Answer:
The answer to your question is the letter D. 30 pounds
Step-by-step explanation:
Data
increase = 50%
final weighed = 45 pounds
Process
1.- Use proportions to solve this problem. 45 pounds will be 150% (the initial 100% plus an increase of 50%).
45 pounds ------------------ 150%
x pounds ----------------- 100%
x = (100 x 45)/150
x = 4500/150
Result
x = 30 pounds
Answer:
$30
Step-by-step explanation:
If 2kg costs $15, then 4kg will cost double that because you are doubling 2kg
PLEASE MARK ME AS BRAINLIEST
30/40 say no, so x/1000 would say no. 1000/40=25, 25*30=750. So, about 750 would dislike it.

Answer:
4
Step-by-step explanation:
Class width is said to be the difference between the upper class limit and the lower class limit consecutive classes of a grouped data. To calculate class width, this formula can be used:
CW = UCL - LCL
Where,
CW= Class width
UCL= Upper class limit
LCL= Lower class limit
From the table above:
For class 1, CW = 64 - 60 = 4
For class 2, CW = 69 - 65 = 4
For class 3, CW = 74 - 70 = 4
For class 4, CW = 79 - 75 = 4
For class 5, CW = 84 - 80 = 4
Therefore, the class width of the grouped data = 4
