13.) since Death Valley is 282 below sea level, which will be represented by the integer 0, Death Valley can be represented by the integer, -282. Because Mount McKinley is 20,320 above sea level (represented by 0), it will be represented by the integer, 20,320. 

14.) No, there are no integers between 0 and 1 since integers are whole numbers without any decimals, and the only numbers between 0 and 1 are decimals.

A house was purchased in 2005 for $150,000. It is now valued at $135,000. What is the percent of change for the house?
Ann [662]
22,500+135,00= 157,000
15% is wrong, 15% equals 22,500

Next, 10% 15000

If you add 15000 to 135000 it will equal 150000 so 10% is correct.

valina [46]

Answer:

76,000,000

Step-by-step explanation:

Look at the 100,000 place and see whether to round up or down - 8 is larger than 5, therefore 75,000,000 gets rounded up to 76,000,000

Which of the following is used only in non-Euclidean geometry?
MatroZZZ [7]

Answer:c

Step-by-step explanation:none of these are good answers as they can all exist in flat Euclidean space. The best answer is c because a great circle exists in spherical (non-flat) geometry . However it’s not really correct to say you could never describe a great circle in Euclidean space and whoever wrote this question (not you, the original author of the question) deserves to bite their tongue on their dinner tonight

A standardized test was given to a set of high school juniors and the distribution of the data is bell shaped. The mean score is
stira [4]

Answer:

920 points.      

Step-by-step explanation:    

We have been given that the mean score for a standardized test is 800 and the standard deviation is 120. To qualify for a special summer camp for accelerated students, a student must score within the top 16% of all scores on the test.

First of all we will find probability of 0.16 using normal distribution table.

Using normal distribution our Z score will be 0.994458

Now we will use raw-score formula to find the score (x) that a student must make to qualify for summer camp.  

x=\text{Mean}+\text{ Standard deviation* Z score}

Upon substituting our given values in above formula we will get,

x=800+120\times 0.994458

x=800+119.33496

x=919.33496

Upon rounding to nearest whole number we will get,

x=920

Therefore, a student must make 920 points to qualify for summer camp.
