Step-by-step explanation:

W = 0.5 mv^2  \\ plug \: m = 6 \: and \: w = 783 \\ 783 = 0.5 \times 6 \times  {v}^{2}  \\ 783 = 3 {v}^{2}  \\  {v}^{2}  =  \frac{783}{3}  \\  {v}^{2}  = 261 \\ v =  \sqrt{261}  \\ v = 16.1554944 \\  \huge \red{ \boxed{v = 16.155 \: m {s}^{ - 1} }} \\

Show all work to multiply (6+square root -64)(3-square root -16)
Hunter-Best [27]

Answer:

50

Step-by-step explanation:

- 8i = √-64

8i + 6

- -4i = -√-16

-4i + 3

[8i + 6][-4i + 3] → FOIL

>> -32i² + [24i - 24i] + 18

↑ ↑

-1 0

>>> 32 + 18 = 50

Information on Imaginary Numbers

√-1 = i

-1 = i²

-i = i³

1 = i⁴ [And every other exponent that is a multiple of 4; this cycle then repeats itself every time you go up one number at a time]

sergejj [24]

Solution :

a). The point estimate of proportion of college graduates among women who work at home,

$\hat p =\frac{166}{506}$

  = 0.3281

99.5% confidence interval

$=\left( \hat p \pm Z_{0.005/2} \sqrt{\frac{\hat p (1- \hat p)}{n}} \right)$

$=\left( 0.3281 \pm 2.81 \sqrt{\frac{0.3281 \times  (1- 0.3281)}{506}} \right)$

$=(0.3281 \pm 0.0586)$

$=(0.2695, 0.3867)$
