All you have to do is
1) order data from lest to greatest
2) find 2 middle number
3) add both numbers
4) put fraction and then put 2 under the bottom
(example)
27,33,38,41,42,52,60,64,68,72
^ ^ 42+52=94 divide by 2= 94/2
AVERAGE
Mean: 49.7 Median:47
Answer:
9
Step-by-step explanation:
To calculate c from the first right angle triangle,
C2 = 36 + 16
C = sqrt(52)
To calculate a from the bigger right angle triangle,
B2 + 52 = (a + 4)2
B2 - a2 = -36 + 8a
A2 + 36 = B2
Solving both by elimination,
A = 72/8
=9
Plug the 3 in for x because x=3 so it’ll be 6(3)+7 and that equals 25
B < 11 = the board is shorter than 11 cm.
B > 11 = the box contains more then 11 books.
B < 12 = there are fewer than 12 beetles in a jar
B > 12 = the building is taller than 12 ft.
I hope this helped :)
