Answer:
B. Set the alpha level at 0.05.
Step-by-step explanation:
Hypothesis testing is a procedure whereby a researcher determines if the null hypothesis is rejected or accepted, depending on the significant level or the alpha level. When a type I error is made, the null hypothesis is rejected even though it is correct. To solve this problem, the significant or alpha level is set to 5% or 0.05.
First:
Subtract 5 on each side of the equals sign to cancel it out. You should get 13x=144.
Next:
Divide 13 from each side of the equals sign to get x by itself.
Answer:
X=11.0769230769. You may need to round it up to 11.08 or 11.1 depending on how your teacher normally has you answer
Answer:
4/5
Step-by-step explanation:
y = mx + b
4/5 = m = slope
Answer:
Since, the sides are proportional. Therefore, the two triangles are similar.
Step-by-step explanation:
Since:
and
also,
i.e., The sides are proportional.
Therefore, the two triangles are similar.
A distinct real solution is a solution to an equation that occurs once, and differs in value from other solutions. For example, in the equation above there are two distinct real solutions: x = − 13 2 and x = 13 2 . Since they are different, real numbers, the equation has two distinct real solutions.
The value of the discriminant determines how many solutions the quadratic will have. Equation 1: the discriminant was zero, there was only 1 solution. Equation 2: the discriminant was a negative number, there was no solution. Equation 3: the discriminant was a positive number, there were two solutions.
