Answer:
8,55
Step-by-step explanation:
use trigonometric functions
Hello! Here is your answer!
Mean: the mean is the number's all added up and then divided by the number of number's in the equation,
Example:
24 58 93 44 56 Now first we add 24 = 58 = 82 82 + 93 = 257 257 + 44 =
301 301 + 56 = 357 Now we divide our number by the amount of number's
listed "24 58 93 44 56" 357 ÷ 5 = 71.4! And that is the mean,
Mode: Now the mode is the most used number we need to find that to get our answer,
Example: 28 34 58 28 34 53 24 28 Now as you can see there is two 34's one 58 one 53 one 24 and three 28's so the mode is 28!,
Median: The median is the middle number if there is none it would be the half of the two middle number's,
Example: 0 10 20 30 40 50 60 70 80 90 100 The median is 50 to get it simply divide 100 by 2 so the median is once again 50,
Further example: To get the median when there is no middle number 20 35 45 60 80 you would simply get the number between 35 and 45 so the median would be 40,
Range: To find the range you must subtract the highest number by the lowest number
Example: 41 56 58 55 23 63 now we find the highest and lowest number 23 and 63 so we subtract 63 by 23 63 - 23 = 40 so the range is 40. Hope this helps you! :)
Answer:
Step-by-step explanation:
The average rate of change is the slope. However, since this is not a linear function but an exponential one, we cannot determine the slope of the function, only the slope of the secant line that connects the x-values of 4 and 8. In order to do that we need to find the corresponding y-coordinate that goes with each of those x-values and plug them into the slope function. What we will get is a very loose interpretation of the rate of change of population, but that's all we have short of using calculus. It would be a closer estimation if we looked at x values of 4 and 5, or eve 4 ad 4.5. But that's not what we're being asked. So let's get to it.
Sub first 4 in for x and then 8, to get each y value:
to get that P(4) = 2742.16
to get that P(8) = 2937.29
The coordinates for these are (4, 2742.16) and (8, 2937.29)
Plug into the slope formula:
which gives you, in decimal form rounded to the nearest hundredth,
48.78 million.
The interpretation of this value in our situation is that between 1954 and 1958 the population increased 48.78 million people per year.
When distributing the negative three into the parentheses, that canceled out the -5 and made it a positive 15
Answer:
Step-by-step explanation:
Let x represent the larger number.
Let y represent the smaller number.
The sum of two numbers is thirty seven. This means that the smaller number would be 37 - x
The translation into a variable expression for the the difference between nine more than twice the larger number and the sum of the smaller number and three would be
2x + 9 - (37 - x + 3)
Opening the parenthesis and putting the constants together, it becomes
2x + 9 - 37 + x - 3
2x + x + 9 - 37 - 3
3x - 31
