Select the correct answer from each drop-down menu. The graph represents the complex numbers z1 and z2. What are their conjugates? What is the conjugate of their product? The conjugate of z1 is (a)-2-3i (b)-2+3i (c)2-3i. The conjugate of z2 is (a)-5+4i (b)5-4i (c)5+4i . The conjugate of the product of z1 and z2 is (a)-22+23i (b)-2+23i (c)2+23i (d)22+23i.

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
