Find the complex conjugate of 10+ 61.
a. -10 + 61
b. 10-61
C.-10-61
d. 6 - 107

b. 10 - 61

Step-by-step explanation:

10 + 61 is 71

We need to change the addition sign to subtraction.

10 -  61= -51

We need to find an equation that is equal to -51.

a. -10 +61

That equals 51, which is not 71, which means it is not letter a.

b. 10 - 61

That equals -51, which is not 71, which means it is not letter b.

c. -10 - 61

That equals -71, which is not 71, which means it is not letter c.

d. 6- 107

That equals -101, which is not 71, which means it is not letter d.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500
