Answer:
Question 7. -2 8. 3/2
Step-by-step explanation:
You can complete this by solving:
Which should give you .274418 or 27.44%
Y=2/3x -5/2
Slope is equal to the parallel line (2/3)
Find y intercept by setting y and x equal the given coordinates and solve.
X²+bx=c
x=[-b+√(b²+4c)]/2
2x(x+5)=4
2x²+10x=4
x²+5x=2
x=[-5+√(5²+4*4)]/2
if b=-1/2 and c=-9/2
x= {1/2+√[(1/2)²+4*(-9/2)]}/2
Answer:
31
Step-by-step explanation:
The range of a set of data is the difference between the highest and lowest values in the set.
First arrange all the figures in order from the smallest to the largest value
3,7,8,16,20,22,34
Therefore, finding range would be; 34-3 =31
Hope this helps!
