Answer:

The total amount due after five years is $57,000.

Step-by-step explanation:

Recall that simple interest is given by the formula:

\displaystyle A=P(1+rt)

Where <em>A</em> is the final amount, <em>P</em> is the principal amount, <em>r</em> is the rate, and <em>t</em> is the time (in years).

Since we are investing a principal amount of $38,000 at a rate of 10.0% for five years, <em>P</em> = 38000, <em>r</em> = 0.1, and <em>t</em> = 5. Substitute:

\displaystyle A=38000(1+(0.1)(5))

Evaluate. Hence:

\displaystyle A=\$ 57,000

The total amount due after five years is $57,000.

It is generally believed that the mean value of the district's total SAT score distribution is equal to 1200 (the null hypothesi
g100num [7]

Answer:

The corresponding p-value, is p = 1

Step-by-step explanation:

The maximum score SAT score, n =  1,600

The mean of the district's total SAT score distribution = 1,200

The claim of one of the districts principal, is the that mean of the district's total SAT score distribution ≠ 1,200

Using proportions, we have;

p = 1,200/1,600 = 0.75

q = 1 - p = 0.25

The margin of error, E = Z√(p·q/n)

∴ E = 5% = Z×√((0.75 × 0.25)/1,600)

z = 0.05/(√((0.75 × 0.25)/1,600)) ≈ 4.61880

Therefore, the corresponding p-value, p = 1

Anjali was keeping track of how far she walked. She walked 1 1/10 miles on Monday, 4 4/5 miles on Wednesday, and 2 1/4 on Friday
Bumek [7]

Answer:

8.15 miles

Step-by-step explanation:

Monday: 1 1/10 miles = 1.1

Multiply by 10 to get to 100

Wednesday: 4 4/5 miles = 4.8

Multiply by 20 to get to 100

Friday: 2 1/4 miles = 2.25

Multiply by 25 to get to 100

1.1 + 4.8 + 2.25 = 8.15 miles

Outliers can cause the _________ to be misleading when summarizing a data set.
gladu [14]

Hello!

An outlier can cause the mean to be misleading. If you have an outlier when finding the median or IQR, it will not throw off the data by much. But adding a very large or small number to the mean, and dividing it by an extra number, it will throw the number off by a large amount.

I hope this helps!
