets is 6.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a florist has 75 tulips with which to make bouquets. She will use 12 tulips in each bouquet. If the florist ends up with 3 tulips left.

The equation can be written as:-

12B = 75 - 3

12B = 72

B = 72 / 12

Why is "This statement is false" a paradox?

Answers

A contradiction in logic that arises when assertions of the form "This statement is false" are taken into account. If a statement is untrue, it is true if it is true; the opposite is true if a statement is false.

What is the paradox theory?

Ontologies of dualism, which consist of two seemingly incompatible components that when combined create a dynamic unity and continual change, are the basis of the paradox theory.

                      According to academic definitions, a paradox is a set of tensions that are at odds with one another, dependent upon one another, and persistent.

What is an example of a paradox?

Despite the fact that all creatures are equal, some are more equal than others. The pigs in George Orwell's Animal Farm came up with this saying, which they later used.

                         This claim is contradictory since no two things can be equally equal to one another.

Recall that |x - 1| <5 can be written as –5 < x – 1 < 5. Which of the following represents the solutions of t | x - 1 | <5?

Answers

The inequality equation is -4 < x < 6

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the modulus function be represented as A

Now , the equation will be

| x - 1 | < 5   be equation (1)

Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.The value of the modulus function is always non-negative.

So , -5 < x - 1 < 5

On simplifying the equation , we get

Adding 1 on both sides of the equation , we get

-5 + 1 < x - 1 + 1 < 5 + 1

-4 < x < 6

Hence , the number line will denote the inequality having x more than -4 and less than 6
