Answer:
3/41; 1/6 40/97
Step-by-step explanation:
Use ratio and proportion
80/120=x/100
cross multiply
x= 66 2/3 percent
Answer:
10 hours
Step-by-step explanation:
Because if u divide the speed t= 4320miles/432mph=10h
Answer:
Hence the best estimate is population with correct option is 74% and
the value for x=148
Step-by-step explanation:
Given:
A sample of 200
Of which 148 prefer brand new coffee
To Find:
Which statement is true?
Solution:
n=200
x=148
remaining 52 prefer old ones .
So estimate population proportion,
p=x/n
p=148/200
p=0.74
p=74 %
Now, when x=52
p=x/n,
p=52/200
p=0.26
p=26%
There is no option for 52 and 24 %
Hence x=148 and p=74%.
