Answers

Answer 1

To find the critical value that should be used in constructing the 80% confidence interval for the average amount spent by 8 to 11 year olds on a trip to the mall.

What is critical value?

the proper z-score for an 80% confidence interval must first be established. Both a z-table and a z-score calculator may be used for this.Using a z-table, i may search up the value of z such that 80% of the area under the standard normal curve is to the left of z to get the z-score. This number is around 0.84.We can then use this z-score to calculate the 80% confidence interval by taking the sample mean and adding or removing the product of the z-score and the standard error of the mean. The standard error of the mean is computed by dividing the standard deviation by the square root of the sample size.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign. Mathematical algebraic equations typically have one or more variables. More than one variable may be present in a linear equation. An equation is said to be linear if the highest power of a variable is consistently 1. Another name for it is a one-degree equation.

Sol- as per the given question y= 8x -20

We have to add the equations

(2x+10)° + (8x-20)°= 180°

= (10x-10)° = 180°

= (10x)° = 190°

What is rectangle?

A rectangle is a sort of quadrilateral with parallel sides that are equal to one another and four vertices that are all 90 degrees apart. It is also known as an equiangular quadrilateral for this reason.

                                          Because the opposite sides of a rectangle are equal and parallel, it can also be referred to as a parallelogram.

Let x = length of the side parallel to the river

     y = length of each of the other two sides

Then xy = 5,000, so y = 5,000/x

Minimize:  L = length of the fence

L = x + 2y

 = x + 10,000/x, where x > 0

L' = 1 - 10,000/x2 = (x2 - 10,000)/x2

L' = 0 when x = 100 or -100

Since x can't be negative, x must be 100.

When 0 < x < 100, L' < 0.  So, L is decreasing.

When x > 100, L' > 0.  So L is increasing.

Therefore, L has a relative and absolute minimum when x = 100 m

                                                                                    y = 5,000/x = 50 m

The possible length of the region after solving the quadratic equation is either 170ft or 50ft.

What is a quadratic equation?

A quadratic equation in algebra is any equation that can be written in the simpler form where x stands for an unknown value and a, b, and c are known quantities. The assumption is that a > 0; an equation with a = 0 is thought to be degenerate because they become linear or even simpler.

Solution Explained:
Lets assume, length = x and width = y

So we know, the area and perimeter is supposed to be 8500 and 440 respectively

we form the equations,

1) 8500 = xy , and                       [Area = length*width]

2) 440 = 2(x + y)                           [ Perimeter = 2(length +width)]

   220 = x + y

So, x = 8500/y (from equation 1) and put the value of x in 2

220 = x + (8500/x)

After solving this we get the quadratic equation,

x^2 - 220x + 8500 = 0

Solving the equation, we get

x = 170 or, x = 50 which are the two possible lengths of the region.

William bought a photocopier and supplies for $162. 50, which will allow him to make copies for $0. 12 each. A photocopy store charges $0. 21 for each copy. How many copies must william make before his total cost is less than getting copies made at the photocopy store?.

Answers

William must make 1806 copies before his total cost is less than the photocopy store.

Let William made x copies from his home photocopier.

Now total cost of x copies = 0.12 x + 162.5

Total cost of x copies from the store = 0.21 x

Now his cost needs to be lower, so we form an inequality to solve this problem.

0.12x + 162.5 < 0.21x

or, 0.12x - 0.21x < -162.5

or, -0.09x < -162.5

or, x > 1805.56

Hence the minimum value of x will be 1806.

Therefore we can say that he needs to make at least 1806 copies.

The two sides of a mathematical equation having an inequality must be equal. In inequality, we compare several values in contrast to equations. The equal sign can be substituted with the less than (or less than as well as equal to), larger above (or greater to), or is not equal to signs.

prove that for every positive integer n, there are n consecutive composite integers. [hint: consider the n consecutive integers starting with (n 1)! 2.]

Answers

It is proved that, for every positive integer n, there are n consecutive composite integers.

Given statement,

For every positive integer n, there are n consecutive composite integers.

Proof:

Assume that m is less than n and that both m and n are positive integers. When m is less than n,

n! = 1 ⋅ 2 ⋅ 3 ⋅ ⋅ ⋅ m ⋅ ⋅ ⋅ n,

which is to say that m is a factor of n!

So,

m + n! = m + ( 1 ⋅ 2 ⋅ 3 ⋅ ⋅ ⋅ m ⋅ ⋅ ⋅ n )

          = m ((1 ⋅ 2 ⋅ 3 ⋅ ⋅ ⋅ m ⋅ ⋅ ⋅ n) / m + 1)

Since m is a multiple of n!, n!/m is still an integer. Since the integer m is bounded between 1 and n, it follows that any number you choose up to n can divide m + n!, making it composite until the nth integer.

However, since n! contains the nth integer, the nth integer is also composite, meaning you can choose any integer between 1 and n inclusively and it will be composite.

(2x - 8)/(5x - 19) = (x + 2)/(3x + 6)

(2x - 8)/(5x - 19) = (x + 2)/3(x + 2)

(2x - 8)/(5x - 19) = 1/3

6x - 24 = 5x - 19

x = 5

Hence "The value of x for the given triangle by a similar triangle rule will be 5".

the attention span of a two-year-old is exponentially distributed with a mean of about 8 minutes. suppose we randomly survey 60 two-year-olds.

Answers

The mean has a value of 8 minutes and a standard deviation of 0.9736.

What is mean?

The sum of a set of numbers divided by the total number of numbers in the set is known as the arithmetic mean or arithmetic average in mathematics and statistics. The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including basic arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.

Here,

X= attention span of the 2 year old

μ=8

σ=8

m=1/8

X=exp(1/8)

mean=N(8,8/√60)

Mean is normally distributed with value about 8 minutes and difference being 0.9736.

Which is higher? Determine if I or II is higher or if they are equal. Explain your reasoning. For a regression line, the uncertainty associated with the slope estimate, b1, is higher when
I. there is a lot of scatter around the regression line or
II. there is very little scatter around the regression line

Answers

b1, is higher when: I. there is a lot of scatter around the regression line.

I is higher. The more scatter around the regression line, the higher the uncertainty associated with the slope estimate, b1. If there is a lot of scatter, the estimated slope is less reliable than if there is very little scatter.

The uncertainty associated with the slope estimate, b1, is higher when there is a lot of scatter around the regression line. This is because the estimate of the slope is based on the data points, and when there is a lot of scatter, the data points are more spread out and the estimate of the slope is less reliable.

The Importance of Scatter in Regression Analysis

In regression analysis, the scatter of data points around the regression line is important in determining the uncertainty of the slope estimate. When there is a lot of scatter, the data points are more spread out and the estimate of the slope is less reliable. This is because the estimate of the slope is based on the data points, and when there is more scatter, the data points are more spread out and the estimate of the slope is less reliable.
