It takes 3/9 to make 1/3.
You multiply the 1 (in 1/3) by 3, and you multiply the 3 (in 1/3) by 3. You get 3/9. You needed to multiply by 3 to make 1/3 have a common denominator is 9.
Answer:
42
Step-by-step explanation:
84 divide 2
answer 42
answer =42
Answer:
Step-by-step explanation:
1) So -8+2v<2, 2v<10, v<5. That means that at "5" on the axis, you'll draw a circle that's <em>not</em> filled in (because it's <5, not 
5) and then draw a box-y thing to the left. Sorry, can't really describe it, but if you look at the picture attached, you'll understand
2) -12m-8-5m-7m, so -12m-8-12m, -80. This one doesn't have a variable... so you can't really graph it?
I am guessing there is half of each type of book, so there are 50/100 or 1/2 that are fiction
hope this helped
Full Question
As a secondary mathematics teacher, Hernandez conducted a study that explored whether giving children recess prior to testing helped their test performance. For one of the semesters, he sends half of his classes out for 10 minutes of recess prior to testing for the other half, he provides 10 minutes of free time after the test. Which of the following best represents the design of Hernandez's study?
a. One-shot case study
b. Post-test only control group
c. Solomon four group
d. Static-group comparison
Answer:
Static-Group Comparison
Explanation:
A Static-Group Comparison describes a study that involves two non-randomly selected groups, where one groups receive the treatment, and the other does not before the test. Afterwards, a post-test examination of the score is then carried out to examine the different in performance between both groups.
