The overlap in the two data sets is low
Answer:
a) (+) × (?) = (+)
(?) = (+)
b) (-) × (+) = ?
? = (-)
c) (?) × (-) = ?
? is undefined
Step-by-step explanation:
a) (+) × (?) = (+)
From the given equation in the question, by dividing both side of the equation by (+), we have;
((+) × (?))/(+) = (+)/(+)
(?) = (+)/(+) = (+)
Therefore, we have;
(+) × (+) = (+)
(?) = (+)
b) (-) × (+) = ?
From the given equation in the question we apply the operation rules as follows;
(-) × (-) = (+)
(-) × (+) = (-)
Therefore;
(-) × (+) = ? = (-)
? = (-)
c) (?) × (-) = ?
From the rules of multiplication, we have;
(-) × (-) = (+)
(+) × (-) = (-)
Therefore, when (?) = (-), ? = +, from which we have;
(?) ≠ ?, which is an error
Similarly, when (?) = (+), ? = -, therefore, (?) and ?, always changes sign
Therefore, the equation, (?) × (-) = ?, is undefined.
I think you would divide the angle measure by two... Does your question give you options (A,B,C,D)?

Step 1: arrange the data points in order
12 14 24 30 35 40 42 50 53 Step 2 : Find the median.
median is 35. Step 3. divide the data points into two : left and right
of median
12 14 24 30 and 40 42 50 53
Step 4: find median of each12 14 24 30 : (14+24)/2 = 1940 42 50 53 : (42+50)/2 = 46
step 5. draw lines on the scale on the median, two other
medians and least and the greatest value
Answer is B.
