Answer:
A parrallelogram
Step-by-step explanation:
It would be a rhombus because when the 2 diagnols bisect eachother, angle b =91, so that means b would be half of that and all angles in rhombus are equal i tink. I am in 7th grade so idk but that is what i think.
6) answer is B , random sampling produces a representative sample
7) 0.1 = 10% so the answer is A, he saves 10% of his income
To add fractions you want to make sure that the bottom numbers are the same so we have to make them the same, but we have to make sure that the fractions are unchanged so we get the correct answer
so if we find out what number that 9,7, and 5 can all multiply into. we find that 9 times 7 times 5 or 315 is the number that will work
so to get them to all be over 315, we must multiply each fraction by a form of 1/1 or x/x or (number)/(same numbe as on top)
so 7/9 times (35/35)=245/315
1/7 times (45/45)=45/315
3/5 times (56/56)=168/315
we add them togther
245/315+45/315+168/315=(245+45+168)/315=458/315
this simplifies to 1 and 143/315
Answer:
And replacing the data into the average rate formula we got:
And then the best answer for this case would be:
C. 27.5
Step-by-step explanation:
For this cae we know that the average rate of change of a function is given by this general expresion:
For this special case from the info of the table we have:
And replacing the data into the average rate formula we got:
And then the best answer for this case would be:
C. 27.5
