Answer:
B
Step-by-step explanation:
The min and max numbers are 5.5 and 8.5. To find range, you subtract the bigger number by the smaller number. To find midrange, you find the median of the 2 min and max numbers.
8.5-5.5=3
5.5 6 6.5 7 7.5 8 8.5
1 2 3 4 5 6 7
So the range is 3 and the midrange is 7.

The numerator is the number of equal parts
Answer:
1,200
Step-by-step explanation:
Divide 800 by 40
Then take that answer which is 20 and multiply it by 60
Then you get 1,200
Answer: -2.8
Step-by-step explanation:
3t-(8/5) * 4-t < -7
(15t-8)/5 * 4-t < -7
((15t-8)(4-t))/5 < -7
(15t^2)-28t-32< -7
(15t^2)-28t-32-7< 0
(15t^2)-28t-39< 0
Using the quadratic/almighty formula
t= (-b +- ((b^2)-4ac)^(1/2)/2a)
a=15, b=-28, c=-39
t= (-(28) +- (((-28)^2)-4(15)(-39))^(1/2))/2(15))
t= -2.8 or t= 0.9
Since
t<0, then t= -2.8
