Explore sums of complex

Charra [1.4K]

The two-point A and B will be -1+2i and -2+2i respectively.

<h3>What is the complex number?</h3>

A complex number is one that has both a real and an imaginary component, both of which are preceded by the letter I which stands for the square root of -1.

The complex number is given as;

x+iy

Where x is the real part and iy is the imaginary part.

The two points added to obtained -3 + 4i are;

A = -1+2i

B= -2+2i

The sum of the two points is;

⇒A+B;

⇒-1+2i + -2+2 i

⇒-3 + 4 i

Hence the two-point A and B will be -1+2i and -2+2i respectively.

Morgarella [4.7K]

Answer:386

Step-by-step explanation:

We have given

Smoothing parameter $\left ( \alpha \right )=0.56$

Forecasted demand $\left ( F_t\right )=385$

Actual demand $\left ( D_t\right )=386$

And Forecast is given by

$F_{t+1}=\alpha D_t+\left ( 1-\alpha \right )F_t$

$F_{t+1}=0.56\cdot 386+\left ( 1-0.56\right )385=385.56\approx 386$

$F_{t+2}=0.56\cdot 386+\left ( 1-0.56\right )385.56=385.806\approx 386$

$F_{t+3}=0.56\cdot 386+\left ( 1-0.56\right )385.806=385.914\approx 386$

$F_{t+4}=0.56\cdot 386+\left ( 1-0.56\right )385.914=385.962\approx 386$

Suppose we pick 3 students at random from a class with 10 boys and 15 girls. let x be the number of boys selected and y be the n

zheka24 [161]

The probability of the first pick to be a boy is 10/25.
Let S be the sample space and E be the event of selecting 1 girl and 2 boys.
n(S)=number of ways selecting students of 25.
=²⁵C₃
=25·24·23/3·2·1
=2300
n(E)=(¹⁰C₁·¹⁵C₂)
=[10·(15·14)/2·1
=10500
P(E)=n(E)/n(S)=1050/2300=21/46
