Answer:
The sample standard deviation is 15.3.
Step-by-step explanation:
Given data items,
84, 85, 83, 63, 61, 100, 98,
Number of data items, N = 7,
Let x represents the data item,
Mean of the data points,


Hence, sample standard deviation would be,






Answer:
I think C i'm not sure yet just let someone else answer and yea. But have a nice day as well.
Step-by-step explanation:
Answer:
4a.)
so the equation for this can be:
3/4 divided by 1/8
also, how many times can 1/8 go into 3/4
3/4=6/8
1/8 goes into 6/8 6 times, so 6 cupcakes out of the 8 cupcakes(or however many cupcakes there are - the problem doesn't specify that)
4b.)
3/4 ÷ 1/8
10.)
each square is 2 units wide(or long-whatever you wanna call it)
i don't really know how to explain this one, but i can just give you my answer (you can jut count up the squares along the outside of the polygon-the meaning of perimeter)
76 units
the bottom left one (i cant read the question number sorry)
1/10 of 237=
1/10*237=
237/10=
23.7
19.)
reflection pretty much means mirroring, so if you add the distance from E to the y axis and M to the y axis, you will get 10 (|-5|+|5|)
point m is in the 1st quadrant (sorry i don't really know how to explain this one either)
hope this helped!!
