Answer:
3
Step-by-step explanation:
17+x+12-0=32
29+x-0=32
29+x+32
x=32-29
x=3
Answer:
1,6 ,15,20,15,6,1
Step-by-step explanation:
The trick here is that the expansion are the
numbers in pascal triangle
1
1,1
1,2,1
1,3,3,1
1,4,6,41,
1,5 ,10, 10, 5, 1
1,6 ,15,20,15,6,1
In this case, since the standard deviation is known and
the sample size is less than 30, we will use the t-distribution. The formula
for calculating the confidence interval is:
Confidence Interval = X ± t * s / sqrt(n)
Where,
X = sample mean = $664.14
t = t score (taken from standard distribution tables)
s = standard deviation = $297.29
n = sample size = 14
At Degrees of Freedom = n – 1 = 13 and 98% Confidence
interval, z = 2.65
Substituting the values in the equation:
Confidence Interval = 664.14 ± 2.65 * 297.29 / sqrt(14)
Confidence Interval = 664.14 ± 210.55
Confidence Interval = 453.59 to 874.69

The compound interest is obtained as $91.81, rounded off to the nearest hundredth.
<h3>How is compound interest estimated annually?</h3>
In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest. The entire compound interest is then obtained by deducting the initial principal.
The equation that results will look like this:
Compound Interest =
Amount, rate of interest and time is given as $1500, 2% and 3 years respectively.
First, change r as a percent to r as a decimal.
r = R/100
r = 2/100
r = 0.02 rate per year,
Then solve the equation for compound interest.
So, the compound interest is obtained as $91.81, rounded off to the nearest hundredth.
