The expression:
3 (x - 2)
indicates that the number 3 before the parenthesis is multiplying the expression inside the parenthesis.
Then in order to do such we use what is called the distributive property which tells us to "distrubute" suche multiplication among the two term that are in the parenthesis:
3 x - 3 * 2
3 x - 6
Which is the first option in your answer list.
the answer for this question is 25,672
Answer:
Step-by-step explanation:
a) it is true that the bigger the sample size, the more accurate the reported average of the sample. An increased sample size gives a smaller standard deviation. This improves accuracy.
b) It is false. A type 1 error occurs when a true null hypothesis is rejected
c) It is true. The null hypothesis is considered true until the alternative hypothesis which is contrary is favoured by sufficient evidence.
First subtract 30 from both sides so it is equal to 0
the quadratic formula is -b plus or minus sqrt of (b^2 - 4ac) all over 2a so
-10 plus or minus sqrt (100-25) all over 2
this is equivalent to
