Answer:

u + v

=2-i + -4+ 5i

=2-4+5i-1i

= -2+4i

u- v

=2- 1i - -4 + 5i

=2+4 +5i-1i

=6+4i

u × v

=2- 1i × -4 + 5i

= -8 +4i +10i -5i

= -8 + 14i - 5i

= -8 + 9i

u ÷ v

= 2- 1i ÷ -4 +5i

= -2+2.5i - 4i - 5

= -2-5 + 2.5i - 4i

A bag holds 12 red marbles, 11 green marbles, 17 blue marbles, and 5 yellow marbles. What is the probability that you will not c
Nataly_w [17]

Hey there! Welcome to Brainly!

Let's see how many marbles we have in total.

12+11+17+5=45

We want to find the probability of selecting a marble that is not blue. Let's see how many marbles aren't blue.

12+11+5=28

We have this probability out of 48.

28/48

We simplify, giving us 7/12 or about 58.33%.

I hope this helps!

Need help very bad :((
RideAnS [48]

Answer:

Step-by-step explanation:

First of all, I can't think of a single exception to this, but when you rotate a figure, the two figures are congruent If all you do is rotate it.

2y/2 = 5/2                Divide both sides by 2

y = 5/2

y = 2.5

2x = 67 degrees    Divide both sides by 2.

2x/2 = 67/2            x = 33.5

3w + 3 =12             Subtract 3 from both sides

3w + 3 -3 = 12-3    Combine

3w = 9                   Divide by 3

w = 9/3

w = 3
