Express the confidence interval 653.1 ± 130.3 in interval form.

Answers

The confidence interval form of the given question will be (783.4,522.4).

What is a confidence interval?

A confidence interval (CI) in frequentist statistics is a range of estimates for an unknown parameter. A confidence interval is calculated at a specified degree of confidence; the most popular level is 96%, but other values, such 90% or 99%, are occasionally used. The confidence level is the percentage of corresponding CIs over the long run that actually contain the parameter's true value. As an illustration, 96% of all intervals produced at the 96% level should have the parameter's actual value.

Here this question, it is given in the interval form.

Now we can find out the minimum and maximum value of the value.

Maximum value is 653.1+130.3 = 783.4

Minimum value is 653.1 - 130.3 = 522.4

So The confidence interval can be written as (783.4,522.4).

Hence the answer will be (783.4,522.4).

Complete the square to determine if the equation is a circle, quadratic (parabola) or other. Show all work and graph the circles and quadratics on a grid. A. 16^2 + 4^2 + 96 − 8 + 84 = 0

Answers

The conic equation 16 · x² + 4 · y² + 96 · x - 8 · y + 84 = 0 is equivalent to (x + 3)² / 4.75 + (y - 2)² / 19 = 1, that represents an ellipse.

How to derive the nature of a conical by algebraic means

Mathematically speaking, conics are described by quadratic equations of the form A · x² + B · y² + C · x + D · y + E = 0, where A, B, C, D, E are real coefficients of the conic.

We can infer if a conic is a circle, a parabola, an ellipse or a hyperbola by modifying the expression into its standard form by algebra properties. First, write the equation of the conic:

16 · x² + 4 · y² + 96 · x - 8 · y + 84 = 0

Second, complete the square in the equation of the previous step:

16 · (x² + 6 · x) + 4 · (y² - 2 · y) = - 84

16 · (x² + 6 · x + 9) + 4 · (y² - 2 · y + 4) = - 84 + 16 · 9 + 4 · 4

16 · (x² + 6 · x + 9) + 4 · (y² - 2 · y + 4) = 76

Third, factor the polynomial and simplify the expression until standard form is derived:

16 · (x + 3)² + 4 · (y - 2)² = 76

(x + 3)² / 4.75 + (y - 2)² / 19 = 1

What is a confidence interval for population standard deviation?

It is defined as the sampling distribution following an approximately normal distribution for a known standard deviation.

It is given that, a sample with the sample proportion of 0.4 and which of the following sizes will produce the widest 95% confidence interval.

The margin of error provides an estimate of the percentage of errors in real statistical data.

The formula for finding the MOE:

[tex]\rm MOE = Z\times \dfrac{s}{\sqrt{n}}[/tex]

Where,

Z is the z-score at the confidence interval

s is the standard deviation

n is the number of samples.

An interval is broader the bigger the margin of error.

The margin of error reduces with increasing sample size. The smallest confidence interval should be chosen if we want the widest possible interval.

Thus, the size 50 will produce the widest 95% confidence interval when estimating the population parameter.

Answers

The Speed of the plane in still air is 165 miles per hour.

What is speed?

 The rate that an object travels a certain distance is what is meant by the speed formula. The amount of distance a body moves in a certain amount of time is referred to as speed. The metric unit of speed is the m/s. For example, m/s, km/hr, miles/hr, and other units can be used to express speed.

Let x be the speed of the plane in the still air, and w be the wind speed.

Using speed formula Balancing by the time,

=> Time = Distance/ Speed

=> 420/(x+w) = 350/(x-w)

Then ,

=>420/(x+15)=350/(x-15)

=> 420(x-15)=350(x+15)

=> 420x-6300=350x+5250

=> 420x-350x=5250+6300

Possible options for each space = 5

so first digit has 5 options, second digit has 4 options , third digit has 3 options , fourth digit has 2 options and the final digit will have only 1 option left.

So total number of codes = 5 × 4 × 3 × 2 × 1 = 120 codes

if letters can be repeated

5 letter codes to be made.

Possible options for each space = 5

so first digit has 5 options, second digit has 5 options , third digit has 5options , fourth digit has 5 options and the final digit will have only 5 options also.

So total number of codes = 5 × 5 × 5× 5× 5= 3125 codes

if adjacent letters cannot be repeated

5 letter codes to be made.

Possible options for each space = 5

so first digit has 5 options, second digit has 4 options , third digit has 4 options , fourth digit has 4 options and the final digit will have only 4 options also.

Round your answer to the nearest cent, as necessary.

Answers

The total cost of the camera with sales tax included is $793.44

The listed  price of camera = $722.95

The sales tax rate = 9.75%

The amount of tax = The listed  price of camera × (The sales tax rate / 100)

The amount tax = 722.95 × (9.75 / 100)

Divide the terms first

= 722.95 × 0.0975

Multiply the terms

= $70.49

The cost of the camera including tax = The listed  price of camera + The amount tax

Riley and her children went into a movie theater and she bought $51 worth of bags of popcorn and drinks. Each bag of popcorn costs $5 and each drink costs $6. She bought twice as many drinks as bags of popcorn. Determine the number of bags of popcorn and the number of drinks that Riley bought.

Answers

Solving a system of equations we can see that she bought 3 bags of popcorn and 6 drinks.

How many bags of popcorn and drinks she bought?

We can define the two variables:

x = number of bags of popcorn.y = number of drinks.

Knowing that each bag of popcorn costs $5 and each drink costs $6, and the total cost was $51, we can write:

x*$5 + y*$6 = $51

And we also know that she bought twice as many drinks as bags of popcorn, then:

y = 2x

So we have a system of equations:

y = 2x

x*$5 + y*$6 = $51

Replacing the first equation into the second one:

x*$5 + (2x)*$6 = $51

x*$17 = $51

x = $51/$17 = 3

So she bought 3 bags of popcorn and 2*3 = 6 drinks.
