Chi-Square Test Chi-square is a statistical test commonly used to compare observed data with data we would expect to obtain according to a specific hypothesis. For example‚ if‚ according to Mendel’s laws‚ you expected 10 of 20 offspring from a cross to be male and the actual observed number was 8 males‚ then you might want to know about the "goodness to fit" between the observed and expected. Were the deviations (differences between observed and expected) the result of chance‚ or were they due to

1.) What does the pilot want? To save the girl. 2.) Is the pilot likely to succeed? Most likely not because by doing so he would kill others. 3.)What does the sister want? She wants to live. 4.) Is the sister likely to succeed? I doubt it cause of there being a law and there seems theers no other way then her diying. 5.) What does the government want? For the girl to be thrown off the ship. 6.) Is the government likely to succeed? I belive so. 7.) What should happen? The girl should be saved

The Vector equation of a plane To find the vector equation of a plane a point on the plane and two different direction vectors are required. The equation is defined as: where a is the point on the plane and b and c are the vectors. This equation can then be written as: The Cartesian equation of a plane The cartesian equation of the plane is easier to use. The equation is defined as: One of the advantages to writing the equation in cartesian form is that we can easily find the normal

Accounting Equation Paper Student Course Date Instructor Accounting Equation Paper The accounting equation which we know as Assets equals to Liabilities plus Equity for a sole proprietorship and for a corporation we know it as Assets equals to liabilities plus stockholders & equity. Assets are company owned‚ liabilities are what company owes and the difference between the both of them is the owner’s equity‚ these three things are what the companies

Completing an RTI Model MTE 562 December 7‚ 2014 Francine Young Completing an RTI Model Fourth grade student Jasmine Keller was informally assessed in 2009 and found to be reading at a level between first and second grade. Her vocabulary is stronger and at grade level with 85% accuracy. Evidence also from 2009 indicates Jasmine is able to produce ideas and sequence meaningful supporting details. Additionally‚ her math computation is weak and a pre-assessment found her scoring 32 facts

The goal for this experiment is to determine which out of the four balanced chemical equations best represent the thermal decomposition of sodium bicarbonate. The guiding question will be answered with the outcome of the sodium bicarbonates thermal decomposition and it being plugged in into the four balanced chemical equations. John Dalton atomic theory explains two fundamental laws of chemistry which are the law of conservation of mass and the law of definite proportions. The atomic theory states

Lines: Equation of a straight line is y = mx + c‚ where m = gradient‚ c = y-intercept. The equation of a line‚ if we know one point and the gradient is found using: (y - y1) = m(x - x1) (If given two points‚ find the gradient first‚ and then use the formula.) Two lines meet at the solution to their simultaneous equations. Note: When a line meets a curve there will be 0‚ 1‚ or two solutions. 1. Use substitution to solve the simultaneous equations 2. Rearrange them to form a quadratic equation

Continuity Equations Continuity equation is a equation that explain the transport of a conserved quantity. Since‚ mass‚ energy‚ momentum are conserved under respective condition‚ a variety of physical phenomena may be describe using continuity equations. By using first law of thermodynamics‚ energy cannot be created or destroyed. It can only transfer by continuous flow. Total continuity equation (TCE)‚ component continuity equation(CCE) and energy equation(EE) is applied to do mathematical model

Scranton Engineers Club. This formula is given as Where σp is pillar strength‚ σ1 is uniaxial compressive strength of a cubical specimen (w/h = 1)‚ and w and h are pillar dimensions. According to Obert and Duvall‚ this equation is valid for w/h ratios of 0.25 to 4.0‚ assuming gravity-loading conditions. Through back calculations from mining case histories and utilization of laboratory rock properties‚ safety factors of 2 to 4 were derived for short- and long-term pillar
