Answer:
B
Step-by-step explanation:
Answer:
14: B. 40 C. 40 D. 100
Step-by-step explanation:
a triangle is 180 degrees adding all the angles. The triangle on the top is just a mirror for the bottom and since B and C are the same that equals 80 and when you subtract 80 from 180 you get 100 so that makes D 100.
To double check just add 100+40+40=180
Answer:
No, the teacher won’t be able to make the arrangement
If he tries making the arrangement, 39 students would be left out out of the 1000
Step-by-step explanation:
This will not be possible because, the number of students to arrange is 1000 and it is not a perfect square. So there won’t be a possibility of having the same number of students per row as the number of rows.
If 1000 was a perfect square , it would have been possible
Now, to calculate the number of students that would be left if the teacher proceeded with the arrangement, what we need is that perfect square which is closest to 1000 but less than it.
Since 30 * 30 = 900
The next number to try is 31 * 31 = 961
32 squared won’t work as it is 1024 and the value is greater than 1000
Now, the number of students left would be 1000-961 = 39
5, 7, 7, 8, 10, 11, 12, 15, 17. Q1 = 7, Q2 = 11, Q3 = 15 Q1 = 7, Q2 = 10, Q3 = 13.5 Q1 = 6, Q2 = 9, Q3 = 12 Q1 = 7.5, Q2 = 10.5,

Answer:
Step-by-step explanation:
Given
5, 7, 7, 8, 10, 11, 12, 15, 17.
Required
Determine Q1, Q2 and Q3
The number of data is 9
Calculating Q1:
Q1 is calculated as:
Substitute 9 for N
This means that the Q1 is the mean of the 2nd and 3rd data.
So:
Calculating Q2:
Q2 is calculated as:
Substitute 9 for N
Calculating Q3:
Q3 is calculated as:
Substitute 9 for N
This means that the Q3 is the mean of the 7th and 8th data.
So:
The answer is -17 hope this helps
