Give an equation which describes the intersection of this sphere with the plane z=0z=0.

1 answer:

4 0

C=(x0,y0,z0)C=(x0,y0,z0) and radius rr.

(x−x0)2+(y−y0)2+(z−z0)2=r2(x−x0)2+(y−y0)2+(z−z0)2=r2

Bob discovers a box with 30 identical, used, rechargeable batteries in his attic.

Answer:

a) All of them are out of charge = 9.31x10⁻¹⁰

b) 20% of them are out of charge = 5.529x10⁻⁴

Step-by-step explanation:

This problem can be modeled as a binomial distribution since

There are n repeated trials and all of them are independent of each other.

There are only two possibilities: battery is out of charge and battery is not out of charge.

The probability of success does not change with trial to trial.

Since it is given that it is equally likely for the battery to be out of charge or not out of charge so probability of success is 50% or 0.50

P = 0.50

1 - P = 0.50

a) All of them are out of charge?

Probability = nCx * P^x * (1 - P)^n-x

Probability = ₃₀C₃₀(0.50)³⁰(0.50)⁰

Probability = 9.31x10⁻¹⁰

b) 20% of them are out of charge?

0.20*30 = 6 batteries are out of charge

Probability =₃₀C₆(0.50)²⁴(0.50)⁶

Probability = 5.529x10⁻⁴

Solve the inequality. 6x + 3 > 3x + 30 A) x > 9 B) x > 11 C) x > −9 D) x > −11

ANTONII [103]

Subtract 33 from both sides

6x>3x+30-36x>3x+30−3

Simplify 3x+30-33x+30−3 to 3x+273x+27

6x>3x+276x>3x+27

Subtract 3x3x from both sides

6x-3x>276x−3x>27

Simplify 6x-3x6x−3x to 3x3x

3x>273x>27

Divide both sides by 3

3x>\frac{27}{3}x>

3x> 27

Simplify \frac{27}{3}
