A certain statistic dˆ is being used to estimate a population parameter d. The expected value of dˆ is not equal to d. What property does dˆ exhibit?.

Answers

The statistic's bias is a quality that the statistic does not display, according to the Central Limit Theorem for proportions.

Central limit theorem:

According to the central limit theorem in statistics, samples will be normally distributed and their means will be roughly equal to those of the entire population when the big sample size has a finite variance.

Given,

A certain statistic The population parameter d is being estimated using the function d. D's predicted value is not the same as D.

Find the property that does d display in this case.

According to the Central Limit Theorem, the following is true for a proportion p in an n-person sample:

Value anticipated, μ = p

Standard deviation: s = √p(1 - p) /n

Therefore,

The statistic is biased because the expected value in this case differs from the expected.

To complete the square of the quadratic function x² + 10x + 4 we need to add 21

Completing The Square

Completing the square is a method in algebra that is used to write a quadratic expression in a way such that it contains the perfect square. In simple words, we can say that completing the square is a process where consider a quadratic equation of the ax² + bx + c = 0 and change it to write it in the form a(x + p)² + q = 0. This method is generally used to find the roots of a quadratic equation.

Completing the square formula is a technique or method to convert a quadratic polynomial or equation into a perfect square with some additional constant. A quadratic expression in variable x: ax² + bx + c, where a, b and c are any real numbers but a ≠ 0, can be converted into a perfect square with some additional constant by using completing the square formula or technique

The equation given is

x² + 10x + 4 = 0

Take 4 to right side

x² + 10x = -4

rewrite in (x + a)² = b form

(x + 5)² = 21

x + 5 = ±√21

x = √21 - 5

x = -√21 - 5

A final exam in Math 160 has a mean of 73 with standard deviation 7.8. If 24 students are randomly selected, find the probability that the mean of their test scores is greater than 78. A) 0.0103 B) 0.0008 C) 0.8962 D) 0.0036

Answers

The correct answer is b that is the probability that the mean of their test scores is greater than 78 is 0.0008.

What is Probability?

The field of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number that lies between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The probability is calculated on dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas where odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

mean, μ = 73
standard deviation σ =7.8

η = 24

P (X*=78)

P( Z>3.1403)

Hence, the probability that the mean of their test scores is greater than 78 is 0.0008.

For symmetric distributions without outliers, the mean should be used to get the measure of center.

What are the Center and Spread of the data?

The spread in the data measures how far the numbers in the data set are away from the mean and the center in the data measures the standard deviation.

To determine the measure of center for symmetric distributions without outliers, one should use the mean. They should use the median to determine the measure of center in all other situations. The range is a suitable metric for determining the spread of a distribution.

However, the interquartile range should be used when using the median as the measure of center, and the standard deviation should be used when using the mean as the measure of center.

What is the rate of decay?

The reduction in radioactive nuclei per unit of time is the rate of decay, or activity, of a sample of a radioactive substance.

How is the decay rate calculated?

The rate of change is determined by the equation dN/dt = N, where is the decay constant, assuming N is the size of a population of radioactive atoms at a given time t and dN is the amount by which the population decreases in time dt.

What is the decay factor?

Exponential decay is the opposite of exponential growth; it has a constant multiplier that is less than 1 when a quantity decreases by the same amount over equal intervals of time. This quantity also referred to as the decay factor, can be written as (1-r).

From the above question

B= 7.8+10.8sin((2pi/63)t)

B=13=7.8+10.8 sin((2pi/63)t)

the volume of a gas in a container varies inversely with the pressure on the gas. if a gas has a volume of 500 cubic inches under a pressure of 14 pounds per square inch, what will be its volume if the pressure is increased to 19 pounds per square inch? (round off your answer to the nearest cubic inch.)

Answers

If the pressure is increased to 19 pounds per square inch, then the volume is 368.42 cubic inches

The volume of the gas = 500 cubic inches

The pressure = 14 pounds per square inch

The volume of a gas in a container varies inversely proportional with the pressure on the gas.

V ∝ 1/P

Where V is the volume and P is the pressure

Then,

V = k/P

Where k is the constant

500  = k/14

k = 500 × 14

k = 7000

The pressure of the gas = 19 pounds per square inch

Volume = 7000 /19

The percentage of 39/100 can be written as 39% as given in the question.

What is meant by percentage?

A percentage is a figure or ratio stated as a fraction of 100. The abbreviations "pct.", "pct," and "pct" are also used. A% is a dimensionless (pure) number with no unit of measurement.

The word "percent" comes from the Latin per centum, which means "hundred" or "by the hundredth." The symbol for "percent" emerged gradually from the Italian expression per cento. The "cento" symbol was developed from two circles divided by a horizontal line.

As money denominations expanded in the Middle Ages, computations with a denominator of 100 were increasingly prevalent, to the point where it became normal for mathematics texts to incorporate such computations from the late 15th to the early 16th centuries

Write the equation of the line that passes through the points (2, 7) and (5,-2).

Answers

Answer:

y = -3x + 13

Step-by-step explanation:

Assuming the line is linear, you can use the point-slope equation of a line.

(y - y) = m (x - x)

The y and x variables come from the points on the line. Points are written in the form (x, y). In the point (2,7), 2 is x and 7 is y.

1. Plug your points in.

(7 - - 2) = m (2 - 5)

2. Solve for m (the slope)

(7 + 2) = m (2 - 5)

(9) = m (-3)

9 = -3m

m = -3

3. Write an equation of the line with the slope you found.

You can write this equation in different forms, but I'll use the slope-intercept form.

y = mx + b

You'll have to find b, the y-intercept. You can plug one of your points in for x and y as well as your slope, m, and solve for b.

7 = -3(2) + b

7 = -6 + b

b = 13

Therefore, the equation is y = -3x + 13

The answer is y=-3x+13

Observe the following triangle ABC, in which we have BC² = AB² + AC2​². Here, ​​​​AB is the base, AC is the altitude (height), and BC is the hypotenuse. It is to be noted that the hypotenuse is the longest side of a right-angled triangle.

In this case, for the triangle to be true,

Answers

The conversion factor you should use to adjust your recipe for the new amount is 6.

What is conversion factor?

A conversion factor is a number that is used to multiply or divide one set of units into another. If a conversion is required, it must be done using the correct conversion factor to get an identical value.

Equating the conversion factor :

Given: original serving = 50                        8-ounce serving            

required new serving = 200                     12-ounce serving

To find: conversion factor?

Original serving = 50×8 ounce = 400 ounce

Required serving = 200×12 ounce                          

 = 2400 ounce

As we know, conversion factor = {Required Yield} ÷ {Original Yield}

∴ Conversion factor =2400 ÷ 400

∴  Conversion factor = 6

Conversion factor is greater than 1 when required yield is supposed to be greater than original yield and conversion factor is less than 1 when required yield is less than original yield.
