We have been given that a colleague has been tutoring six students in 11th grade to prepare for the ACT. Student scores were as follows: 20, 18, 16, 15, 23, 20. We are asked to find the mean of the ACT scores.
We will use mean formula to solve our given problem.




Upon rounding to nearest whole number, we will get:

Therefore, the mean of the ACT scores is 19 and option 'c' is the correct choice.
That questions has to do with equivalent fractions, express a fraction in eights.
six and three quarters
= 6 3/4
<span>= 6 + 3/4
</span>= 24/4 + 3/4
= 27/4
and to convert that fraction to eights, just multiply numerator and denominator by 2:
= (27*2)/(4*2)
= 54/8
there are 54 eights in six and three quarters
Answer:
C a dilation will always produce similar figures
Step-by-step explanation:
If the scale factor is >1 then the figure will get larger
< 1 the figure gets smaller
=1 it is congruent
We can rotate the figure but that is not by dilation. dilation does not change the orientation, unless the scale factor is negative( which is a reflection)
