Answer:
Interquartile range
Step-by-step explanation:
The interquartile range gives the middle half of a dataset. It is obtained by subtractionng the value of the lower quartile (Q1) from the value of the upper quartile(3rd quartile).
Interquartile range (IQR) = Q3 - Q1
WHERE ;
Q3 = 3/4 * (n+1)th term and the first quartile (Q1) is given as ;
Q1 = 1/4 * (n+1)th term
n = size of data Given.
Answer:
5y + x = 35
Step-by-step explanation:
5y= 10 - x
y = 2 -1/5x
thus gradient m = -1/5
the eqn would be y = -1/5x + 7 or 5y + x = 35

Answer:
6t = -21
Step-by-step explanation:
3t-7 = 5t simplifies by subtracting 5t on both sides, then adding 7 on both sides:
3t -5t -7 +7 = 5t-5t+7
-2t = 7
t = -7/2
Then 6t = 6*-7/2 = -21
