<u>Answer:</u>
If PQ=RS then PQ and RS have the same length. Hence option D is correct
<u>Solution:</u>
Given that, pq = rs
And, we have to find which of the given options are true.
<u><em>a) pq and rs form a straight angle
</em></u>
We can’t decide the angle in between pq and rs just by the statement pq = rs.
So this statement is false.
<u><em>b) pq and rs form a zero angle.
</em></u>
We can’t decide the angle in between pq and rs just by the statement pq = rs.
So this statement is false.
<u><em>c) pq and rs are same segment.
</em></u>
If two things equal then there is no condition that both represents a single item.
So this statement is false.
<u><em>d) pq and rs have the same length
</em></u>
As given that pq = rs, we can say that they will have the same length
Hence, option d is true.
Question
The table shows the heights in a basketball team.
Height: 198, 199, 200, 201, 202
a.) Work out the mean height of the team. Round you answer to 1d.p.
That, I have worked out is 200.3
b.) A new player joins the team and raises the mean average height to 201cm. Work out the height of the new player.
Answer:
206 cm
Step-by-step explanation:
The sum of the fiven numbers, 198+199+200+201+202=1000
For a mean of 201, the product should be 201*6=1206
The difference of the two is equivalent to the height of the other person hence 1206-1000=206 cm
Therefore, the height is 206 cm

Answer:
15 dollars.
Step-by-step explanation:
That would be 60% of 25
= 25 * 0.6
= 15 dollars.
we will find number of non-zero elements on each rows
and then we add them
First row:
we can see that non-zero elements are
2 , 3.1 , 22 , 9
so, number of non-zero elements in first row =4
Second row:
we can see that non-zero elements are
21 , 3.2 , 6
so, number of non-zero elements in first row =3
Third row:
we can see that non-zero elements are
1 , 42 , 8
so, number of non-zero elements in first row =3
Fourth row:
we can see that non-zero elements are
40 ,4 , 6,14
so, number of non-zero elements in first row =4
Fifth row:
we can see that non-zero elements are
10 , 20 , 13 , 5 , 6.3
so, number of non-zero elements in first row =5
now, we can add them
so,
total number of non-zero elements = 4 +3+3+4+5
so,
total number of non-zero elements is 19...........Answer
