A.)ii. and iii. B.)ii. C.)i. D.)i. and iv.

Mathematics

Vlad [161]3 years ago

The answer is B) ii

The notation "p --> q" means "if p, then q". For example

p = it rains
q = the grass gets wet

So instead of writing out "if it rains, then the grass gets wet" we can write "p --> q" or "if p, then q". The former notation is preferred in a math class like this. 

So when is the overall statement p --> q false? Well only if p is true leads to q being false. Why is that? It's because p must lead to q being true. The statement strongly implies this. If it rained and the grass didn't get wet, then the original "if...then" statement would be a lie, which is how I think of a logical false statement. 

If it didn't rain (p = false), then the original "if...then" statement is irrelevant. It only applies if p were true. If p is false, then the conditional statement is known to be vacuously true. So this why cases iii and iv are true.

STatiana [176]

Answer:

  • The general equation of the circle is
  • ( {x - a})^{2}  +  ({y - b})^{2}  =  {r}^{2}  \\ therefore \:  we \: \: have \:  \\ ( {x - 2})^{2}  + (y - ( - 5)) {}^{2}  =  ({16})^{2}  \\  ({x - 2})^{2}  + ( {y + 5})^{2}  = 256

A line of best fit predicts that when x equals 28, y will equal 27.255, but y actually equals 26. What is the residual in this c
zlopas [31]

Answer:

C) -1.255

Step-by-step explanation:

We are tasked to solve for the residual value given that when x equals 29, y will be equals to 27.255. But, when it is tested, y actual value is 26. The formula in solving residual is shown below:

Residual value = Observed value - predicted value

Residual value =  26 - 27.255

Residual values = -1.255

The answer is -1.255 for residual value.
