Answer:

The resulting cross sectional area will be circle.

Step-by-step explanation:

If a plane intersects a sphere it will give the cross sectional shape of circle

Whenever a plane intersects a three dimensional figure it will result in two dimensional figure.

The sphere when intersects by a plane will always give the circle no matter where does it intersect from.

4x−3/2 − 5−2x/3 − 3x−4/3 = 5

babunello [35]

Answer:

Step-by-step explanation:

4x - 3/2 - 5 - 2x/3 - 3x - 4/3 = 5

Give all terms least common denominator of 6:

4x(6/6) - 3/2(3/3) - 5(6/6) - 2x/3(2/2) - 3x( 6/6)- 4/3(2/2) = 5(6/6)

24x/6 - 9/6 - 30/6 - 4x/6 - 18x/6 - 8/6 = 30/6

Combine x terms and numerical terms:

2x/6 - 47/6 = 30/6

2x/6 = 77/6 (Add 47/6)

2x = 77 (Multiply both sides by 6)

x = 77/2 = 38.5

jeyben [28]

Answer:

The answer is "0.9258201 or $\bold{ \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times 0.7 }{50}}}}$ ".

Step-by-step explanation:

$\to P= 30 \ \%\\\\ \to x= 18 \\\\ \to n=50\\\\\\\hat p= \frac{x}{n} = \frac{18}{50} = 0.36 \\\\\bold{Formula:}\\\\X= \frac{\hat p -p}{\sqrt{\frac{p \times (1-p)}{n}}}\\\\$

$= \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times (1-0.3)}{50}}}\\\\= \frac{0.36 -0.3}{\sqrt{\frac{0.3 \times 0.7 }{50}}}\\\\= \frac{0.36 -0.3}{\sqrt{\frac{0.21}{50}}}\\\\= \frac{0.06}{\sqrt{0.0042}}\\\\= \frac{0.06}{0.064807407}\\\\= 0.9258201$
