What is the percent of change from 45 to 56 round to the nearest percent

Answers

Step-by-step explanation:

This problem is not about percent or relative change, but about absolute change. Its solution is very simple:

Absolute change, or

change = new value - old value

= 56 - 45 = 11 (increase)

A test to detect an infection gives a positive result 98% of the time if a person is infected, and it is 97% accurate for people who are not infected. What percentage of results will be false negatives?a) 1%

b) 2%

c) 3%

d) 5%

Answers

The answer is c.) 2%. Since the question is talking about false negatives, meaning the chance that the results are false, then we take a look at the 98% which represents the chance of giving an accurate result for the people who are not infected meaning for those who are positive. Thus, the answer is 2% because this is the remaining percentage if 100-98%.

What is the degree of the polynomial 3xy^2z−2z^5+2/3y^2z^4 ?

Answers

Answer:

6 is the answer

Answer:

Step-by-step explanation:

The table below shows the velocity y, in miles per minute, of a toy car at different times x, in minutes:Time (x)
(minutes) 10 20 30 40
Velocity (y)
(miles) 0.2 0.8 0.1 0.4

Part B: What is the value of the slope of the graph of velocity versus time between 10 minutes and 20 minutes, and what does the slope represent? (3 points)

Answers

The value of the slope of the graph of the velocity versus time between 10 minutes and 20 minutes would be .06. I got to this answer by getting the changes in the rise (y) over run (x) of the table:

slope = y2- y1 / x2-x1
= .8-.2 / 20-10 mi / min
= .6 / 10 min
= .06

Then for the follow up question, the slope represents the distance traveled of the toy car (in miles).
