Answer:
60 degrees
Step-by-step explanation:
Angles in a triangle add up to 180
79 add 41 is 120
180 minus 120 is 60
Answer:
Step-by-step explanation:
To find the population variance, we first need the mean:
so the mean is 7.2. To find the population variance (which is almost exactly the same as the sample variance except for a small difference in the denominators of the formula) we have to take each number minus the mean, and then square the difference. Add together all these squared numbers and then divide by the number of numbers. Like this:
Add together those numbers and divide them by 5:
![\sigma=\frac{10.24+1.44+.64+3.24+3.24}{5}=\frac{18.8}{5}=3.76](https://tex.z-dn.net/?f=%5Csigma%3D%5Cfrac%7B10.24%2B1.44%2B.64%2B3.24%2B3.24%7D%7B5%7D%3D%5Cfrac%7B18.8%7D%7B5%7D%3D3.76)
8/ Sine 50 = n/ Sine 90
8 sine 90 = n Sine 50
8 sine 90 / sine 50 = n
n = 10.4
Answer: 42.9%
Step-by-step explanation:
Percent error is the difference between the measured and known value, which is divided by the known value, and then multiplied by 100%.
Percent error = (Estimated number- Actual number)/Actual Number × 100.
= (60 - 42)/42 × 100
= 18/42 × 100
= 0.429 × 100
= 42.9%
The answer is 11 because if you look at the chart. You can see everything can be divided by 8 and 88 divided by 8 is 11.
