Answer:

  • 2∠15°
  • 2cos(15°) +i·2sin(15°) ≈ 1.93185 +0.517638i

Step-by-step explanation:

Using Euler's formula, the 6th root is easily found.

  (64i)^(1/6) = ((2^6)e^(iπ/2))^(1/6) = 2e^(iπ/12) = 2∠15°

  = 2(cos(15°) +i·sin(15°)) = 2·cos(15°) +i·2·sin(15°) ≈ 1.93185 +0.517638i

Answer: (a) mean = 32.00

(b)Standard error = 0.068

It is expected that the shape will approximately large because n is large.

(c)P(z< 0.60)= 0

Step-by-step explanation:

a. Mean = nP= 0.64× 50 = 32.00(2dp)

P= 0.64

b. Standard error = √ p(1-p)/n

= √0.64(0.36)/50

= 0.068(3dp)

c. Using P(Z<X - U/S)

Where S = standard error

U = mean = 0.64

(c)P(z< 0.60)=

= P( z< 0.60 - 0.64/0.068)

= P( z < -5.88)

= 0.

5x+6y=50<br> -x+6y=26<br> step by step Elimination
slamgirl [31]

Answer:

x=19.998

y=3.333

Step-by-step explanation:

5x+6y=50

-x+6y=26

6y=26+x

x=26-6y

5(26-6y)+6y=50

130-30y+6y=50

130-50=30y-6y

80=24y

y= 3.333

x=26-6y

x=26-(6×3.333)

x=19.998
