Answer:
The 65th percentile is 37
Step-by-step explanation:
The 65th percentile is the number that splits the data in two groups. The amount of data that is less to the 65th percentile corresponds to the 65% of the data. Since we have 20 value, we calculate the 65% of 20, which is 13. By organazing the data from least to greatest, we count the values in the data set until we reach the 13th value, which in this case is 37.

Answer:
140
Step-by-step explanation:
When working HCF and LCM problems, I like to think in terms of this little diagram:
(a [ b ) c]
It shows me one of the numbers is ab, the other is bc, the HCF is b and the LCM is abc. "a" and "c" must be relatively prime for "b" to be the HCF.
__
Here, we're given ...
b = 20
ab = 320
abc = 2240
Then ...
c = abc/(ab) = 2240/320 = 7
x = bc = 20(7) . . . . . . equivalently, x = (abc·b)/(ab) = (2240·20)/320
x = 140
Answer:
I believe it is C... since the largest angle is always across from the longest side, where as the smallest angle is across from the shortest side.

Recall that two shapes are congruent if they have the same shape and size. When two shapes have the same shape but different sizes, we call the shapes similar. You can also think of similar objects or shapes as scaled versions of each other.
