f(x)=0
Domain are the set of x values
f(x)=0 , we find all the x values where y =0
At x intercepts y is always 0
so we find all the x intercepts.
x intercepts are the points where the graph crosses x axis
In the graph we can see that the graph crosses x axis at
-2.5 , -0.75 and 1
-2.5 , -0.75 and 1 are the domain where f(x)=0
Find current interest:
=$2543.32 * 17.4%
=2543.32 * 0.174
=442.537
Add the interest to the current balance:
=2543.32 + 442.537
=2985.857
Add new transaction:
=2985.857 + 320
=3305.857 rounded to 3305.86
The answer is C) $3305.86

Answer:
The 98% confidence interval of the proportion = (0.312, 0.374)
Step-by-step explanation:
(Give answers accurate to 3 decimal places.)
The formula for Confidence Interval of Proportion is given as:
p ± z × √p(1 - p)/n
Where p = Proportion = x/n
x = 440
n = 1282
p = 440/1282 = 0.34321372854
Approximately = 0.343
z = z-score of 98 % confidence interval
= 2.326
Confidence Interval =
= 0.343 ± 2.326 × √0.343(1 - 0.343)/1282
= 0.343 ± 2.326 × √0.225351/1282
= 0.343 ± 2.326 × √0.00017578081
= 0.343 ± 2.326 × 0.01325823555
= 0.343 ± 0.03083865589
0.343 - 0.03083865589
= 0.31216134411
Approximately = 0.312
0.343 + 0.03083865589
= 0.37383865589
Approximately to = 0.374
Therefore, the 98% confidence interval of the proportion = (0.312, 0.374)
Answer:
the rate of inflation is 2%.
Step-by-step explanation:
given:
Nominal interest rate =3%
Real interest rate=1%
To Find:
Rate of inflation=?
Solution:
Nominal interest rate:
Nominal interest rate refers to the interest rate before taking inflation into account.
Inflation rate:
The inflation rate is the percent increase or decrease in prices during a specified period. It's usually over a month or a year.
Real interest rate:
A real interest rate is an interest rate that has been adjusted to remove the effects of inflation to reflect the real cost of funds to the borrower and the real yield to the lender or to an investor.
Real interest rate ≈ nominal interest rate − inflation rate.
This can be re written as
inflation rate= Real interest rate - nominal interest rate
Substituting the values,
inflation interest = 1+3
inflation interest=4%
i hope this helpsss<3
:)
if u didnt undersstand make sure to tell me so i can try to say it again
