Step-by-step explanation:
just look at the objects !
they are completely regular, and each arm can cover every other other arm.
so,
15A needs 1/3 of a full rotation.
15B needs 1/2 of a full rotation.
15C needs 1/4 of a full rotation.
15D needs (can you guess ?) ... 1/6 of a full rotation.
Answer:
x<-2 or x>6
written as x<-2;x>6
Step-by-step explanation:
Answer:
f= -15
Step-by-step explanation:
u just have to divide
-75/5= -15 so f equal -15
To find the IQR you first need to write it in numerical order
77, 81, 83, 84, 86, 86, 88, 92
IQR is just Q3 - Q1
Q1 is the middle of the first have, since it has an even set of 4 numbers in the first half you need to take the average of the two middle ones.. which is 82
Q3 done the same process would be 87.
87 - 82 = 5
IQR = 5
