A university wants to investigate how much its students spend on textbooks each semester. Since all
students must purchase their materials through the campus bookstore, a random sample of 15 student
accounts is selected, and the averagą dollar amount spent on textbooks is calculated.
Which of these circumstances would make it inappropriate to use this sample to calculate a 95%
confidence interval for the mean amount spent on books by students at this university?
The standard deviation of the textbook costs is below $30.
The standard deviation of the textbook costs is larger than $100.
A stem-and-leaf plot of the textbook costs shows a roughly symmetric distribution
A histogram of the textbook costs is calculated and shows a slight skew to the right.
A boxplot of the textbook costs shows two students whose amounts would qualify as outliers,

11. If you randomly selected 500 U.S. homes, about
how many would be heated with fuel oil?

Answers

Answer:

50

Step-by-step explanation:

Given

Total number of US houses = 500

If 10% were affected by fuel oil

Total number affected by fuel oil = 10% of 500

Total number affected by fuel oil = 0.1 * 500

Total number affected by fuel oil = 50

Hence 50 houses were affected by fuel oil

Answer:

Step-by-step explanation:

"Triples in size" means the growth factor is 3, so we expect to see that as the base of the exponent. That growth factor applies to a period of 6 minutes, or 1/10 hours. The number of 6-minute intervals in t hours is 10t, so we expect to see that as the exponent. The appropriate model could be written ...

Answer:

90

Step-by-step explanation:

Remeber there are 180 degress in a right triangle.

Answer:

y = 90°

Step-by-step explanation:

Y is 90 degrees. The base of the triangle seems to be bisected by a perpendicular bisector. The resulting angles are 90 degrees on both sides. And seeing as 90 is y, x is 20.

To be more precise. We know this is an isosceles triangle, due to the fact that the angle right of 110 must be 70 degrees (they are supplementary angles.) The entire triangle must add up to 180 by the triangle angles sum theorem, and two 70 degree angles add up to 140, meaning the last angle is 40 degrees. That final angle is bisected, meaning each part is 40/2, that's 20.

A badminton tournament begins with 512 teams. If a team loses once, it is eliminated from competition. After the first round, 256 teams remain. After the 4th round, how many teams remain? How many rounds will be required to determine the champion?

Answers

Answer:

This is GP with the first term of 512 and common ratio of 1/2

The formula for nth term is:

aₙ = 512*(1/2)ⁿ

The number of teams after the 4th round:

a₄ = 512*(1/2)⁴ = 32 teams

Number of rounds to determine the champion:

1 = 512*(1/2)ⁿ2⁰ = 2⁹*2⁻ⁿ0 = 9 - n n = 9 rounds
