Answer:
y+3=4(x-5)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-3)=4(x-5)
y+3=4(x-5)
Answer:
Calculating 75% of a number is the same as calculating 25% less
Step-by-step explanation:

Answer:
Step-by-step explanation:
12 inches is in a foot
10 x 7= 70
2 x 7= 14
70+14=84
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
