Answer:
50%
Step-by-step explanation:
The interval between the first quartile,25-th percentile, (155) and the third quartile, 75-th percentile, (196) comprises 50% of the sample data.
The desired interval is from 155 to 195 pounds, which starts exactly at the first quartile and ends just one pound short of the third quartile. Since this sample has a large number of men and a range of 102 pounds, that one pound difference can be neglected. Therefore, the percent of men who gave a response that falls in the interval 155 to 195 pounds can be guessed to be roughly 50%.
Answer:
An equation has a equal sign, and it can be solved. A expression can only be simplified.
Step-by-step explanation:
Answer:
The factorised term is:
Step-by-step explanation:
We are asked to factor the algebraic expression given as:
Now we will take out the variable which is common among all the terms and write the remaining expression in parantheses.
As 
is common among all the terms hence we write this term out of the parantheses and the remaining term inside it as to obtain then simplified expression as:
Answer:
y=1/4x-2
Step-by-step explanation:
y=4x+8
INV
x=4y+8
(x-8)/4=y
y=1/4x-2
The answer would be:
8 and -1/8
1 and -1
And could be 0 and undefined, but I'm not 100% sure
