Express (2-I) - (-1+3i) in the form of a + ib.
oksian1 [2.3K]

Answer:

=3-4i

Step-by-step explanation:

So we have:

(2-i)-(-1+3i)

First, distribute:

=(2-i)+1-3i

Combine like terms:

=-i-3i+2+1

Add:

=-4i+3

So, in the a+bi format, we will have:

=3-4i

lidiya [134]

Answer:

d. 20

Step-by-step explanation:

Standard deviation is 4.5

Margin error for the problem is 2 hours

Probability 95%, that means that the siginficance level α is 1 – p

α = 1 – 0.95 = 0.05

margin of error (ME) can be defined as follows

ME = Z(α/2) * standard deviation/ √n

Where n is the sample size

Z(0.05/2) = Z(0.025)

Using a z table Z = 1.96

Now, replacing in the equation and find n

2 = 1.96 * 4.5/ √n

2 = 8.82/√n

√n = 8.82/2

√n = 4.41

n = 4.41^2

n = 19.44 ≈ 20
