Answer:
<em>The percent error of the cyclist's estimate is 5.63%</em>
Step-by-step explanation:
<u>Percentages</u>
The cyclist estimates he will bike 80 miles this week, but he really bikes 75.5 miles.
The error of his estimate in miles can be calculated as the difference between his estimate and the real outcome:
Error = 80 miles - 75.5 miles = 4.5 miles
To calculate the error as a percent, we divide that quantity by the original estimate and multiply by 100%:
Error% = 4.5 / 80 * 100 = 5.625%
Rounding to the nearest hundredth:
The percent error of the cyclist's estimate is 5.63%
Answer:
(x²-2x)/(2x+6)
Step-by-step explanation:
When you are asked to divide two fractions just do keep-change-flip. Keep the first fraction, change the ÷ to x and flip the second fraction upside down. So the problem becomes ((x-2)/(x+3)) times (x/2). Then just multiply numerators and multiply denominators.
Answer:
-4 is the correct answer to this problem
Answer:
The answer is in the image! The interval notation is [-5,4)
Step-by-step explanation:
Notice that on the linee graph it shows a open circle on 4 and a closed dot on -5... This is because the number can be greater than -5 or equal to(this is represented by the brackets) and on 4 it can only be less than 4 and not equal to it (Represented by parenthesis)...
To solve for the inequality you must solve for x. The easiest way to do this is to multiply each component in the middlee by 3, the add two on both sides, then divide by 9 on both sides. This gives you the simplest inequality at -5<= x <4!
Hope this helps! If you cant open the image let me know!
Answer:
A
E
Step-by-step explanation:
sqrt25 is 5 and since sqrt29 is bigger than sqrt 25 the inequality is true
sqrt4 is 2 and since sqrt 3 is less than 4 the inequality is false
sqrt49 is 7 and since sqrt50 is bigger than 49 it is false
sqrt64 is 8 and since 61 is smaller than 64 it is false
sqrt 36 is 6 and since sqrt 31 is smaller the equation is true
