Answer: 3
Step-by-step explanation:
Median is the middle number if it is an odd number or if it is even you add the two middle numbers and divide by 2
-2 [9-(x+7)]=-2 [9-x-7]=-18+2x+14=2×=-14+18
2x=4
x=4/2x
x=2
Answer:
False
Step-by-step explanation:
Midrange is the average of the difference between the maximum and minimum
√(t + 3) = 14 ← -2 both sides
t + 3 = 196 ← square both sides
t = 193 ← subtract 3 from both sides
5x² + 8x + 3 = 0 ← put in standard form
(5x + 3)(x + 1) = 0 ← factor
5x + 3 = 0 or x + 1 = 0 ←Zero product property
x =
or x = -1
The original price is $130
you should find out 19.5 is 15% of what number ( if he saved $19.5
so the 15% off sale was $19.5 less than the original price.) the answer will be :
19.5*100 /15 = 1950 /15= 130
good luck
