Answer:
Given h(x) = -x + 2, find h(4).
Step-by-step explanation:
T=i/pr
t=252÷(1,200×0.07)
t=3 years
I think you'd answer it like this;
£105 / 3 = 35.
So now we know 35 is the number that was multiplied.
You add the ratios, 2+3+4, which is 9.
35 x 9 = £315.
Millie gets 70
Josh gets 105
and that leaves 140 for Liberty.
The total amount of money before it was divided is : £315.
Answer:
The confidence interval has an lower limit of 
and an upper limit of 
, in which 
is the sample proportion and 
is the size of the sample.
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 z-score that has a p-value of 
.
90% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The confidence interval has an lower limit of and an upper limit of , in which is the sample proportion and is the size of the sample.
