Hi
arithmetic serie mean that to change from a rank to an other, you add "r"
So : if 6 is S1, and 2 is pace,
<u>then you need 8 hops to go from S1 to S9.</u>
<u> so you 'r going to add the reason 8 times. </u>
so : S9 = 6 + 8 * 2 = 6 + 16 = 22
conclusion : S9 = 22
To do this addition mentally, you should do like this:
31 requires 9 more to become 40 and since we have a nine in our question, we would first do 31 + 9 = 40. Now you would finish it off with the remaining number which is six. 40 + 6 = 46.
<u>Steps</u>:
31 + 9 = 40
40 + 6 =46
Therefore, your answer would 46.
600-225 = 375 students didn't attended the game.
So, the percentage of the people who didn't attented will be (375/600) × 100 = 62.5%
Answer:
p-e< p < p+e
(0.061 - 0.025) < 0.061 < (0.061 + 0.025)
0.036 < 0.061 < 0.086
Step-by-step explanation:
Given;
Confidence interval CI = (a,b) = (0.036, 0.086)
Lower bound a = 0.036
Upper bound b = 0.086
To express in the form;
p-e< p < p+e
Where;
p = mean Proportion
and
e = margin of error
The mean p =( lower bound + higher bound)/2
p = (a+b)/2
Substituting the values;
p = (0.036+0.086)/2
Mean Proportion p = 0.061
The margin of error e = (b-a)/2
Substituting the given values;
e = (0.086-0.036)/2
e = 0.025
Re-writing in the stated form, with p = 0.061 and e = 0.025
p-e< p < p+e
(0.061 - 0.025) < 0.061 < (0.061 + 0.025)
0.036 < 0.061 < 0.086
