Actually Welcome to the Concept of the areas,

Area of a rectangle = length * width.

hence, l = 11 and w = 4

hence, 4*11 = 44 square units.

Area = 44 sq. units

What is class boundaries's answer?

Snowcat [4.5K]

Answer:

class boundaries are the end points of an open interval which contains the class interval such that the lower class boundary (LCB) is the LCL minus one-half the tolerance and the upper class boundary (UCB) is the UCL plus one -half the tolerance.

The harmonic mean of two real numbers x and y equals 2xy/(x + y). By computing the harmonic and geometric means of different pai

olasank [31]

Answer:

Conjecture : 2xy / ( x + y ) ≤ √xy

Step-by-step explanation:

Harmonic mean of x and y = 2xy/( x + y )

<u>Formulate a conjecture about their relative sizes </u>

we will achieve this by computing harmonic and geometric means

Geometric mean = √xy

harmonic mean = 2xy/( x + y )

Conjecture : 2xy / ( x + y ) ≤ √xy

attached below is the proof

find the margin of error to use for this sample mean sushi based on a sample of 35 people he average out of pieces of sushi a pe

NNADVOKAT [17]

Answer:

{13.7756,18.2244}

Step-by-step explanation:

Given the sample size, the margin of error can be calculated with the formula $M=Z*\frac{\sigma}{\sqrt{n}}$ where Z is the critical value for the desired confidence level, σ is the population standard deviation, and n is the sample size. Therefore, our margin of error for a 90% confidence level is:

$M=Z*\frac{\sigma}{\sqrt{n}}=1.645*(\frac{8}{\sqrt{35}})=2.2244$

The formula for a confidence interval is $CI=\bar{x}+M$ where x-bar is the sample mean. Therefore, the 90% confidence interval for the mean amount of sushi pieces a person can eat is:

$CI=\bar{x}\pm[M]=16\pm2.2244={13.7756,18.2244}$

Therefore, we are 90% confident that the true mean amount of sushi pieces a person can eat is contained within the interval {13.7756,18.2244}

What is the difference between no solution and no real solution? When do you get multiple solutions? This is for solving absolut

shepuryov [24]

No solution means u can graph the two equations and it would form parallel lines and would never intersect while, no real solution when graph the two equations would form the same line. When dealing with absolute value equation an equation with a degree larger than one,theres a chance it can be multiple solutions
