In statistical methods, the significance level is a value that is used as a criterion for rejecting a null hypothesis. It used by first looking at the differences between the experimental results and from there the null hypothesis would be determined. Then, we assume that the null hypothesis is true, the probability of the differences is computed by using statistical tools. If the computed probability is less than or equal to the value of the significance level, then you conclude that the null hypothesis should be rejected and that the results are statistically significant. Usually, a significance level of 1% or 5% is used.
Let's use x as the number of questions she answered correctly. If we make an equation of out the question, it would be 8.7x+13=108.7 To solve the equation subtract 13 from both sides. So it will leave you with 8.7x=108.7-13, which is 8.7x=95.7. Divide both sides by 8.7, which will give you x=11. She answered 11 questions correctly.
Answer:
B
Step-by-step explanation:
If 0.25 extra credit points are awarded for each additional correct extra cred question, q equals the number of extra cred questions answered correctly, and that will times with the 0.25 to give the overall extra credit score. To then arrive at the total current grade, Manson's average grade without extra cred must be added, therefore 87 must be his average grade.
Hello: <span>
<span> an equation is : y =ax+b ( a is a slope )
parallel to the line (q) : y=6/5x-1 a =6/5 ( same slope
)
the equation of (r) : is : y = 6/5x+b</span></span>
the line through point (5,5) :
5= (6/5)(5)+b ...b=-1
an equation of (r) : is : y = 6/5x-1
or : 6/5x-y = 1
Option two is the correct on
