The ratio in which girls and children are born is 2 to 5, then the number of girls born is 10
<u>Solution:</u>
Given that the ratio of girls and children is = 2 : 5
Let the number of girls born be "2x" and number of children born be "5x"
Given that 35 are born, So total born = 35
Hence we get,
2x + 5x = 35
7x = 35
x = 5
So number of girls born is:
Hence number of girls born is 10
Answer:
Option 3rd is correct that is
Step-by-step explanation:
Since, the pennant has three points it is in triangular shape since, have three points
Triangle is enclosed figure.
As we know the sum of interior angles of triangles is
Therefore, Option 1,2,4 are discarded.
Hence, Option 3rd is correct.

It is convenient to let a spreadsheet or graphing calculator do the tedious math for you. (See the attachment.)
_____
The sum of the numbers is 56, so their average is 56/7 = 8. Then the absolute deviations from average are ...
... 8, 5, 2, 1, 3, 5, 6
and the total of these is 30. The mean absolute deviation is this sum divided by the number of numbers, 7, so is ...
... 30/7 = 4 2/7

<em>More about Absolute Deviation from Average</em>
"Absolute" here refers to the absolute value function, which drops the sign of a negative number. The absolute deviation of the data value 0 is ...
... |0 - 8| = |-8| = 8
For 3, it is ...
... |3 - 8| = |-5| = 5
