A part of the graph representing an electrical signal is shown. The voltage first rises steadily from an initial value (A) till

a maximum value (B) and then drops instantly till to the initial voltage (at C) and this repeats, such that || and and are vertical. If A = (1, 1) and B = (4, 3) respectively, then what is the equation of ? -3y – 2x = 5 3y – 2x = 5 3y – 2x = 5 3y + 2x = 5

True or False: A p is the probability that the results are not due to chance, the probability that the null hypothesis (H0) is f
professor190 [17]

Answer:

False

Step-by-step explanation:?

The hypothesis tests compare weather an event is meant to alter a population mean results, for example, a scientist experiment might have or not have a significant effect over the population results. The test aims to reject the null hypothesis, so what it really want to find out is if the alternative Hypothesis H1 is likely true. The null hypothesis is the probability that the results are not due to chance – if it’s rejected, then the results are due to chance.The level of significance , or so called p-value, is the probability that the null hypothesis (H0) happen , If p is very small then the null hypothesis is rejected - isn’t true- and the alternative Hypothesis is accepted. A higher P value implies a higher probability than results are not happening so that the H0 is accepted and H1 rejected. The null Hypothesis will normally will rejected when the level of significance are either lower than 0.05 or 0.01, the lower P value the higher the level of confidence that the results are due to chance.

Since the first part of the statement (A p is the probability that the results are not due to chance) is correct, and the second part is wrong (…the probability that the null hypothesis (H0) is false), the total statement is false. The correct statement would be as follows : A p is the probability that the results are not due to chance, the probability that the null hypothesis (H0) is true.

Answer:

\frac{x - 3}{x + 4}  \div  \frac{x ^{2} - 1 }{ x}   \\ = \frac{x - 3}{x + 4}  \times  \frac{x}{ {x}^{2}  - 1}  \\  =\frac{x(x - 3)}{(x + 4)( {x}^{2} - 1) }  \\=  \frac{x(x  - 3)}{(x + 4)(x  +  1)(x   -  1)}

Lee is thinking of two Numbers,the product is 18. the quotient is 2
defon
X, y - the numbers

The product is 18.
xy=18

The quotient is 2.
\frac{x}{y}=2 \ \ \ |\times y \\&#10;x=2y

Substitute 2y for x in the 1st equation:
2y \times y=18 \\&#10;2y^2=18 \ \ \ |\div 2 \\&#10;y^2=9 \\&#10;y=\pm \sqrt{9} \\&#10;y=3 \ \lor \ y=-3 \\ \\&#10;x=2y \\&#10;x=2 \times 3 \ \lor \ x=2 \times (-3) \\&#10;x=6 \ \lor \ x=-6 \\ \\&#10;(x,y)=(6,3) \hbox{ or } (x,y)=(-6,-3)

The numbers are 6 and 3 or -6 and -3.
