how to get the number 1000 using the number 9 only four times.Any operation is permitted as long as we use only the number 9

suppose i have an undamped harmonic oscillation.what happen to the amplitude and frequency when introducing damping?

A rock is thrown upward with velocity v0, with an angle theta from the horizontal ground.

You may neglect friction in this problem. Gravity g points straight downward, and the

rock is thrown in the positive x-direction.

What is the vertical and horizontal components of the velocity, vtop = (Vx(top)

Vy(top))

at the highest point?

What is the vertical component of the velocity Vy(ground)

when the rock hits the ground?

What is time t-up for the rock to reach the highest point in its trajectory? Show that

the time t-down the rock takes from the highest point back to the ground, on its way down, is same as t-up

let A be a square matrix.Show the following.

if A^3=0 then (I+A) is invertible and (I+A)^-1=I-A+A^2

Hi everyone.Can anyone tell me when the italian movie directed by Tornatore

Let Z~N(0,1).Find x such that P(Z<x)=0.875.Give the answer to 3 significant figures

Hi

Suppose i have 3 coins in a bag:two are ordinary coins,one has head on both sides.

i) i take a coin out of my bag at random and toss it.what is the probability it comes down heads?

ii)Suppose i take a coin out of my bag randomly,toss it,and it comes down heads.What is the probability that the other side is a head?

iii)What is the probability that if i toss the same coin a second time i will get another head?

Thanks i really appreciate if someone could give me an explanation of how to get there

if B and C are events. prove that if B and C are independent then the

(complement of B) and C are independent

there are 2 roads from a to b and two roads from b to c.If each road is closed with probability p and the state of each road is independent of the others.what condition of p ensures that the probability i can't travel from a to c is no more than 1/2

Each member of a squad of 18 cricketers is either a batsmen or a bowler. The squad comprises 10 batsmen and 8 bowlers. A coach chooses a team by picking a random set of 11 players from the squad.

What is the probability that the team contains fewer less than 3 bowlers?

How abour one which is surjective but not injective
