<span>(x+3)^2 = x^2 + 69
x^2 + 6x + 9 = x^2 + 69
x^2 + 6x + 9 - x^2 = x^2 + 69 - x^2
6x + 9 = 69</span>
Step-by-step explanation:
The answer is 29 degrees because the outer angle is equal to the inner angles, so the equation would be:
G=P+R and if you substitute you get 56=P+27
Solve it and you get:
P=56-27
P=29

Answer:
Step-by-step explanation:
Given
------------------------------Has a brother | Does not have a brother
Has a sister
--------------------------- 6 ----------------- 8
Does not have a sister -----------2 ------------------ 13
Required
Probability of having a sister and a brother
First, the total number of students has to be calculated;
Total = 6 + 2+ 8 + 13
Total = 29
Number of students that have a sister and a brother is represented with data in row 1 and column 1 i.e. 6
At this point, the probability can then be calculated;
Probability = Number of students that have a sister and a brother divided by Total number of students
Answer:
95% Confidence interval of the standard deviation: 3.33 ≤ σ ≤ 8.85
Step-by-step explanation:
Sample size = 10
Degrees of freedom = 10-1 = 9
For a 95% confidence interval, we have α=0.05, which gives 2.5% of the area at each end of the chi-square distribution.
We calculate the chi-square values for a 95% confidence interval
Value of chi-square_0.975 = 2.70
Value of chi-square_0.025 = 19.02
We then evaluate [/tex] for the two values of chi-square.
Then we have:
[/tex]
With these results we can express the confidence interval as
3.33 ≤ σ ≤ 8.85
<em>Answer,</em>
<em><u>17lbs = 7.71107kg</u></em>
<em>Rounded it would be, </em><em><u>7.7 Kg</u></em>
<em>Explanation,</em>
<em>If you know that 1lbs to kg is, </em><em>0.453592 kg</em><em> just multiply that by </em><em>17 lbs.</em>
<em>Then you will get, </em><em>7.71107 kg</em>
<em>If you would like a rounded answer, just round it & you will get </em><em>7.7 kg</em>
<u><em>Hope this helps :-)</em></u>
