Answer:
f $270= the remaining 24% then you want to do 270/24=11.25 Then you want to multiply that by 76 and you will get $855
So $270+$855=24%+76% So his monthly salary was $1,125
If you are still confused do it in reverse! 1,125/100=11.25
11.25•24=270 & 11.25•76=855
270+855=1,125

Answer:
The sample size needed is 2401.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error of the interval is:
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
Estimate the sample size needed if no estimate of p is available so that the confidence interval will have a margin of error of 0.02.
We have to find n, for which M = 0.02.
There is no estimate of p available, so we use 
The sample size needed is 2401.
Answer:
I don't understand what you are trying to ask? Sorry
you have the ratio of natural:synthetic so;
3:4
3+4=7
357/7=51
3*51:4°51
153:204
therefore, it'd be 204 litres of synthetic oil!!
i hope this helps you!!
