Determine the final amount after 20 years with a 5% annual interest rate if:you invest $10 000 in an account that earns compound

alekssr [168]

Answer:

$27,014.85

Step-by-step explanation:

We're gonna use the compound interest formula: P = A(1 + r/n)^nt

P = final amount

A = starting amount (10,000)

r = rate (0.05)

n = times applied (4 since it's quarterly)

t = years (20)

P = 10,000(1 + 0.05/4)^4*20

P = 10,000(1.0125)^80

P = 27,014.84940753337

Round it to just 27,014.85

Assume that all conditions are met. The mean of the differences was 1. 33 and the standard deviation of those differences was 2.

Maurinko [17]

The test statistic for this procedure is using two sample T-test is 0.458.

Definition of Two Sample T-test

A variation of the Student's t-test used to determine if two sample means are substantially different is known as the two sample T-test (also known as Welch's t-test, Welch's adjusted T, or unequal variances t-test). The test's degrees of freedom have been changed, which generally boosts the test's power for samples with unequal variance.

T-Test Statistic for The Procedure

It is given that mean of the differences = 1.33

And, the standard deviation of the differences, standard error = 2.90

The test static formula is given as,

t = (estimate - hypothized value) / standard error

Here, t is the t- test statistic, and estimate is the mean of the differences.

Since it is given that all conditions are met, the hypothized value can be taken as 0

Substituting substituting estimate = 1.33 and standard error = 2.90 in the t-test statistic formula, we get,

t = (1.33-0)/2.90

or t = 0.458

At Westside Middle School, 10 percent, or 140 students, participate in soccer. How many students are in the school? Check all th

Aleonysh [2.5K]

Answer: There are 1,400 students in the school. Checked options are bolded.

Step-by-step explanation:

How many students in the school?

$\frac{1}{10} = \frac{140}{x}$ (10% of the school population is equal to 140 over unknown)

$x = 1,400$ (unknown equals 1,400)

Check all that apply:

The total number of students is greater than 140.
The total number of students is less than 140.
(10)(14) = 140, so 100(14) = 1,400 students.
140 + 10 = 150, so 150 + 140 = 290 students.
There are 140 + 10 = 150 students at Westside Middle School.
The percent as a part to whole ratio is StartFraction 140 Over 100 EndFraction
The percent as a part to whole ratio is StartFraction 10 Over 100 EndFraction
